6 2015 Executive Summary: Campgrounds are high priority areas for invasive plant surveillance and management efforts within the Adirondack Park as many outbreaks originate in these locations. This is primarily due to the high levels of human disturbance and incoming recreational traffic associated with campgrounds. Identifying invasive plant infestations at their point of introduction allows for early detection and rapid response (ED/RR) management efforts and can reduce or eliminate spread to uninvaded areas such as the adjacent Adirondack Forest Preserve. Over the course of the 2015 field season, 40 state campgrounds and many intensive-use areas within the Adirondack Park were inventoried for invasive plant species. Infestations of priority species including garlic mustard (Alliaria petiolata), purple loosestrife (Lythrum salicaria), yellow iris (Iris pseudacorus), Japanese knotweed (Fallopia japonica), common reed or phragmites (Phragmites australis), and other invasive plants, were managed via hand removal or mapped using GPS and visual survey techniques. Garlic mustard was the most commonly detected invasive plant species documented at intensive use areas in the Adirondacks during the 2015 season. It was observed at 50% of the New York State Department of Environmental Conservation (NYSDEC) campgrounds inventoried in Garlic mustard was usually found in small, dense pockets at several individual campsites throughout the larger campground. In general, these infestations were usually of a manageable size and could be cleared by a single person in less than one day. If management efforts are continued for the next several years at these locations, there will likely be significant reduction in the density and abundance of plants observed. Noticeable declines can already be observed at several campgrounds. Annual surveillance of the campgrounds and campsites that remain uninvaded will allow for the early detection of species, as new introductions occur, which will bolster the effectiveness of control efforts. While most campgrounds contained small pockets of plants, there were also several campgrounds that held large, dense infestations of garlic mustard. Such locations included Nicks Lake, Golden Beach, Lake George Battleground, Rogers Rock, and Hearthstone Point, among others. These campgrounds will require many years of high intensity management for measureable success to be achieved. Second to garlic mustard, purple loosestrife was observed at approximately 28% of all NYSDEC campgrounds visited in At most of the campgrounds, infestations were small remnants of former large infestations. The success of management in past years was evident. However, several campgrounds still contained large infestations that will require additional years of management or the release of bio-control agents to achieve a desirable reduction. Two campgrounds on the edge of Lake Champlain (Ausable Point and Crown Point) have dense infestations of purple loosestrife that are unlikely to be reduced with annual digging and hand

7 2015 pulling. Both Ausable Point and Crown Point are situated in a region where purple loosestrife is widely distributed. Therefore, any managed areas are prone to reinvasion in subsequent years. The use of biological controls should be strongly considered for these locations. Japanese knotweed was observed at five campgrounds and common reed grass at two campgrounds in Each of these individual infestations was 0.01 acres or less in size and could likely be contained or eradicated with consecutive herbicide treatments. If possible, herbicide treatments should be performed on these infestations in the off-season, when the campgrounds are not open to the public. Overall, successful control is highly probable for garlic mustard and purple loosestrife infestations at most of the state campgrounds within the Adirondack Park through continued annual management. However, there are notable exceptions at select campgrounds that harbor particularly large infestations. Progress achieved at the campgrounds by historic management efforts was set back in 2010 and 2011 when seasonal capacity was limited and invasive plants were left unmanaged; reinforcing the importance of annual monitoring and management. The majority of Japanese knotweed and common reed infestations have been left unmanaged since effective control of these species usually requires the application of herbicides. However these species still do not exhibit a significant presence at the campgrounds and could likely be eliminated with sustained herbicide treatments. Chemical control of these species should be considered at all state campgrounds within the Park in future years. Many state campground employees were unaware that their campground was infested by an invasive plant and were not familiar with invasive plant identification and management strategies. To aid in the battle against invasive plants at the state campgrounds, it would be beneficial to offer trainings in the identification and management of common invasive plants for campground staff at the beginning of the season. Ideally, this would occur at all of the campgrounds, but it is especially important for campgrounds that are not currently invaded, but that are located adjacent to heavily-infested campgrounds. This is also especially important for campgrounds surrounded by forest preserve or other NYSDEC administered lands. 7

8 2015 Introduction: Overview: In the summer of 2006, the NYSDEC supported a seasonal Operations Invasive Species Specialist position to implement annual invasive plant inventories and management at state campgrounds in the Adirondack Park. State campgrounds are classified as intensive use areas within the Park and as such are highly susceptible to invasion by invasive plants. Once campgrounds become infested, they can serve as a source from which invasives spread into other areas of higher conservation value such as forests, rivers and wetlands within the forest preserve. The spread of invasive plants at campgrounds can occur through vegetative growth, seed dispersal on campers gear and clothing, root and stem fragmentation, transfer of infested soils or equipment, and wind dispersal. As a result, the Adirondack Park Invasive Plant Program (APIPP) and NYSDEC identified state campgrounds as priority areas to survey for and manage invasive plants within the Adirondack Park. The Invasive Species Specialist performed annual surveys, management, and documented findings through the 2009 field season. In 2010, funding for the position was unavailable, and data collection and management efforts were halted. Much of the progress that had been made in controlling garlic mustard and purple loosestrife was set back as plants regrew and infestations went unmanaged. In 2011, APIPP initiated limited management, collecting data and managing several of the infestations at high priority campgrounds. From , NYSDEC, APIPP, and the State University of New York College of Environmental Science and Forestry (SUNY ESF) have coordinated a seasonal internship in order to revitalize an invasive plant inventory and management program at state campgrounds within the Adirondack Park. Additional staff capacity was provided by the Student Conservation Association (SCA) to assist with management efforts of garlic mustard and purple loosestrife at some of the most densely infested campgrounds. The following report documents the distribution and management of invasive plant species at New York State campgrounds within the Adirondack Park during the 2015 field season. Although this project focused primarily on state campgrounds, an additional project included conducting invasive plant inventories at trailheads throughout the Adirondacks. The results of this project are also described herein. Treatment Procedures Used for Common Invasive Plants: Garlic Mustard Second year plants were pulled up by the root and placed in thick contractor garbage bags. The bagged plant material was transported to the APIPP office in Keene Valley and placed in the sun for at least two weeks or until the contents had liquefied and no viable plant material remained. At the end of the season, these bags were disposed of at the local transfer station. 8

9 2015 Purple Loosestrife Plants were pulled or dug up to remove as much of the root system as possible. Plants were placed in thick contractor garbage bags and transported to the APIPP office in Keene Valley where they were set out in the sun for at least two weeks, until the contents had liquefied and no viable plant material remained. At the end of the season, these bags were disposed of at the local transfer station. Japanese Knotweed and Phragmites (Common Reed Grass) Infestations were mapped with a GPS and uploaded into APIPP s Weeds Information Management System (WIMS), a database containing information about the location and size of infestations of priority invasive plant species within the Adirondack Park. No management was performed for these species by the Invasive Species Specialist, as herbicide is generally required to provide effective control. APIPP s Terrestrial Invasive Species Project Coordinator organized treatment of some of the higher priority sites. Wild Parsnip Plants were pulled up by the root or cut off at the base and placed in thick contractor garbage bags. The bagged materials were transported to the APIPP office in Keene Valley where they were set out in the sun for at least two weeks, until the contents had liquefied and no viable plant material remained. At the end of the season these bags were disposed of at the local transfer station. NOTE: Protective clothing including long sleeves, long pants, and gloves (at a minimum) should be worn when treating this species. The sap of wild parsnip is toxic and can cause phyto-photo-dermatitis if it comes in contact with exposed skin. Bush Honeysuckle, and Japanese Barberry The presence of these invasive plants was noted among the campgrounds, but infestations were managed only when plants were found sporadically around the campground. These species are of a lower priority level because they are locally widespread and can be spread long distances through the deposit of their berries and seeds by birds. Management of larger infestations was conducted only when adequate time remained after management and inventories of other, higher priority species had been performed. To manage these species, the plants were pulled up by the base, with efforts made to remove the entire root system. Medium sized plants often required the use of a honeysuckle popper for extra leverage and grip. Extracted plants were hung upside down in nearby trees so they would dry out and decompose. Large plants were left in place with a noted recommendation to perform a cut stump herbicide treatment in the future. Yellow Iris Small plants were pulled and larger plants were dug up to remove as much of the root system as possible. Plants were placed in thick contractor garbage bags and transported to the APIPP office in Keene Valley where they were set out in the sun for at least two weeks, until the contents had liquefied and no viable plant material remained. At the end of the season, these bags were disposed of at the local transfer station. 9

13 Indian Lake Working Circle 2015 Indian Lake Working Circle Brown Tract Pond State Campground Invasive Plant Species: garlic mustard Locations: Garlic mustard was found and pulled from sites 48, 81 and 82. In the past, bush honeysuckle was found at site 32, bull thistle at site 17, and crown vetch between sites 34 and 35; none of these species were observed this year. A total of 12 second-year garlic mustard plants were pulled from the campground. In 2015, Brown Tract Pond State Campground was managed with help from an SCA crew. This made for very quick work at the campground and may not be needed in future years if the current management trend continues. This campground should be monitored yearly to combat the current garlic mustard infestation. It is especially imperative to treat the garlic mustard infestation on the elevated section of the campground at sites 81 and 82. These infestations could rapidly spread downhill if left untreated, potentially infesting other campsites. Eighth Lake State Campground Invasive Plant Species: garlic mustard, bush honeysuckle Locations: Garlic mustard is widely dispersed throughout the Eighth Lake Campground and was found at site numbers 8, 15, 17, 23, 30, 31, 33, 35-37, 79, 80, 88, 91, 95, 100, 108 and 113. It was also found behind the bathroom between sites 38 and 40. A total of 473 second-year garlic mustard plants were removed from the campground. The density of the garlic mustard infestations at this campground has been reduced in the last 3 years, indicating that the treatment performed from 2012 to 2014 was effective. This 13

14 Indian Lake Working Circle 2015 campground should still be monitored annually in order to combat the garlic mustard infestation. This campground was managed with the assistance of an SCA crew and while this resource was helpful this year, it may not be necessary in future years if the current trend continues. Offering an invasive species identification and management seminar (focused on garlic mustard) for the staff here would be useful if time and resources are available. This would increase awareness among the staff about invasive plants, and their help could contribute to the success of future management efforts. Bush honeysuckle was found scattered throughout the campground, but was not managed. Forked Lake State Campground Invasive Plant Species: bush honeysuckle Locations: A few honeysuckle bushes were found surrounding the parking area near the Facility Supervisor s cabin. There was no management conducted of the honeysuckle at this campground due to the size of the plants. This campground should be monitored annually to remove any new, small bush honeysuckle plants present and to address any new invasive species that may establish. Garlic mustard is present at other campgrounds in the area. Golden Beach State Campground Invasive Plant Species: garlic mustard Locations: Garlic mustard was found covering much of the campground, although the number of plants has been greatly reduced from previous years. Specifically, garlic mustard was removed from sites 2, 4, 5, 9, 11, 14, 18, 20, 22, 41, 43, 45, 47, 49, 52, 53, 55, 60, 62, 64, 65, 67, 74, 82, 83, 85-87, 91, 93-95, 104, 108, 109, 111, 116, 118, 131, 132, 140, 172, 173, 178, 181 and 182. Garlic 14

15 Indian Lake Working Circle 2015 mustard was also found at the bathroom behind site 119 and in the streambed between sites 96 and 184. A total of 823 second year garlic mustard plants were removed from the campground this year. This campground should be monitored yearly in order to combat the garlic mustard infestation. Management was completed with the aid of a crew from the SCA. If this resource is available in the future, it would be advisable to use a crew again to reduce the time needed to complete management. Many garlic mustard rosettes were observed, but not all were pulled; these plants will need to be removed next summer before they go to seed. Offering an invasive species identification and management seminar (focused on garlic mustard) for the staff here would be useful if time and resources are available. This would increase awareness among the staff about invasive plants, and their help could contribute to the success of future management efforts at this campground. Indian Lake Islands State Campground Invasive Plant Species: purple loosestrife Locations: Purple loosestrife was removed from a small bay between sites 26 & 29, site 17, and along the eastern shoreline adjacent to the boat launch. Approximately 10 purple loosestrife plants were pulled from isolated patches along the lake shore and 10 contractor bags of plants were removed from the large patch adjacent to the boat launch. The first recorded inventory of this campground was completed in 2015 with assistance from the SCA. The crew used canoes to survey all sites located on Indian Lake in addition to the shoreline between campsites. While possible to complete in a week using canoes, access to a motorboat would greatly increase the efficiency of this survey. 15

16 Indian Lake Working Circle 2015 Lake Durant State Campground Invasive Plant Species: garlic mustard, bush honeysuckle Locations: Garlic mustard was found at sites 2, 35 and 36. Bush honeysuckle is fairly prevalent at the campground, especially in and around the picnicking, swimming and boat launch areas. A total of 203 second year garlic mustard plants were removed from this campground, as well as many rosettes. No bush honeysuckle plants were removed. This campground should be monitored annually to combat the current garlic mustard infestation and prevent new, small, easily pulled honeysuckle bushes from taking hold. Due to the relatively widespread honeysuckle infestation, large honeysuckle bushes should be managed only if extra time and resources remain after the higher priority invasive species at this and other campgrounds (such as garlic mustard) have been removed. Lewey Lake State Campground Invasive Plant Species: garlic mustard Locations: Garlic mustard was found and removed from sites: 13, 20, 36, 57, 59, 101, 149, 167, 186, 187, 199, 205 and 209. Purple loosestrife was removed from sites 18 and 19, which are located on the shoreline of Indian Lake. A total of 261 second year garlic mustard plants and 60+ purple loosestrife plants were removed from the campground. This campground should be monitored annually to combat the current garlic mustard and purple loosestrife infestations. Many garlic mustard rosettes were observed, but not all were pulled due to time constraints. These plants will need to be removed by midsummer 2016, before they go to seed. 16

17 Indian Lake Working Circle 2015 Shoreline areas and wetland sites in the campground should be carefully monitored for purple loosestrife emergence due to their close proximity to infestations detected on Indian Lake this year. Monitoring should occur in early to mid-august when plants are in full bloom. The assistant caretaker at this campground is aware of the garlic mustard and purple loosestrife infestations and is educated in the proper management strategies for these species. She has been teaching her staff about the invasive plants present at the campground, which will be a tremendous asset to the success of long term management program. Limekiln Lake State Campground Invasive Plant Species: garlic mustard, bush honeysuckle Locations: Garlic mustard is spread throughout the campground. It was found at sites: 11, 25, 52, 82, 131, 166, 168, 193, 202 and 214. Honeysuckle was detected sporadically throughout the campground. A total of 222 second year garlic mustard plants were pulled from the campground. This campground should be monitored annually in order to combat the garlic mustard infestation present. Management was completed with the aid of a crew from the SCA. While helpful, the number of plants found at the site no longer necessitates the extra help and this resource may not be needed if the current trend continues. Many garlic mustard rosettes were observed, but not all were pulled; these plants will need to be removed next summer before they go to seed. Offering an invasive species identification and management seminar (focused on garlic mustard and bush honeysuckle) for the staff here would be useful if time and resources are available. This would increase awareness among the staff about invasive plants, and their help could contribute to the success of future management efforts at this campground. Due to the relatively widespread honeysuckle infestation, large honeysuckle bushes should be removed only if extra time and resources remain after the higher priority invasive species at this and other campgrounds (such as garlic mustard) have been removed. Small, easily removed bushes should be removed before they get a chance to mature and fruit. 17

18 Indian Lake Working Circle 2015 Tioga Point State Campground: Invasive Plant Species: none observed This campground was surveyed for invasive plants for the first time in Due to its remote location and the present absence of invasive species, it should only be monitored if time and access to a boat are available. 18

19 Northville Working Circle 2015 Northville Working Circle Caroga Lake State Campground Invasive Plant Species: garlic mustard, yellow iris, Phragmites, purple loosestrife, Japanese knotweed, Japanese barberry Locations: Garlic mustard was found and removed from sites 3, 52 and 75. Infestations of Phragmites occur behind sites 90 and 92. Yellow iris was found along the stream behind site 123, with the infestation stretching down most of the stream to the lake. It is also established along the lakeshore adjacent to the boat launch area, stretching behind site 125 and onto the neighboring private property. Purple loosestrife was found at the outlet of a stream next to the boat launch and in a small stand of trees at the southern end of the beach parking lot. A growing infestation of Japanese knotweed was found along the fence across from sites 144 and 146, and a larger patch was detected behind sites 153 and 155, adjacent to a main road. Japanese barberry was identified between sites 56 and 57. A total of 20 second year garlic mustard plants were pulled from the campground. Four contractor garbage bags of yellow iris were removed from the stream behind site 123 and along the lake shore, but complete management was not feasible due to time constraints and high abundance of plants. A total of 50 purple loosestrife plants were removed. Minor Gallerucella beetle damage was present on some of the purple loosestrife plants that were removed. Gallerucella beetles are a commonly released bio-control for purple loosestrife. Two Japanese barberry shrubs were pulled and hung upside down in nearby trees to dry and decompose. Due to the southerly location of this campground in the Adirondack Park, it becomes very busy during mid-summer and should be monitored early in the season if possible. The campground should be monitored annually to contain and hopefully eliminate the currently small garlic mustard infestation. Many garlic mustard rosettes were observed, but not all were pulled; these plants need to be removed next summer before they go to seed. Dedicating an extra staff member for one day of yellow iris management in 2016 would be a tremendous asset in managing the infestation at this location. The Phragmites and Japanese knotweed infestations should be treated with herbicide in 2016, if possible, to limit their growth and spread throughout the campground and surrounding areas. Japanese barberry bushes should be pulled and left to dry and decompose, as they present a 19

20 Northville Working Circle 2015 potential hazard to campers due to their spines. Large infestations of this plant can also provide excellent tick habitat. A second monitoring visit should take place in mid-august to remove purple loosestrife while it s in full bloom. Although the size of the infestation has fluctuated in past years, the plants observed this year were small and heavily stressed due to the observed beetle damage. With continued monitoring and management, eradication is a realistic possibility. Little Sand Point State Campground Invasive Plant Species: garlic mustard, Japanese knotweed, bush honeysuckle, Japanese barberry Locations: Garlic mustard was found and removed from sites: 22A, 24 and 48. Two patches of Japanese knotweed are present just behind the registration booth at the campground s entrance. The first patch is bordering site 4, while the second borders sites 5 and 6 and extends down a stream towards the lake. Bush honeysuckle is scattered throughout the campground, while Japanese barberry was detected only at site 57. A total of 160 garlic mustard plants were removed from the campground. Two Japanese barberry plants were pulled and hung upside down in nearby trees to decompose. This campground should be monitored annually to combat the current garlic mustard infestation. Many garlic mustard rosettes were observed, but not all were pulled; these plants will need to be removed next summer before they go to seed. The Japanese knotweed infestations should be treated with herbicide next year, if possible, to limit their growth and expansion throughout the campground and surrounding areas. Japanese barberry was identified for the first time at this campground in Annual monitoring should be conducted to detect any reemerging plants. This species presents a potential health hazard to campers due to its thorns and large infestations can create excellent tick habitat. Monitoring for purple loosestrife should also be conducted along the shoreline on an annual basis as plants have been found at adjacent campgrounds that are also located on Piseco Lake. 20

21 Northville Working Circle 2015 Moffitt Beach State Campground Invasive Plant Species: garlic mustard, purple loosestrife, Phragmites, bush honeysuckle Locations: Garlic mustard was only found on the western half of the campground, past the private property at sites 180, , , 212, 214, 224, and 226. Purple loosestrife was found on the eastern side of the campground, just before private property. This infestation occurs at the edge of the grassy area along the north end of the beach. A very large patch of purple loosestrife was found in the area surrounding sites and the new waste area that extends back into the woods. A new purple loosestrife infestation was found at a fill pile near the entrance booth and shower house. A small patch of Phragmites was found along the sandy area near site 106. Bush honeysuckle was present throughout the campground. A total of 503 second year garlic mustard plants were pulled from the campground. 504 purple loosestrife plants were removed from the campground before management was terminated due to time constraints. The infestations at the grassy area near the beach and the fill pile are manageable, but the purple loosestrife near the new waste area is extensive and should be considered a candidate for biological control. Bush honeysuckle was only managed if the plants were small. These plants were pulled by the roots and hung upside down in a nearby tree to dry and decompose. Extensive management should only be conducted if time presents itself, as higher priority invasive plants (garlic mustard and purple loosestrife) are present at this campground. This campground should be monitored annually to combat the current garlic mustard infestation. Many garlic mustard rosettes were observed, but not all were pulled. These plants will need to be removed next summer before they go to seed. Due to the current state of the purple loosestrife infestation, mechanical treatment methods are not advised. A release of Gallerucella beetles is a viable control strategy for this location. The purple loosestrife in the grassy area near the beach and the fill pile should continue to be managed by pulling/digging as long as the infestation remains small. 21

22 Northville Working Circle 2015 Northampton Beach State Campground Invasive Plant Species: Japanese barberry Locations: Japanese barberry was found at site 124. A single Japanese barberry bush was removed from the campground this year. Garlic mustard has been found at this site in previous years, but no plants were detected in All locations known to be previously invaded should be monitored closely for re-emergence. This was the first year that Japanese barberry was detected at this campground. Continued monitoring should occur to prevent it from gaining a foothold. This species poses a health risk to patrons due to its thorns and large infestations can provide excellent tick habitat. Point Comfort State Campground Invasive Plant Species: garlic mustard Locations: Garlic mustard was found and removed from site 49. A total of 3 second year garlic mustard plants and several rosettes were removed from the campground. This campground should be monitored annually to combat and hopefully eliminate the current infestation of garlic mustard. Monitoring for purple loosestrife along the shoreline should be conducted annually as plants have been found at adjacent campgrounds that are also located on Piseco Lake. 22

23 Northville Working Circle 2015 Poplar Point State Campground Invasive Species Present: purple loosestrife Locations: Purple loosestrife was found and removed from the mouth of a creek behind site 4. A total of 4 purple loosestrife plants were removed from the campground this year. This campground should be monitored annually to address any re-emerging purple loosestrife plants. Both garlic mustard and Japanese barberry have been found here in previous years, so close monitoring should be completed to detect any reemergence. Sacandaga State Campground Invasive Plant Species: Japanese knotweed Locations: A single garlic mustard plant was observed at site 101 in 2013, but no plants were detected at this site in 2014 or Three patches of Japanese knotweed occur along the Route 30 right-ofway and spread down into the campground behind sites 30, 32 and 34. Herbicide treatments of the Japanese knotweed within the ROW have been conducted by APIPP s terrestrial response team since These patches have been reduced significantly in size and density, but resprouts were observed prior to treatment this year. The caretaker and campground staff has been active in the management of the Japanese knotweed at the campground. For the past several years they have cut all of the knotweed on campground property at ground level, gathered the stems, dried and burned them. This repeated effort has yielded impressive results. In addition the sections that are growing in the ROW along State Route 30 have been treated. This campground should be monitored annually for garlic mustard, especially at site 101 where it was documented in The Japanese knotweed infestations should be monitored and mapped annually to document their reductions over time. A follow up treatment on the patches of 23

24 Northville Working Circle 2015 Japanese knotweed should be performed if any resprouting occurs to prevent them from growing to their former state. Monitoring for purple loosestrife should be conducted along the Sacandaga riverbank in mid-august to make sure that it does not become established. 24

25 Ray Brook Working Circle 2015 Ray Brook Working Circle Ausable Point State Campground Invasive Plant Species: purple loosestrife, bush honeysuckle Locations: This campground has one of the most extensive infestations of purple loosestrife present at any of the state campgrounds described in this report. Part of the problem is the massive infestation of purple loosestrife in the adjacent Ausable Marsh Wildlife Management Area, which has spread onto the campground. The most densely invaded parts of the campground are the marshy areas on either side of the entrance road near the registration booth. A small infestation was found in the past between sites 102 and 106, but was not observed in 2014 or Additional purple loosestrife plants were observed across the river from the car top boat launch, however this is not on campground property. No purple loosestrife was managed at this campground due to the size of the infestation and the high likelihood of recolonization. Bush honeysuckle was also left unmanaged due to its widespread distribution. This campground should be monitored annually to prevent the establishment and spread of new invasives. Due to the current state of the purple loosestrife infestation, mechanical treatment methods are not advised, but a biological control of Gallerucella beetles should be considered. This is likely the most cost- and time- effective option available to treat this large infestation. Buck Pond State Campground Invasive Plant Species: None observed This campground should be monitored annually for new infestations of invasive plants. 25

26 Ray Brook Working Circle 2015 Crown Point State Campground Invasive Plant Species: purple loosestrife, bush honeysuckle and wild parsnip Locations: An extensive infestation of purple loosestrife was observed at this campground with many plants growing along the shore of Lake Champlain. Wild parsnip heavily infests much of the campground, especially on steep banks near sites 2, 3, 5, 6, 11, 23, near the parking lot for the lighthouse, and in a patch near the maintenance center. No management was completed at this campground, due to the size of the infestations and the high likelihood of recolonization by purple loosestrife and wild parsnip. This campground should be monitored annually for garlic mustard as it was found at site 14 for the first time in 2014, but was not observed this year. This campground should be monitored annually for wild parsnip and, if resources allow, the infestations should be managed. Wild parsnip sap is phototoxic and poses a health hazard to campground patrons and staff. It should be pulled up by the root and removed from the grounds sometime in early to mid-june, while still in flower. Pulling should be conducted in long sleeves, long pants, and with gloves to prevent exposure to the hazardous sap. If possible, an extra person or crew would be helpful in the management of this large infestation. A second visit should take place in mid-august to document the existing purple loosestrife infestation at the campground. However, this is a relatively low priority purple loosestrife infestation to manage because it is widespread in the surrounding area and re-invasion is likely to occur following management. Biological control with Gallerucella beetles should be considered. 26

27 Ray Brook Working Circle 2015 Fish Creek Pond State Campground Invasive Plant Species: bush honeysuckle Locations: Bush honeysuckle was found scattered throughout the campground. Management was only performed on small, isolated honeysuckle plants. Purple loosestrife was documented for the first time at this campground last year, but was not observed this season. This campground should be monitored annually to document potential reemergence, as well as invasion by other species. Garlic mustard is a high priority for monitoring efforts as it has been documented in the past at nearby Rollins Pond Campground. If time allows, manageable honeysuckle bushes should be pulled and hung upside down on nearby trees to dry. Lake Eaton State Campground Invasive Plant Species: bush honeysuckle Locations: Bush honeysuckle was found sporadically throughout the campground. Several bush honeysuckle plants were pulled by the roots and hung upside down in nearby trees to dry and decompose. Garlic mustard has been observed and managed at this campground in previous years, but none was found this season. Close monitoring should be conducted in the future to detect any reemerging plants and prevent new invasive plants from gaining a foothold. 27

28 Ray Brook Working Circle 2015 Lake Harris State Campground Invasive Plant Species: purple loosestrife Locations: Purple loosestrife is established in two main locations at this campground. The first infestation occurs along the densely vegetated shoreline, spreading into the water in front of sites The second infestation is in a less vegetated area along the shore near the old beach which is currently closed to campers. 503 purple loosestrife plants were pulled from the campground this year. This campground should be monitored annually around mid-august for any reappearing purple loosestrife plants, as well as for signs of other invasive plants. While the infestation on the old beach has remained manageable, control of the shoreline infestation has become infeasible, partially due to the dense brush that restricts access to it. This location should be considered a candidate for biological control with Gallerucella beetles. Lincoln Pond State Campground Invasive Plant Species: garlic mustard, purple loosestrife Locations: Garlic mustard was found and removed from site 17 as well as the hill behind the site. Purple loosestrife was found along the stream leading from the parking lot to the pond and along the forest edge leading to the boat rentals. A total of 9 second year garlic mustard plants were removed from site 17 and the surrounding area. A total of 163 purple loosestrife plants were removed from the campground. This campground should be monitored annually so that the garlic mustard can be contained to site 17 and hopefully eliminated from the campground in the coming years. Monitoring of the purple loosestrife should be conducted around mid-august while the plants are in full bloom. An abundance of black locust trees was noted at this site in 2014, but no management has been 28

29 Ray Brook Working Circle 2015 performed to date. The ramifications of this species on the local environment should be explored to determine if management is needed. Meacham Lake State Campground Invasive Plant Species: None observed This campground should be monitored annually for new infestations of invasive plants. Garlic mustard, yellow iris, and wild chervil have all been identified at this facility in previous years. Meadowbrook State Campground Invasive Plant Species: bush honeysuckle and Japanese barberry Locations: Garlic mustard was documented at site 20 in 2013, but was not detected in 2014 or this year. Japanese barberry was found at site 2. Bush honeysuckle is present in many places throughout the campground. Two Japanese barberry shrubs were pulled and hung upside down in nearby trees to decompose. Management of the honeysuckle was not undertaken due to the size of the infestation. This campground should be monitored annually to make sure that garlic mustard and Japanese barberry do not reappear. Paradox Lake State Campground Invasive Plant Species: garlic mustard, purple loosestrife Locations: Garlic mustard was found and removed from sites 14, 30, 48 and 50. The drainage area near site 50 also contained a large infestation of garlic mustard. Purple loosestrife infests the marshy area to the right side of the boat launch and extends a short way down the shoreline. A second patch 29

30 Ray Brook Working Circle 2015 of purple loosestrife is located to the left of the sandy beach area near the boat rentals, extending a short distance into the adjacent forest. A total of approximately 100 second year garlic mustard plants and 189 purple loosestrife plants were removed from the campground. The purple loosestrife located near the boat rentals had damage from Gallerucella beetles and was left unmanaged. This campground should be monitored annually to combat the current garlic mustard infestation and to detect the presence of new invasives. Many garlic mustard rosettes were observed, but not all were pulled; these plants need to be removed next summer before they go to seed. This campground was managed with the assistance of an SCA crew this year, but due to the significant decrease in plants from previous years, this resource will most likely not be necessary in the future. The campground should be re-visited in mid-august to remove any returning purple loosestrife. Poke-O-Moonshine State Campground Invasive Plant Species: None observed This campground is currently closed to the public and not in use by the state. Since no invasive plants were observed here in the past, and this area will no longer be in frequent use as a campground, it was not surveyed this year and probably does not require annual monitoring unless the campground reopens. However, Poke-O-Moonshine Mountain Trailhead, located at the far left side of the former campground, is still in use and should still be monitored annually for invasive plants. This location was not surveyed in 2015 and should be a priority for monitoring in 2016.Putnam Pond State Campground Invasive Plant Species: garlic mustard Locations: Garlic mustard was found and removed from sites 50, 58, and 59. Another patch was found and removed from the path that extends from the parking area to the day use shelter. No purple loosestrife was observed at this campground for the third consecutive year. 30

31 Ray Brook Working Circle 2015 A total of 331 second year garlic mustard plants were removed from the campground. This campground should be monitored annually for garlic mustard. Purple loosestrife has been found at this campground in the past, but has not been observed for 3 years. The campground should be closely monitored for re-emergence of any purple loosestrife plants, particularly at site 14. Rollins Pond State Campground Invasive Plant Species: none observed Garlic mustard has been found at this campground as recently as 2014, so close monitoring should be conducted over future years to detect any re-emerging plants. Purple loosestrife has also been documented at the nearby Fish Creek Pond campground, so future monitoring should focus on the early detection and rapid response of this species. Saranac Lake Islands State Campground Invasive Plant Species: Not Inventoried This campground has never been surveyed for invasive plants because it is only accessible by boat. An initial inventory of this campground should be performed next year if resources are available to do so. Sharp Bridge State Campground Invasive Plant Species: purple loosestrife Locations: An infestation of purple loosestrife stretches along the rocky shoreline from the bridge at the campground entrance to the picnic area. A second patch is located on a sandbar downstream from the picnic area. The small island opposite the picnic area was also densely infested with purple loosestrife. 31

32 Ray Brook Working Circle 2015 A total of 677 purple loosestrife plants were removed from the campground this year. This campground should be monitored annually for purple loosestrife and for the introduction of new invasive plants. If time allows, a survey should be conducted to determine if the purple loosestrife infestation has colonized new areas downstream. Taylor Pond State Campground Invasive Plant Species: purple loosestrife Locations: Purple loosestrife was detected in two locations at this campground. The first site was found along the brick wall and boat rentals. The second site runs along both sides of a path originating between sites 20 and 21, leading to the water and extending a short distance down the shoreline. A total of 158 purple loosestrife plants were removed from the campground this year. This campground should be monitored annually in late summer for purple loosestrife and any other new invasive plant infestations. A construction area has been present at this campground the past two summers, occupying the dam at the end of the lake and the parking lot near the caretaker s cabin and boat launch. These areas should be checked more intensely in the future as new invasive plants could have been introduced through contaminated fill or spread by construction equipment. Wilmington Notch State Campground Invasive Plant Species: None observed This campground should be monitored annually for any new infestations of invasive plants. 32

33 Warrensburg Working Circle 2015 Warrensburg Working Circle Eagle Point Campground Invasive Plant Species: garlic mustard Locations: A small patch of garlic mustard rosettes was removed from alongside the drainage ditch behind site 66. A small patch of garlic mustard rosettes were pulled, but no second year plants were observed in This campground should be monitored annually to prevent the regrowth of the garlic mustard infestation. This infestation was discovered for the first time last year and with continued monitoring and management, presents a promising opportunity for eradication. This campground should also be monitored annually for purple loosestrife as it s located very close to the Lake Champlain Valley where purple loosestrife is rampant. Hearthstone Point State Campground Invasive Plant Species: garlic mustard, Japanese knotweed, Japanese barberry, bush honeysuckle Locations: Garlic mustard was found scattered throughout the campground at sites 58, 73, 189, 190, 219, 220, 238 and 239. Patches were also found across the road from site 88 and in the waste area behind sites 189 and 190. The patch in the spoils area is extremely large and dense. A large infestation of Japanese knotweed, within the waste area described above, surrounded the garlic mustard infestation. Japanese barberry and bush honeysuckle were also present at the campground, especially in the waste area. 33

34 Warrensburg Working Circle 2015 Approximately 3000 garlic mustard plants were removed from this campground, with the vast majority coming from the waste area. Complete management of this area was not possible due to the size of the infestation that was intermixed with the Japanese knotweed stand. 14 Japanese barberry plants were pulled and hung upside down in nearby trees to decompose, but many plants were left unmanaged due to time limitations. This campground should be monitored annually to manage the garlic mustard infestations at the campsites throughout the campground and to prevent any other invasive species from taking hold. Management of garlic mustard was completed with the aid of an SCA crew. If this resource is available in the future, it would be advisable to use a crew again to reduce the number of days needed to complete management. Many garlic mustard rosettes were observed, but not all were pulled; these plants will need to be removed next summer before they go to seed. Offering an invasive species identification and management seminar (focused on garlic mustard) for the staff here would be useful if time and resources are available. This would increase awareness among the staff about invasive plants, and their help could contribute to the success of future management efforts at this campground. The dense infestations of garlic mustard and Japanese knotweed located at the waste area should be managed in a less labor intensive way, perhaps through the use of herbicide. If time presents itself, after higher priority species are treated, the infestation of Japanese barberry could and should be managed. This species poses a health risk to campers due to its thorns and large infestations can provide excellent tick habitat. While managing this site, care should be taken, as ticks were found on some of the removed plants. Lake George Battleground Campground Invasive Plant Species: garlic mustard, Japanese knotweed, bush honeysuckle, Japanese barberry Locations: Garlic mustard was found and removed from sites: 7, 8, 10, 12, 14, 16, 17, 19, 20 and 42. There was also a patch found near the RV waste disposal area. A large patch was located behind sites 8-16 and extends onto private property behind a chain link fence. An infestation of Japanese knotweed exists toward the back of the garlic mustard infestation behind sites 8-16 and extends on to private land. Bush honeysuckle is present throughout the 34

35 Warrensburg Working Circle 2015 campground, but is especially prevalent in the area behind sites 8-16, with many large plants. Japanese barberry was found scattered throughout the campground, especially at the end of the road just past site 50. Approximately 5800 second year garlic mustard plants were pulled and removed from the campground, but full removalwas not completed due to the size of the infestation and due to the fact that part of the infestation extended onto private property. Approximately 19 Japanese barberry plants were pulled and hung upside down in nearby trees to decompose, but some were left unmanaged due to the size of the plants. This campground has one of the most extensive garlic mustard infestations of any of the state campgrounds monitored this year. Management of garlic mustard was undertaken with the aid of an SCA crew. If this resource is available in the future, it would be advisable to use a crew again to reduce the number of days needed to complete management. Many garlic mustard rosettes were observed, but not all were pulled; these plants will need to be removed next summer before they go to seed. Successful containment of this infestation will likely take multiple years of management. The owner of the private property that the infestations of garlic mustard and Japanese knotweed extend onto should be contacted to assist in the management of these infestations. Offering an invasive species identification and management seminar (focused on garlic mustard) for the staff here would be useful if time and resources are available. This would increase awareness among the staff about invasive plants, and their help could contribute to the success of future management efforts at this campground. The Japanese knotweed infestation should be monitored annually and treated with herbicide once appropriate landowner permission is attained. Any Japanese barberry plants found on the campground should be pulled if possible and hung upside down in nearby trees to dry and decompose. The bush honeysuckle infestation is large and fairly pervasive throughout the campground; it should only be managed if adequate time and resources are available after higher priority species have been managed. 35

36 Warrensburg Working Circle 2015 Lake George Islands Campground Invasive Plant Species: Not Inventoried This campground was not inventoried in 2015 due to the fact that the campsites are only accessible by boat. An inventory was conducted in 2007, revealing that purple loosestrife, bush honeysuckle, Japanese barberry, spotted knapweed, and multiflora rose were present at various campsites. Long Island was found to be infested with all five of these invasives, while Speaker Heck Island was only found to have bush honeysuckle, purple loosestrife, and spotted knapweed. Diamond Island contained only bush honeysuckle. These islands should be inventoried again and the invasive plants should be managed if resources and time are available to do so. These infestations were not managed when inventoried in 2007 and likely have not been managed since. Luzerne State Campground Invasive Plant Species: garlic mustard, bush honeysuckle Locations: Garlic mustard was found at site 4 this year. It was also found in the parking area and field adjacent to the shower house and among the bushes bordering the road in front of it. Three other patches were located along the main road into the campground just past the Field of Dreams. One of these is located at the start of a dirt road that cuts off from the main road, while another is located where the dirt road reconnects with the main road. The third is immediately after and opposite the Field of Dreams and extends down a hill from the roadside towards a stream. Honeysuckle grows prolifically along the roadsides when approaching and after passing the Field of Dreams. The infestations along the roadsides are composed of many very large bushes that would be nearly impossible to pull. A total of 310 second year garlic mustard plants were removed from the campground. This campground should be monitored annually to address the current garlic mustard infestation and to monitor for new introductions of invasive plants. Many garlic mustard rosettes were observed, but not all were pulled. These plants will need to be removed next summer before they 36

37 Warrensburg Working Circle 2015 go to seed. The honeysuckle infestation here should be cut and the stumps treated with herbicide, only if time and resources allow after other, higher priority invasive plant infestations have been managed. Rogers Rock State Campground Invasive Plant Species: garlic mustard, bush honeysuckle, Japanese barberry, winged burning bush Locations: Garlic mustard plants were found at sites: 4-9, 11, 17, 30, 32, 43, 55, 74-76, 82, 124, , 163, 165, 166A, 168, 169, 171 and 206. They were also found behind site 168 extending to the edge of State Rt. 9N. Japanese barberry and bush honeysuckle are also scattered in a few areas throughout the campground. Winged burning bush was found for the first time at this campground this year, at site 223. Approximately 1400 second year garlic mustard plants were removed from the campground. Most of these plants were removed from the densely infested area behind site 168. Three Japanese barberry plants were pulled and hung upside down in nearby trees to decompose. No management was completed on the bush honeysuckle or winged burning bush due to the size of the plants. This campground should be monitored annually to manage the garlic mustard infestation within the campground, as well as the infestation of Japanese barberry. Management of garlic mustard was completed with the aid of an SCA crew. If this resource is available in the future, it would be advisable to use a crew again to reduce the number of days needed to complete management. Many garlic mustard rosettes were observed, but not all were pulled. These plants will need to be removed next summer before they go to seed. Management of the winged burning bush should be undertaken in 2016 with a large stump puller or a cut stump treatment of herbicide if necessary. 37

38 Warrensburg Working Circle 2015 Scaroon Manor State Campground Invasive Plant Species: garlic mustard, winged burning bush, bush honeysuckle, Japanese barberry. Locations: Garlic mustard was found and removed from the slope behind site 58. Winged burning bush was present throughout the campground, a descendent of those planted as ornamentals at the resort located there in the 1940s. Bush honeysuckle and Japanese barberry also infest much of the campground. A total of 613 second year garlic mustard plants were removed from the campground this year. 31 Japanese barberry plants were pulled and hung upside down in nearby trees to decompose. This campground should be monitored annually for garlic mustard. It should also be monitored for other plants such as purple loosestrife, which infested the campground in If time and resources are available, management of the winged burning bush, bush honeysuckle, and Japanese barberry should take place, as these infestations extend far into the surrounding area. 38

39 Herkimer Working Circle 2015 Herkimer Working Circle Alger Island State Campground Invasive Plant Species: none observed This campground was inventoried this season for this first time since No invasive plants were detected. If time and access to a boat are available, this campground should be monitored annually to detect the introduction of any invasive species and facilitate rapid response. Garlic mustard is the primary species of concern, as it is established at numerous campgrounds in the immediate area. Nicks Lake State Campground Invasive Plant Species: garlic mustard, bush honeysuckle Locations: Garlic mustard is spread throughout this campground and is present at sites: 1-3, 5, 8-16, 18, 31, 43, 44, 50-52, 54-57, 59, 61, 65, 70, 72, 76, 82, 86, 103, 109 and 110. Patches were also found along the left side of the entry road to Loop A, around the air quality station, and across the road from site 98. Bush honeysuckle was found sporadically throughout the campground. A total of 1199 second year garlic mustard plants were pulled from the campground this year. This campground should be monitored annually to combat the current garlic mustard infestation and to prevent new honeysuckle bushes from taking hold. Management of the extensive garlic mustard infestation was completed with the aid of an SCA crew. If this resource is available in the future, it would be advisable to utilize the crew to reduce the number of days needed for management. Many garlic mustard rosettes were observed, but not all were pulled; these plants will need to be removed next summer before they go to seed. Offering an invasive species identification and management seminar (focused on garlic mustard) for the staff here would be useful if time and resources are available. This would increase awareness among the staff about invasive plants, and their help could contribute to the success of future management efforts. 39

40 Potsdam Working Circle 2015 Potsdam Working Circle Cranberry Lake Campground Invasive Plant Species: garlic mustard Locations: Garlic mustard was found and removed from sites: 2, 24, 37-39, 41, 50, 69, 80, 98, 100, 136, 141 and 149. A few patches of rosettes were also found at the waste disposal area. A total of 206 second year garlic mustard plants were pulled and removed from the campground this year. This campground should be monitored annually in order to combat the garlic mustard infestation. An enormous infestation was reported and managed in the waste area in 2014, but only rosettes were present this year. This area should be closely monitored in future years for returning plants. 40

41 Other Projects 2015 Adirondack Trailheads/Other DEC Locations Cascade/Porter (Essex County) Invasive Plant Species: garlic mustard This trailhead was managed for garlic mustard by the APIPP response team, who reported removing approximately 350 plants. Signage could potentially be installed at the trailhead to educate users about the current infestation and its effects, and to warn about other possible species that may be able to infest the trailhead and adjacent forest preserve. Giant Mountain via Roaring Brook (Essex County) Invasive Plant Species: none observed Locations: A single garlic mustard plant was observed and pulled at this trailhead in 2013, but no plants were detected in This trailhead should be continually monitored for garlic mustard, as it had been identified there in the past. The location should also be surveyed for other invasive plants, such as purple loosestrife, due to its close proximity to water. Giant Mountain Ridge Trail (Essex County) Invasive Plant Species: none observed This trailhead should only be monitored if there is extra time in the season. No invasive plants have been reported here, although others have been found in the area. 41

42 Other Projects 2015 Sargent Pond (Hamilton County) Invasive Plant Species: none observed Garlic mustard was observed and managed at this location in 2014, but none was observed this year. This trailhead should continue to be monitored on an annual basis to prevent the reestablishment of garlic mustard. Signage could potentially be installed at the trailhead to educate users about the current infestation and its effects, and to warn about other possible species that may be able to infest the trailhead and adjacent forest preserve. Blue Mountain (Hamilton County) Invasive Plant Species: none observed Garlic mustard was found at this location in 2014, but none was observed this year. This trailhead should continue to be monitored to prevent the reappearance of garlic mustard and to prevent its spread up the trail. Signage could potentially be installed at the trailhead to educate users about the current infestation and its effects, and to warn about other possible species that may be able to infest the trailhead and adjacent forest preserve. The Flume (Essex County) Invasive Plant Species: garlic mustard Due to time limitations, this trailhead was not assessed in A single garlic mustard plant was reported at this trailhead in 2014 to the right of the trailhead. This trailhead should be revisited in

43 Other Projects 2015 Grass River Wild Forest Lamson Falls Parcel (St. Lawrence County) Invasive Plant Species: garlic mustard Due to time constraints, this trailhead was not assessed in Garlic mustard was reported on imap Invasives and confirmed in The plants were located along the edge of the parking area. This trailhead should be monitored in 2016 to assess the current garlic mustard infestation. Upper Works (Essex County) Invasive Plant Species: garlic mustard, Japanese barberry Locations: Garlic mustard was found and removed from the edge of the parking lot which was located to the upper left as one drives towards the trail registration box. Japanese barberry was removed from the forest bordering the parking lot, just past the garlic mustard infestation. A total of 25 second year garlic mustard plants were removed from the trailhead this year. 6 Japanese barberry bushes were pulled and hung upside down in nearby trees to decompose, with a fourth being too large to manage. This trailhead should be continually monitored on an annual basis to combat the current infestation of garlic mustard and Japanese barberry and to prevent these species from spreading up the trail. Signage could potentially be installed at the trailhead to educate users about the current infestation and its effects, and to warn about other possible species that may be able to infest the trailhead and adjacent forest preserve. 43

44 Other Projects 2015 Alma Farm Park (near Tongue Mountain Wild Forest) (Warren County) Invasive Plant Species: garlic mustard Due to time constraints, this site was unmanaged in In 2014, garlic mustard was found and removed from the edge of the park and along State Rt. 9N on the right side of the road when driving south. This park should be prioritized for treatment in 2016 in order to combat the current garlic mustard infestation. It may be beneficial to check the trailhead parking areas nearby which access the Tongue Mountain Wild Forest, as there may be garlic mustard present there. Aldrich Pond Wild Forest access road (St. Lawrence County) Invasive Plant Species: garlic mustard Locations: Garlic mustard was removed from campsite 13. APIPP staff managed this site in 2015 and reported pulling approximately 10 second year garlic mustard plants. Campsite 13 should continue to be monitored on an annual basis to see if garlic mustard is still growing there. Monitoring for other invasive plants, such as purple loosestrife, should be considered as well because there are swampy areas along the access road and Streeter Lake is located at the end of the road. 44

45 Other Projects 2015 Sawyer Mountain (Hamilton County) Invasive Plant Species: purple loosestrife Due to time constraints, this location was not managed this season. A single purple loosestrife plant was found and removed from the edge of the parking area in This trailhead should be assessed in 2016 to determine if purple loosestrife is still present. Parking Area to access Lake Durant (Hamilton County) Invasive Plant Species: purple loosestrife Locations: Purple loosestrife was found in the grassy area between the parking area and the road. A single plant was removed from this site in This parking area should continue to be managed to reduce the purple loosestrife population. Good Luck Lake/Dexter Lake (Hamilton County) Invasive Plant Species: wild parsnip Locations: Wild parsnip was found bordering the parking lot and extending a short distance down either side of the road. A total of 28 wild parsnip plants were pulled from the trailhead and parking area in

46 Other Projects 2015 This trailhead should continue to be monitored for returning wild parsnip plants, as Route 10 has been documented to have several large infestations. The plants should be removed from the areas bordering the parking lot and trailhead due to the potential health hazards presented by this plant s toxic sap. Care should be taken to avoid exposure to the sap while undertaking management. Jockeybush Lake (Hamilton County) Invasive Plant Species: wild parsnip Locations: Wild parsnip plants were removed from either side of the road around the trailhead parking area. The infestation continued on the other side of the road onto private property. A total of 8 wild parsnip plants were removed. The infestation could not be completely managed due to its expansion onto private property. The trailhead should continue to be monitored to prevent the reintroduction of wild parsnip onto the side of the road that the trailhead is on. Any plants that spread from the infestation on private property should be removed due to the health hazard posed by this plant s toxic sap. Care should be taken to avoid contact with the sap while undertaking management. Piseco Outlet Access Point (Hamilton County) Invasive Plant Species: wild parsnip Locations: Wild parsnip was found surrounding the parking lot for the Piseco Lake Outlet access area. The infestation continued down a private dirt road. A total of 9 wild parsnip plants were removed from the parking area, but full management was not possible due to the infestations expansion onto private property. 46

47 Other Projects 2015 This area should be continually monitored and managed for wild parsnip. Any returning plants in the parking area should be removed due to the health hazard posed by this plant s otoxic sap. Care should be taken to avoid coming into contact with this sap during management. Squaw Lake (Hamilton County) Invasive Plant Species: garlic mustard Locations: Garlic mustard plants were found along the entry road to the parking area for this trailhead. A total of 5 second year garlic mustard plants were removed from this site. This infestation should be monitored annually for returning garlic mustard. The small size of this infestation allows for the possibility of eradication with continued management. 47
