1 CAPS/SLAM: Salt Marsh Assessment Inner Marsh Version May 2012 Vegetation Site Form Site ID (Bin-Index): Site Name/Town: Bank condition (for length of plot): Bank vegetation (for length of plot): Comments: Plot Diagram Sketch a diagram of the sample plot. Include the following sampling information: baseline length (in meters); transect IDs; transect lengths (in meters); location of origin sample point; and locations of macroinvertebrate sampling stations if they are flagged for future sampling. Also, sketch marsh features, including creeks, marsh zones/dominant plant communities, and invasive species in and around the plot. In addition to the plot diagram, sketch the location of the sample point and all transects on the Site Map (aerial photo).

2 Vegetation Form: Site ID Transect ID Record the transect number, lat/long, length, compass bearing (circle M for magnetic north or T for true north), distance from sample point, and point interval. Walk along the transect and record the presence of plants touching the bayonet at each interval. Use the table below to mark a tic in each cell for intervals 1 11 where a plant is present. Use the blank cells at the end of the table to record the genus and species for plants not listed. Additional plant species are listed on the next page.

4 Habitat Complexity Form: Site ID Transect ID After completing the Vegetation Form, walk back along the transect towards the water feature. Use the tape measure to observe and record the locations (distance in meters) and types of habitat transitions along the transect. Do not record transitions for habitats that measure less than one meter along the transect. Habitats are defined as heterogeneous plant communities (e.g. Spartina patens / Distchlis spicata mix) and hydrogeomorphic features (e.g., panne, pool, and creek, plus ditch) associated with the marsh. Both a plant community and hydrogeomorphic feature can be recorded at the same location (e.g. Spartina alterniflora-short and panne). Record the tape measure reading for each habitat transition to the nearest tenth of a meter in the appropriate box(s) (e.g. 5.5 m). Separate recorded habitat transitions with a comma if that habitat occurs more than once on a transect. List no more than three plant species when describing a community. Record species in order of dominance, with the first species being the most dominant. For example, record a habitat patch that includes S. patens (75%), J. gerardii (25%), and P. maritimum (< 1%) as S. patens / J. gerardii mix. Record start and end distances (range) for all hydrogeomorphic features (e.g. Panne = m). Include patches and features that are offset up to 1 m from the transect. Complete a Habitat Complexity Form for each transect. See the next page for a marsh zonation reference diagram (Figure 1). Distichlis spicata Juncus gerardii Plant Community Transition Distance (m) Hydrogeomorphic Feature Transition Distance (m) Spartina alterniflora-short Spartina alterniflora-tall Spartina patens S. alterniflora-short / S. patens mix S. patens / S. alterniflora-short mix S. patens / D. spicata mix S. patens / J. gerardii mix D. spicata / S. patens mix MARSH DIEBACK Creek Ditch Panne Pool

This diagram shows the major plant zones and dominant species; see text for details and Tiner (1987), Mitsch and Gosselink (1993), or Bertness (1999) for a description of salt marsh vegetation patterns. (Adapted from Carlisle, et al, 2002).

6 Human Disturbance Form: Site ID Walk the perimeter of the sample plot and describe in the table below the types, extents, and severity of disturbances within a 100 m buffer of the sample point (200 m diameter circle depicted on the site map). Disturbance types are listed below. Use the bracketed letters preceding each disturbance type to mark locations of disturbances on the provided site map. Also record any of these indicators of disturbance when encountered while implementing other elements of the SOP. [A] Water control structures (culvert, tide gate, dam, weir, storm water input, fill (road/railroad), ditching, channelization, and other human activity affecting the hydrology of the site [B] Soil disturbance (filling, sedimentation, haying) [C] Obvious spills [D] Direct point or non-point source discharge from agricultural operations, septic or sewage treatment systems, or storm water affecting water quality of the site [E] Walking trails, horse trails, and roads (excluding wildlife trails) [F] Small-craft boating (presence of docks, moorings, or observed boating) and boat storage [G] Presence of trash/litter [H] Presence of garbage dumping Type Presence Description of type, areal extent, and severity of impact
