UTM 11 473241E 3820312N (WGS84/NAD83) USGS VICTORVILLE Quad 1 Grid and Magnetic North Declination Arrow Vertical black line w/ star on top = Geographic True North indicator. Blue G arrow is the Grid declination [the amount the UTM grid differs from geographic North at this location] Universal Transverse Mercator (UTM) projection = "straight up" on the UTM map. The blue value below the map, labeled "G =" is the value of the Grid declination in degrees. The blue arrow points in the direction of UTM Grid North. The red M arrow = Magnetic declination. This is the amount True North differs from magnetic North at this location right now. The red value below the map, labeled "M =" is the value of the Magnetic declination in degrees. The red arrow points in the direction of magnetic North. 1 Adapted from http://www.topozone.com/map.asp?z=11&n=3820312&e=473241&s=50&size=l&datum=nad83&layer=drg25

Where the Wild Things Live2 Objective: Provided with a basic map of the campus, students will locate, map and identify, using a simple key, the various plant communities/habitats present on the Mojave River Campus (MRC). Introduction: All of the organisms that you ll observe in the Wildlands are adapted to particular set of living conditions, or plant community/habitat. Some organisms are able to live within one plant community/habitat year-round. Some species find it necessary to switch plant community/habitats at different times of day or year due local or regional environmental changes. Some migratory organisms, in fact have to switch regions and even continents to find conditions suitable for their survival. The Mojave River Wildlands (MRW) includes several diverse plant community/habitat within one ecosystem (desert-riparian). Habitats can be described in different ways. To tell them apart you ll use plant communities and the existence of water. There are many different plant communities in the MRW. For the purpose of this lesson you ll classify or group the plant community types 3 into 3 main habitat groupings (based on available water) and 11 specific habitats (based on the plants supported). Terrestrial Habitats 1. Urban (developed) 2. Rocky cliffs, outcrops, and boulder fields (Boulder and Rock Field) MOJAVE DESERT SCRUB HABITAT 3. Saltbrush Scrubland (Desert Saltbush Scrub [Atriplex spp.] ) 4. Mojave Desert Scrub (Creosote Bush Scrub [Larrea tridentata], (Saltbush - Creosote Bush 5. Disturbed Scrubland [Larrea tridentata-atriplex polycarpa]) RIPARIAN AND BOTTOMLAND HABITAT 6. Cottonwood-willow forest (Fremont Cottonwood Riparian Woodland [Populus fremontii] Mojave Riparian) Wetland Habitats MEADOWS and SEEPS HABITAT 7. Wet Meadow 8. Seep MARSH HABITAT 9. Marsh Bulrush - Cattail Wetland [Scirpus spp.-typha spp.]) Aquatic Habitats 10. Pond (Lacustrine) 11. River (Riverine) Mapping Habitats: On the map of the MRC Wildlands provided, sketch the major plant community/habitat boundaries and indicate using a key/legend and color code the basic habitat types. 2 Adapted from http://www.halton-borough.gov.uk/naturereserves/educationalactivities.asp 3 From http://www.dfg.ca.gov/whdab/pdfs/natcomlist.pdf
