UPDATED NATURAL RESOURCES INVENTORY FOR <br />SOUTH OF DIVIDE STUDY AREA <br />• ~ The species in this table area indicative of riparian areas, also. <br />Riparian areas do not have as formal a definition as wetlands. Riparian areas are typically defined <br />as areas along streams and rivers dominated by plants adapted to higher moisture conditions. <br />WWE met with the USFS staff (Michael Wazd, Barry Johnston, and Andrea Wang in August <br />1995; Barry Johnston in September 2004) to create a working definition of riparian areas for this <br />inventory. Based on these meetings, riparian areas have been defined as: (1) all wetlands and (2) <br />other areas dominated by key riparian "indicator species." Key indicator riparian species include <br />the species listed in Tables 1 and 2. <br />TABLE 2 <br />Riparian Indicator Species' <br />• <br />Stratum Common Scientific Name <br />Trees Box elder Negundo aceroides <br /> Mountain maple Acerglabrum <br /> Narrowleaf cottonwood Populus angustifolia <br /> Blue spruce Picea pungens <br />Shrubs Willows Salix spp. <br /> Hawthorn Crataegus erythropoda <br /> Redtwig dogwood Suida sericea <br /> Wild rose Rosa woodsii <br />Grasses/Forbs Western coneflower Rudbeckia occidentalis <br /> Cow parsnip Heracleum lanatum <br /> Sedges Carex spp. <br /> Rushes Juncus spp., Scirpus spp. <br /> Stinging nettles Urtica dioica <br />' Riparian areas may also include the species listed in Table 1. <br />• <br />Aspen is more prevalent in the eastern portion of the study area. Engleman spruce (Picea <br />engelmannri), subalpine fir, lodge pole pine, and aspen occur at the highest portions of the site in <br />the southeast corner of the study area. <br />631-032.690 Wright Water Engineers, Inc.
