1997 by Powder River Eagle Studies, Inc.(PRES) The scope of that study was developed in <br />consultation with local and regional CDOW personnel. The supplemental information for the extension • <br />area is contained in Section 11 .2 of Tab 11. <br />Areas Covered by Studies <br />The early wildlife studies (1974 and 1979) were conducted on a lease area that included the 1980 <br />Seneca II -W Permit Area and extended south to include portions of the Seneca II -W South Extension <br />area. To provide a direct correlation between the permit and study areas, the original 1980 permit area <br />0 974 and 1979 wildlife study areas) was designated as the wildlife study area and clearly outlined on <br />all maps, even though the actual wildlife studies extended beyond the designated study area <br />boundaries. Wildlife occurrence and usage of both the 1980 permit area and those portions of the <br />actual extended study area to the south are similar as habitat types within both areas coincide. <br />Wildlife studies were also conducted in 1979 in an area designated for construction of the Tie -Across <br />Haul Road which would allow SCC to move coal from Routt County Road 53 to the Hayden Power <br />Station. The original proposed location of the haul road was changed at the request of the CDOW to <br />avoid disturbing habitat areas utilized by sandhill cranes. • <br />In 1997, supplemental wildlife studies were conducted in an area immediately south of the original <br />1980 Seneca II -W Permit Area, designated as the Seneca II -W South Extension area. Wildlife studies <br />for the II -W South Extension area are presented in Section 11.2. <br />Habitat Designations <br />Habitat type designations used for wildlife resource evaluations generally parallel the vegetation <br />community classifications described in Tab 10. In the early wildlife studies, a separate forb habitat <br />type was delineated and described. This type is characterized by very limited areal extent and is <br />interspersed among the Western wheatgrass/alkali sagebrush vegetation community, from which it was <br />not differentiated during vegetation studies. Because forb habitat was utilized by many wildlife species <br />during the spring and early summer periods, however, it was sampled separately during the original <br />wildlife baseline studies. <br />Revised 9/98 <br />
