6 Because of the great variety and complexity of the plant communities occurring within 7 the six states, the area is best represented by description at the ecoregion level. The 22 Level III 8 ecoregions covering the six-state area include a wide variety of upland plant community types, 9 such as coniferous forest, coniferous and deciduous woodland, shrub communities, shrub steppe,
10and grassland. Numerous basins occur in the study area and often support shrublands, such as
11Great Basin sagebrush, saltbush-greasewood, creosotebush, or palo verde-cactus shrublands.
12Basins in the region are typically arid and include the Chihuahuan, Mojave, and Sonoran
13Deserts. Habitats on plateaus may include woodland, shrubland, or grassland. Shrublands and
14pinyon-juniper woodlands are common in the Colorado Plateaus ecoregion. The basins and
15plateaus of the study area include the predominance of those areas where solar energy
16development is most likely to occur.
17
18Wetlands occurring within these ecoregions are extremely varied. While surface flows
19provide the water source for some wetlands, other wetlands are supported by groundwater
20discharge. Wetlands are often associated with perennial water sources, such as springs, perennial
21segments of streams, or lakes and ponds. However, some wetlands have seasonal or intermittent
22sources of water. Riparian vegetation communities occur along rivers, perennial and intermittent
23streams, lakes, and reservoirs, and at springs. These communities generally form a vegetation
24zone along the margin that is distinct from the adjacent upland area. Riparian communities are
25dependent on streamflows or reservoir levels and are strongly influenced by the hydrologic
26regime.

32 4.10.2 Wildlife
33
34Section 4.10.2 of the Draft Solar PEIS discussed the wildlife management objectives of
35the BLM and other agencies in the six-state study area. The section also described the wildlife
36species (amphibians, reptiles, birds, and mammals) that may occur on BLM lands where solar
37energy development could occur (special status wildlife species were discussed in Section 4.10.4
38of the Draft Solar PEIS). The section included information on the number of wildlife species
39reported for each of the states and on the species hunted or trapped within the six-state study
40area. The regulatory framework to protect migratory birds, bald and golden eagles, and greater
41sage-grouse was also described. General life history information and state conservation status
42ranks were provided for the big game species. The information provided in Section 4.10.2 of the
43Draft Solar PEIS remains valid.
