Overall,the majority of land within the survey has been used <br /> for agriculture (mainly livestock) and may be somewhat overgrazed and/or degraded. Topography across <br /> upland habitats is relatively flat throughout a majority of the survey area. A summary of upland habitat <br /> within the survey area is provided as follows. <br /> Inter-Mountain Basins Montane Sagebrush Steppe <br /> This vegetation community occupies the majority of the survey area and includes lands that are currently <br /> used for horse pasture, as much of this community is fragmented by fences for rotational grazing. In <br /> general, this community exhibits more shrub species and more established herbaceous vegetation along <br /> the southern and western portions, due to it not being used as pasture in recent time. The central and <br /> northern portions of the community have been subject to heavy grazing and represents a more degraded <br /> form of this vegetation community.Vegetation across this community is dominated by small (typically less <br /> than 2 feet in height) shrub species such as big sagebrush and rubber rabbitbrush (Ericamerio nauseosa) <br /> intermixed with a herbaceous understory dominated by species such as rocky mountain fescue (Festuca <br /> saximontona), mountain brome(Bromus morginatus),common yarrow(Achillea millefolium),and varileaf <br /> cinquefoil (Potentilla diversifolia) comprising approximately 50%-60% ground cover with the remaining <br /> ground cover comprised of exposed surface soil and rock.The western extents of this upland community <br /> within the survey area comprise the shoulder slope and partially down the slope to the riparian corridor <br /> of the Blue River.This shoulder slope/hillslope area is entirely uplands with a similar vegetation community, <br /> however, exhibits overstory canopy tree cover of Engelmann spruce (Picea engelmannii) and narrowleaf <br /> cottonwood (Populus angustifolia),with sparse shrub cover of species such as woods' rose(Rosa woodsii), <br /> intermixed with smaller percentages of the species described above. Soils within this community are silt <br /> loam to loam textured,dry,loamy,and light colored underlain by larger rock.An upland ditch exists within <br /> 1/20/21 10 <br />
