RULE 2 PERMITS Productivity, as determined by the BIM, is .25 AUM's per acre for the aspen type in this area indicating that the condition of the mountain shrub community within the permit area is good. As previously stated, the deep, loamy soils and high soil moisture conditions together with the generally northern aspect combine to provide the required conditions for the aspen community. Where soil moisture becomes less plant available earlier into the summer, elements of the mountain shrub community begin to dominate. Generally,this occurs due to a change in aspect of the topography or shallower soil depth. For further details on soil/moisture relationships in determining the aspen vegetation community refer to Figure 2.04.10-1, Environmental Gradient/Plant Tolerance Graph. Riparian Community Within the permit area the riparian community is very limited. The community is confined to areas along Good Spring Creek and Taylor Creek. The community is characterized by a very limited overstory of a few isolated cottonwoods (Populus angustifolia),and boxelder trees(Aver negundo).Understory vegetation includes Wood's rose (Rosa woodsii), willows (Salix spp.), rushes (Juncus spp.), sedges (Carex spp.), and cattails (Typha spp.). The riparian community is found along the drainage bottoms where soil moisture is abundant throughout the growing season. Soil texture ranges from fine clay to coarse, sandy loam soils. Elements of the sagebrush and mountain shrub communities are soon encountered adjacent to the riparian community where plant available moisture begins to decrease. For further details on Soil/Moisture relationships in determining the riparian vegetation community refer to Figure 2.04.10-1, Environmental Gradient/Plant Tolerance Graph. Grassland Community Within the permit area,the grassland community covers a very limited area. Small,isolated patches of almost exclusively western wheatgrass growing on heavy clay soils are scattered in the middle elevations of the southern part of the permit area. The community is of such limited extend(+/- 30 acres) that only mention of occurrence is contained here. Cropland Within the north end of the permit area a few areas of cropland are encountered at the southern edge of Axial Basin. The previous landowners removed the sagebrush and cultivated the land for winter wheat production. The soils are primarily a clay loam texture on a flat to rolling topography. The area surrounding the croplands incorporates elements of the sagebrush community encountered throughout the rest of the permit area.
