Show characteristic of the major plant communities is found in Attachment A, Tables 1 through 9. Additional information concerning the flora of the proposed Bonneville Unit area is contained in the report prepared for the Bureau of Reclamation by the Center of Health and Environmental Studies, Brigham Young University entitled " Preliminary Survey of the Biota of the Bonneville Unit of the Central Utah Project" o66 Pertinent information concerning selected sites has been extracted from the report and is presneted below. Specific Locations ( 1) Upper Stillwater Reservoir Site This area along Rock Creek constitutes one of the few remaining subalpine spruce- fir communities on the south slope of the Uinta Mountains in which the vegetation is largely undisturbed by man. The only evidence of use are recreation trails along the stream, around campgrounds and leading into the mountains. There are also signs of grazing by domestic livestock„ ( 2) Lower Stillwater Reservoir Site This area has received moderate use by man. However, only a few introduced species of plant are found and in general the various plant communities are thriving in good condition. ( 3) Currant Creek Reservoir Site Disturbance of the native plant cover in this area has been minimal. Few exotics are present. The wet meadow- strearnside willow community is in excellent condition. ( 4) Strawberry Reservoir Enlargement The presettlement vegetation of this area was dominated by grasses with some wet meadows or marshlands. As land development progressed changes in vegetative patterns occurred so that 20 years ago shrubs such as sagebrush Were conspicuous in the drier locations and willows were abundant along the streams. However, a large part of the enlargement site has been sprayed with herbicides and the abundance of woody plants has been greatly decreased. This spraying program has resulted in much of the area being dominated by grasses similar to original conditions. 126 |
