Show 2. Phreatophyte removal and control along streams, drainage of wetlands, and stream channel improvements reduce riparian vegetation and, in some cases, may affect esthetics and the wildlife resource base, 3. Alteration of particular types of native vegetation is some- times necessary for treatment of land for increased livestock forage, erosion and sediment control, and increased water yield. This tends to be detrimental to some wildlife species while benefiting others. k. Reservoirs may occupy reaches of potential wild, scenic, and recreation rivers, and parts of designated or potential wilderness areas. It will be necessary to study and determine the need for reaches of streams to be designated as wild and scenic rivers. 5. Reservoirs, as well as many other improvements, could inundate or obliterate archeologic, cultural, or historic sites. These sites contain the key to the heritage of the past and their loss would be irretrievable. 6. Developments such as highways, transmission lines, and urban development alter the natural environment and tend to reduce the resource base of the Region. 7. Despite advances in antipollution design and technology, thermal electric power plants cause some pollution of the environment and the growing antipathy toward such plants may become a deterrent to installation. 8. Competition among uses of available water will be one of the strongest conflicts in years ahead, particularly in the absence of adequate regional water supply augmentation. Implementation of all programs requiring a water supply would be difficult and, in some cases, impossible. 9. Urban expansion is predicted to encroach on prime agricul- tural land. Irrigated agriculture may be forced to develop less suitable land in order to maintain a stable agricultural- economy. 10. Fish and wildlife interests have indicated that large acre- ages of land need to be managed primarily for wildlife. Other interests have indicated that some of these same areas need to be managed on a multiuse basis which may conflict with primary fish and wildlife uses. 115 |
