Paige “Vegetation structure and animal species richness (variety and number) were generally lower in grazed than ungrazed communities.” “Leopold (1974) suggested that we have seriously under-estimated the impact of grazing on the capacity of wild lands to support native animal populations” “Direct results of grazing include removal of vegetative cover and trampling of grass and brush” “Indirect or delayed results of grazing include altered forage composition, reduced vigor or plants, and accelerated soil erosion resulting in a reduction of land productivity.” “Long term effects of heavy grazing often result in vegetative changes toward more xeric conditions.” http://md1.csa.com/partners/viewrecord.php? Livestock Grazing Platts, WS Influences of Forest and Rangeland Management on Salmonid Fishes and Their Habitats. pp. 389-423. American Fisheries Society Special Publication [Am. Fish. Soc. Special Pub.]. no. 19. Historical management practices have allowed streamside environments to deteriorate. Decision makers now generally accept the need to improve the management of these streamside areas. In addition, scientists are now studying livestock-fishery interactions and developing good data banks. Before progress can be made in improving the management of riparian areas, however, riparian environments must first be accepted as discrete management units and receive specialized, site-specific consideration. Ordinary allotment management, based primarily on the needs of livestock, originated in the early 1960s and will no longer suffice unless the allotments are further broken down into their respective habitat types. Livestock grazing can affect all components of the aquatic system. Grazing can affect the
