, COLORADO LIVESTOCK GRAZING MANAGEMENT GUIDELINES N to (7) ~ 1. Grazing managemant practices promote plant health by providing for ona or more of the following: . periodic rest or deferment from grazing during critical growth periods; . adequate recovery and regrowth periods; . opportunity for seed dissemination and seedling establishment. 2. Grazing management practices address the kind, numbers, and class of livestock, season, duration, distribution, frequency and intensity of grazing use and livestock .health. 3. Grazing management practices maintain sufficient residual vegetation o.n both upland and riparian sites to protect the soli from wind and water erosion, and buffer temperature extremes. In riparian areas, vegetation dissipates energy, captures sediment, recharges ground water, and contributes to. stream stability. 4. Native plant Sipecies and natural revegetation are emphasized in the support of sustaining ecological functions and site integrity. Where reseeding is required, on land treatment efforts, emphasis will bEl placed on using native plant species. Seeding of non-native plant species will be . considered based on local goals, native seed availability and cost, persistence of non-native plants and annuals and noxious weeds on the site, and composition of non-natives in the seed mix; 5. Range improvement projects are designed consistent with overall ecological functions and processes with minimum adverse impaCtS to other resources or uses of riparian/wetlandand.upland sites. 6. Grazing management will occur in a manner that does not encourage the establishment or spread of noxious weed.s. In addition to mechanical, chemical, and biological methods of weed control, livestock may be used where feasible as a tool to inhibit or stop the spread of noxious.weeds. 7. Natural occurrences such as fire, drought, flooding, and prescribed land treatments should be combined with livestock management practices to move toward the sustainabllity of biological diversity across the landscape by helping to provide natural vegetation .patterns,a mosaic of successional stages, and vegetation corridors, thus minimizing habitat fragmentation. , '.,' , 8.
