12/9/2019 ESD Printable Report <br /> Increased Inland Saltgrass, Decreased MidfTall Grasses(At Risk)Plant Community: <br /> The wildlife found in the Reference Plant Community are expected in this plant community.The reduction in mid and tall grasses and the <br /> increase in shorter species may attract mountain plover,horned lark,long-billed curlew,and black-tailed jackrabbit. <br /> Inland Saltgrass Sod With/Without Western Wheatgrass,With/Without Alkali Sacaton Plant Community;Decadent Plants,Excessive Litter <br /> Plant Community;and Foxtail Barley,Annuals,Bare Ground Plant Community: <br /> The reduction of shrubs and taller grasses in these plant communities results in a shift of bird species away from the Reference Plant <br /> Community birds.Cassin's and Brewer's sparrow stop using the community altogether.Use by species such as mountain plover,horned <br /> lark,and long-billed curlew would increase.Mammals,reptiles,and amphibians from the Reference Plant Community may continue to use <br /> these communities. <br /> Altered Hydrology Plant Community(DRAFT):Will resembled a Salt Flat site.(RESERVED) <br /> GRAZING INTERPRETATIONS: <br /> The following table lists suggested initial stocking rates for an animal unit(1000 pound beef cow)under continuous grazing(year long <br /> grazing or growing season long grazing)based on normal growing conditions.However,continuous grazing is not recommended.These <br /> estimates should only be used as preliminary guidelines in the initial stages of the conservation planning process.Often,the existing plant <br /> composition does not entirely match any particular plant community described in this ecological site description.Therefore,field inventories <br /> are always recommended to document plant composition,total production,and palatable forage production.Carrying capacity estimates <br /> that reflect on-site conditions should be calculated using field inventories. <br /> If the following production estimates are used,they should be adjusted based on animal kind/class and on the specific palatability of the <br /> forage plants in the various plant community descriptions.Under a properly stocked,properly applied,prescribed grazing management <br /> system that provides adequate recovery periods following each grazing event,improved harvest efficiencies will eventually result in <br /> increased carrying capacity.See USDA-NRCS Colorado Prescribed Grazing Standard and Specification Guide(528). <br /> The stocking rate calculations are based on the total annual forage production in a normal year multiplied by 25%harvest efficiency divided <br /> by 912.5 pounds of ingested air-dry vegetation for an animal unit per month. <br /> Plant Community
