R065XY026Co•-Sandy Plans tRU's A&B:Reference Plant Community—Eli:atCounty, <br /> Colorado.Eastern Part <br /> R069XY026C0 — Sandy Plains LRU's A & B: <br /> Reference Plant Community <br /> Plant Community Description <br /> This is the interpretive plant community.This plant community evolved with <br /> grazing by large herbivores,is well suited for grazing by domestic livestock,and <br /> can be found on areas that are properly managed with grazing that allows <br /> adequate recovery periods following each grazing occurrence during the growing <br /> season. <br /> The potential vegetation is about 7D-85%grasses and grass-like plants. 10-15% <br /> forbs and 5-15%woody plants.The dominant tall warm season grasses are <br /> prairie sandreed,sand bluestem and switchgrass, Blue grama dominates the <br /> understory. Important cool season grasses and grass-likes are needleandthread, <br /> western wheatgrass and sun sedge_Key forts and shrubs are American vetch, <br /> purple prairie clover,western sandcherry and fourwirlg saltbush. <br /> This plant community is characteristic of the Western Great Plains and is <br /> resistant to many disturbances except prolonged continuous grazing, sodbusting, <br /> urban and other development.The diversity in plant species allows for high <br /> drought tolerance. Plant litter is properly distributed with very little movement off- <br /> site and natural plant mortality is very low.This is a sustainable plant community <br /> in terms of soil stability,watershed function and biologic integrity. <br /> Production in this community can vary from 800 to 2100 pounds of air-dry <br /> vegetation per acre per year depending on weather conditions and averages <br /> 1500 pounds. <br /> NOTE:The following Reference Plant Community Species Composition list and <br /> Annual Production Table is from the Legacy ESD 2004 and will be updated in the <br /> future. <br /> Plant Community Tables <br /> (c) Estimate of site plant production for rangelands: <br /> Rare Type Low Representative vague High <br /> asslice 700 1,180 1.565 <br /> for) 170 190 218 <br /> ShruhMine 8u 150 217 <br /> TGWU 950 1,500 2,000 <br /> rl.5tri Natural Rexourcas We Sol Survey 11123t2017 <br /> Conservation Service National Cooperative Soil Survey Page 1 M t <br /> 66 <br />
