Red threeawn,sand <br /> dropseed and several other early perennials can dominate the plant community for five to eight years or more.Eventually western <br /> wheatgrass,blue grama and other natives can become reestablished.Prescribed grazing can accelerate the successional process. <br /> Reference Community <br /> This is the interpretive plant community and is considered to be the Reference Plant Community.This plant community evolved with grazing <br /> by large herbivores and is well suited for grazing by domestic livestock and can be found on areas that are properly managed with prescribed <br /> grazing that allows for adequate recovery periods following each grazing event. <br /> The plant community consists of 70-85%grasses and grass-likes,5-10%forbs and 10-20%shrubs.Dominant grasses include alkali sacaton <br /> and western wheatgrass.Blue grama,sideoats grama and Galleta are secondary grasses.Other grasses and grass-like plants that occur in <br /> minor amounts are green needlegrass,little bluestem, Indian ricegrass and sun sedge.Significant forbs are American vetch,leafy false <br /> goldenweed and scarlet globemallow.Dominant shrubs that occupy this community are fourwing saltbush,winterfat,shadescale saltbush and <br /> James'frankenia. <br /> This plant community is diverse,stable,and productive. It is well suited to carbon sequestration,water yield,wildlife and livestock use and is <br /> esthetically pleasing.Community dynamics,nutrient cycle,water cycle and energy flow are functioning properly.Plant litter is properly <br /> distributed with very little movement off-site and natural plant mortality is very low.This community is resistant to many disturbances except <br /> continuous grazing,tillage and/or development into urban or other uses. <br /> Total annual production,during an average year,ranges from 250 to 1000 pounds per acre air-dry weight and will average 600 pounds. <br /> NOTE:The following Reference Plant Community Species Composition list and Annual Production Table is from the Legacy ESD 2004 and <br /> will be updated in the future. <br /> Reference Community Plant Species Composition <br /> Grass/Grasslike Annual Production <br /> (p.Qundsggr acrt<). <br /> Group Group name Common name Symbol Scientific name LOW High <br /> 1 525 675 <br /> Grass,perennial 2GP 5 20 <br /> Indian ricegrass ACHY Achnatherum hymenoides 0 10 <br /> Fendler threeawn ARPUL Aristida pyrpurea var.longiseta 0 5 <br /> sideoats grama BOCU Bouteloua curtipendula 60 120 <br /> buffalograss BODA2 Bouteloua dactyloides 0 5 <br /> blue grama BOGR2 Bouteloua gn2golir,2 90 120 <br /> sun sedge CAINH2 Carex inops subsp.heliophila 0 5 <br /> saltgrass DISP Distichlis s ica a 0 10 <br /> squirreltail ELELE Elymus elymoides subsp. 0 5 <br /> ptym i <br /> needle and thread HECOC8 Hesoerostipa comata subsp 0 10 <br /> comata <br /> prairie Junegrass KOMA Koeleha macrentha 0 5 <br /> ring muhly MUT02 Muhlenbergia torrey-i 0 5 <br /> green needlegrass NAVI4 Nessella vindu/a 20 40 <br /> vine mesquite PAOB Panicum obtusum 0 5 <br /> western wheatgrass PASM Pascopyrum smith ii 90 150 <br /> James'galleta PLJA P/euraphis j m ii 60 90 <br /> tumblegrass SCPA Schedonnardus paniculatus 0 5 <br /> alkali sacaton SPAI Sporobolus airoides 150 210 <br /> sand dropseed SPCR Snorobolus crypanLruii 0 5 <br /> Forb Annual Production <br /> (pounds per acre) <br /> https://esis.sc.egov.usda.gov/ESDReport/fsReportPrt.aspx?id=R069XY046CO&rptLevel=all&approved=yes&repType=regular&scrns=&comm= 6/16 <br />
