Rth 7BYO24Co-•Sandy plains:Reference kw Community--Elbert County.Cdatattu, <br /> Eastern Part <br /> R067BY024C0 — Sandy Plains: <br /> Reference Plant Community <br /> Plant Community Description <br /> This is the interpretive plant community and is considered to be the Reference <br /> Plant Community.This plant community evolved with grazing by large herbivores, <br /> and is well suited for grazing by domestic livestock. It can be found on areas that <br /> are properly managed with prescribed grazing that allows for adequate recovery <br /> periods following each grazing event. The potential vegetation is about 70-85% <br /> grasses and grass-like plants, 10-15%fortrs,and 5-15%woody plants, <br /> The dominant tall warm season grasses are prairie sandreed, sand bluestem and <br /> switchgrass.Blue grana dominates the understory_ Important cool season <br /> grasses and grass-likes are needle and thread and sun sedge. Key forbs and <br /> shrubs are American vetch.pacific peavine(manystem pea),purple prairie <br /> clover,and spreading buckwheat. <br /> This plant community is diverse,and productive.Litter is properly distributed with <br /> very little movement off-site,and natural plant mortality is very low.It is welt- <br /> suited to carbo,sequestration.effective water cycle,and wildlife use by many <br /> species,livestock use,and is aesthetically pleasing. Community dynamics, <br /> nutrient cycle, water cycle,and energy flow are functioning property.This <br /> community is resistant to disturbances except moderate to heavy continuous <br /> grazing,tillage, and/or development into urban or other uses. <br /> Total annual production ranges from 800 to 2.200 pounds of air-dry vegetation <br /> per acre and will average 1.650 pounds during an average year.These <br /> production figures are the fluctuations expected during favorable,normal and <br /> unfavorable years due to the timing and amount of precipitation and temperature. <br /> Total annual production should not be confused with species productivity,which <br /> is annual production and variability by species throughout the extent of the <br /> community phase. <br /> Plant Community Tables <br /> (c) Estimate of site plant production for rangelands: <br /> --- Type Low aMp�Mftne Value HighKara <br /> G:asstGrasslike 900 1,300 r 1.690 <br /> Fort 150 2o0i 255 <br /> Shn.,hArinr, 50 150 255 <br /> Totals 600. _...... 1.650 2,200 <br /> Liu M.Wrai Resources Web Solt Survey 1(5Z513017 <br /> Conservation Service Natineat Cooperative Soil Survey Page 1 or 4 <br /> 73 <br />
