12/9/2019 ESD Printable Report <br /> 1. Number and extent of rills:None on gentle slopes,slight on steeper slopes. <br /> 2. Presence of water flow patterns:None to minimal on gentle slopes(<15%).Flow paths should be broken,irregular in appearance. <br /> As slope steepness increases,flow paths become more apparent and may be connected. <br /> 3. Number and height of erosional pedestals or terracettes: None to slight on gentle slopes.Expect some evidence of pedestalled <br /> plants when slopes exceed 15%. <br /> 4. Bare ground from Ecological Site Description or other studies(rock,litter,standing dead,lichen,moss,plant canopy are not <br /> bare ground):5%or less bare ground,with bare patches generally less than 3 inches.Extended drought may increase bare ground 5- <br /> 10%. <br /> 5. Number of gullies and erosion associated with gullies: None <br /> 6. Extent of wind scoured,blowouts and/or depositional areas: None to slight.Minor wind scouring may occur on steep ridges.Wind <br /> erosion can occur with disturbances such as wildfire or extended drought. <br /> 7. Amount of litter movement(describe size and distance expected to travel):Litter movement is associated with water flow patterns <br /> and may move as much as 1-3 feet or more down slope during severe precipitation events,especially on steeper slopes. <br /> 8. Soil surface(top few mm)resistance to erosion(stability values are averages-most sites will show a range of values): <br /> Stability class rating anticipated to be 3-4 in interspaces at soil surface.These values need verification. <br /> 9. Soil surface structure and SOM content(include type and strength of structure,and A-horizon color and thickness):Average <br /> SOM ranges from 1-3%.Soils are dominantly very shallow to shallow and well drained.A-horizon color is light brownish-gray with a <br /> weak fine crumb structure.Exposed sandstone bedrock is inherent to the site. <br /> 10. Effect on plant community composition(relative proportion of different functional groups)and spatial distribution on <br /> infiltration and runoff: Diverse grass,forb,shrub functional/structural groups and diverse root structure reduces raindrop impact slows <br /> overland flow providing increased time for infiltration to occur.However,the composition of the plant community has less affect on <br /> infiltration and runoff than does slope and the amount of exposed sandstone. <br /> 11. Presence and thickness of compaction layer(usually none;describe soil profile features which may be mistaken for <br /> compaction on this site):None <br /> 12. Functional/Structural Groups(list in order of descending dominance by above-ground weight using symbols:>>,>,=to <br /> indicate much greater than,greater than,and equal to)with dominants and subdominants and'others"on separate lines: <br /> Dominant:warm season mid bunchgrass> <br /> Sub-dominant:warm season tall bunchgrass=warm season short bunchgrass>shrubs>Cool season mid bunchgrass>warm <br /> season tall rhizomatous=cool season mid rhizomatous=leguminous forbs=other forbs> <br /> Other:warm season mid sod-former=sedges>short trees <br /> Additional: <br /> 13. Amount of plant mortality and decadence(include which functional groups are expected to show mortality or decadence): <br /> None to slight.Decadence may exist on areas inaccessible to grazing animals. <br /> 14. Average percent litter cover(40-50%)and depth(0.25inches): Litter cover during and following extended drought can range from <br /> 20-30%. <br /> 15. Expected annual production(this is TOTAL above-ground production,not just forage production):600 lbs./ac.low precipitation <br /> years; 1000 lbs./ac.average precipitation years; 1600 lbs./ac.high precipitation years.After extended drought or the first growing <br /> season following wildfire,production may be significantly reduced by 250-500 lbs./ac. <br /> https://esis.sc.egov.usda.gov/ESDReport/fsReportPrt.aspx?id=R069XY053CO&rptLevel=all&approved=yes&repType=regular&scrns=&comm= 18/19 <br />
