12/9/2019 ESD Printable Report <br /> 3. Number and height of erosional pedestals or terracettes: None <br /> 4. Bare ground from Ecological Site Description or other studies(rock,litter,standing dead,lichen,moss,plant canopy are not <br /> bare ground):5-7%or less bare ground,with bare patches generally less than 2-3 inches in diameter.Extended drought can cause <br /> bare ground to increase upwards to 15-25%with bare patches reaching upwards to 12-18 inches in diameter. <br /> 5. Number of gullies and erosion associated with gullies: None <br /> 6. Extent of wind scoured,blowouts and/or depositional areas: None <br /> 7. Amount of litter movement(describe size and distance expected to travel): Minimal and short. <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 5-6 in interspace at soil surface.These values need verification at reference site. <br /> 9. Soil surface structure and SOM content(include type and strength of structure,and A-horizon color and thickness):Average <br /> SOM is 1-3%.Soils are typically deep to moderately deep,light brownish-gray to light olive-brown,weak very thin platy to weak fine <br /> granular structure,approximately 0-4 inches in depth. <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.Extended drought reduces short/mid bunchgrasses causing decreased <br /> infiltration and increased runoff following intense storms. <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 sub-dominants and'others"on separate lines: <br /> Dominant:cool season mid rhizomatous>warm season short bunchgrass> <br /> Sub-dominant:shrubs=warm season mid rhizomatous>cool season mid bunchgrass> <br /> Other:warm season forbs>leguminous(orbs>cool season forbs=warm season mid bunchgrass>warm season short <br /> stoleniferous>grasslike>annual native grasses <br /> Additional: <br /> 13. Amount of plant nicrrtality and decadence(include which functional groups are expected to show mortality or decadence): <br /> Typically minimal.Expect short/mid bunchgrass mortality/decadence during and following drought. <br /> 14. Average percent litter cover(25-35%)and depth(.25inches): Litter cover during and following extended drought ranges from 10- <br /> 20%. <br /> 15. Expected annual production(this is TOTAL above-ground production,not just forage production):300 lbs./ac.low precipitation <br /> years;750 lbs./ac.average precipitation years; 1100 lbs./ac.above average precipitation years.After extended drought or the first <br /> growing season following wildfire,production may be significantly reduced by 100—250 lbs./ac. <br /> 16. Potential invasive(including noxious)species(native and non-native).List Species which BOTH characterize degraded states <br /> and have the potential to become a dominant or co-dominant species on the ecological site if their future establishment and <br /> growth is not actively controlled by management interventions.Species that become dominant for only one to several years <br /> (e.g.,short-term response to drought or wildfire)are not invasive plants.Note that unlike other indicator,we are describing <br /> what is NOT expected in the reference state for the ecological site: Invasive plants should not occur in reference plant community. <br /> Cheatgrass,Russian thistle,kochia,other non-native annuals may invade following extended drought or fire if a seed source is <br /> available.Oneseed juniper may infrequently invade from adjacent sites with lack of fire. <br /> 17. Perennial plant reproductive capability:The only limitations are weather related,wildfire,and natural disease that may temporarily <br /> reduce reproductive capability. <br /> https://esis.sc.egov.usda.gov/ESDReport/fsReportPrt.aspx?id=R069XY042CO&rptLevel=all&approved=yes&repType=regular&scrns=&comm= 15/16 <br />
