YesXNo <br />Are Vegetation,Soil,or Hydrologynaturally problematic?(If needed, explain any answers in Remarks.) <br />SUMMARY OF FINDINGS –Attachsite map showing sampling point locations, transects, important features, etc. <br />Hydrophytic VegetationPresent?YesNoX <br />Hydric Soil Present?YesNoXIs the Sampled Area within a Wetland? YesNoX <br />Wetland Hydrology Present?YesNoX <br />Remarks: Located on riprap bank on outside of riverbend. Local slope is 5%,landward the slope is ~40%. Surface is an intermediate floodplain <br />surface. Soils are disturbed from presence of riprap justbeneath the surface. <br />VEGETATION –Use scientific names of plants. <br />Dominance Test worksheet: <br />Absolute DominantIndicator <br />Tree Stratum(Plot size:15’)% CoverSpecies?Status <br />Number of Dominant Species <br />That Are OBL, FACW, or FAC:1(A) <br />1.30yFACU <br />Acer macrophyllum <br />Total Number of Dominant <br />2. <br />Species Across All Strata:2(B) <br />3. <br />Percent of Dominant Species <br />4. <br />That Are OBL, FACW, or FAC:50%(A/B) <br />30= Total Cover <br />Prevalence Index worksheet: <br />Sapling/Shrub Stratum(Plot size:10’) <br />Total % Cover of:Multiply by: <br />1.5yFAC <br />Rubus armeniacus <br />OBL species0x 1 = <br />2. <br />0 <br />3. <br />FACW speciesx 2 = <br />4. <br />FAC species5x 3 =15 <br />5. <br />FACU species30x4=120 <br />5= Total Cover <br />UPL species0x 5 =0 <br />Herb Stratum (Plot size:5’ r) <br />Column Totals:35(A) 135(B) <br />1.5y <br />Poa spp <br />Prevalence Index = B/A =3.9 <br />2. <br />3. <br />Hydrophytic Vegetation Indicators: <br />4. <br />5. <br />1-Rapid Test for Hydrophytic Vegetation <br />6. <br />2-Dominance Test is >50% <br />7. <br />3-1 <br />8. <br />4-Morphological Adaptations 1(Providesupporting <br />data in Remarks or on a separatesheet) <br />9. <br />5-Wetland Non-Vascular Plants <br />1 <br />10. <br />Problematic Hydrophytic Vegetation(Explain) <br />1 <br />11. <br />5= Total Cover <br />Indicators of hydric soil and wetland hydrology must <br />1 <br />be present, unless disturbed or problematic. <br />Woody Vine Stratum(Plot size:) <br />1. <br />2. <br />Hydrophytic <br />= Total Cover <br />Vegetation <br />% Bare Ground in HerbStratum95 <br />Present?YesNox <br />Remarks: <br />Riprap prominentin this areaat and just beneath the surface. <br />US Army Corps of Engineers Western Mountains, Valleys, and Coast –Version 2.0 <br />
