Yes ✓ No (If no,explain in Remarks.) <br /> Are Vegetation Soil ,or Hydrology significantly disturbed? No Are"Normal Circumstances"present? Yes ✓ No <br /> Are Vegetation Soil ,or Hydrology naturally problematic? No (If needed,explain any answers in Remarks.) <br /> SUMMARY OF FINDINGS— Attach site map showing sampling point locations,transects, important features,etc. <br /> Hydrophytic Vegetation Present? Yes No <br /> Is the Sampled Area <br /> Hydric Soil Present? Yes No �/ <br /> within a Wetland? Yes No <br /> Wetland Hydrology Present? Yes No <br /> Remarks: <br /> Wetland data point in a low point in the central portion of the survey area that appears to have been previously flooded seasonally.The soils had a <br /> significant amount of clay,which appeared to assist in retaining water near the surface as compared with the surrounding uplands.This data point is <br /> paired with upland data point DP-C1a. <br /> VEGETATION—Use scientific names of plants. <br /> Absolute Dominant Indicator Dominance Test worksheet: <br /> Tree Stratum (Plot size. ) %Cover Species?
