Yes Vill 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 /> Hydric Soil Present? Yes No ✓ Is the Sampled Area <br /> Wetland Hydrology Present? Yes No v/ within a Wetland? Yes No <br /> Remarks. <br /> Upland data point located in horse pasture Data point does exhibit a dominance of hydrophytic vegetation,however,is considered upland because underlying hydric sod are not present Pair with wetland data point DP-A5a <br /> VEGETATION—Use scientific names of plants. <br /> Absolute Dominant Indicator Dominance Test worksheet: <br /> Tree Stratum (Plot size: ) %Cover Soecies?
