Additional wetland and upland points were taken to confirm the continuing boundary of the resource to the northeast. Overall, the resource was delineated based on a lack of wetland hydrology and hydrophytic vegetation at upland sample points 4B and 4D forming a gradual to moderate transition boundary in most areas. Upland vegetation communities are generally dominated by black willow, boxelder, Kentucky blue grass, smooth brome, Canada goldenrod (Solidago altissima) and ground ivy (Glechoma hederacea). ATYPICAL/PROBLEMATIC CONDITIONS Analysis of antecedent precipitation revealed that the area was well above average at the time of the field investigation, surface hydrology was observed in several areas. CONSISTENCY WITH DESKTOP REVIEW NWI inventoried areas were found to be generally correct; however, additional wetland was found in hydric soil units. 1 Appendix B contains wetland determination data forms supporting this investigated resource: Wet Point(s): 4A, 4C Up Point(s): 4B, 4D 2 Appendix E contains MnRAM output 270
