Yes No <br /> %Bare Ground in Herb Stratum 0% <br /> Remarks: <br /> Even though the vegetation community meets the dominance test for hydrophytic vegetation;it is mostly because of the presence of Baltic Rush <br /> (FACW)which does not seem to be a good indicator in this area given that it was observed growing in conjunction with FACU-UPL species and in <br /> wetlands.Further,underlying hydric soils and/or wetland hydrology are not present.Meets the criteria for hydrophytic vegetation. <br /> US Army Corps of Engineers Western Mountains,Valleys,and Coast—Version 2.0 <br />
