Trott Brook North Property, Ramsey Wetland Delineation Report Conservation Service (NRCS) in cooperation with the National Technical Committee for Hydric Soils, Version 8.1, 2017). Mapped soils are separated into five classes based on the composition of hydric components and the Hydric Rating by Map Unit color classes utilized on Web Soil Survey. The five classes include Hydric (100 percent hydric components), Predominantly Hydric (66 to 99 percent hydric components), Partially Hydric (33 to 65 percent hydric components), Predominantly Non-Hydric (1 to 32 percent hydric components), and Non-Hydric (less than one percent hydric components). Plants were identified using standard regional plant keys. Taxonomy and indicator status of plant species was taken from the 2018 National Wetland Plant List (U.S. Army Corps of Engineers 2018. National Wetland Plant List, version 3.3, Engineer Research and Development Center, Cold Regions Research and Engineering Laboratory, Hanover, NH). 4. RESULTS 4.1 Review of NWI, Soils, Public Waters, and NHD Information The National Wetlands Inventory (NWI) (Minnesota Geospatial Commons 2009-2014 and U.S. Fish and Wildlife Service) showed two PEM1Af wetlands, one PEM1C/PFOIA/PEM1A wetland, one PEM 1 Ad/PABG wetland and one R2UBFx/PFO 1 A/d/PEM 1 Cd/PSS 1 A/PABG wetland complex within site boundaries (Figure 3). The Soil Survey (USDA NRCS 2015) showed Blomford, Brickton, Isan-Isan, Marsh, and Rifle as the mapped hydric soil types within site boundaries. Soil types mapped on the property are listed in Table 2 and a map showing soil types is included in Figure 4. Table 2. Soil types mapped on the Trott Brook North site.
