- ; The dfflinffwM wetland boundary followed a change in plant communities and topography. Wetland 1 corresponded to an NWI-mapped PUBF wetland, and an area of mapped hydric soil (Glencoe) by the soil survey. An outlet on the west side of the wetland drained Wetland 1 off site to the south/southwest. WeOaHd i was a Type 3 (PUBG/PEMF/aA/PSSlC) wetland that encompassed the majority of the southern half of the site. Dominant vegetation consisted of cattail, reed canary grass, sedge, American elm and green ash with lesser amounts of willow, giant goldenrod, conunon reed, cttnging nettle, clearweed, sedge and red osier dogwood. Two transect locations were sampled for Wetland 2. The following is a description of Transect 2-1. Soils observed below the wetland boundary were mapped as Marsh and were black muck to 14 inches, underlain by distinctly mottled, dark gray sandy clay to 24+ inches. Soils were saturated at the surface and free water was observed at 10 inches below the soil surface. Secondary indicators of hydrology included mapped hydric soils, the FAC-Neutral Test and topographic position. Adjacent upland for Transect 2-1 was woods dominated by red oak, bur oak, common buckthorn, honeysuckle, basswood and northern udiite cedar with lesser amounts of cherry American cottonwo^ qiiftking aspen, meadow rue, geranium, pq)er birch, prickly ash, walnut, eastern red cedar, spruce, eastern white pine and hackberry. Upland soils were mapped as Kilkenny and were black clay loam to 24 inches. No primary or secondaiy indicators of hydrology were observed. Upland vegetation varied along the boundary of WeUand 2 and included areas of open me^ow Hotniniif»»H by Canada goldenrod, orchardgrass, Kentucky bluegrass and smooth brome with lesser of quackgrass, reed canary grass, creeping Charlie and sumac, an area along the southern tip dominated by common buckthorn, garlic mustard and other weedy species, and an area toward the nordieast dominated by northern udiite cedar with lesser amounts of common buckthorn, sumac, Kentucky bluegrass and Canada goldenrod. The dflinffl**^ wetland boundary followed a change in plant communities and topography. Wetland 2 corresponded to NWI-mapped PEMF and R2UBH weUands, and an area of mapped hydric soil (Marsh) by the soil survey. A wide channel bisects the wetland and drains into Tanager Lake to the southeast. WettmiS was a Type 3 (PEMF/C/A) wetland located along the roadside ditch in the northeast comer of the site. Dominant vegetation consisted of cattail, duckweed, reed canary grass and green ash with lesser amounts of jewelweed, stinging nettle, common buckthorn and sedge. Soils observed below the wetland boundary were mapped as Glencoe and were black mucky loam to 12 inches, underlain by very dark gray fine sandy clay loam with common medium gray redox depletions to 24+ inches. Soils were inundated to a depth of 6 inches at the sample location. Secondary indicators of hydrology included mapped hydric soil, the FAC-Neutral Test and topographic position. Adjacent iqrland was woods dominated by sugar iiuq)le and bur oak with lesser amounts of tMirthem white cedar, coirunon buckthorn, cherry, green ash, American basswood, Virginia creeper, paper birch and walnut Upland soils were mqiped as Kilkermy and were black
