intensive herbicide management to control its spread. (See also recommendation in preceding discussion on forested wetland.) The wetland area immediately down -slope from the construction site (4bf /3b) has been drained by a ditch system at its outlet. Recommendation: Restoration of this area could be easily accomplished by back - filling the drainage ditch. Off to the right of the entrance drive within the Town Center facility, there is a depressional wetland that has become invaded by ash, boxelder, American and red elm, with reed canary grass beginning to invade the understory. Native species that have persisted include mad -dog skullcap (Scutellaria lateriflora), lake sedge (Carex lacustris), wood nettle (Boehmeria cyl nnddrica ), Joe -pye weeds ( Eupatorium perfollatum, Eupatorium rugosum), and a few others. This site has also been de- watered by woody vegetation encroachment into the historic wetland muck and peat soils. Recommendation: With brushing and fire re- introduction, this area potentially could become a sedge - dominated wetland, a magnificent front -drop to the office facility. The site also historically was surrounded by oak savanna remnants, which still occur. These could be managed like the other degraded oak savannas to the overall improvement of the site. A small wetland area adjacent to a new out -fall structure adjacent to the new Town Center building has a major element of native sedges and a large population of reed canary grass. The reed canary grass element should be disfavored through direct herbicide management and prescribed burning. Recommendation: This little area associated with storm water out -fall could be managed for water quality enhancement. This could be achieved by planting additional native wetland species, such as river and soft stem bulrushes (Scirpus fluviatilis, S. validus), irises, and others. These species can tolerate some of the water quality impacts associated with run off from uplands, while beautifying the area.
