Trelease Woods and Buffer

A 24.5 ha (60.5 acres) (plus 10.7 acre prairie buffer) "virgin" deciduous upland forest. Primarily a mature oak/ash/maple forest with a high, closed canopy and moderately dense understory. Sugar maple has rapidly become the dominant tree species. The woods is a remnant of a much larger prairie grove which was present at Euro-American settlement times (ca. 1820) and was originally connected with Brownfield Woods. The Woods is relatively flat, poorly drained, with a mostly undisturbed soil history. There are two, small, man-made seasonal ponds, one within the woods and one on the south edge of the woods. Buffer land on the north and northeast sides of the woods are 50 m in depth and were seeded to alfalfa and mixed prairie species in 2002 (4.3 ha/10.7 acres). Trelease Prairie runs up to the south edge of the woods. A system of marked grid posts, at 50 meter intervals, is in place. Located about 3 miles NE of the UIUC campus. Fenced. Vehicle access around the perimeter of the woods. Agricultural land abuts on three sides of the woods with Phillips Tract across the road on the west side. Acquired in 1917-1918.

Location: The west 1/2 of the SW 1/4 of section 1, Urbana township, Champaign Co. The 911 address is 1710 N. Cottonwood Rd. About 3 miles NE of Urbana. On the east side of Cottonwood Rd. across from the Phillips Tract site.
