Nature Preserve Area:
Location and Access:
From the Intersection of US 51 and a county road at the north end of Tonica, take the county road east 0.5 mile until the road angles to the northeast. Follow this road 1.25 mile to a county road. Turn north on this road and go 1.75 mile. The preserve is on the east side of the road.
This nature preserve contains young forest, bluffs and streams typical of sites near the Vermilion River in the Grand Prairie Section. Some excellent examples of eroding bluff plant communities may be seen here. Over seventy-five species of flowering herbaceous plants have been identified in the preserve including forked aster and bottle gentian. Deer, beaver and red fox are also known to inhabit the area.
This preserve is named in memory of Margery Carlson, who was instrumental in protecting the area, formerly known as Big Bend Nature Preserve. Carlson was a founder of the Illinois chapter of The Nature Conservancy, serving the chapter as its first secretary and later as trustee.
