The preserve includes 2 miles (3.2 km) of walking trails, which cross wetlands and ridge top.[1] There are also 180 species of trees, shrubs and wildflowers. It is managed by the Louisville Nature Center, which is located on the west side of the preserve in a building which opened in 1997. The center claims it is "one of the largest inner-city nature preserves" in the United States.[2] The preserve and nature center run on about a $90,000 annual budget, and in May 2007 reported about $100,000 in operational debt.[3]
