The Avon Bottoms Wildlife Area is a tract of protected land located on the border of Illinois in Rock County, Wisconsin, managed by the Wisconsin Department of Natural Resources (WDNR).

[1] The Avon Bottoms Wildlife area was established in 1960 as part of a federal wildlife restoration project, specifically to improve duck and pheasant populations in the area to attract hunters.

[2] The area was established to improve and preserve wildlife and habitat diversity along the Sugar River, a popular destination for kayakers, canoers, and tubers.

[5] The Natural Resources Conservation Service, an agency of the United States Department of Agriculture restored wetlands and grasslands in the area, with 3,100 such acres working as easements directly adjacent to the wildlife area.

The 1986 WDNR master plan for the Wildlife Area states that some of these trees are near record size, and important to the biodiversity and the environment.
