Warren County

Weiler-Leopold Nature Reserve

Situated along the Wabash River in eastern Warren County, the reserve features open oak savannas, wooded slopes, old fields dotted with boulders deposited by glaciers and a wonderful space to connect with nature. Among the natural area are 100+ acres of bottom-lands planted with trees in May of 2000 returned to native forest habitat, and a 12-acre grassland area restored to native tall grass prairie.

Beginning near the parking lot, two loop trails meander through the prairie, down the slope, through the savanna and loop back up the slope and return to the prairie.

History of Acquisition and Property

Weiler-Leopold Nature Preserve refers to the renowned former owners, two families with strong ties to conservation and land management.  The family of Emanuel Weiler, founding dean of Purdue’s School of Management and the Krannert Graduate School once owned a section of the property. The family of A. Carl Leopold, an internationally known plant physiologist and son of the renowned naturalist Aldo Leopold also owned a section of the land.  Acquired in 1999 with the support of the Indiana Heritage Trust, the Roy Whistler Foundation, the Sycamore Audubon Society, the Weiler, Leopold, and Sanna families, and nearly two hundred additional individuals, families, groups,and businesses, Weiler-Leopold holds place among the earliest owned by NICHES Land Trust.  The acreage includes rich biodiversity and a collection of native habitats including prairie and oak savanna.

The Nature Preserve sits adjacent to the later acquired NICHES property Black Rock Barrens, and Birdfoot Barrens Nature Preserve, making a combined 300 acres of protected habitat.

“All ethics so far evolved rest upon a single premise: that the individual is a member of a community of interdependent parts. The land ethic simply enlarges the boundaries of the community to include soils, waters, plants and animals, or collectively the land.” The Land Ethic (1949) by Aldo Leopold
