The Shirley Heinze Land Trust, originally known as the Shirley Heinze Environmental Fund, is a 501(c)(3) nonprofit land trust dedicated to the preservation of natural areas in Northwest Indiana. The Heinze Trust manages more than 2,800 acres of protected land in Lake, Porter, LaPorte, St. Joseph, Starke, and Marshall Counties in Indiana.[1] Its preserves include a wide range of dune, wetland, prairie, and forest ecosystems.
Due to the heavily developed nature of the Calumet Region, many of the Heinze Trust's parcels are entirely surrounded by industrial or residential development. Many of the preserves were severely degraded when first acquired, and the Heinze Trust has engaged in a wide range of restoration activities in order to restore them to ecological viability.[2] The Heinze Trust's preserves include six designated Indiana Nature Preserves,[1] some of which were purchased with funds from the Indiana Heritage Trust.[3]
