Fish Creek, a high-quality stream home to several species of important fish and mussels, runs through Douglas Woods. The Nature Conservancy has operated an office since 1992 in Angola to help protect this important waterway. Fish Creek is a medium sized, warm water headwater stream leading to the St. Joseph River. Fish Creek drains an agricultural watershed that is 110 square miles and contains the most diverse assemblage of fresh water mussels in the Great Lakes Basin. In all 31 species of mussel inhabit the creek, three of which are federally endangered, along with 43 species of fish. Fish Creek supports the last known population of the White Cat’s Paw Pearly mussel in the world.

What the Nature Conservancy is Doing/has Done
Much of the tillable land is leased to a local farmer willing to practice conservation tillage to demonstrate to area farmers how to reduce soil loss and chemical runoff without sacrificing productivity or profits. The remainder of the old farmland is being reforested to increase habitat for woodland birds and other wildlife.

Within the forest, control efforts are ongoing to eradicate garlic mustard from the site.
