The significant nature preserve in the Black Creek Watershed is the Bergen Swamp.  It is a landmark well known across America.  Glacial scour about 10,000 years ago during the latest Ice Age, formed a depression in the bedrock where the Bergen Swamp presently is situated.  In 1964, The Bergen Swamp was among the first sites in the United States to receive the distinguished designation of Natural History Landmark by the U. S. Department of the Interior.

The swamp has over 2,500 species of plants, including many rare flora and fauna.  The small white Lady Slipper is the Bergen Swamp poster plant.  Among the rare plants are orchids, and the pitcher plant, which devours insects.  Northern plants such as twinflower, clintonia, bunchberry, hobblebush, cotton grass, goldthread, one flowered pyrole, mountain aster, and stiff club moss are all found in the Bergen Swamp.

Bergen Swamp now a private nature preserve in the Towns of Bergen and Byron in Genesee County.  It is managed by the Bergen Swamp Preservation Society (BSPS).

The Genesee Land Trust owns the Brookdale Preserve and the Reed Road Preserve (131 acres).

The New York Natural Heritage Program - New York State Department of Environmental Conservation recognizes 2,797 acres within the Black Creek watershed as wetlands or swamp areas.
