Prairie fens provide habitat for both wetland and prairie plants, making them especially diverse and important to the preserve.



It's no coincidence that the Paw Paw River watershed is also known as Michigan's "Wine Country." The temperate climate, fertile soil and nearby river create idyllic conditions not only for vineyards, but also for land rich in biodiversity.

Notice the migration of songbirds during the fall months. You are most likely to catch them on their way south during August and September. Those with patience might spot species such as the eastern box turtle or an eastern massasauga rattlesnake. 



No pets are permitted.


This land will be open for foot access and activities such as hiking, snowshoeing, birdwatching and deer hunting by permit.

Rare Wetland Communities

The Paw Paw Prairie Fen site was originally slated for a housing development. The development company had removed all the topsoil, laid out a road route and began landscaping for a neighborhood when TNC was alerted to rare wetland communities at the site and began negotiations for acquiring the land.

A fen is a unique type of wetland, fed by alkaline, mineral-rich groundwater that supports highly diverse and rare plant life. There are several types of fens, but prairie fens, like Paw Paw Prairie Fen, provide habitat for both wetland and prairie plants, making them especially diverse and important to the preserve.

Frequently Asked Questions

  • The Paw Paw Prairie Fen Preserve is open year round for hiking, birding and wildlife viewing. August and September are the best times to catch sight of migrating songbirds on their way south.

  • Because of wet and uneven ground conditions during much of the year, we recommend wearing waterproof boots with ankle support. Also be sure to check for ticks after hiking as prairie grasses provide them with prime habitat.

  • The 1.5-mile loop trail is generally considered an easy route, with wide, flat, well-packed terrain.

TNC owns 106 acres along the east branch of the Paw Paw River near Mattawan. Fen restoration began in 2004 with the removal of invasives including glossy buckthorn and reed canary grass.

The following year, efforts to restore the native savanna began by treating invasives such as spotted knapweed and replanting prairie grass seed of varieties native to this habitat at this location. We have removed four acres of full-grown spruce trees, which were planted to line the main avenue of the housing development.

Professional land managers also employ prescribed fire throughout the preserve to reduce invasive species and promote healthy habitats for native plants and animals. These restoration strategies continue to be implemented throughout the preserve.

The Nature Conservancy has teamed up with farmers, the Van Buren Conservation District, The Coca-Cola Foundation and Michigan State University to protect and improve water quality and quantity in the Paw Paw River watershed.
