Fens stay wet year-round and can remain in the same location for thousands of years.



Why is this Preserve Significant?

Where land and water come together, wonderful things happen. Wet, spring-fed fens blends into floodplain forest to create the globally significant habitat known as Ives Road Fen Preserve! Fens are unusual, and increasingly rare. The water from this fen flows through the thick grasses of the preserve, which help to filter the water before it empties into the River Raisin at the preserve's eastern edge. The River Raisin is one of the best warm water rivers in the state, and three of the four local communities downstream draw all of their drinking water from this river.

What can I see here?

A fine chorus of spring peepers can be heard calling in March. The splendor of wildflowers and prairie grasses can be enjoyed from June to August. Catch beautiful formations of migratory birds as they arrive in the spring and leave in the fall. The fen is home for many rare plants such as the carnivorous sundew and the showy coneflower.

Historically, most of the land in this preserve had been impacted by human activity including agriculture, sand and gravel mining, and drainage ditches. However, thanks to thousands of volunteer hours by local community members over the last two decades, this preserve is now largely restored to its natural state.




The biggest battle against invasive species at Ives Road Fen Preserve has been waged against glossy buckthorn. In the two decades since buckthorn removal efforts began, Conservancy staff and volunteers have removed more than 2.5 million adult buckthorn stems, spot burned 10 million buckthorn seedlings, and burned nearly 400 brush piles of adult buckthorn shrubs. In 2010, we celebrated the removal of the last populations of adult glossy buckthorn from the preserve, a monumental milestone.

Be aware of poison ivy, poison sumac, chiggers and stinging nettle at this site. Because of the wet and uneven ground conditions, wear waterproof boots with ankle support.

The Nature Conservancy allows hunting for white-tail deer on this preserve to reduce an unnaturally high deer population in the area and reduce threats too many deer pose to our conservation targets. All hunters are required to receive a permit from the Conservancy as well as a Michigan deer hunting license. Additionally, hunters must report any deer taken from the preserve.

Permitted Activities:

  • Foot access for hiking, snowshoeing, bird watching, etc.
  • Educational Studies
  • Geocaching
  • Hunting for white-tail deer with Conservancy permit

Prohibited Activities:

  • No motorized and non-motorized vehicles, including but not limited to automobiles, off-road vehicles (ORVs), all-terrain vehicles (ATVs), motorcycles, snowmobiles, amphibious vehicles, and bicycles. All visitors must park at the gate and walk in.

Ives Road Fen Preserve has a long history of exceptional volunteer involvement. In the years following the creation of this preserve in 1987, The Nature Conservancy initiated recurring volunteer work days to control invasive glossy buckthorn. In 1997, a Volunteer Conservation Committee was formed under the extraordinary leadership of Chuck Pearson, who had led hundreds of volunteer days over the years. Chuck and the group of dedicated volunteers began weekly work days from April through November.

Then, on November 13, 2010, the last stand of adult glossy buckthorn was removed from this preserve, expanding the restored fen from five acres to almost 100 acres! This was a tremendous achievement, which would never have happened without the hard work of Chuck Pearson and the many members of the Volunteer Conservation Committee.

With the buckthorn removed, volunteers have turned their attention to other invasive plants such as autumn olive, honeysuckle, garlic mustard and dame’s rocket. They have also begun restoring the native prairie and surveying populations of the native massasauga rattlesnake. The Conservancy is deeply grateful for this group of dedicated volunteers and the thousands of hours they contribute to make Ives Road Fen such a beautiful, natural place.

Join Us for Volunteer Work Days at Ives Road Fen Preserve

Saturdays: April, May, September, October
Time: 8:50 a.m.-12:00 p.m.
Location: 4997 N. Raisin Center Hwy, Tecumseh, Michigan 49286

Throughout the spring and fall, you will enjoy seeing butterflies and various bird species. In the spring months, we pull garlic mustard in the floodplain forest next to the River Raisin and enjoy the spring woodland wildflowers and some herptiles. In fall, we cut honeysuckle in the upland area near the prairie and enjoy the fall colors and fall fruits. Workdays include cold drinks and fresh chocolate chip cookies. As a volunteer, you will get a chance to see parts of the preserve that most visitors never get to see.
