Places We Protect

Erie Marsh Preserve


Erie Marsh represents 11% of the remaining marshland in southeastern Michigan and is one of the largest marshes on Lake Erie.

Why Is This Preserve Significant?

Located on North Maumee Bay, Erie Marsh Preserve supports numerous animals and plants that would otherwise be hard-pressed to find suitable habitat. This sprawling preserve plays a huge role as a migratory and nesting area for shorebirds, waterfowl, landbirds and, in the fall, raptors.

In 2011, TNC implemented a multi-year project to restore 946 acres of highly degraded coastal wetlands at Erie Marsh. The project goals are to allow the exchange of water and energy and movement of animals between the preserve and Lake Erie; provide access to key spawning areas for fish species; control invasive species (most notably, Phragmites); and improve the overall quality of the wetland to benefit the plants and animals that live here. 

What Can I See Here?

No matter the time of year, Erie Marsh Preserve is a birding hotspot. As you walk along the pathways dividing the different wetland areas, you are likely to see a number of ducks, shorebirds, songbirds, or a great egret, great blue heron or black-crowned night heron. Every spring and fall, Erie Marsh serves as important nesting and stopover habitat for thousands of migratory birds to rest and feed. In the fall, bald eagles commonly breed here. At more than 2,200 acres, the preserve also harbors some of Michigan’s few remaining colonies of American lotus, and swamp rose-mallow, both listed as state-threatened, as well as the threatened eastern fox snake.


Be advised that while the preserve is open, a multi-year wetland construction and restoration project is underway. During your visit, you may encounter areas of the preserve that are closed off to the public for safety reasons. We appreciate your understanding and cooperation while we work to restore one of the largest remaining coastal wetlands on Lake Erie.

Dress warmly for spring visits to this preserve as the wind coming off Lake Erie can be brutally cold. Be prepared for muddy and uneven terrain walking along the series of dikes. Be sure to bring along binoculars or a spotting scope if you have one. Closure of certain trails is possible during eagle nesting periods; therefore, watch for posted closure signs.
