Overview

Description

Erie Marsh represents 11% of the remaining marshland in southeastern Michigan and is one of the largest marshes on Lake Erie. Located on North Maumee Bay, it is one of the largest coastal wetlands on Lake Erie, supporting numerous animals and plants that would otherwise be hard-pressed to find suitable habitat. The most significant feature of this area is its role as a migratory and nesting area for shorebirds, waterfowl, land birds, and in the fall, raptors. It also harbors some of Michigan’s few remaining colonies of American lotus and swamp rose-mallow—both listed as state-threatened.

In 2011, TNC implemented a multi-year project to restore 946 acres of highly degraded coastal wetlands at Erie Marsh. This connected the marsh to Lake Erie, providing access to key spawning areas for fish, controlling invasive species (most notably, Phragmites) and improving the overall quality of the wetland.

Where Migratory Birds Rest and Nest

No matter the time of year, Erie Marsh Preserve offers refuge to tens of thousands of migratory birds that touch down to rest, refuel and sometimes nest here. Bring binoculars and you might see: Bald eagles, great egrets, great blue herons, black-crowned night herons, blue- and green-winged teals, mute and trumpeter swans, and more!

Background

When The Nature Conservancy acquired this preserve in 1978, it was essentially 2,200 acres of highly altered, degraded wetland habitat that had been divided by barrier dikes and separated from Lake Erie since the 1950s.

That all changed in 2011, when TNC embarked on a multi-year project to restore 946 acres of high-priority coastal wetlands. Over the past decade, we have refurbished extensive marsh and wetland habitat, rehabilitated degraded levees and installed a fish passage structure that reconnected the marsh to Lake Erie’s North Maumee Bay.

Native fish and other aquatic life are now accessing new breeding and spawning areas for the first time in more than 60 years. The reconnection between wetland and lake has also helped control invasive Phragmites, allowing some of Michigan’s few remaining colonies of the state-threatened American lotus and swamp rose-mallow to thrive.

Restoring Erie Marsh (5:04) Only 5% of western Lake Erie’s original 300,000 acres of wetlands remains today, and Erie Marsh contains 11% of the wetlands left in southeast Michigan. This, along with its location within the Atlantic migratory flyway, make Erie Marsh Preserve a critical priority for coastal wetland restoration.
