Our Protected Land

Grosse Ile Nature and Land Conservancy protects over 175 acres of land either by direct ownership or by administering conservation easements. We are the only private organization in the Township of Grosse Ile that can legally protect property either by direct ownership of land or by holding conservation easements. In turn, we are obligated to manage our properties with the best land management practices, balanced by public benefit.

Detroit River International Wildlife Refuge - Gibraltar Bay Unit (GBU):  28820 East River Rd, Grosse Ile. 
Because this is now federally owned, this is not an official GINLC preserve. However, GINLC has a long history of preservation efforts on this property and the adjacent Airport Natural Area. This 40.5-acre marsh and upland area was previously a Navy seaplane base (1927) and also a NIKE missile base (1954 to 1963). In 1972 the Defense Department turned this site over to the Environmental Protection Agency ("EPA") for use as a wetlands research area. In April of 1990, at the center of the property, six acres of meadowland were still completely covered with pavement and huge steel doors were lying on the ground. Underground there were three large vaults each containing a NIKE missile. In 1990, the doors were removed, the cement was hauled away, and Nature, with a little help from man, could once again flourish. In 1993, the EPA granted stewardship of the area to the Grosse Ile Nature and Land Conservancy. In 2009 the Nature Area was made part of the Detroit River International Wildlife Refuge.   GBU includes a pond and a variety of habitats including Gibraltar Bay and provides access to the Airport Natural Area. 

The Airport Natural Area (ANA) is adjacent to the GBU, is accessed via the GBU entrance at 28820 East River Rd, Grosse Ile, and is owned by Grosse Ile Township.  However, GINLC has a long history of preservation efforts on this property, and the adjacent Gibraltar Bay Unit. After completing a project in 2023, with the Commerce Park Commission, the ANA is now accessible for pedestrian and bicycle traffic from dawn to dusk every day of the week.  Our organization, the Grosse Ile Nature & Land Conservancy (GINLC), has a deep-rooted history with the ANA, dedicating ourselves to preserving this cherished natural space. We have diligently stewarded the trails, implemented numerous improvement projects, and ensured the protection of its abundant wildlife, diverse bird species, and precious natural habitats. The ANA is truly a gem within our island, offering a wealth of opportunities for observing nature in its unspoiled beauty, including the Sedge Marsh, Lagoon, Hiking Trails, and Lookout points.
