Description
The Sustain Our Great Lakes Program is a public–private partnership administered by the National Fish and Wildlife Foundation (NFWF) to sustain, restore, and protect fish, wildlife, and habitats throughout the U.S. portion of the Great Lakes basin. The program funds on-the-ground projects that address key ecological issues such as habitat loss, water quality degradation, invasive species, and stormwater management. Major funding is provided by the Great Lakes Restoration Initiative (GLRI) and program partners.
For 2026, the program will support projects in four main categories:
- Habitat restoration to conserve species and improve water quality (e.g., stream and riparian restoration, fish passage, wetland enhancement)
- Nature-based infrastructure in Great Lakes communities (e.g., stormwater storage, green infrastructure, urban forestry)
- Invasive species control to protect and enhance previously restored habitats
- Activation and stewardship of restored habitats and natural areas (e.g., public access, engagement, long-term management)
Projects must occur within the U.S. portion of the Great Lakes basin and directly contribute to measurable program goals. The program encourages projects that leverage partnerships, community engagement, and innovative conservation approaches.
