Request for Proposals: Weisgerber-Pohlmann Nature Preserve

The Black Swamp Conservancy (the “Conservancy”) is seeking proposals for a design-build wetland and riparian restoration project in northwest Ohio, funded by Ohio DNR with H2Ohio funds. 

The project is a whole-field restoration of an 18-acre agricultural field along the Tiffin River at the Conservancy’s Weisgerber-Pohlmann Nature Preserve near Evansport, Ohio, on the boundary between Defiance and Williams Counties.

Applicants are encouraged to submit proposals that will result in maximum nutrient reduction in the affected waterways and will restore quality fish and wildlife habitat.
