Ottawa NWR--Marinewood Unit

About this Location

The Marinewood Unit is located on OH-163 between Oak Harbor and Port Clinton. It is the old Marinewood Golf Course. Since being acquired by the U.S. Fish and Wildlife Service in 2014, it is now the site of a pollinator restoration and tree restoration project. As the Refuge Private Lands Biologist said, “Can you think of any better place for a butterfly?”

The Friends of Ottawa National Wildlife Refuge are working to restore the property and provide additional public use opportunities in the coming years. A kayak launch, restroom, gravel trail, and RV camp host site are planned for this area.
