According to the above map, the Lake of the Woods Golf Course and Stidham Woods are part of the Lake of the Woods Forest Preserve.  Also within its boundaries is a strip of land between the main body of the Preserve and Stidham Woods.

I request that someone with more OSM editing experience (than me) add those areas to the Forest Preserve's relation.
