Booklets illuminate four rare plants Federally listed species take the spotlight in these free DNR publications A series of little-known booklets could help protect four of the nation's most threatened plants growing in Minnesota. The booklets were produced to help landowners, land managers, and nature lovers learn more about these rare plants.
Color photographs compare the rare species with common look-alikes.
Other images show the types of habitat where the species occur. Maps indicate which counties the species are located in. The booklets explain that a species is classified as federally endangered if it could become extinct within all or most of its range. Other booklets offer similarly interesting insights into these little-known plants. The only other two are in upstate New York, a large population on the shores of Seneca Lake.
