Description:
Uncas Dunes, located within the Anoka Sandplain, contains a relic dunefield associated with Glacial Lake Grantsburg. Natural plant communities found here include oak savanna, oak forest, and wetland. The rare Uncas skipper gives this site its name; this is one of only two sites in the state where this species is found. Other rare species here include sea-beach needlegrass and annual skeleton-weed. Active management includes prescribed burning and removal of planted pine trees to assist in restoration and enhancement of the sand prairie. The best time to visit is late summer when asters and goldenrods are in bloom.
