Grandma Lake Wetlands State Natural Area, Protected natural wetlands in Florence County, Wisconsin.
The 495-acre natural area contains a 44-acre lake surrounded by a sphagnum bog mat and coniferous swamp of tamarack and black spruce.
The Wisconsin Department of Natural Resources designated this area as a State Natural Area in 1996, following its recognition as a Research Natural Area in 1991.
The wetlands contain rare plant species, including bog arrow-grass, dragon's mouth orchid, and one of Wisconsin's few populations of bog rush.
Visitors can access the wetlands through a walking trail from Grandma Lake Road, marked by a brown breeding bird survey fencepost near Tie Mill Road.
The lake lies in a depression formed during the last glacial period, creating specific conditions for an unusual plant community within the Nicolet National Forest.
