The lake is ringed by a large, open sphagnum bog mat. The bog mat is surrounded by a coniferous swamp of tamarack (Larix laricina) and black spruce (Picea mariana). The bog mat supports a plant community that is considered diverse and unusual, with several rare species present, including: bog arrow-grass (Triglochin maritima), dragon's mouth orchid (Arethusa bulbosa), livid sedge (Carex livida), small-headed bog sedge (Carex tenuiflora), as well as one of only a few known populations of bog rush (Juncus stygius) in the State of Wisconsin. In 1991, the US Forest Service designated the site as a Research Natural Area. Also, the site is listed as one of Wisconsin's Wetland Gems, by the Wisconsin Wetlands Association.[1][2][3] Location and accessGrandma Lake Wetlands is located within the Nicolet National Forest, in southwest Florence County, approximately {{convert|3|mi|km}} southeast of Long Lake. Access is via a walking trail that leads west from Grandma Lake Road, approximately 0.5 miles south of its intersection with Tie Mill Road. A small, brown breeding bird survey fencepost marks the trailhead.[4] {{gallery|mode=packed|align=center|width=165|height=165|File:GrandmaLake2.jpg|Wide, open bog mat on the northeast side of Grandma Lake |File:GrandmaLake3.jpg|Black spruce and tamarack muskeg at the north end of Grandma Lake |File:GrandmaLake4.jpg|A close-up of the bog mat, near the northeast shore of Grandma Lake }} References1. ^{{cite web | author = Fouse, Fred | title = Establishment Record for Grandma Lake Wetlands Research Natural Area within the Nicolet National Forest, Florence County, Wisconsin. | url = http://www.nrs.fs.fed.us/rna/documents/establishment/wi_nicolet_grandma_lake_wetlands.pdf}} 2. ^{{cite web | author = Wisconsin Department of Natural Resources | title = Grandma Lake Wetlands State Natural Area | url = http://dnr.wi.gov/topic/Lands/naturalareas/index.asp?SNA=305 | accessdate = 2013-11-29}} 3. ^{{cite web | author = Wisconsin Wetlands Association | title = 100 Wetland Gems | url = http://www.wisconsinwetlands.org/gemslist.htm | accessdate = 2013-11-29}} 4. ^{{cite map | publisher = Wisconsin Department of Natural Resources | title = Grandma Lake Wetlands State Natural Area | url = http://dnr.wi.gov/topic/lands/naturalareas/documents/topomaps/map305.pdf | accessdate = 2013-11-29}} External links
