About
Discover a hidden ecological treasure at Grandma Lake Wetlands State Natural Area, a captivating landscape centered around a pristine 44-acre bog lake. This unique Wisconsin State Natural Area boasts a vibrant sphagnum bog mat encircled by a dense coniferous swamp dominated by towering tamarack and black spruce trees. It's a sanctuary for an unusual and diverse array of flora, including several rare and insectivorous plant species, making it a living laboratory for naturalists and a haven for those seeking untouched wilderness.
As you explore, keep an eye out for the fascinating insectivorous pitcher plants and round-leaved sundews, which thrive in the bog's nutrient-poor conditions. The area is also home to rare botanical gems like the vibrant dragon's mouth orchid and the state-endangered boreal rush, a species once unknown in Wisconsin. The wetlands support a rich birdlife, offering glimpses of the iconic common loon, the elusive merlin, and the distinct American bittern. Mammals such as snowshoe hare, mink, and white-tailed deer also inhabit this vibrant ecosystem.
