Three plant species with protected status in Minnesota are found here:
Threatened – Sullivant’s milkweed (Asclepias sullivantii)
Special concern – deer sedge (Carex hallii), four-flowered yellow loosestrife (Lysimachia quadriflora)
In early- to mid-June golden alexanders and heart-leaved golden alexanders paint the prairie yellow.
