Fish Lake Meadow is a vast northern sedge meadow bordering Fish Lake dominated by wire-leaved sedges and rushes. Dominant species are American woolly-fruit sedge, cord-root sedge, mud sedge, beaked sedge, few-seeded sedge, cotton-grass, and Juncus. Other plants include blue-joint grass, round-leaved sundew, narrow-leaved sundew, marsh cinquefoil, bog St. John's-wort, and steeplebush. Islands of leather-leaf and sphagnum moss are scattered throughout the site. Larger islands support shrubs such as speckled alder, white meadowsweet, black chokeberry, bog birch, and willows. A few trees are also present, mainly paper birch, red maple, and tamarack. The meadow is very wet, often with 4-12" of standing water. Bird life is diverse and includes a number of rare or uncommon species such as sharp-tailed sparrow (Ammodramus nelsoni), Le Conte's sparrow (Ammodramus leconteii), yellow rail (Coturnicops noveboracensis), Wilson's phalarope (Phalaropus tricolor), American bittern (Botaurus lentiginosus), black tern (Chlidonias niger), northern harrier (Circus cyaneus), and sedge wren. The 200-acre Fish Lake occupies the northwest portion of the site. Fish Lake Meadow is owned by the DNR and was designated a State Natural Area in 2003.
