Immature male Belted Whiteface (Leucorrhinia proxima) –

flora and fauna are typical of other local wetlands.
Yellow Water Lily, Water Shield and Frogbit are the dominant aquatic plants;
emergent vegetation consists of Cattails and various species of graminoids.
The boardwalk makes it possible to study areas of the marsh that would normally be inaccessible except by canoe.
