  • Storm abatement
  • Flood storage/mitigation
  • Water quality improvement
  • Education

Numerous due to expansive size.  Highlights from NRCS websoil survey:  Freetown muck, ponded; Saco mucky silt loam; Hinckley loamy sand
 

Flora and Fauna
Dominant flora: "Extensive buttonbush-dominated wetlands reflect long-term vegetational changes along both rivers. In many areas, invasive species, such as water chestnut or purple loosestrife have displaced plant species of high waterfowl value, such as bur-reed and bulrush." (USFWS website)
Unique flora: Engelmann’s Umbrella-sedge (Cyperus engelmannii, state Threatened) and Few-seeded Sedge (Carex oligosperma, state Endangered),
Dominant fauna: Muskrat, great blue heron and numerous other terrestrial and avian species (migratory and residential)
Rare fauna: American Bittern, Blanding’s Turtle, Common Moorhen, Least Bittern, Umber Shadowdragon, Pied-billed Grebe, and King Rail
