Flora & Fauna
wells national estuarine research reserveThe Wells Reserve at Laudholm protects diverse habitats that support a rich flora and fauna. Many of these plants and animals are subjects of public enjoyment and scientific study.
Mammals
The harbor seal is the only marine mammal noted from the Wells Reserve, but land mammals living here include bats, squirrels, mice, muskrat, porcupine, coyote, fox, raccoon, fisher, otter, and deer. Bear and moose are unusual. Rare species include the New England cottontail.
Birds
Laudholm Farm was known to be an excellent place for bird watching long before the Wells Reserve was created. Since the 1980s, about 260 species have been reported on and adjacent to the lands and waters managed by the Wells Reserve. Our wide variety of habitats support diverse breeding and migratory populations and the beaches and salt marshes are included in the Wells Important Bird Area. The Wells Reserve has supported a bird-banding program since 1988 and collaborates closely with the York County Audubon Society on a number of initiatives.

Invertebrates
Estuaries are important for many intertidal and subtidal invertebrates, notably softshell clams, green crabs, and sandworms. Wells Reserve projects have also included several focusing on insects, especially dragonflies, damselflies, butterflies, and species that emerge from the salt-marsh surface.
