Fish and Wildlife
The Basin’s fish and wildlife provide tangible economic benefits to the region. Bird watchers flock to the region to add bird species to their “life lists,” anglers and hunters are attracted by the abundant opportunities to harvest fish and wildlife, and researchers from around the world study the Basin’s unique ecosystem. In 1997, more than $204 million was spent on fishing-related activities in the Basin. The Vermont Agency of Natural Resources estimates that bird and other wildlife viewing activities generate at least $50 million a year.
While the Basin has an abundance of plants, fish, and wildlife, some species are listed as endangered or threatened at the state/provincial and federal levels. At present, more than 60 species are listed in New York, Vermont, and Québec.
Amphibians and Reptiles
Twenty-one species of amphibians have been identified as native to the Lake Champlain region. Of these, three are listed as endangered or threatened by either New York, Québec, or Vermont. Nineteen species of reptiles have been found in the Champlain watershed. Nine of these species are listed as threatened or endangered in at least one of the three jurisdictions of the Basin.
For many of these species, little is known about their population status and distribution in the Lake Champlain area. The New York Herp Atlas Project, a ten-year survey (1990-1999) of amphibians and reptiles, has helped provide a clearer picture of the geographic distribution of these species in New York. Additionally, the Vermont Reptile and Amphibian Atlas Project also is making great progress collecting and sharing information on the natural history, distribution, and conservation of Vermont’s reptiles and amphibians..
Taxonomic classification for some of these species is changing, as the use of DNA has allowed a more precise analysis of amphibian and reptile taxonomy. Exotic reptile species which have escaped captivity have been found on several occasions, although to date none has established a population.
In Vermont, the five-lined skink is presently known from only one locality. Vermont timber rattlesnake populations were decimated out of fear, for bounties, and by destruction of habitat. Only two known populations remain in the Vermont-portion of the Basin. Spiny softshell turtles in Lake Champlain are genetically separated from Great Lakes populations, and have been found only on the Vermont side of the Lake and in some Vermont tributaries. In Vermont, map turtles are restricted to Lake Champlain and the lower portions of its tributaries.
More than three hundred species of birds have been found to breed, overwinter, or pass through the Lake Champlain Basin on migration. A very visible part of the ecosystem, waterfowl and shore birds use the Lake Champlain Basin as breeding grounds, and for critical stopovers during spring and fall migrations along the Atlantic Flyway. Twenty-four bird species are listed by New York, Vermont and/or Québec as endangered or threatened.
Common threats to these species are destruction of habitat and declining water quality, particularly from persistent toxic pollutants. Lead also has harmed loons and other waterfowl. Lead sinkers have been banned in New York (1-oz or less in 2004) and Vermont (0.5-oz or less in 2007).
The Common Tern, an endangered species in Vermont and threatened species in New York, is a bird conservation success story in the Basin. The Common Tern Recovery Project, a joint effort of Audubon Vermont and Vermont Fish and Wildlife Department, has increased adult numbers on Lake Champlain by 300% since 1988.
Double-crested cormorants (Phalacrocorax auritus), considered a nuisance species by some, are certainly one of Lake Champlain’s most notorious birds. Cormorants were first recorded in Vermont during the 1930’s. In the 1970s they were seen near Young Island in Lake Champlain and in 1981 35 birds were recorded. Today, the number of nesting cormorants on Lake Champlain averages in excess of 4,000 pairs. The summer population is now estimated at 15,000 birds, about 98% of which nest on Young Island, VT and Four Brothers Island, NY. The current population target established by NYS DEC and VT DFW is 2,000-4,000 cormorants lake-wide at any point in the year.
On Lake Champlain cormorants have been nesting on Young Island, Mud Island in Panton, Bixby Island, Shad, Popasquash, and Four Bothers Islands. They like to nest on islands where they are more protected from humans and other predators. Double crested cormorants were added in 1972 to the list of species protected by the federal 1918 Migratory Bird Treaty Act. However, a ruling by the USFWS now allows certain population controls for the Lake Champlain region in areas where cormorants damage fisheries, vegetation and other birds. On Young and Four Brothers Islands cormorant guano has caused extensive defoliation which has negatively affected the nesting habitat for other birds like the black crowned night heron, cattle egret, great egret, snowy egret, and great blue heron.
These large black waterfowl are also of concern to fishermen who believe that the cormorants may be consuming game fish and significant numbers of yellow perch. A 2001-2002 study found that while cormorants do consume large quantities of yellow perch, they do not commonly feed on salmon, bass or trout.
In 2003, the USFWS ruled that cormorant management in Lake Champlain was allowed in areas where the birds damage fish, vegetation, and other birds. Methods used to reduce cormorants and protect other nesting birds include egg oiling and destruction of eggs and nests, lethal control of adults, harassment, and grid netting island areas to deter nesting. Populations on the islands fluctuate with the intensity of management efforts. While cormorants negatively impact other birds, management has helped: caspian tern nesting pairs have risen from one in 2001 to 50 in 2007; the common tern has also benefited from these efforts.
Seventy-eight native and 15 non-native species of fish have been identified in Lake Champlain. About twenty of these species are actively sought by anglers, including large and smallmouth bass, walleye, northern pike, chain pickerel, brown bullhead, channel catfish, yellow perch, lake trout, landlocked Atlantic salmon, rainbow (steelhead) trout, brown trout, and rainbow smelt. At present, ten species found in the Basin are classified as endangered or threatened by New York, Vermont, or Québec.
The Lake Champlain Fisheries Technical Committee, a sub-committee of the Lake Champlain Fish and Wildlife Management Cooperative, released a new Strategic Plan for Lake Champlain Fisheries in 2010. This new plan highlights goals for the fish community and the Lake Champlain fishery, including a framework to develop and guide fishery management programs for the Lake and its tributaries. In addition, the new plan provides a review of the history of fishery management in the basin, guiding principles, a suite of management actions and information priorities to help management agencies achieve these goals. Management actions will strive to prevent new introductions of invasive species and suppress current populations of nuisance species.

Five fish hatcheries or fish culture stations operate in the Lake Champlain Basin. These operations help to rehabilitate fish populations and expand the range of desirable fish. New York DEC, Vermont Fish and Wildlife Department, and the US Fish and Wildlife Service all maintain fish stocking programs in Lake Champlain and its tributaries, including: rainbow trout, lake trout, brown trout, and landlocked Atlantic salmon. Several of the hatcheries are open to the public. Contact the hatcheries directly for more information.

Invertebrates, including mussels, aquatic snails, and insects are a very important part of the Lake Champlain ecosystem. Surveys and studies of aquatic invertebrates in the Lake Champlain Basin have focused on freshwater mussels, dragonflies and damselflies, and for terrestrial species, butterflies, moths, and beetles (particularly ground beetles and tiger beetles). A rare dragonfly, the clubtail, is known from historic records to have inhabited the southern Lake Champlain Basin.
Fourteen native freshwater mussel species live in the Basin, but these native mussel populations are threated by nonnative zebra mussels. Zebra mussels compete with native mussels for resources and habitat and they also suffocate native mussels by attaching to their shells. Asian clam have been have been found close to the Basin for some time, but were found in the Basin in 2010 in Lake George. Eight freshwater mussel species are listed as threatened or endangered.
Other small shrimp-like invertebrates, called zooplankton, float in the Lake and its tributaries. All of these invertebrates are food for a huge variety of larger animals, such as small fish, frogs and turtles, and form the base of Lake Champlain’s food web.
Fifty-six species of mammals find their homes in the Lake Champlain area. Six species are listed as threatened or endangered by New York, Vermont and/or federal designation.
Many bat species have been affected by white-nose syndrome (Geomyces destructans). This fungus was first identified in bat colonies (hibernacula) outside of Albany, NY in February 2006; it was found in bat colonies throughout the New York and Vermont portions of the Champlain basin in the winter of 2007-2008 and was confirmed in Québec in 2010. The fungus has caused, directly or indirectly, nearly a 90% population decline in large bat hibernacula that are afflicted with the fungus. Population decreases of this magnitude could be beneficial to bat prey species (mosquitos and other insects).
Chronic wasting disease is an untreatable, fatal disease that afflicts the nervous systems of deer, elk and moose. Fortunately, it has not yet been discovered in the Basin. It was discovered in New York in 2005 in captive and wild deer herds in Oneida County, but hasn’t been seen since. It has not been found in Vermont or Québec. Management plans have been developed in New York, Vermont, and Québec to prevent it from arriving in the region.
Wildlife Management Plans
Management agencies have developed wildlife management plans for a number of species in the Basin.
The Lake Champlain Basin, including the shorelines of the Lake and associated wetlands, river shores, cliffs and bluffs, supports a diverse array of natural plant communities and many rare plant species. Cobble shores, sand beaches and dunes, low-gradient rivers, emergent marshes, bogs and fens, floodplain forests, maple-ash swamps, hardwood-cedar swamps, pine-oak-heath sandplain forests, oak-hickory forests, calcareous cliffs, alpine tundra, and cedar-pine lake bluffs are some important natural communities found in the watershed. The mineral-rich bedrock and soils of this region support natural communities high in plant diversity, including several plant species rarely encountered outside the region.
In the Vermont portion of the Basin, 56 plant species are listed as endangered or threatened under Vermont law. New York State published a list of protected native plants that includes endangered, threatened, vulnerable and rare species. One hundred and twenty species on this list are associated with Lake Champlain and its wetlands, tributaries, shorelines, and bluffs. Common threats to these rare plants and plant communities are land development and invasive species.
