In 1998, The Nature Conservancy identified the St. Lawrence – Champlain Valley Ecoregion as distinct from the larger Great Lakes Ecoregion, of which it had formerly been a part, based on the area’s unique patterns of vegetation, climate, hydrology and a more complete consideration of the Canadian portion. From mountain streams to the deltas and marshes that line the shores of the St. Lawrence River and Lake Champlain, this ecoregion is defined in a large part by the waters flowing through it and the relationship between the aquatic features and the land.

St. Lawrence Champlain Valley Ecoregional Plan:

Welcome to the first iteration of the STL ecoregional plan, an ecological assessment of the ecoregion. The first iteration contains the results of an ecological assessment of the ecoregion, conducted between 2000 and 2002. The draft report was distributed in July 2002.
