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.
Subregions:
• STL Glacial Marine Plain 212Ea
• STL Till Plain 212Eb
• STL Glacial Lake Plain 212Ee
• Black River Valley 222Ob
• Champlain Glacial Lake and Marine Plains 212Ec
• Champlain Hills 212Ed
