Green Mountains Region

Appalachian’s Corridor Territory of Action

We operate in the Northern Green Mountains, a key ecological link between the Northern Appalachians and Acadia regions. The Northern Greens are home to one of the most intact stretches of continuous temperate hardwood forest in the world.

Since nature knows no borders, our work embraces a cross-border vision, in harmony with conservation efforts taking place beyond the Canada–US border.

  • The Northern Green Mountains are an integral part of Appalachian Corridor’s territory of action.
  • The Green Mountains are part of the Northern Appalachians.
  • The Appalachians are a unique ecoregion with vast tracts of natural and old-growth forests that provide habitat for numerous species at risk.

The Northern Green Mountains Ecoregion

Our area of work is located in the Northern Green Mountains, the Québec portion of the Green Mountains. This range straddles the Canada–US border, stretching from southern Vermont to north of Mount Orford. It forms part of the Northern Appalachians and Acadian ecoregion, a globally unique area distinguished by its vast tracts of natural forest standing in close proximity to densely populated areas. It is one of the largest remaining intact natural forests near major population centres, harbouring exceptional biodiversity and numerous species at risk.

This ecoregion connects the temperate forests of the eastern United States with Canada’s boreal forests. Ecological connectivity — the extent to which the landscape allows species to move or ecological processes to occur, provided all other conditions are met — enables the movement of plants and animals. These movements are essential for species’ survival and reproduction. Moreover, in the context of climate change, species are expected to shift northward or to higher elevations in search of more suitable conditions.

Corridor Appalachien’s conservation strategy

A science-based approach

In response to the climate and ecological crises, we aim to promote a broad recognition of biodiversity and expand protected areas, while serving as the leading reference in conservation and ecological land-use planning.
