The Northern Appalachian-Acadian Ecoregion

A globally important place

The Northern Appalachian-Acadian ecoregion stretches from New York to Nova Scotia. This globally significant region is the most intact temperate broadleaf forest remaining in the world. It is home to over five million people and thousands of species of wildlife and plants. The forests are vital to the region, providing economically important natural resources and livelihoods, clean water and air, and recreational spaces. Thanks to a large network of healthy forest, wetlands, and rivers, Canada lynx, black bear, moose, and other mammals roam freely across much of the landscape. The NAPA supports approximately 470 vertebrate species and over 2,700 species of plants, some of which are local endemics and rare.

This region stands out in eastern North America as a center of climate resilience. If we maintain and restore the landscape and its many interconnections, it could serve as a lifeboat for natural and human communities in the face of climate change.

A shared challenge and vision

Though much of the region remains in a natural state, habitat loss and permanent habitat conversion present significant challenges. These threats include residential and commercial development, unstainable forestry practices, changing ownerships, and road expansion. The region also faces rural de-population, water extraction, and new energy infrastructure. Climate will continue to aggravate these threats.

A landscape of large forest blocks, and intact corridors among them, will help safeguard the region’s native wildlife and plants in the face of these myriad challenges, while supporting the human livelihoods, activities, and values dependent upon a thriving forest.

Conservation must take place at many scales – from the town, village, and municipality, to the state, province, and country. Learn more about our mission, and read some of our publications for insight into how to move forward.
