WHAT IS A2A?

The A2A Collaborative is a U.S., Canadian, and First Nations partner organization that works with scientists, policy-makers and a variety of conservation groups to protect and enhance the unique ecological features and functions of the A2A region. Our dream is a resilient, ecologically connected A2A region that sustains a full range of native wildlife and enhances people’s quality of life for generations to come. 

The Algonquin to Adirondacks (A2A) region ​
is a uniquely diverse bioregion that connects Algonquin Park to Adirondack Park through the Frontenac Arch and surrounding lands. Home to a vast array of plants and animals, it is one of the last large-scale, intact forest and wetland linkages left in Eastern North America. It provides the best remaining potential for wildlife movement across the Great Lakes-St. Lawrence system.  
Explore our site to learn more about A2A's work. Our initiatives include Road Ecology studies, Connectivity Mapping, Conservation Action Planning— focused efforts aimed at enhancing connectivity in this unique bioregion. We're dedicated to creating a resilient, connected landscape that supports thriving ecosystems and communities.
