Algonquin to Adirondacks A2A corridor


The Algonquin to Adirondacks Collaborative (A2A Collaborative) has as its mission the goal to connect people to the natural wonders and ecological importance of the Algonquin to Adirondacks region. To help you ‘Fall in Love with the A2A Region’ this autumn, A2A Collaborative has just published an article that highlights the impressive number of naturally beautiful hiking and walking trails within easy reach of 2+ million people on both sides of the US/Canadian border. Above: birds eye view of fall colours (Friends of Algonquin Park).

The article, “Get Outside in the Algonquin to Adirondacks,” was developed in partnership with the Ontario Trails Network and lists, for the first time, all 149 trails within the A2A Region and spotlights three closest to our major communities within the Region. The A2A Region comprises a total area in excess of 100,000 square kilometres (or 40,000 square miles), with almost 60 percent of that area on the Canadian side of the border.

“We hope that people will use this article and the information contained within to get out this Thanksgiving Weekend and begin to explore a critical link for wildlife in eastern North America,” said Nasha Choudhury, ecoExecutive Director of A2A Collaborative. “The Great Lakes – St. Lawrence waterway bisects eastern North America. The A2A region is the most important link across the waterway, because of its unusually high biodiversity and because it is anchored by the large Algonquin and Adirondack parks which are connected by the lightly developed Frontenac Arch. And in terms of natural ecology, the A2A Region ranks second in Canada for biodiversity, and the only north-south animal migration pathway (“wildway”) east of Thunder Bay.”
