With 26 million acres of woods, rivers, and lakes, the Northern Forest is the largest and wildest remaining expanse of forestland east of the Mississippi River.

Sometimes called America’s First Great Forest, the Northern Forest was first settled by humans 10,000 years ago. It stretches 400 miles from Lake Ontario to the Atlantic Ocean, across New York's Tug Hill plateau and Adirondack Mountains and across nearly all of northern Vermont, New Hampshire, and Maine, reaching into Quebec and the Maritime Provinces of Canada and the higher hills and mountains of the rest of New England.

About one million people call the Northern Forest home, living in small rural communities that depend on the forest and its related industries- primarily paper, timber, and tourism - for economic viability. The forest’s residents are intimately connected to the landscape, as their culture and heritage illustrate, working in the region’s disappearing paper mills or in the forests as loggers. They are farmers, small businesspeople, and artists. What ties them together is their connection to the forest, a tie that for many goes back generations.

An estimated 10 million people visit the Northern Forest each year, coming to hunt, hike, fish, and ski or simply to camp amongst the trees, relax at a small inn, or stroll around a New England village. The Northern Forest is home to many popular recreation areas—including the Adirondacks, Green Mountains, White Mountains, and Maine’s Mt. Katahdin region—all of which host visitors every season of the year.

OSI At Work

  • OSI has lent $5 million to its Northern Forest partners and granted an additional $10 million to acquire land.
  • The land OSI has acquired ranges from forest that has been heavily harvested and will now be recovered to a stretch of woods that contains a variety of rare wildlife and fauna and more than 20 miles of rivers and streams.
  • An OSI loan saved Mirror Lake, New Hampshire from development. The Hubbard Brook Research Foundation has used Mirror Lake for long-term ecological research, including a landmark study linking acid rain to increasing levels of air pollution.
  • A grant from OSI helped The Forest Society of Maine save important habitat for loons, pine marten and Canada lynx.
