Northern Forest

The Northern Forest is one of the nation's great forest landscapes, well known for its charismatic wildlife, breath-taking autumn foliage, outdoor recreational opportunities and vast forested areas. 

It stretches from Maine through northern New Hampshire and Vermont and into the Adirondacks and Tug Hill Plateau of northern New York. 

The Northern Forest covers 26 million acres and is the largest continuous forest east of the Mississippi.


The Northern Forest is made up of a mixture of hardwood and boreal forests:

  • The hardwood forests (which include oak, sugar maple and beech trees) are found in the southern areas of the region.
  • The boreal forests (which include spruce and fir trees) extend north into Canada.

The diversity of ecosystems in this region provides habitat for many wildlife species, including moose, black bear, pine marten, Canada lynx, peregrine falcon and the bald eagle.

People and the Northern Forest

The abundant natural resources of the Northern Forest have supported people for over 10,000 years. It has long been the home of Native American communities, such as the Iroquois and Algonquian. European settlers took advantage of the Northern Forests' rich woodlands for harvesting timber and taking furs. Lumber and papermaking industries would later tap the rich forest resources too.

Currently, 2 million people live within the Northern Forest area, and 70 million people live within a day's drive.  Communities continue to rely on the forest resource for economic opportunity, subsistence and defining their way of life.  The Northern Forest is a globally important supplier of hardwood trees.

Recreational opportunities in the Northern Forest include:

  • Canoeing   (Take a tour of the region with the Northern Forest Canoe Trail)
  • Hunting
  • Fishing
  • Skiing
  • Hiking  (Follow the Appalachian Trail across some of the regions high peaks)
  • Wildlife Watching (Bird watch, harvest sugar maples for syrup, pick blueberries)

The Northern Forest is also where you will find the headwaters for major rivers in the northeast--including the Hudson, Connecticut, Penobscot and St. John's--that provide water for one quarter of the people in the United States. The region's seven thousand lakes and 2.5 million acres of wetlands provide valuable ecosystem services.

Wildlife in the Northern Forest

The Northern Forest is well known for its iconic wildlife, including the moose, black bear and brook trout. The region is also part of an internationally important bird breeding area.

  • Mammals: The Northern Forest's mammals include many beloved wildlife, including the moose, Canada lynx, black bear, snowshoe hare, white-tailed deer and beaver.
  • Birds: The Northern Forest has many different bird habitats.
    • On its mountaintops, you may find Bicknell's thrush, blackpoll warbler, Swainson's thrush, and yellow-rumped warbler.
    • In the conifer forests are boreal chickadees, Canada warblers, pine grosbeak, purple finches, and spruce grouse.
    • The Northern Forest region has many wetlands, lakes and ponds where you may find the common loon, American black duck, common goldeneye, and bald eagle.
    • The Hudson and Connecticut River valleys are important corridors for migratory birds including the Atlantic brant and green-winged teal.
    • The hardwood forests have black-throated blue warblers, ruffed grouse, yellow-bellied sapsuckers, blue-headed vireo, and rose-breasted grosbeak.  

Threats to the Northern Forest

Black Bear

The Northern Forest is under threat due to increasing pressure from development in the areas closest to large population centers like Boston and Portland and along the Connecticut River.

Throughout most of the 1900's, much of the land in the Northern Forest region was owned by timber companies.  Although the timber companies were not always the best stewards of the land, they did maintain their property in a forested manner that continued to provide wildlife habitat and ecosystem services. 

In the mid-1990's, the region began to change as the large timber companies sold their rights to forest lands they had owned for decades.  They fragmented larger parcels and sold them off piece by piece to private owners.  Each landowner makes separate decisions about the management of their land, sometimes without thinking about the larger needs of the surrounding forest habitat.  More than 80 percent of the Northern Forest is now privately owned, and may not have legal protection.

While much of the Northern Forest remains intact, increasing pressure for the money that development brings, along with increasing demand for housing in areas with growing populations, encourages private owners to sell, subdivide or develop their land.


Climate Change

Climate change may dramatically after the forest composition in the Northern Forest as some species, trees and wildlife, are no longer able to survive in the new climatic conditions.  In addition, opportunities for the forests to help address climate change through carbon sequestration will be lost as the forests are developed or unsustainably managed.
