The Atlantic Maritime ecozone encompasses all of Nova Scotia, New Brunswick and Prince Edward Island, as well as Quebec’s Gaspé Peninsula. The landscape is characterized by highlands with acidic soils, and coastal plains with richer soils. The Atlantic Ocean creates a cool, moist maritime climate.
With forest accounting for 82.3% of it, this ecozone is a transition between the deciduous and boreal forests, and a continuation of the Mixedwood Plains ecozone. With the long history of European settlement in the region, most of the native forest has been burned or harvested at least once; little old-growth forest remains.
