Maine Nature Guide

Maine is the most heavily forested state in the nation, a vast Acadian woodland of spruce, fir, pine, and northern hardwoods stitched together by thousands of lakes, peat bogs, and a deeply rugged coastline. From the alpine summit of Mount Katahdin and the boreal North Woods down to the puffin colonies and tide pools of the Down East coast, the state runs cold and northern — USDA zones 3b in the far north to 6a along the warmer coast — giving it a sharp seasonal calendar of long snowy winters, a late explosive spring migration, brief cool summers, and a sweeping autumn of maple, birch, and red blueberry barrens.
