Rocky Mountain National Park Ecosystem

Rocky Mountain National Park encompasses three different elevational ecosystems, the Montane, the Subalpine, and the Alpine. Variation in vegetation communities relates not only to elevation, but also to direction and amount of slope, drainage, moisture availability, exposure to wind, amount and type of soil, fire history, and other factors.The "boundaries" between ecosystems usually involve overlapping species and gradual transition rather than clear-cut points, but each ecosystem has some plants and animals, which are most frequently found within its limits.

Maine ocean islands provide the only nesting sites for Atlantic puffins in the United States. Eastern Egg Rock in the midcoast region, Seal Island and Matinicus Rock at the mouth of Penobscot Bay, and Machias Seal Island and Petit Manan Island off the downeast coast provide habitat for more than 4,000 puffins each summer.
