Grand Canyon National Park Scrublands

Grand Canyon National Park scrublands are more precisely called desert scrub communities. A Mohavean desert scrub community extends from the Grand Wash Cliffs in extreme western Grand Canyon to near the Colorado River's confluence with the Little Colorado River. It is typified by warm desert species such as creosote bush and white bursage. Frost-sensitive species more characteristic of the Sonoran Desert such as brittle brush, catclaw acacia, and ocotillo can also be found along this stretch of the river.

Species such as mariola, western honey mesquite, and four-wing saltbush, considered typical of Chihuahuan Desert species, also grow here. Upstream of the Little Colorado River, in Marble Canyon and on the Tonto Platform, species more characteristic of the Great Basin Desert predominate, such as big sagebrush, blackbrush, and rubber rabbitbrush.

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.
