Grand Canyon National Park Grasses
Some of the native grasses found in Grand Canyon National Park include Indian ricegrass, blue and black gramma, big galleta, and side oats gramma. Cheatgrass, smooth brome, red brome and Kentucky bluegrass are non-native, introduced species that often invade disturbed sites and compete with grasses indigenous to the park.
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.
