Guadalupe Mountains National Park Plants

The biological diversity within Guadalupe Mountains National Park is outstanding and includes more than 1000 species of plants. While many of these are common desert inhabitants such as ocotillo or prickly pear cactus, others are found only in the park and nowhere else in the world.

In part, the amazing diversity can be attributed to significant geographical variations in an extremely rugged landscape. Steep-walled canyons, high country ridge tops, huge expanses of open desert lowland, and lush riparian oases provide opportunity for unique and contrasting life zones that span across thousands of acres with over 6000' in elevation difference.

Plants that grow here are tough. They survive not only the components that make up the landscape, but also the extremes of temperature, aridity, and relentlessly powerful winds, all common factors of the park's desert climate. Plants have evolved elegant methods of tolerating or avoiding desert conditions. Some such as cactus have thick fleshy stems that store water, and spines that not only serve as fierce armor against predators, but also help reflect the sun's radiant heat. Many species avoid desert extremes by clinging tightly to limited but dependable seeps and shaded springs. Annual wildflowers that grow here avoid the drought altogether with a compressed complete life cycle - from sprout to seed - that occurs only in conjunction with summer's monsoon rains.

Maine Puffins


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.
