Plants

Nature and Science

Devils Postpile National Monument's vegetation is a montane forest dominated by red fir and lodgepole pine. The monument's proximity to both west and east sides of the Sierra Nevada results in the presence of plants from diverse biological communities. Recent plant inventories documented 360 plant species in the relatively small 798-acre area of the monument. Along the San JoaquinRiver and the few creeks that flow into it, typical montane riparian vegetation can be found, such as quaking aspen, black cottonwood, alder, and willows. Both wet and dry meadows dot the monument and during the spring and early summer when water is available, a colorful bouquet of wildflowers can be found.

The area now known as Devils Postpile National Monument used to be part of Yosemite National Park.  In 1905, the Devils Postpile formation, Rainbow Falls, and the Minarets were removed from Yosemite's boundaries due to pressure from mining interests.
