I recently visited Joshua tree National Park in the Southern California Desert. It was springtime wildflower bloom. This is a unique desert setting filled with Joshua trees at the upper elevation.
Two deserts, two large ecosystems primarily determined by elevation, come together in the park. Few areas more vividly illustrate the contrast between “high” and “low” desert. Below 3,000 feet (910 m), the Colorado Desert (part of the Sonoran Desert), occupying the eastern half of the park, is dominated by the abundant creosote bush. Adding interest to this arid land are small stands of spidery ocotillo and cholla cactus.
The higher, slightly cooler, and wetter Mojave is the special habitat of the undisciplined Joshua tree, extensive stands of which occur throughout the western half of the park. According to legend, Mormon pioneers considered the limbs of the Joshua trees to resemble the upstretched arms of Joshua leading them to the Promised Land.
