Joshua Tree National Park, located in Johsua Tree, California, is a place full of life. Within the desert landscape of the park live many beautiful and elusive creatures. In the year that I lived there, I saw that as the seasons changed, so did the the animals, plants, birds and reptiles that populated the rocky outcrops and sandy valleys.

Summer

Summer is hot and dry, but occasionally summer monsoons hit and old Barker Dam fills up and becomes a temporary lake. When that happens many organisms come to life! The most surprising development of the weeks of water were the thousands of red spotted toads that hatched and began to hop about in all the nooks and corners of the newly formed lake and puddles in the desert around it. Equally as miraculous were the birds, such as a white crane, that came to partake of the cool water. At night the dam is closed to visitors so that Bighorn Sheep can drink in peace in the evenings.

One afternoon as we climbed on a rock formation, two mojave rattlesnakes appeared. One coiled and rattled, the other darted toward us and looked as if it were attempting to ascend the face.

Autumn

In a year of monsoon the riot of life that explodes after the water has come is an amazing sight. In autumn, after the rains, the red spotted toads grew larger, the coyotes gorged on ripe prickly pears, and yellow chinchweed carpeted the desert sands. Even columbines grew in sandy washes. Less welcome was the profusion of ragweed which caused everyone around a lot of sneezing and wheezing! Also a nuisance were the introduced bullfrogs that are known to decimate some native species.

...In the afternoons Antelope ground squirrels scurry around the rocks, but a bitter wind often blows. As the sun sets, the dry grass glitters in the sun. Winter is coming!

Winter

Joshua Tree National Park encompasses two deserts, the Colorado Desert, a western extension of the Sonoran Desert, and the Mojave Desert. Taking a trip to the south end of the park, and warmer weather, one can see flora of the Sonoran Desert, like ocotillo, and brittlebush, still blooming. Back in the Colorado, and in the realm of the Joshua Tree, everyone hopes for snow. It is theorized that Joshua Trees may branch off after a frost.

Winter migrants arrive, I sight the white-crowned sparrow and dark-eyed junco that have come to visit. The ravens circle often, too many ravens now populate the park and threaten the existence of other winged creatures, as well as tortoises.

Spring

Spring is the time of wildflowers in Joshua Tree. Yellow, pink, white, purple and red extend over the sand in a profusion of color that is hard to believe after the months of beige and brown. Hurrah for spring! Spring in the desert feels like paradise. You can visit the Joshua Tree website to see what is in bloom.

Hurrah for spring! Spring in the desert feels like paradise. Wandering in remote areas of the park, I wonder, half in fear, half in excitement, if I might spot a shy mountain lion.
