Entering off Interstate 10 last April, we took a brief byway tour of Joshua Tree National Park in hopes of seeing desert wildflowers. About 12 miles down a standard desert side road— narrow, winding and in some places almost washed-away—we got to Cottonwood Spring and its campground. Along the way and at the campground we saw wildflowers in abundance.

While not the sensational banks of color that California poppies or lupine present on grassy hillsides, desert wildflowers can be quite spectacular against the dun background of dirt, sand and rock. In the desert washes and canyon hillsides, flower colors from white to yellow to pink to red to blue stand out like banners announcing the arrival of spring. This year at the Park, the Joshua Trees themselves were especially prolific. Unlike most years when only a small percentage bloom, virtually all the trees were covered with blossoms in mid-April.

Scientists have a variety of theories as to the why—some think it’s because of “just right” weather conditions, others that it signals a desperate sign of drought and climate change. And the headlines bear these theories out. “Prolific Joshua Tree Bloom Could Signal Warming Climate” (KPBS, April 17, 2013) to  “Blooming Joshua Trees Wow Watchers, Surprise Scientists” (the California Report, April 19, 2013).

From the Huffington Post:

“Something mysterious is happening in the Mojave Desert’s Joshua Tree National Park. The reason may be grim but the effect is beautiful.

“It’s more than interesting, it’s probably unprecedented in anybody’s recent memory anyway,” Cameron Barrows, a research ecologist at the University of California, Riverside, told ABC…He’s talking about blooms on the Joshua trees that are larger than locals say they’ve ever seen.” (http://www.huffingtonpost.com/2013/04/12/joshua-trees-bloom-video_n_3070822.html)

The theory is that with the past two years of significant drought (in the Mojave annual average rainfall ranges from two to five inches, with last year posting only 0.7 inches) Joshua Trees have gone into survival mode, prolifically producing seeds to insure long-term survival.

Will it work? Or will the icon of the Mojave disappear? With reports of little to no reproduction in the last 30 years for some areas in its range it’s hard to be optimistic.
