Nature Trail

The Living Desert is more than a collection of exhibits. It is also a nature preserve. In fact, 1080 of our 1200 acres are undisturbed Sonoran Desert. Within this preserve is a series of nature trails. From The Living Desert, a hiker can select one of three trails to suit their desired experience of the real undisturbed desert. The inner loop is a brief ¼ mile interlude, the outer loop rambles for a mile through desert wash habitat and across a rocky bajada while the wilderness loop offers an adventurous 3 ½ mile hike up or down a boulder strewn canyon and along a rocky ridgeline with far reaching vistas.

This plant list has been compiled from observations over nearly 60 years and only includes species that are native or that have become naturalized along the trail system. Currently this list contains over 160 species of which 16 (10%) are introduced – 9 of them are grasses. Out of the 152 known natives, 55 (36%) are perennial and 97 (64%) are annual or biennial.

Thirty-six families are represented, the largest of which is the Aster Family (Asteraceae) with 23 species. Cactus usually associated with desert, is ranked number 10 with only 6 species. Twelve families are represented by only one individual species.

The first plant list done on the grounds of The Living Desert was compiled in March of 1954 by Dr. E.C. Jaeger; legendary botanist, writer, naturalist, educator and artist deemed Dean of the American Desert. Dr. Jaeger toured the property again soon after The Living Desert’s opening helping to augment the fledgling organization’s plant knowledge.

For uniformity, taxonomy follows The Jepson Manual – Vascular Plants of California, 2nd Edition (2012). “Old Name” column lists the name or change from the original list based on Munz (1974) A Flora of Southern California. Many of the common names are derived from Desert Wildflowers by Dr. Jaeger.
