The arboreal desert

The Sonoran Desert of Arizona shares many of the same flora and fauna as the Chihuahuan Desert further to the east. Both deserts also share a similar climate and the same basin and range topography. Despite these similarities however, the Sonoran Desert presents a different visual aspect than its cousin to the east, largely because of the presence of taller stature plants. Towering Saguaros dominate the Sonoran Desert’s Arizona Upland to the extent that they become a feature of the landscape, but in addition, there is a profusion of small desert trees such as Palo Verde,Ironwood, and a number of others. This produces a striking contrast to the low stature vegetation which dominates the Chihuahuan Desert, and because of all its desert trees, the Sonoran Desert is sometimes called the arboreal desert.
