Trees and Shrubs

Most tree species are found in higher elevations in the park, or are restricted to canyons and riparian zones.

In much of the Chihuahuan desert, shrubs, succulents, and cacti, dominate the landscape, while trees are few in number and in total number of species. Trees generally need more water, cooler temperatures, and higher humidity than the desert climate has to offer, and that restricts them to ridge tops, canyons and riparian zones. Those that do grow in the lower desert elevations, such as honey mesquite, Prosopis glandulosa, often grow no taller than shrubs and are easily confused with shrubs because they possess similar physical characteristics such as small leaves and sharp spines.

Shrubs, on the other hand, are numerous and widespread in the Chihuahuan desert. Average elevations in this desert (above 3000’) allow for colder winters which many shrub species can tolerate, while most cacti and succulents cannot.

Did You Know?

Flowers of the desert willow are perfectly formed for the fat, rounded bodies of bees.

The long narrow leaves of the desert willow (Chilopsis linearis) gives it its common name, but it is not a true willow. It is beautiful when in bloom, and provides valuable nectar for hummingbirds, butterflies, bees and other insects.
