Desert Diary
Plants/Junipers

rule

The juniper, often mistakenly called cedar by inhabitants, is a familiar tree of the mountain slopes throughout the Chihuahuan Desert region. Of course, it isn't really "the" juniper—rather, we are blessed with a number of different species, each with its own ecology and distribution.

Alligator Juniper tends to occupy the higher elevations, usually between 4,500 and 8,000 feet. Why name a tree after a crocodilian? Those of you who have seen this tree know the answer--the bark cracks into squares that nicely mimic the hide of our American Alligator. At lower elevations, One-seed Juniper and, in the northeast, Pinchot Juniper tend to take over. Grasslands degraded by overgrazing or drought tend to be invaded by these plants from their more common habitat of shallower, rocky soils. From the Chisos Mountains of Big Bend through the mountains of much of northern Mexico, the Drooping Juniper lends a unique look to the landscape with its drooping branchlets. All have in common the fragrance that Southwesterners never forget, once encountered.
