The easiest way to identify the alligator juniper is by its distinctive bark. Look for rough square-plated bark that resembles the skin of an alligator. The thick bark grows in a cracked or checkered and furrowed pattern that sets it apart from other trees. The leaves of the alligator juniper are a deep green to blue-green in appearance.

The Guadalupe Mountains is a perfect place for alligator juniper. The tree prefers dry hillsides at moderate elevations like those found in the Trans-Pecos region of the state. The tree grows in the company of piñons, ponderosas, oaks, and other junipers. Alligator juniper has a high tolerance for heat and a low requirement for water. This evergreen tree thrives in either alkaline limestone or slightly acidic igneous soil.

According to the science of  dendrochronology or the study of growth rings in trees, alligator juniper trees grow at a slow rate. Research has shown that young trees grow in diameter at a rate of 0.6 inches per decade — that’s pretty slow! The growth rate slows to 0.4 inches after the tree reaches 170 years of age. Alligator juniper trees have been known to live as long as 500 years. That’s pretty amazing!

The female tree produces edible berries that can be consumed raw or steamed. Native Americans used the strongly scented berries to flavor teas and incense and even added the berries to cornbread and sausages. Some Indians dried the berries for winter use or ground them into a mush and then formed them into cakes. In addition, they used the resin of the tree as chewing gum.
