When we climbed trails up in the Chisos Basin of the mountains of
Big Bend NP, there we found plenty of evergreens.

I am not very good at evergreen identification, so I don't know the exact species of the next pine tree but I think it is a pinyon pine.

I did learn that the only place north of the border where the Mexican Drooping Juniper, Juniperus flaccida, grows, is in Big Bend NP.

We also saw the Alligator Juniper, Juniperus deppeana, which is easily identified by the bark on its trunk.

The The Golden-cheeked Warbler depends on mature Ashe Juniper habitat,
Juniperus ashei, found in the Texas Hill country on the Edwards Plateau. This warbler only uses the shedded bark of this tree as nesting material. Only trees 40 to 50 years old, shred their bark.

Even among evergreen trees and plants, you can find color such as the red seed pods on the Evergreen Sumac,
Rhus virens, and the blooming evergreen Mountain Laurel,
Sophora secundiflora. I found Mountain Laurel in Big Bend NP but the photo is taken in
Lost Maples SNA.
