Desert Bighorn Sheep Research

Keeping Texas Wild

TPWF partners with the Borderlands Research Institute at Sul Ross State University to better understand the challenges affecting Texas' bighorn sheep population.

About this Project

The bighorn sheep population has declined as much as 50 percent in Texas since 2020. The disease causing the decline has been identified, but the extent to which the disease impacts herds in Texas is unknown.

There has been much research into the disease affecting bighorn sheep in other western states. This wealth of knowledge can help officials in Texas make informed decisions about how to approach the problem here.

Working together with TPWD and BRI, efforts are being made to better understand how the problem of bighorn sheep population decline can be addressed.
