From Texas Standard:
For over four decades, the U.S. and Mexican governments have worked to recover the population of endangered Mexican gray wolves. Thousands of these wolves once roamed from the southwestern U.S. all the way down to southern Mexico – but by the 1970s, only a handful remained in the wild.
A binational recovery strategy was created by U.S. and Mexican agencies in 2017 and renewed earlier this year. Last month, a pair of adult wolves was transferred from New Mexico to Chihuahua, Mexico.
