The Pacific Crest Trail passes through the Laguna Mountains. Continuing north a couple hundred miles hikers come to Walker Pass Campground. Imagine looking forward to a nice place to spend the night. Hikers last summer, 2016, found this parched scene. About sixty percent of the Pinon pines and juniper were dying.
In recent years Pinon pines have died from drought and bark beetles in many parts of Arizona and New Mexico. Juniper are more drought hardy, but scientist Park Williams estimates that by 2050 Ponderosa pine (a close relative that interbreeds with the Jeffrey pine), Pinon pine and juniper will no longer grow in large areas of the southwest where they are found today, these places supporting grasslands or chaparral instead.
