From the Rocky Mountain Research Station:
Blackbrush (Colegyne ramosissima) is a desert shrubland species that is currently dominant on over three million acres of the transition zone between the cold desert of the Great Basin and the warm desert of the southwestern United States. Western landscapes are projected to experience unprecedented changes as the climate warms, and researchers at the Rocky Mountain Research Station have been studying the response of this species to assess whether it can move upward in elevation and latitude.
