Mapping Percent Tree Mortality Due to Drought in Piñon-Juniper ...
In the early 2000s, severe drought and beetle outbreaks brought on by climate change led to extensive piñon pine mortality in northern New Mexico. Mapping piñon mortality is critical for understanding and monitoring impacts to ecosystem services.
Carson National Forest - Resource Management - US Forest Service
An increase in ponderosa pine mortality from other species of bark beetles has already been documented during the Forest Service’s insect and disease aerial detection surveys this summer. Thinning can improve tree vigor in the long term, but the green slash generated by such activities can serve as ips breeding material if not properly handled.

Pinus edulis Engelm - US Forest Service Research and Development
Pinyon (Pinus edulis) is a small, drought-hardy, long-lived tree widespread in the southwestern United States. Its common name is derived from the Spanish piñon which refers to the large seed of pino (pine). For this reason the tree is known in the Southwest and throughout its range by this Spanish equivalent (49).
