Abstract:
Widespread mortality in the pinyon-juniper forest type is associated with several years of drought in the southwestern United States. A complex of drought, insects, and disease is responsible for pinyon mortality rates approaching 100% in some areas, while other areas have experienced little or no mortality. Implementation of the Forest Inventory and Analysis (FIA) annual inventory in several states coincided with the onset of elevated mortality rates. Adjunct inventories provided supplemental data on damaging agents. Preliminary analysis reveals the status and trends of mortality in pinyon-juniper woodlands.Keywords: forest inventory; FIA; pinyon pines; pinyon-juniper woodlands; drought; mortality; Ips confusus; bark beetles; southwestern United States; environmental management; forest; forest management; forest resources; forestry; forestry research; forestry science; natural resources; natural resource management
