Pinon pine mortality event in the Southwest: An update for 2005

Abstract

(Please note, this is an abstract only) Drought conditions in the Southwest have persisted for a number of years resulting in large areas of pinon pine mortality. In 2002 drought conditions became extreme, facilitating an outbreak of pinon ips beetles (Ips confusus, Coleoptera: Scolytidae) that killed many millions of pinon pines over a six-state region by 2003. In response to this unprecedented mortality, Forest Health Monitoring provided funds to Forest Health Protection units to measure the extent and intensity of the event. These impacts are being documented through an extensive network of permanent plots that were installed throughout much of the range of pinon in the southwestern United States in 2003 and 2004.
