متن کاملPost - drought growth responses of western juniper ( Juniperus occidentalis var . occidentalis ) in central Oregon Paul
Increased atmospheric CO2 may affect the physiological response of natural trees to drought. We examined radial growth rates developed from five western juniper chronologies to determine if post-drought growth responses have changed. Using prior year October to current year June precipitation from 1896-1998, we identified drought recovery years as having standardized scores (z-scores) > 0 and p...
متن کاملNew Findings in the Determination of the Mechanical Properties of the Wood of Western Juniper ( Juniperus occidentalis Hook . ) Report of 13 September 2007 Edwin

متن کاملSagebrush steppe recovery after fire varies by development phase of Juniperus occidentalis woodland
Woodland ecosystems of the world have been changed by land use demands, altered fire regimes, invasive species and climate change. Reduced fire frequency is recognised as a main causative agent for Pinus–Juniperus L. (piñon–juniper) expansion in North American woodlands. Piñon–juniper control measures, including prescribed fire, are increasingly employed to restore sagebrush steppe communities....
