Drought conditions throughout the past decade, and especially in 2002 followed by a bark beetle outbreak, have lead to high pinyon mortality (~20-80%) throughout Southwestern pinyon-juniper woodlands. This die-off of pinyons, and to a lesser extent junipers, may be viewed as a “thinning” of woodlands to pre-settlement conditions. Preliminary data suggest the highest pinyon mortality occurred in mature trees, but juniper mortality varied throughout the region. While contrary to other studies, woodland density was not a factor in overall tree mortality in this drought.
This dataset contains measurements on drought-related mortality made in 2005 in an area located in northern New Mexico. Measurements for each plot include:
Plot label. One site contains three plots. Plots are 100m2
location of the plot (1=north, 2=central, 0=south)
elevation (m)
Site contains three, 100m2 plots, set in a triangular formation. Each plot is 75m apart, creating a site
