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 Plot number for each site (1-3) Total number of Juniperus monosperma that are alive in 2005 Total number of Juniperus monosperma that are dead in 2005 Total number of Juniperus monosperma in 2005 Total number of Pinus edulis that are alive in 2005 Total number of Pinus edulis that are dead in 2005 Total number of Pinus edulis in 2005 Total number of Pinus ponderosa in 2005 Total number of Juniperus deppeana in 2005 (or A.Junip) Total number of Quercus spp. in 2005 Total number of feather vane (a shrub) Total number of trees in 2005 Average btd of Juniperus monosperma per plot (100m2) Average btd of Pinus edulis per plot (100m2) Average btd of Quercus spp. per plot (100m2) Average btd of Junierus deppeanna per plot (100m2) Average btd of Pinus ponderosa per plot (100m2) Total canopy area (m2) of Juniperus monosperma in 2005 Total canopy area (m2) of Pinus edulis in 2005 Total canopy area (m2) of Pinus ponderosae in 2005 Total canopy area (m2) of Juniperus deppeana in 2005 Total canopy area (m2) of Quercus spp. in 2005 Total canopy area (m2) of trees in 2005 Total trunk basal area (cm2) of Juniperus monosperma in 2005 Total trunk basal area (cm2) of Pinus edulis in 2005 Total trunk basal area (cm2) of Pinus ponderosa in 2005 Total trunk basal area (cm2) of Juniperus deppeana in 2005 Total trunk basal area (cm2) of Quercus spp. in 2005 Total trunk basal area (cm2) of trees in 2005 Proportion of Juniperus monosperma dead in 2005 Proportion of Pinus edulis dead in 2005 Proportion of Juniperus monosperma and Pinus edulis dead in 2005 Arcsin (sqrt(Proportion of Juniperus monosperma dead in 2005)) Arcsin (sqrt(Proportion of Pinus edulis dead in 2005)) Arcsin (sqrt(Proportion of Juniperus monosperma and Pinus edulis dead in 2005)) Total number of Juniperus monosperma that are alive in 2005 per 100m2 Total number of Juniperus monosperma that are dead in 2005 per 100m2 Total number of Juniperus monosperma in 2005 per 100m2 Total number of Pinus edulis that are alive in 2005 per 100m2 Total number of Pinus edulis that are dead in 2005 per 100m2 Total number of Pinus edulis in 2005 per 100m2 Total number of Pinus ponderosae in 2005 per 100m2 Total number of Juniperus deppeana in 2005 per 100m2 Total number of Quercus spp. in 2005 per 100m2 Total number of trees in 2005 per 100m2 Total canopy area (m2) of Juniperus monosperma in 2005 per 100m2 Total canopy area (m2) of Pinus edulis in 2005 per 100m2 Total canopy area (m2) of Pinus ponderosa in 2005 per 100m2 Total canopy area (m2) of Juniperus deppeana in 2005 per 100m2 Total canopy area (m2) of Quercus spp. in 2005 per 100m2 Total canopy area (m2) of trees in 2005 per 100m2 Total trunk basal area (cm2) of Juniperus monosperma in 2005 per 100m2 Total trunk basal area (cm2) of Pinus edulis in 2005 per 100m2 Total trunk basal area (cm2) of Pinus ponderosa in 2005 per 100m2 Total trunk basal area (cm2) of Juniperus deppeana in 2005 per 100m2 Total trunk basal area (cm2) of Quercus spp. in 2005 per 100m2 Total trunk basal area (cm2) of trees in 2005 per 100m2
