Estimates of the probability of mortality in whitebark pine from mountain pine beetles as determined from a logistic generalized additive model of the presence of mortality as functions of the number of trees killed last year, the percent whitebark pine in each cell, minimum winter temperature, average fall temperature, average April - Aug temperature, and cummulative current and previous year summer precipitation. Analysis was done at a 1 km grid cell resolution. Data are a list of points in comma separated text format. Point coordinates are the center of each 1 km grid cell.

Estimates of weather suitability for the occurrence of mortality in whitebark pine from mountain pine beetles as determined from a logistic generalized additive model of the presence of mortality as functions of the number of trees killed last year, the percent whitebark pine in each cell, minimum winter temperature, average fall temperature, avverage April-Aug temperature, and cummulative current and previous year summer precipitation. Analysis done at a 1km grid cell resolution. Weather suitability index calculated by summing the weather terms in the model. Calculated for 2010 through 2099 based on downscaled data from various emissions scenarios. GCMs include: BCC, CanESM, CCSM, CESM, CESM-BGC, CMCC, CNRM, Had-CC,...

In British Columbia, Canada, management efforts used to control mountain pine beetle (Dendroctonus ponderosae Hopkins) outbreaks have included treatment of infested trees with an organic arsenic pesticide, monosodium methanearsonate (MSMA). Cumulative pesticide applications over a large geographic area have generated concerns about arsenic loading in the environment and potential toxicity to nontarget wildlife. We investigated woodpecker foraging patterns in infested stands with and without MSMA treatment using a combination of tree debarking indices, point count surveys, and radiotelemetry methods in addition to insect flight traps to measure mountain pine beetle emergence. Debarking indices indicated woodpecker...

Droughts and insect outbreaks are primary disturbance processes linking climate change to tree mortality in western North America. Refugia from these disturbances—locations where impacts are less severe relative to the surrounding landscape—may be priorities for conservation, restoration, and monitoring. In this study, hypotheses concerning physical and biological processes supporting refugia were investigated by modelling the landscape controls on disturbance refugia that were identified using remotely sensed vegetation indicators. Refugia were identified at 30-m resolution using anomalies of Landsat-derived Normalized Difference Moisture Index in lodgepole and whitebark pine forests in southern Oregon, USA, in...

This record contains three zip files of data. First, for the file treeGeneticISSRData, the data consists of genetic ISSR band scores. Two sets of trees were sampled for genetic analyses - large trees surviving mountain pine beetle and 'general population' trees that we just a little to small to be attacked that served as a proxy for the population without beetle selection. Second, for the file Treegrowthdata_, this dataset includes files that record tree ring widths of trees by year from two sites, Vipond Park and Lacey Creek, in Montana. Third, the file monoterpeneConcentrationsData contains spreadsheets of monoterpene concentrations from surviving and susceptible whitebark pine after a mountain pine beetle outbreak...

Synopsis: This study evaluated the effects of landscape management on the spread of mountain pine beetle colonization in Banff National Park, Alberta, Canada. Researchers used annual aerial survey data and geo-referenced locations of colonized trees that were cut and removed to assess if the area colonized and the spatial extent of pine beetles differed between monitoring and management zones. Pine beetles were allowed to follow their natural course in the monitoring zone, while an extensive eradication program involving cutting and burning colonized trees was established in the management zone. Management resulted in no detectable effect on the scale of the zone. However, at the sub-zone scale, the area affected...
