These maps are a digital representation of the individual tree species range maps of the Atlas of the United States Trees by Elbert L. Little, Jr. The atlas shows the natural distribution or range of the native tree species of North America. These coverages represent 3 volumes of the atlas.

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.
This webinar was recorded on May 7, 2015. Sustainable management of natural resources under competing demands is challenging, particularly when faced with novel and uncertain future climatic conditions. Meeting this challenge requires the consideration of information about the effects of management, disturbance, land use, and climate change on ecosystems. State-and-transition simulation models (STSMs) provide a flexible framework for integrating landscape processes and comparing alternative management scenarios, but incorporating climate change is an active area of research. In this presentation, three researchers present work funded by Climate Science Centers across the country to incorporate climate projections...

The viability of the whitebark pine (Pinus albicaulis) species is under threat due to precipitously declining populations. This study investigates the sources of differing levels of concern about climate-driven effects on whitebark pine trees. It also investigates support for different Whitebark Pine (WBP) management strategies on federal public lands.

Abstract (from http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0111669): Projected climate change at a regional level is expected to shift vegetation habitat distributions over the next century. For the sub-alpine species whitebark pine (Pinus albicaulis), warming temperatures may indirectly result in loss of suitable bioclimatic habitat, reducing its distribution within its historic range. This research focuses on understanding the patterns of spatiotemporal variability for future projected P.albicaulis suitable habitat in the Greater Yellowstone Area (GYA) through a bioclimatic envelope approach. Since intermodel variability from General Circulation Models (GCMs) lead to differing predictions...
Landscape simulation modeling will be used to develop detailed management guidelines for restoring and sustaining whitebark pine under future climates, accounting for the principal stressors that threaten its persistence (exotic disease infections, mountain pine beetles, and fire exclusion policies). We will build on existing work, including the 2012 publication A Range-Wide Restoration Strategy for Whitebark Pine Forests and existing simulation areas within critical whitebark pine habitat. This project will create a robust and trans-boundary set of management tools for creating resistant and resilient whitebark pine forests within the Rocky Mountains, USA and Canada.FY2013Objectives:We propose to use FireBGCv2...

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...

Projected current and future distributions of two tree species, Pinus albicaulis (Whitebark pine), Artemisia tridentata (Big Sagebrush), based on empirical bioclimatic models. Many recent changes in tree mortality, tree species distributions, and tree growth rates have been linked to changes in climate. Given that future climatic changes will likely surpass those experienced in the recent past, trees will likely face additional challenges as temperatures continue to rise and precipitation regimes shift. Managing forests in the face of climate change will require a basic understanding of which tree species will be most vulnerable to climate change and in what ways they will be vulnerable. We assessed the relative...

We assessed the vulnerability of ecological processes and vegetation to climate change in the US Northern Rocky Mountains with a focus on the Greater Yellowstone Ecosystem. We found that climate has warmed substantially since 1900 while precipitation has increased. An index of aridity decreased until about 1980 and then increased slightly. Projected future climate indicates warming of about 3-7 degrees C by 2100 and a substantial increase in aridity, depending on climate scenario. Snow pack, soil moisture, runoff, and primary productivity are projected to decrease dramatically in summer under future climate scenarios, with snow pack and runoff declining annually. Habitat suitability for the four subalpine tree species...
Existing climate change science and guidance for restoring and maintaining whitebark pine forests will be evaluated using landscape simulation modeling to inform implementation of the Greater Yellowstone Coordinating Committee (GYCC) Whitebark Pine (WBP) subcommittees WBP Strategy. We will design a no constraints management scenario based on the GYCC WBP Strategy and 2015 publication Restoring whitebark pine ecosystems in the face of climate change and incorporating the latest projections of future climate suitability for WBP and other landscape stressors (mountain pine beetles, competing species, wildland fire). We will use the landscape simulation model FireBGCv2 to simulate interactions of future climate, mountain...
