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 1km grid cell.
Potential Whitebark Pine range calculated by regression analysis (Keane, 2000).
The dataset contains 3 maps that show the current and predicted range of Whitebark pine (Pinus albicaulis) in the Pacific Northwest region. The layers include: 1) the species range modeled under current climate conditions for 1950-75 2) aÂ continuousÂ model of the predicted range for 1950-2006 and 3)Â potentialÂ range expansion and contraction from 2000-2009.

Quantifying the Effects of Climate Change on Mountain Pine Beetle Outbreaks and Subsequent Threats to Whitebark Pine
Whitebark pine is a high-elevation, important tree species that provides critical habitat for wildlife and supplies valued ecosystem services. These trees currently face multiple threats, including attack by the mountain pine beetle, which has recently killed whitebark pines over much of the western U.S. Climate is an important factor in these outbreaks, and future warming is expected to affect epidemics. Our project developed statistical models of outbreaks in whitebark pine for three regions: the Greater Yellowstone Ecosystem, the Northern U.S. Rocky Mountains, and the Cascade Range. We used these models to understand climate/beetle outbreak relationships, evaluate climatic causes of recent outbreaks, and estimate...
Putting climate adaptation on the map: developing spatial management strategies for whitebark pine in the Greater Yellowstone Ecosystem
Natural resource managers face the need to develop strategies to adapt to projected future climates. Few existing climate adaptation frameworks prescribe where to place management actions to be most effective under anticipated future climate conditions. We developed an approach to spatially allocate climate adaptation actions and applied the method to whitebark pine (WBP; Pinus albicaulis) in the Greater Yellowstone Ecosystem (GYE). WBP is expected to be vulnerable to climate-mediated shifts in suitable habitat, pests, pathogens, and fire. We worked with a team of biologists and managers to identify management actions aimed at mitigating climate impacts to WBP. Identified actions were spatially allocated across...
Montana Department of Fish, Wildlife and Parks (MTFWP) has been involved with developing a crucial areas statewide Decision Support System (DSS) since 2008 in parallel with activities from the Western Governors Association (WGA). In April, 2010, the Crucial Areas Planning System (CAPS) was released. Also in 2010, the WGA provided funding to the 18 western states to begin developing DSSs for crucial areas among and between the 18 western states. MTFWP will be piloting a transboundary DSS for fish, wildlife, and habitats along the Idaho-Montana Divide, beginning in July 2010. MTFWP will also participating in a dual role of advisory and collaboration with the Washington, Oregon and Idaho Columbia Plateau pilot project.This...
Landscape Trends (1753-1993) of Whitebark Pine (Pinus albicaulis) Forests in the West Big Hole Range of Idaho/Montana, U.S.A.
Potential Whitebark Pine range as calculated by regression analysis (Keane 2000).
Modeled frequency and predicted range of whitebark pine (Pinus albicaulis) under various climate scenarios
This dataset contains 8 layers showing current and predicted ranges of whitebark pine (Pinus albicaulis ). One layer demonstrates range according to current climate conditions averaged from the period 1950-1975. Six layers model predicted ranges according to two different IPCC scenarios according to their Canadian Climate Centre modeling and Analysis (CCCma) third generation general correlation models (CGCM3) A2 and B1, in the years 2020, 2050, and 2080. An 8th layer shows a continuous model of predicted occurrence for the period 1975-2006.
Combining state-and-transition simulations and species distribution models to anticipate the effects of climate change
Abstract (from http://www.aimspress.com/article/10.3934/environsci.2015.2.400): State-and-transition simulation models (STSMs) are known for their ability to explore the combined effects of multiple disturbances, ecological dynamics, and management actions on vegetation. However, integrating the additional impacts of climate change into STSMs remains a challenge. We address this challenge by combining an STSM with species distribution modeling (SDM). SDMs estimate the probability of occurrence of a given species based on observed presence and absence locations as well as environmental and climatic covariates. Thus, in order to account for changes in habitat suitability due to climate change, we used SDM to generate...
Our project provides evidence of the importance of climate for influencing recent and future mountain pine beetle outbreaks in whitebark pine forests. We recommend that land managers and decision makers consider the impacts of expected climate change on mountain pine beetle outbreaks in whitebark pine when planning conservation actions.
Use of sulfur and nitrogen stable isotopes to determine the importance of whitebark pine nuts to Yellowstone grizzly bears
Informing implementation of the Greater Yellowstone Coordinating Committee’s (GYCC) Whitebark Pine (WBP) Strategy based on climate sciences, ecological forecasting, and valuation of WBP-related ecosystem services Final Report
Managing plant and wildlife species under climate change offers a substantial challenge. Federal agencies have adapted a framework for considering climate change when implementing management actions. This project was designed to demonstrate how elements of that framework, climate science, ecological forecasting, and natural resource management, can be linked to best maintain natural resources under climate change. The project focused on the whitebark pine (WBP) tree. This species occupies high mountain forests and uniquely provides foods and habitats for other species. WBP populations have undergone massive die-offs over the past decade due to pest outbreaks associated with climate warming. In the Greater Yellowstone...
Funding supports a multiyear initiative entitled Crown of the Continent Landscapes Analysis/Ecological Indicators Project. The work is designed to focus on issues on transboundary data integration and synthesis, habitatconnectivity analysis for grizzly bears (Ursus arctos) and other key wildlife species, and outreach programs aimed at disseminating knowledge, information products, and geospatial tools arising out of this work to the extensive network of Crown Managers Partnership (CMP) and GNLCC collaborators.FY2010Objectives:The monitoring strategy will focus on the development and acquisition of geospatial datasets from remote sensing and other GIS sources designed to track changes in habitats and human footprint...
