Climate change is causing an increase in the amount of forested area burned by wildfires in the western U.S. The warm, dry post-fire conditions of the region may limit tree regeneration in some areas, potentially causing a shift to non-forest vegetation. Managers are increasingly challenged by the combined impacts of greater wildfire activity, the significant uncertainty about whether forests will recover, and limited resources for reforestation efforts. Simultaneously, there has been an increased focus on post-fire reforestation efforts as tree planting has become a popular climate change mitigation strategy across the nation. Therefore, with increased interest and need, it is crucial to identify where varying...

FY2013This project retrieves four years of data from over 200 temperature sensors nested within 28 sites across ~40 million hectares of the hydrographic Great Basin. The sensors span all major aspects and up to 700 m of elevation within sites, and occur in numerous management jurisdictions in 18 mountain ranges plus other areas not in ranges. This project: Quantifies the variability of climate at micro-, meso-, and macroscales across the Basin, and across diel, seasonal, and interannual periods. Informs management and conservation efforts, in terms of helping calibrate and refine the climatic stage upon which all biological actors and efforts hinge (Beier and Brost 2010). Feeds into other bioclimatic and wildlife...

In the Northern Rockies, the annual area burned by wildfires has risen sharply in recent decades and is expected to continue growing. As a result, burned forests increasingly comprise a significant portion of the land base. However, burned areas represent a difficult paradox for land managers, especially in the context of other climate-linked disturbances (e.g., droughts, bark beetle outbreaks) that are also on the rise and may compound initial fire-induced stressors. While, burned areas have experienced major recent changes that may decrease their resilience to subsequent, compounding stressors, fire-induced changes can also lead to longer-term increases in resilience. The evolving landscape conditions triggered...

The Northwest Climate Adaptation Science Center (NW CASC) advances actionable science relevant to today’s emerging climate-related risks by supporting research by early-career NW CASC Fellows. The NW CASC’s Research Fellowship Program enables graduate students and postdocs from a variety of scientific backgrounds to co-produce actionable science in collaboration with regional natural resource managers and decision-makers. Fellows receive support for research aligned with the NW CASC Science Agenda, as well as instruction in the principles and practices of co-production of decision-relevant, or actionable, science. The NW CASC University Consortium’s Research Fellowship Program supports climate adaptation research...

As wildfire activity surges in the western U.S., managers are increasingly challenged by decisions surrounding managing post-fire environments.Changing fire regimes and warmer,drier post-fire conditions are increasing the likelihood of post-fire vegetation transitions, for example,from forest to grassland. Given the economic and ecological importance of these ecosystems, transformation is a concern for managers, policy-makers, and the public. As rapid environmental changes occur, management aimed at maintaining historical conditions will become increasingly untenable, requiring managers to make decisions that steward vegetation toward desired or novel conditions. The Resist-Accept-Direct (RAD) framework provides...

Climate change is altering the patterns and characteristics of fire across natural systems in the United States. Resource managers in the Northwest are faced with making natural resource and fire management decisions now, despite a lack of accessible information about how those decisions will play out as fire regimes, and ecosystem responses, will change across the landscape. Decision makers in natural-resource management increasingly require information about projected future changes in fire regimes to effectively prepare for and adapt to climate change impacts. An accessible and forward-looking summary of what we know about the “future of fire” is urgently required in the Northwest and across the country to support...

Forests in the western U.S. are increasingly impacted by climate change. Warmer and drier conditions both increase fire activity in western forests and make it more difficult for forests to recover after wildfires. If forests fail to recover, they may shift to non-forest ecosystems like grasslands or shrublands. It is important to understand where fires may result in the loss of forests because forests provide a variety of ecosystem services that human communities rely on, including carbon storage, water regulation and supply, and biodiversity. Western forests are also integral for the timber industry and valued for their recreation opportunities. Anticipating future changes to forest ecosystems, particularly at...

The Northwest Climate Adaptation Science Center (NW CASC) delivers science to help fish, wildlife, water, land and people adapt to a changing climate. The NW CASC is hosted by the University of Washington in partnership with Boise State University, Oregon State University, the University of Montana, Washington State University, and Western Washington University. The NW CASC university consortium is designed to support coproduction of actionable science through all stages of the climate adaptation cycle, including awareness raising, risk assessment, and selection, implementation, monitoring and evaluation of response options. Research efforts focus on the science research themes outlined in the NW CASC’s 2018-2023...

Managing species and habitat in a changing climate requires locally specific information about expected changes in the physical environment, key stressors and related ecological changes. Federal investments have supported the development of a significant scientific knowledge base detailing potential future conditions for many Northwest ecosystem types and geographies. Yet scientists, managers and other decision makers continue to be challenged by the difficulty of efficiently assessing the current state of understanding regarding both impacts and pathways for adaptation. For example, while the most recent Washington and Oregon State Wildlife Action Plans included detailed consideration of climate change-related...
Abstract (from http://onlinelibrary.wiley.com/doi/10.1002/2014GL062803/abstract): Observations from the main mountain climate station network in the western United States (U.S.) suggest that higher elevations are warming faster than lower elevations. This has led to the assumption that elevation-dependent warming is prevalent throughout the region with impacts to water resources and ecosystem services. Here we critically evaluate this network's temperature observations and show that extreme warming observed at higher elevations is the result of systematic artifacts and not climatic conditions. With artifacts removed, the network's 1991–2012 minimum temperature trend decreases from +1.16°C decade−1 to +0.106°C decade−1...
