Abstract (from Forests): Research Highlights: Flammability of wildland fuels is a key factor influencing risk-based decisions related to preparedness, response, and safety in Alaska. However, without effective measures of current and expected flammability, the expected likelihood of active and problematic wildfires in the future is difficult to assess and prepare for. This study evaluates the effectiveness of diverse indices to capture high-risk fires. Indicators of drought and atmospheric drivers are assessed along with the operational Canadian Forest Fire Danger Rating System (CFFDRS). Background and Objectives: In this study, 13 different indicators of atmospheric conditions, fuel moisture, and flammability are...

In the last decade, the annual area burned by wildfires in Alaska has doubled relative to any of the previous four decades, and the current frequency of fire is unprecedented over the past 1,200 years. Wildland fires are one of the main contributors to long-term changes in the structure and function of boreal and subarctic ecosystems. Although fire is a necessary component of regulating these ecosystems, it also poses a hazard to humans when uncontrolled. Currently, fire managers use the Fire Behavior Prediction Calculator to perform calculations that can assist in field management of fires, but the only version of this tool that is available depends on network access, which poses a significant limitation for...

Alaska is an ecologically, commercially, and recreationally diverse state, providing value to people and terrestrial and aquatic species alike. Presently, Alaska is experiencing climatic change faster than any other area of the United States, but across the state, comprehensive environmental monitoring is logistically difficult and expensive. For instance, only about 1% of U.S Geological Survey (USGS) stream gages are in Alaska, and only about 50% of those gages measure water temperature, an important climate change indicator. In this study, predictive models are being used to map stream temperatures under current and future climate scenarios across the Yukon and Kuskokwim River basins (YKRB) at the stream reach...
