Alaska has complex topography, with its extensive coastlines, dozens of islands, and mountain ranges that contain the tallest peaks in North America. Topography can have a strong influence on temperature and precipitation, therefore accurate representations of the terrain can improve the quality of simulations of past and future climate conditions. The spatial resolution of globally-available climate data is typically too coarse (~80 to 100 km) to adequately detect local landscape features, meaning these models aren’t useful for predicting future conditions in Alaska. In order for the state to adequately prepare for and adapt to changing conditions, high-resolution climate data is needed. One solution for acquiring...

Wildfires are a natural occurrence in interior Alaska’s boreal forest. There is extreme variability in the severity of the wildfire season in this region. A single year in which more than one million acres of forest burns can be followed by several years of low to moderate fire activity. In addition, fires in high latitude zones appear to be responding to changes in climate. Warmer temperatures rapidly cure understory fuels, such as fast-drying beds of mosses, lichens, and shrubs, which lie beneath highly flammable conifer trees. Managing such variability is challenging in light of both changing climate conditions and the fact that planning activities require sufficient advance warning. The goal of this project...

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...

The Yukon-Kuskokwim Delta (YKD) encompasses the southernmost, warmest parts of the arctic tundra biome and is renowned for its high biological productivity and large subsistence-based human population. Ice-rich permafrost currently is widespread and strongly influences terrestrial and aquatic habitats, including local topography, vegetation, soil hydrology, and the water balance of lakes. Ground temperatures are near the freezing point, however, and recent projections indicate that the YKD is poised for widespread loss of permafrost by the end of this century. This has implications for the region’s extensive and heretofore stable terrestrial and aquatic habitats. Tundra wildfire is a common ecological “pulse” disturbance...

Understanding freshwater flow is frequently highlighted as a priority in land management planning and assessments. Changes in climate can impact streamflow through reduced snowpack and snowfall, earlier spring runoff, increased winter flow and flooding, and decreased summer flow. In Southeast Alaska, streamflow is expected to shift dramatically in response to changes in factors such as precipitation and air temperature. Understanding how streamflow might change is instrumental not only for predicting changes in plant distribution and soil moisture, but also for infrastructure planning. Culvert replacement, bridge design, hydropower development, water reservoir placement, and floodplain restoration planning all require...
