Woody debris export to large rivers following wildfire

February 2022 - September 2022


Participating Agencies

  • Alaska EPSCoR

Large woody debris (LWD) in Interior Alaska provides fish habitat and serves as a human fuel source while also posing a danger for river navigation and infrastructure. However, there is limited understanding of the extent to which wildfire may affect recruitment of LWD, especially into larger rivers. Because wildfire risk and frequency are increasing, understanding its impacts on LWD recruitment into rivers is becoming more important as a freshwater management concern. In this study I will quantify the magnitude of LWD export out of smaller streams into large rivers in Interior Alaska and explore how this recruitment is affected by wildfire. The results of this study will underscore how fish habitat and other factors associated with LWD may change as Interior Alaska experiences more wildfire.
