Anticipating Forest Vulnerability to Fire-Catalyzed Ecosystem Change in the Northern Rocky Mountains Completed
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 local scales relevant to land and resource managers, requires an understanding of the vulnerability of forests to fire-catalyzed change. The main goal of this work is to create a vulnerability assessment that highlights geographic areas and forest types most vulnerable to fire-catalyzed ecosystem change under current and future climate change scenarios. Researchers will assess the different parts of forest vulnerability, including exposure to varying elements of climate change (e.g. temperature and moisture balance), exposure to varying types of fires (e.g. high vs. low severity fire), and sensitivity of post-fire seedlings to climate-related mortality (e.g. through water stress).
Previous research findings on this topic, funded by the Joint Fire Science Program, the National Science Foundation, and NASA, are directly relevant to land managers, but require “translation” into practical and usable tools and resources. This project will rely on and strengthen communications and collaborations between researchers and federal land managers from the U.S. Forest Service and U.S. Department of the Interior bureaus through face-to-face interactions to ensure that managers have access to the science in a form that is useful. The proposed vulnerability assessment will help managers anticipate when and where wildfires will impact ecosystems in new ways, potentially causing ecosystem shifts from forested to non-forested areas, or to fundamentally different forest types.
