Kristen’s work focuses on applying forest inventory information to inform management that will increases ecosystem resilience (the ability of a system to recover its characteristic functions) to natural and human-caused stressors. She has pursued research on how natural disturbances, current and past management practices, and climate change interact to affect forest structure and function in the interior western US.
Why This Research is Important
Land management that emulates natural disturbances is one of the best ways to ensure overall ecosystem health and the reliability of services valuable to society (such as water delivery, carbon sequestration, and forage production). Fire, bark beetles, and other disturbances affect components of landscapes across multiple scales in ways that are often important but not immediately obvious. In the past, when we have managed for one resource (such as timber production) at the expense of others we have often suppressed natural disturbances (such as fire) and there have been unintended negative consequences (such as increased homogeneity of forest conditions and susceptibility to growth of insect outbreaks).
Though we may know what disturbance types have shaped deserts, woodlands, and forests in the past, we often do not understand the sometimes subtle ways these disturbances vary with climate, topography, or species composition. We also do not fully understand how other stresses associated with climate change or invasive species will impact the recovery of systems following disturbance. Therefore it is critical to understand how disturbance scales, frequencies, and effects differ among landscapes and interact with on-the-ground conditions for management to avoid unintended consequences in the future.
