Measuring ecosystem response to changing environments in Pacific Northwest forests
Scientists are combining satellite remote sensing and ground survey data to better understand the impacts of
Pacific Northwest forests are sensitive to temperature and
Aerial surveys and satellite remote sensing data are key to understanding the effects of important disturbance agents, primarily forest insects and fire, on the landscape scale. However, these methods generally fail to detect disturbances whose symptoms are sporadic in time and space, such as foliage disease; as a result, the role of some biotic disturbance agents has not been adequately addressed. Understanding biotic disturbances by forest type, and how they interact with climate conditions, is critical to predicting how forests will respond to future change and what the effects on ecosystem services will be.
Scientists from EPA and the USDA Forest Service are combining aircraft and satellite-based remote-sensing data with on-the-ground surveys to better understand the interacting effects of
