Research Highlights
The new normal: empirical estimates of future fire environments in the Pacific Northwest
Year: 2018
If the climate continues to change as predicted, large wildfires are expected to become more common in portions of the Pacific Northwest. A set of time series maps provides empirical estimates of how climate change might affect the geographic distribution of large wildfires and fire rotations in the...
Maps of biomass dynamics support North American Carbon Program
Year: 2011
Forest Service scientists and collaborators modeled live, aboveground tree biomass by using Forest Inventory and Analysis field data and applied the models to more than 20 years of Landsat satellite imagery to derive trajectories of aboveground forest biomass for study locations across the continent...
Maps illustrate 23 years of change on Northwest forests
Year: 2010
By using historical remote-sensing data, researchers developed maps of annual forest change between 1984 and 2007. These maps, with a resolution of 98 feet (30 meters), of western Oregon, western Washington, and northern California show changes from timber harvests (thinnings to clearcuts), fires (l...
