Science and Products
USGS WERC's Dr. Phil van Mantgem and his collaborators are using plot-based methods to describe change and vulnerability to drought in the forests of the western United States. A focus of this work is the installation and maintenance of large (1 ha) monitoring plots. Many other vegetation monitoring strategies are based on small (0.1 ha) plots, which may not be sufficient to detect changes in...
This project uses new and existing field data to assess forest restoration treatment effects across broad spatial and temporal scales. WERC's Dr. Phil van Mantgem and project partners are considering the effects of restoration treatments in terms of forest structure, forest stand development, subsequent tree mortality patterns mortality, and how climate influences the success or failure of...
How will increased drought affect forest fire severity? WERC’s Dr. Phil van Mantgem is testing the idea increased drought stress may affect forest fire severity independent of fire intensity. Drought stress prior to fire can affect tree health, potentially resulting in a higher sensitivity to fire-induced damage. Thus, with drought there may be ongoing increases in fire severity (the number of...
- Tree death rates have more than doubled over the last few decades in old-growth forests of our western states, possibly reflecting increasing temperatures, with potentially serious consequences for wildlife, fire risks, and the global carbon cycle
- Rising regional temperatures have lengthened the summer drought, likely stressing trees and leading to higher death rates
- Is this alarming trend a harbinger of larger, more abrupt changes in our forests?
