Metrics and Considerations for Evaluating How Forest Treatments Alter Wildfire Behavior and Effects Open
The influence of forest treatments on wildfire effects is challenging to interpret. This is, in part, because the impact forest treatments have on wildfire can be slight and variable across many factors. Effectiveness of a treatment also d…
