fuel treatment effectiveness

Background

Forest managers are faced with escalating size, severity, and cost of wildfires. To mitigate this, U.S. federal land management agencies are increasing forest treatments such as mechanical thinning and prescribed fire. While there is a growing body of work on treatment–wildfire interactions, treatment impacts in increasingly extreme wildfire situations remain unknown.

Managers across the western US seek effective fuel treatment strategies to mitigate hazardous fuel loads and risks of high severity fire in dry conifer forests. Conventional fuel hazard reduction treatments emphasis reducing canopy fuel continuity and surface fuel loading using an even spaced, thin-from-below approach, with pile or broadcast burning of residual surface fuels.

Wildfire activity has accelerated with climate change, sparking concerns about uncharacteristic impacts on mature and old-growth forests containing large trees.

Background. Fuel treatments are increasingly used to mitigate wildfire risks. 

Aims. Proposing a novel, scalable and transferable methodology, this study investigates which treatment is (more) effective at a regional scale.
