The authors argue that over a century of fire exclusion has replaced historical, fire-resilient mosaics with dense, fuel-heavy landscapes that are increasingly vulnerable to high-severity, stand-replacing fires. To address this crisis, the authors advocate for a shift from aggressive suppression toward proactive management, including the strategic use of mechanical thinning and prescribed burning. This resource evaluates ten common questions that often cause public or scientific disagreement, such as the efficacy of treatments under extreme fire weather and the necessity of managing forests beyond the wildland urban interface. -
The Use of Silviculture and Prescribed Fire to Manage Stand Structure and Fuel Profiles in a Multi-aged Lodgepole Pine Forest
This case study evaluates how different logging and fire management techniques can simulate natural disturbance patterns in Montana's lodgepole pine forests. The authors compared two specific shelterwood silvicultural treatments: one where remaining ...This case study evaluates how different logging and fire management techniques can simulate natural disturbance patterns in Montana's lodgepole pine forests. The authors compared two specific shelterwood silvicultural treatments: one where remaining trees were spread out evenly, and another where they were kept in concentrated groups. The study found that prescribed burning effectively reduced the hazardous fine-fuel loading created by harvesting and the even distribution method led to much higher levels of unintentional tree mortality than the grouped approach. The authors suggest that grouped retention may be a more resilient strategy for restoring forest structure because it better protects delicate overstory trees from both fire damage and windthrow. -
Assessing Post-Fire Douglas-fir Mortality and Douglas-fir Beetle Attacks in the Northern Rocky Mountains
This report presents models to predict the likelihood of Douglas-fir mortality and bark beetle infestation following wildfires.

The authors developed these tools using data from past fires in Montana and Wyoming, aiming to improve both pre-fire planning and post-fire management decisions. The report details the significant variables influencing tree survival and beetle attacks, such as crown scorch and cambium damage, and includes a supplementary field guide with visual aids and methods for field data collection, providing a practical resource for forest managers.
