Wildfire-initiated dead wood legacies: Post-fire habitat and fuels trajectories in westside Pacific Northwest forests, USA
Year: 2025
Managers grappling with questions about dead wood in productive, often high-volume, westside Pacific Northwest forests seek to balance wildlife habitat quality and fire hazard reduction, especially following wildfires which can both consume and generate exceptional quantities of dead wood. Longitudinal analysis of a large (n = 327) sample of permanent forest inventory monitoring plots measured before and repeatedly after wildfires and an equal-sized sample of comparable but unburned reference plots revealed post-fire trajectories of dead wood and factors that drive abundance of snags, litter…

Wildfire recovery in Pacific Northwest Latine communities: how community capitals shape disaster resilience
Year: 2025
Wildfires are increasingly affecting people’s lives in the Pacific Northwest. Latine populations, in particular, often face unique challenges in their recovery process. This study examines individual Latine wildfire recovery experiences to understand the strengths and barriers in the community’s post-fire recovery process in two wildfire-affected areas in Oregon and Washington. Perceptions of recovery of Latine community members and community-based organizations that serve these populations were collected through focus groups, semi-structured interviews, and participant observation at…

A post-fire reforestation assessment and prioritization tool for the Western United States
Year: 2025
BackgroundIncreasing wildfire area burned has left millions of hectares in the western United States (US) in need of reforestation. Recent federal legislation allows for increased investments in tree planting to address the backlog of planting needs in previously burned areas. To support post-fire planning and assessment, we developed Regenmapper, a web-based decision support system (DSS) that provides spatial information on natural regeneration potential within post-fire environments. The program is freely available from a web browser (…

Initial Divergent Postfire Recovery Converges Over the Long-term: A Case Study in Juniper-Encroached Sagebrush Steppe
Year: 2025
Reduced fire frequency is recognized as a main cause of piñon–juniper (Pinus–Juniperus L.) expansion in western North American sagebrush steppe and grasslands. Piñon–juniper woodland control using prescribed fire and mechanical treatments have increased the past three decades with the goal of restoring sagebrush steppe plant communities. Factors shaping the response of sagebrush steppe communities following woodland treatment include shrub and herbaceous composition, level of tree dominance, and site characteristics. We compared vegetation recovery spanning 20 yr following prescribed…

Insights from a 25-year database of post-fire debris flows in California
Year: 2025
BackgroundPost-wildfire debris flows (PFDFs) frequently threaten life, property and infrastructure in California. To date, there is no comprehensive assessment of their spatial distribution, seasonality, atmospheric drivers and interannual variability across the state.AimsWe develop a database of PFDF events in California for the period 2000–2024 and analyze the database to describe spatial and temporal variability and impacts of PFDFs.MethodsWe use peer-reviewed literature, media and agency reports to compile the PFDF event database and…

Long-term soil nutrient and understory plant responses to post-fire rehabilitation in a lodgepole pine forest
Year: 2025
Wildfires and other disturbances play a fundamental role in regenerating lodgepole pine forests. Though severe, stand-replacing fires are typical of this ecosystem, they can have dramatic impacts on soil properties and biogeochemical processes that influence the rate and composition of vegetation recovery. Organic soil amendments are often applied to manage post-fire erosion, but they can also improve soil moisture and nutrient retention and potentially alter the trajectory of post-fire revegetation. We compared change in soil nutrients, microbial communities, and understory plant cover and…

Complexities in post-wildfire governance: lessons from Colorado’s 2020 wildfires
Year: 2025
Background: The increasing size and severity of western U.S. wildfires in recent years has generated greater attention towards post-wildfire response and recovery. Post-fire governance requires coordinating response and recovery capacities across jurisdictions, landscapes, and time scales. The presence of wildfire on federal public lands necessitates federal agency involvement in both suppression and recovery efforts, and program coordination with lower levels of government and non-governmental organizations. Using semi-structured interviews, we investigated experiences of leaders across the…
