Development of a Severe Fire Potential map for the contiguous United States

Publications Posted on: August 17, 2020
Burn severity is the ecological change resulting from wildland fires. It is often mapped by using prefire and postfire satellite imagery and classified as low, moderate, or high. Areas burned with high severity are of particular concern to land managers and others because postfire vegetation, soil, and other important ecosystem components can be highly altered.

Creosote growth rate and reproduction increase in postfire environments

Publications Posted on: August 16, 2020
Human activities are changing patterns of ecological disturbance globally. In North American deserts, wildfire is increasing in size and frequency due to fuel characteristics of invasive annual grasses. Fire reduces the abundance and cover of native vegetation in desert ecosystems.

Fire and land cover change in the Palouse Prairie-forest ecotone, Washington and Idaho, USA

Publications Posted on: August 10, 2020
Prairie-forest ecotones are ecologically important for biodiversity and ecological processes. While these ecotones cover small areas, their sharp gradients in land cover promote rich ecological interaction and high conservation value. Our objective was to understand how historical and current fire occurrences and human development influenced the Palouse Prairie-forest ecotone.

Natural fuels

Publications Posted on: August 10, 2020
Wildland fuelbeds are diverse collections of biomass categorized specifically to compute fire behavior and effects. When wildland fuelbeds are created by solely “natural” processes, fire scientists, and managers often refer to these as natural fuels (Fig. 1). NWCG (2018) defines natural fuels as fuels resulting from natural processes and not directly generated or altered by land management practices.

Historical range and variation (HRV)

Publications Posted on: August 10, 2020
Many ecosystems and landscapes are experiencing rapid and potentially persistent changes as the result of complex and potentially novel interactions of anthropogenic climate changes; shifting fire regimes; exotic plant, insect, and pathogen invasions; and industrial, agricultural, and urban development (Moritz and Agudo 2013; Joyce et al. 2014; Bone et al. 2016; Kolb et al. 2016; Smith et al. 2016; Stephens et al. 2016; Schoennagel et al.

Fire ecology

Publications Posted on: August 10, 2020
Wildland fire is perhaps the most influential disturbance over vast areas in the modern world (Bowman et al. 2009). Fire is both a natural and anthropogenic disturbance influencing the distribution, structure, and functioning of terrestrial ecosystems around the world (Bond et al. 2005; Scott et al. 2014).

Post-fire tree mortality

Publications Posted on: August 10, 2020
By killing trees, wildland fires influence ecosystems in many ways, including limiting ecosystem productivity, altering resource availability, and changing the structure and composition of vegetation (Bond and Keeley 2005). These changes can have both positive and negative impacts on carbon storage, biodiversity conservation, hydrologic processes, and economic and social services (Bowman et al. 2009).

Fire and bark beetle interactions

Publications Posted on: August 10, 2020
Wildland fire and bark beetle outbreaks are both large disturbances in North American forests with the potential to interact over spatial and temporal scales (Hicke et al. 2016; Raffa et al. 2008). The order of the disturbances, fire before bark beetles or fire after bark beetles, influences the outcome of the interaction.

Rethinking resilience to wildfire

Publications Posted on: August 22, 2019
Record-breaking fire seasons are becoming increasingly common worldwide, and large wildfires are having extraordinary impacts on people and property, despite years of investments to support social-ecological resilience to wildfires.

Tree-ring-based reconstructions of historical fire regimes for quaking aspen, Great Basin bristlecone pine and mountain sagebrush communities

Projects Posted on: August 07, 2019
Tree-ring based fire histories from Utah and Nevada reveal multi-century fire patterns for quaking aspen, mountain sagebrush and Great Basin bristlecone pine communities.
