Wildfire is a cause of disturbance on public lands, and post-fire treatments often include broadcast seeding of native and non-native seeds. We collected vegetation data from an area burned by a wildfire in western Colorado in 2012 and, where…

The effectiveness of annual investments in US wildfire management programs has been subject to public criticism. One source of inefficiency may arise from a fragmented budgeting process. In the United States, federal budgets for wildfire management…

Wildfires are natural disturbances in the western United States. Managing the resulting stands of dead and dying trees requires balancing conflicting priorities. Although these trees provide wildlife habitat and salvage logging revenue, they also…

Smouldering fire vulnerability in organic-rich, wetland soils is regulated by hydrologic regimes over short (by antecedent wetness) and long (through influences on soil properties) timescales. An integrative understanding of these controls is needed…

(1) Background: Frequent fire, climate variability, and human activities collectively influence savanna ecosystems. The relative role of these three factors likely varies on interannual, decadal, and centennial timescales. Here, we tested if Euro-…

Forests store a large amount of terrestrial carbon, but this storage capacity is vulnerable to wildfire. Combustion, and subsequent tree mortality and soil erosion, can lead to increased carbon release and decreased carbon uptake. Previous work has…

Western juniper occurs in the Pacific Northwest, California, and Nevada. Old-growth western juniper stands that established in pre-settlement times (before the 1870s) occur primarily on sites of low productivity such as claypan soils, rimrock,…

Wildfires are often perceived as destructive disturbances, but we propose that when integrating evolutionary and socioecological factors, fires in most ecosystems can be understood as natural processes that provide a variety of benefits to humankind…

Before the advent of intensive forest management and fire suppression, western North American forests exhibited a naturally occurring resistance and resilience to wildfires and other disturbances. Resilience, which encompasses resistance, reflects…
