Indigenous stewardship rights and opportunities to recenter Indigenous fire
Year: 2025
Wild and intentionally ignited fires are not new to North American landscapes or to the Indigenous cultures whose ancestral places encompass them. For millennia, Indigenous fire stewardship has been regionally and locally distributed across North American ecosystems. These practices reshaped fire regimes to provide safe living and foraging conditions and reduced wildfires and their emissions prior to Euro-American colonization. Euro-American colonization impacts initially included introduction of foreign diseases and widespread genocide, which broadly diminished the extent of Indigenous fire…

Frequent, heterogenous fire supports a forest owl assemblage
Year: 2025
Fire shapes biodiversity in many forested ecosystems, but historical management practices and anthropogenic climate change have led to larger, more severe fires that threaten many animal species where such disturbances do not occur naturally. As predators, owls can play important ecological roles in biological communities, but how changing fire regimes affect individual species and species assemblages is largely unknown. Here, we examined the impact of fire severity, history, and configuration over the past 35 years on an assemblage of six forest owl species in the Sierra Nevada, California,…

Severity of a megafire reduced by interactions of wildland fire suppression operations and previous burns
Year: 2024
Burned area and proportion of high severity fire have been increasing in the western USA, and reducing wildfire severity with fuel treatments or other means is key for maintaining fire-prone dry forests and avoiding fire-catalyzed forest loss. Despite the unprecedented scope of firefighting operations in recent years, their contribution to patterns of wildfire severity is rarely quantified. Here we investigate how wildland fire suppression operations and past fire severity interacted to affect severity patterns of the northern third of the 374 000 ha Dixie Fire, the largest single fire in…
