Background: Remotely sensed burned area products are critical to support fire modelling, policy, and management but often require further processing before use.
Aim: We calculated fire history metrics from the Landsat Burned Area Product (1984-2020…

As 21st-century climate and fire activity depart from historical baselines, effects on
forests are uncertain. Forest managers need to predict and monitor forest recovery and fuel
accumulation to anticipate future fire behavior and plan appropriate…
Year Published:
Invasive grass species can alter fire regimes, converting native terrestrial ecosystems into non-native, grass-dominated landscapes, creating a self-reinforcing cycle of increasing fire activity and flammable grass expansion. Analyses of this…

We investigated the relative importance of daily fire weather, landscape position, climate, recent forest and fuels management, and fire history to explaining patterns of remotely-sensed burn severity – as measured by the Relativized Burn Ratio – in…

Ancient giant sequoias Sequoiadendron giganteum (Lindl.) J. Buchholz are highly valued trees with limited distribution. They are the most massive trees on earth, and they have exceptional longevity (>3,000 years). Given their extraordinary…

Protected areas are essential to conserving biodiversity, yet changing climatic conditions challenge their efficacy. For example, novel and disappearing climates within the protected area network indicate that extant species may not have suitable…

In the western US, wildfires are modifying the structure, composition, and patterns of forested landscapes at rates that far exceed mechanical thinning and prescribed fire treatments. There are conflicting narratives as to whether these wildfires…

Analyses of the effects of topography, weather, land management, and fuel on fire severity are increasingly common, and generally apply fire severity indices derived from satellite optical remote sensing. However, these indices are commonly…
Year Published:
Acting as a top-down control on fire activity, climate strongly affects wildfire in North American ecosystems through fuel moisture and ignitions. Departures from historical fire regimes due to climate change have significant implications for the…
Year Published:
Recent increases in fire frequency and severity across the western US are triggering abrupt changes in ecosystem structure and composition, especially in lower montane forests, but consequences of fire-regime change for mesic, mixed-conifer forests…
Year Published:
In fire-dependent forest landscapes, frequent low- to moderate-severity fire maintained vegetation patterns that limited the severity of droughts, wildfires, and insect and pathogen activity. More than a century of fire exclusion, in combination…
Year Published:
Fire regimes shape plant communities but are shifting with changing climate. More frequent fires of increasing intensity are burning across a broader range of seasons. Despite this, impacts that changes in fire season have on plant populations, or…
Year Published:
Fire behavior and intensity vary within and between fires, mediated by factors such as slope, aspect, elevation, fuel loading and vegetation type. These influences create a mosaic of burn severity, shaping forests around the world. These burn…

With the increasing frequency and severity of altered disturbance regimes in dry, western U.S. forests, treatments promoting resilience have become a management objective but have been difficult to define or operationalize. Many reconstruction…
Year Published:
Natural disturbances serve as a driver of change, creating complexity and heterogeneity across the landscape. Ecological patterns and processes that arise from the impacts of disturbance determine the plant and animal species a landscape supports…
