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…

Belowground bud bank regeneration is a successful strategy for plants in fire-prone communities. It depends on the number and location of dormant and viable buds stored on belowground organs. A highly diverse belowground bud-bearing organ system…
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:
Sagebrush ecosystems of western North America are threatened by invasive annual grasses and wildfires that can remove fire-intolerant shrubs for decades. Fuel reduction treatments are used ostensibly to aid in fire suppression, conserve wildlife…
Year Published:
Aim: Climate warming is expected to drive upward and poleward shifts at the leading edge of tree species ranges. Disturbance has the potential to accelerate these shifts by altering biotic and abiotic conditions, though this potential is likely to…
Year Published:
Wildfires in the western United States (US) are increasingly expensive, destructive, and deadly. Reducing wildfire losses is particularly challenging when fires frequently start on one land tenure and damage natural or developed assets on other…

Fire and rain: a systematic review of the impacts of wildfire and associated runoff on aquatic fauna
Climate and land-use changes are expected to increase the future occurrence of wildfires, with potentially devastating consequences for freshwater species and ecosystems. Wildfires that burn in close proximity to freshwater systems can significantly…
Year Published:
Many ecologically important high elevation five-needle white pine (HEFNP) forests that historically dominated upper subalpine landscapes of western North America are now being impacted by mountain pine beetle (Dendroctonus spp.) outbreaks, the…
Year Published:
Background: The structure and function of fire-prone ecosystems are influenced by many interacting processes that develop over varying time scales. Fire creates both instantaneous and long-term changes in vegetation (defined as live, dead, and…
Year Published:
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:
In fire-prone forests, postfire tree recovery may be limited by climate conditions and fire activity that exceed the range of conditions under which these forests evolved, leading to major shifts in forest structure and composition. Transformations…
Year Published:
Motivation: Rapid climate change is altering plant communities around the globe fundamentally. Despite progress in understanding how plants respond to these climate shifts, accumulating evidence suggests that disturbance could not only modify…
Year Published:
In ecosystems where trees and grasses coexist, some grass species are found only in open habitats and others persist under trees. The persistence of shade intolerant grasses in ecosystems such as open woodlands and savannas depends on recurrent…
Year Published:
As temperatures continue rising, the direction, magnitude, and tempo of change in disturbance-prone forests remain unresolved. Even forests long resilient to stand-replacing fire face uncertain futures, and efforts to project changes in forest…
Year Published:
Background: Fire is a multifaceted force. Fire activity and risk of fire incidence across US forested ecosystems have accelerated over the last two decades. At the same time, human land-use choices and climate change interacted with fire, in an era…

Fire is one of Earth's most potent agents of ecological change. This Special Issue comes in the wake of a series of extreme wildfires across the world, from the Amazon, to Siberia, California, Portugal, South Africa and eastern Australia (Duane et…
Year Published:
Fire refugia and patchiness are important to the persistence of fire-sensitive species and may facilitate biodiversity conservation in fire-dependent landscapes. Playing the role of ecosystem engineers, large herbivores alter vegetation structure…
Year Published:
Fire suppression and the loss of western white pine (WWP) have made northern Rocky Mountain moist mixed-conifer forests less disturbance resilient. Although managers are installing hundreds of plantations, most of these plantations have not…
Year Published:
Building fire-adaptive communities and fostering fire-resilient landscapes have become two of the main research strands of wildfire science that go beyond strictly biophysical viewpoints and call for the integration of complementary visions of…
Year Published:
Burn severity in forests is commonly assessed in the field with visual ordinal estimates such as the Composite Burn Index (CBI). However, how CBI (a composite of several individual field measures) relates to independent quantitative measures of burn…
