The current COVID-19 pandemic has demonstrated the vulnerability of healthcare systems worldwide. When combined with natural disasters, pandemics can further strain an already exhausted healthcare system. To date, frameworks for quantifying the…

Motivation. The World Health Organization declared COVID-19 a global pandemic on March 11, 2020 just as the southwestern region begins to see increased fire activity. The project PIs had been collaborating on other wildfire projects but also had…

This review summarizes information that was available in the scientific literature as of 2020 on the biology, ecology, and effects of fire and control methods on yellow starthistle in North America.
Yellow starthistle is a nonnative, invasive forb…

Violent fire-driven convection can manifest as towering pyrocumulus (pyroCu) or pyrocumulonimbus (pyroCb) clouds, which can have devastating impacts on the environment and society. Their associated fire spread is erratic, unpredictable and not…

We present an analysis of the spatio-temporal trends derived from long-term burned area (BA) data series. Two global BA products were included in our analysis, the FireCCI51 (2001-2019) and the FireCCILT11 (1982-2018) datasets. The former was…

A conceptual model based on the balance of energy in a system composed of a burning cigarette, ambient flow and a porous fuel bed is proposed to study the burning of a single cigarette and the process of fuel bed dehydration, pyrolysis and its…

Changing climatic conditions prompt concerns about vegetation response to disturbance under future compared to past conditions. In this long‐term study, we examined soil climate and vegetation differences at lower, mid, and upper elevations in two…

Grazing and fire are both independently important drivers of plant community dynamics; however, their interactive effects may be even more influential. Little is known about prefire grazing effects on postfire plant community dynamics. We…

Anthropogenic climate change is expected to cause an increase in fire danger over south-eastern Australia during the 21st century, primarily driven by increased surface temperature. Studies of future fire weather in Victoria, Australia, have so far…

The fire plume height (smoke injection height) is an important parameter for calculating the transport and lifetime of smoke particles, which can significantly affect regional and global air quality and atmospheric radiation budget. To develop an…

Improving the accuracy of fire behavior prediction requires better understanding of live fuel, the dominant component of tree crowns, which dictates the consumption and energy release of the crown fire flame-front. Live fuel flammability is not well…

Increasingly, scholars have sought to understand the role of collective action across property boundaries to address natural resource management challenges. Although the growing focus on collective action for natural resource management has led to…

The 2001 Forest Service Roadless Rule prohibits roadbuilding in forests across an area equivalent to the combined states of New York and Maine (236 000 km2). There have been recent assertions that roads are needed to prevent fire and to keep forests…

Seeding an area after a fire has long been used to control erosion and suppress problem invasive grasses like cheatgrass. But for managers, choosing the right seed mix to use can be tricky. Seed mixes containing only native species are ideal for…

To better understand the implications of the word resilience for western forest and fire management, this study explores its emerging use in a large body of policy and management documents produced between 1980 and 2016. We performed a computer-…

With increasing heat and droughts world-wide, wildfires are becoming a more serious global threat to the world’s population. Wildfire smoke is composed of approximately 80% to 90% of fine (<2.5 um) and ultrafine (<1 um) particulate matter (PM…

Stand-replacing fires burned at 100 to 300-year intervals for millennia in subalpine conifer forests of western North America, but forests are burning more frequently as climate warms. Postfire tree regeneration is reduced when young forests reburn…

The present study aimed to determine moisture thresholds for combustion of organic soils sampled from various vegetation types at 63 locations in Tasmania, Australia. To observe whether the soil sample sustained smouldering combustion, moisture…

The extent of severely burned landscapes are increasing in the Western US due to climate change and altered forest states. Directly after a wildfire, managers implement techniques to stabilize soils or harvest merchantable timber. Collaborating with…

Context: Distance to seed source is often used to estimate seed dispersal—a process needed for post-fire tree recovery. However, distance, especially in mountainous terrain, does not capture pattern or scale-dependent effects controlling seed supply…
