Topic: Fire Effects and Fire Ecology

Changes in the climate and in key ecological processes are prompting increased debate about ecological restoration and other interventions in wilderness. The prospect of intervention in wilderness raises legal, scientific, and values-based questions about the appropriateness of possible actions…

The environmental effect of extreme soil heating, such as occurs with the complete combustion of large downed wood during wildfires, is a post-fire management concern to forest managers. To address this knowledge gap, we stacked logs to create ‘mega-log’ burning conditions and compared the…

This study presents an alternative approach to developing severity assessments. A synthesis of challenges using current approaches is presented. The proposed approach links heat transfer dose–response experimental treatments with plant physiology response metrics. The potential of this new…

A recent study by Davies et al. sought to test whether winter grazing could reduce wildfire size, fire behaviourand intensity metrics, and fire-induced plant mortality in shrub–grasslands. The authors concluded that ungrazedrangelands may experience fire-induced mortality of native perennial…

A recent commentary by Smith et al. (2016) argues that our study (Davies et al. 2016) containedmethodological errors and lacked data necessary to support our conclusions, in particular that winter grazing may reducethe probability of fire-induced mortality of bunchgrasses. Carefully reading…

We present a case study of the Las Conchas Fire (2011) to explore the role of previously burned areas (wildfires and prescribed fires) on suppression effectiveness and avoided exposure. Methodological innovations include characterisation of the joint dynamics of fire growth and suppression…

Morel mushrooms are globally distributed, socially and economically important reproductive structures produced by fungi of the genus Morchella. Morels are highly prized edible mushrooms and significant harvests are collected throughout their range, especially in the first year after fire, when…

Many recent wildfires in ponderosa pine (Pinus ponderosa Lawson & C. Lawson) - dominated forests of the western United States have burned more severely than historical ones, generating concern about forest resilience. This concern stems from uncertainty about the ability of ponderosa pine…

As wildland fire activity continues to surge across the western US, it is increasingly important that we understand and quantify the environmental drivers of fire and how they vary across ecosystems. At daily to annual timescales, weather, fuels, and topography are known to influence…

Understanding the causes and consequences of rapid environmental change is an essential scientific frontier, particularly given the threat of climate- and land use-induced changes in disturbance regimes. In western North America, recent widespread insect outbreaks and wildfires have sparked…
