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 Davies et al. (2016) and relevant literatureprovides strong evidence that the comments of Smith et al.

An assessment of outcomes from research projects funded by the Joint Fire Science Program was conducted to determine whether or not science has been used to inform management and policy decisions and to explore factors that facilitate use of fire science.

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 bunchgrasses.

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 approach is demonstrated via a case study.

The hazards-of-place model posits that vulnerability to environmental hazards depends on both biophysical and social factors. Biophysical factors determine where wildfire potential is elevated, whereas social factors determine where and how people are affected by wildfire. We evaluated place vulnerability to wildfire hazards in the coterminous US.

Several aspects of wildland fire are moderated by site- and landscape-level vegetation changes caused by previous fire, thereby creating a dynamic where one fire exerts a regulatory control on subsequent fire. For example, wildland fire has been shown to regulate the size and severity of subsequent fire. However, wildland fire has the potential to influence other properties of subsequent fire.

Very large fires (VLFs) have important implications for communities, ecosystems, air quality and fire suppression expenditures. VLFs over the contiguous US have been strongly linked with meteorological and climatological variability.

The Monitoring Trends in Burn Severity project is a comprehensive fire atlas for the United States that includes perimeters and severity data for all fires greater than a particular size (~400 ha in the western US, and ~200 ha in the eastern US). Although the database was derived for management purposes, the scientific community has expressed interest in its research capacity.

An increase in mega-fires and wildfires is a global issue that is expected to become worse with climate change. Fuel treatments are often recommended to moderate behaviour and decrease severity of wildfires; however, the extensive nature of rangelands limits the use of many treatments.

Burn severity products created by the Monitoring Trends in Burn Severity (MTBS) project were used to analyse historical trends in burn severity.
