Extreme heat and wildfire smoke events are increasingly co-occurring in the context of climate change, especially in California. Extreme heat and wildfire smoke may have synergistic effects on population health that vary over space.
On 7 September 2020, strong winds in western Oregon ignited and spread many small fires, leading to multiple simultaneous megafires (fires > 404 km2) that burned across multiple land ownerships. These fires burned at differing severities, resulting in a range of post-fire riparian and freshwater conditions and an opportunity to evaluate aquatic and riparian responses to fire across ownerships that vary in elevation, forest stand age, and forest-management strategies. To better understand these dynamics, the authors in this study measured riparian overstory survival, LW, and coarse wood (wood in riparian areas), as well as in-stream physical, chemical, and biological variables to fire severity and pre-fire stand age in 24 streams in western Oregon from 8-11 months following multiple fires, including the Riverside, Beachie, and Holiday Farm Fires.
Confluence is the Western Collaborative Conservation Network’s (WCCN) biennial gathering that provides an indispensable space for learning and professional community-building within the collaborative conservation field. For the complex, landscape-sca
This conference offers three essential tracks to ensure you and your team get everything you need in preparation to face the wildfire challenges ahead.
Tree regeneration is a critical mechanism of forest resilience to stand-replacing wildfire (i.e., where fire results in >90 % tree mortality), and post-fire regeneration is a concern worldwide as the climate becomes warmer.
Managing landscape fire is a complex challenge because it is simultaneously necessary for, and increasingly poses a risk to, societies and ecosystems worldwide. This challenge underscores the need for transformative change in the way societies live with and manage fire.
Fuel and restoration treatments seeking to mitigate the likelihood of uncharacteristic high-severity wildfires in forests with historically frequent, low-severity fire regimes are increasingly common, but long-term treatment effects on fuels, aboveground carbon, plant community structure, ecosystem resilience, and other ecosystem attributes are understudied.
Across western North America (WNA), 20th-21st century anthropogenic warming has increased the prevalence and severity of concurrent drought and heat events, also termed hot droughts. However, the lack of independent spatial reconstructions of both soil moisture and temperature limits the potential to identify these events in the past and to place them in a long-term context.
This work provides a detailed overview of existing investigations into the fire–wind interaction phenomena. Specifically, it considers: the fanning effect of wind, wind direction and slope angle, and the impact of wind on fire modelling, and the relevant analysis (numerical and experimental) techniques are evaluated. Recently, the impact of fire on buildings has been widely analysed.
