Changing fire regimes in the Great Basin USA
Year: 2025
Wildfire is a natural disturbance in landscapes of the Western United States, but the effects and extents of fire are changing. Differences between historical and contemporary fire regimes can help identify reasons for observed changes in landscape composition. People living and working in the Great Basin, USA, are observing altered fire conditions, but spatial information about the degree and direction of change and departure from historical fire regimes is lacking. This study estimates how fire regimes have changed in the major Great Basin vegetation types over the past 60 years with…

Combining ecophysiology and combustion traits to predict conifer live fuel moisture content: a pyro-ecophysiological approach
Year: 2025
Background Fuel moisture content is a key driver of fuel flammability and subsequent fire activity and behavior worldwide. Dead fuels passively exchange moisture with the atmosphere while live fuel moisture is confounded by a mixture of seasonal carbon and water cycle dynamics. Despite the significance of live fuel moisture content (LFMC) on wildland fire potential, attempts to model its variations seasonally and between species are often inconclusive or unsuccessful.ResultsHere we present a mechanistic LFMC model that uses easily measured live fuel…
