Fire Ecology & Effects
View article.
This study tested the stress-gradient hypothesis (SGH) in observations of 75 sites along overlapping water and heat stress and disturbance gradients. As stress-disturbance levels increase, sagebrush-herbaceous plant facilitation levels increase, the landscape will become increasingly aggregated as a product of necessary facilitation between sagebrush and herbaceous plants. This aggregation decreases the individual resilience of the native herbaceous plants, increases the competition from invasive plants, and decreases the overall stability and resilience of the sagebrush steppe ecosystem.

This final report includes actions to be implemented by Interior’s bureaus to immediately address the threat of rangeland fire and other disturbances to Western sagebrush-steppe landscapes and improve fire and fuels management efforts.
Access FEIS database.
The FEIS database provides access to more than 1,200 species reviews, 150 fire studies, and is now producing fire regime syntheses. This suite of products provides information on plant, lichen, and wildlife species’ life history, ecology, and relationship to fire and detailed descriptions of site characteristics, burning conditions, fire behavior, and fire effects. This spatially searchable database was developed by the USDA-FS, Rocky Mountain Research Station, Fire Sciences Laboratory, Missoula, Montana.

The initial report includes actions to be implemented by Interior’s bureaus to immediately address the threat of rangeland fire to Western sagebrush-steppe landscapes and improve fire management efforts before the start of the 2015 wildfire season.
View research brief.
This research brief summarizes research that found seed harvester ants, along with small mammals, could have a large impact on reseeding
efforts after a fire. But the populations over time are not well known. The number of ants in burned areas is significantly greater than unburned areas, but this may be an initial, short-lived response.
View the Order.
This Order sets forth enhanced policies and strategies for preventing and
suppressing rangeland fire and for restoring sagebrush landscapes impacted by fire across the West. These actions are essential for conserving habitat for the greater sage-grouse as well as other
wildlife species and economic activity, such as ranching and recreation, associated with the sagebrush-steppe ecosystem in the Great Basin region.

This Science article reports on a growing body of research challenging the widespread notion that beetle-killed forests are more vulnerable to more severe fires than those that have escaped infestation. The findings are highlighting the complex causes of western wildfires and raising new questions about the efficacy of some fire prevention policies, such as plans to remove beetle-killed trees from vast swaths of forest.

View fact sheet.
This fact sheet summarizes findings from a study comparing insect populations in burned and unburned areas. The study showed greater reproductive success for isolated plant survivors of generalist species, and less success for specialist species. The more specialized your reproductive strategy, the harder fire is on your sex life.
View brief.
This brief highlights a study following fire in Utah’s Rush Valley, where researchers found that fire killed biological soil crust pretty thoroughly, which wasn’t a surprise. However, following the fire cyanobacteria, the helpful and essential ingredient in biocrusts, did not return soon after fire, but Firmicutes, another tenacious and aggressive bacteria, did move in.
