This study evaluated the effects of fire on biological soil crusts of early-seral juniper. Compared with unburned plots, the biomass of cyanobacteria was diminished under juniper and sagebrush; it was reduced in the interspaces in both burned and unburned plots, presumably in response to generally harsher conditions in the postburn environment. Nitrogen fixation rates declined over time in juniper plots and interspaces but not in sagebrush plots. Although fire negatively affected some biological soil crust organisms in some parts of the early-seral juniper woodland, the overall impact on the crusts was minimal. If the intent of burning is to reduce juniper, burning of early-seral juniper woodland is appropriate, as most affected trees were killed. Burning early-seral juniper may be preferred for controlling juniper encroachment on rangeland.

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 LANDFIRE tools.
LANDFIRE is a shared program between the wildland fire management programs of the USDA-FS and DOI, providing landscape scale geo-spatial products to support cross-boundary planning, management, and operations. It provides over 20 national geo-spatial layers (e.g. vegetation, fuel, disturbance, etc.), databases, and ecological models that are available to the public for the US and insular areas.

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 report.
This report outlines national and regional prescribed fire activity, state prescribed fire programs, and identifies impediments limiting the use of prescribed fire. The results include all federal, state, and private prescribed fire acres for forestry, rangeland, and agricultural burning that occurred in 2014.

This study evaluated how divergence from historic (pre-Euroamerican settlement) fire frequencies due to a century of fire suppression influences rates of high-severity fire in five forest types in California. With some variation, results suggest that fires in forest types characterized by fuel-limited fire regimes (e.g., yellow pine and mixed conifer forest) tend to burn with greater proportions of high-severity fire as either time since last fire or the mean modern fire return interval (FRI) increases.
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.
