View brief.
This research brief is based on several studies that can inform decision making by fire managers. Knowing that fire occurrence, size, and severity are limited by recent wildfires should provide greater flexibility and confidence in managing fire incidents and managing for resource benefit. Specifically, the findings from this study can be used by fire managers to help predict whether a previous fire will act as a fuel treatment based on fire age, forest type, and expected weather.

In this study, researchers determined vegetation response to fuel reduction by tree mastication (shredding) or seeding and then shredding by measuring cover of shrub and herbaceous functional groups on shredded and adjacent untreated areas on 44 sites in Utah. Findings suggested that shredding or seeding and then shredding should facilitate wildfire suppression, increase resistance to weed dominance, and lead toward greater resilience to disturbance by increasing perennial herbaceous cover.

This technical note provides a brief synopsis of proactive, linear fuel breaks as a tool for reducing negative impacts associated with large-scale wildfire in sagebrush ecosystems. The note summarizes what fuel breaks are designed to do, features of effective fuel breaks, specifications of common fuel break designs, and maintenance and management considerations based on a compilation of existing publications and practical lessons learned from past greenstrip and plant materials trials in the Great Basin. The purpose is primarily to provide practitioners with sufficient information to begin cooperative landscape planning efforts.

This study shows that conifer removal for sage-grouse also benefits sagebrush-dependent songbirds. In the Warner Mountains of southern Oregon, Brewer’s sparrow abundance increased by +55% and green-tailed towhee jumped +81% following cuts. Annual increases each year post tree removal suggest that songbird use may increase even more with time. Abundances of species less dependent on shrublands including mountain bluebird and rock wren were unaffected by treatments.

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.
