This field guide provides substantial evidence that pinon-juniper woodlands have experienced major expansion in their distribution since the late 1800s by encroaching into surrounding landscapes once dominated by shrubs and herbaceous vegetation. Both infilling and expansion affects soil resources, plant community structure and composition, water and nutrient cycles, forage production, wildlife habitat, biodiversity, and fire patterns across the landscape. Another impact is the shift from historic fire regimes to larger and more intense wildfires that are increasingly determining the future of this landscape.

This field guide identifies seven primary components that largely determine resilience to disturbance, as well as resistance to invasive grasses and plant succession following treatment of areas of concern. An evaluation score sheet is included for rating resilience to disturbance and resistance to invasive annual grasses and the probability of seeding success.

This guide assimilates post-treatment vegetation and fuels data from Sagebrush Steppe Treatment Evaluation Project (SageSTEP) study sites across six Great Basin states into an assessment tool that can help managers better estimate percent cover, stem density and fuel loadings for post-treatment sites. The post-treatment Guide uses photographs and tables to provide the range of values for each vegetation type allowing users to quickly appraise a site by fuel stratum using an ocular estimate.

This guide features 40 bird species that utilize sagebrush habitats and includes tips on species identification, biology, and conservation status. Because not all of these species require similar habitat types and not all sagebrush is managed for the same goals, this guide discusses how avian needs can be incorporated into land management plans.

Around the world, woodlands and forests are replacing native grasslands and shrublands which impacts wildlife and people. In the sagebrush biome of the American West, pinyon pine, juniper, and other native conifer trees are expanding into imperiled shrublands. Learn more about the implications of this woodland encroachment and what communities are doing to restore healthy and resilient shrublands.

In the winter and spring of 2022, the National Forest Foundation (NFF), in coordination with the USDA Forest Service, hosted a series of roundtables across the country to gather input on the Wildfire Crisis Strategy Implementation Plan. The NFF distilled these productive discussions with Forest Service employees and partners into regional reports and an overall synthesis report, available at nationalforests.org/wildfire-roundtables.
The purpose of this webinar is to share more information about the report, discuss next steps, and provide an opportunity for Q&A with Forest Service leadership.

Five ethical lenses were generated from the thematic coding process: Epistemologies and Representation, Values and Priorities, Risk and Uncertainty, Power, and Metaethics. The five lenses provide a framework to identify prospective ethical tensions in wildland fire decision-making, both within and cutting across categories. This framework provides a way of structuring future investigations into wildfire ethics, as well as a starting point for developing techniques to integrate community and stakeholder values.

A slight, gradual decline in total C and N was found with increasing temperature and heat duration, reaching a maximum loss of 14–18% of the total at the highest heat load. Available NH4 increased linearly starting at 150–175 °C and reached a maximum 15-fold increase relative to unburned soil by 450 °C. Nitrification (30-d post-fire) was low regardless of treatment and was essentially eliminated at the highest temperatures. Microbial biomass declined curvilinearly with increased heating, approaching 65% loss compared to unburned soil, and was most rapid in moist soil once temperatures exceeded 60–70 °C. Ultimately, we found no evidence of abrupt heat thresholds for these common soil properties. Instead, property changes followed a slightly declining trajectory (soil C, N, NO3, fungal hyphae) or a steady incremental increase (NH4) or decrease (microbial biomass).
