This report outlines a range-wide strategy for maintaining whitebark pine populations in high mountain areas based on the most current knowledge of the efficacy of techniques and differences in their application across communities. The strategy is written as a general guide for planning, designing, implementing, and evaluating fine-scale restoration activities for whitebark pine by public land management agencies, and to encourage agency and inter-agency coordination for greater efficiency. The strategy is organized into six scales of implementation, and each scale is described by assessment factors, restoration techniques, management concerns, and examples.

This review suggests that when applied, both prescribed fire and its mechanical surrogates are generally successful in meeting short-term
fuel-reduction objectives and in changing stand structure and fuel beds such that treated stands are more resistant and resilient to high-intensity wildfire.

This guide was written for anyone interested in learning more about sagebrush species and habitats. It provides descriptions of some of the remarkably diverse sagebrush communities in western North America. It gives identifying characteristics and range maps of 18 species of sagebrush.

This study reviewed and synthesized the published literature on modifications to fuels and fire characteristics following beetle-caused tree mortality. The literature agreed about responses in many conditions, including fuels measurements and changes in stands with longer times since outbreak. Disagreement or gaps in knowledge existed in several conditions, particularly in early post outbreak phases and crown fire behavior responses.

This study discusses the potential of a fungus naturally associated with these Bromus species, which is lethal to the plants’ soil-banked dormant seeds. Study findings open the way to a commercial biocontrol product that may be capable of safely eliminating the seed bank of persistent invasive grasses. Biocontrol could be used in conjunction with other weed control measures and conservation strategies to make sagebrush-steppe lands less susceptible to reinvasion.

This paper reports the effects of the most common forest fuel reduction treatments on carbon pools composed of live and dead biomass as well as potential wildfire emissions from six different sites in four western U.S. states. Research suggests most of the benefits of increased fire resistance can be achieved with relatively small reductions in current carbon stocks. Retaining or growing larger trees also reduced the vulnerability of carbon loss from wildfire. In addition, modeled vulnerabilities to carbon losses and median forest product life spans varied considerably across our study sites, which could be used to help prioritize treatment implementation.

This guidebook focuses on the use of weather and climate information in the Ecologically-Based Invasive Plant Management Framework in planning and post-management treatment evaluation. It provides land managers with resources for finding weather and climate data, and tools for incorporating this data into adaptive management planning for rangeland restoration.

This review discusses how climate change may modify invasive species and the tools used to manage them. The understanding of how and in what direction climate change will drive such changes is insufficient to adequately predict and respond. However, climate-induced changes are likely to be complex and will need to be examined on a case by case basis until more generalized frameworks can be developed. This review will help guide development of important research questions, the answers to which will better position us to devise and apply meaningful management options to address invasive species in both present and future climates.

This study compared unburned and burned sites to determine how cheatgrass and native wheatgrass abundance and distribution varied. Wheatgrass density increased in high-nutrient areas. Soil cores from burned microsites were also transplanted to a controlled area and seeded with either wheatgrass or cheatgrass to determine microsite effects on plant establishment and growth. There were differences in microsite soil properties, which were not affected by plant growth, and differences in growth but not establishment of grass seeds. Microsites are likely important for post-fire resistance of rangeland to cheatgrass establishment.
