Scientists in and beyond academia face considerable challenges to effectively sharing science, including lack of time and training, systemic disincentives, and the complexity of the modern media/attention landscape. Considering these constraints, 3 achievable shifts in mindset and practice can substantively enhance science communication efforts. Here, we provide evidence-based and experientially informed advice on how to center shared values, articulate science communication goals, and leverage the power of stories to advance our communication goals in connection with the values we share with our stakeholders. In addition to a discussion of relevant, foundational principles in science communication, we provide actionable recommendations and tools scientists can immediately use to articulate their values, identify shared values between stakeholders, set science communication goals, and use storytelling as a means of building and reinforcing relationships around shared values, thereby working productively to achieve those goals

Assessing the geomorphic sensitivity of streams and the ecological resilience of riparian ecosystems provides the basis for understanding how they have responded to disturbances and management actions and how they are expected to respond in the future.
A collaborative group of managers and scientists led by Jeanne Chambers, research ecologist and senior scientist (emeritus) with the USDA Forest Service Rocky Mountain Research Station, and geomorphologist Jerry Miller, a professor of environmental science at Western Carolina University, developed a multiscale approach to help land managers rapidly assess watersheds and categorize them based on resilience and sensitivity to disturbance. The project was built on the long-term work of Chambers and her collaborators on Great Basin riparian ecosystems.

We investigate priorities and effectiveness of wildfire suppression using a novel empirical strategy that compares 1,500 historical fire perimeters with the spatial distribution of assets at risk to identify determinants of wildfire suppression efforts. We find that fires are more likely to stop spreading as they approach homes, particularly when those homes are of higher value. This effect of threatened assets persists after controlling for physical factors (fuels, landscape, and weather) using outputs from a state-of-the-art wildfire simulation tool, and the probability that fire spread will be halted is affected by characteristics of homes 1–2 km from a fire’s edge. Our results provide evidence that wildfire suppression can substantively affect outcomes from wildfires but that some groups may benefit more from wildfire management than others.

Pre- and post-season assessments of primary (e.g. psychosocial risk factors, physical fitness and psychological capital) and secondary (e.g. work engagement, job stress and incidence of injury) outcomes facilitated comprehensive evaluation. The psychosocial education intervention program was effective at buffering participant appraisals of 12 of 13 psychosocial risk factors, namely: organizational culture, civility, psychological demands, balance, psychological support, leadership expectations, growth and development, influence, workload management, engagement, protection and safety. Participants in the psychosocial education intervention also reported lower stress relating to organizational support compared with those who not receiving the intervention program. Wildland firefighters receiving either or both intervention programs reported a significantly lower incidence rate of injury (9.9%) compared with the organisation’s 5-year average (16.0%).

We created a novel, multiple-region, N-mixture community model (MNCM) to examine the relations of riparian area and fragmentation with species richness of breeding birds in mountain ranges within the Great Basin, Nevada, USA. Projections of future riparian contraction suggested that decreases in species richness are likely to be greatest in canyons that currently have moderate (~10–25 ha) amounts of riparian vegetation. Our results suggest that if a goal of management is to maximize the species richness of breeding birds in montane riparian areas in the Great Basin, it may be more effective to focus on total habitat area than on fragmentation of patches within canyons, and that canyons with at least moderate amounts of riparian vegetation should be prioritized.

o examine the short-term effects of wildfire on belowground processes in the northern Sierra Nevada, we collected soil samples along a gradient from unburned to high fire severity over 10 months following a wildfire. This included immediate pre- and post-fire sampling for many variables at most sites. While season and soil moisture did not substantially alter pH, microbial biomass, net N mineralization, and nitrification in unburned locations, they interacted with burn severity in complex ways to constrain N cycling after fire. In areas that burned, pH increased (at least initially) after fire, and there were non-monotonic changes in microbial biomass. Net N mineralization also had variable responses to wetting in burned locations. These changes suggest burn severity and precipitation patterns can interact to alter N cycling rates following fire.

Drawing on recent syntheses of the scientific evidence, this paper examines “myths” commonly used to
oppose climate- and wildfire-adaptation of fire-prone forests. We use an established framework
designed to counter science denial by recognizing the fallacy for each myth. Fallacies are false
arguments; there are several kinds of fallacies, including cherry picking (selecting only a portion of
facts to support a conclusion), false dichotomies or oversimplification (claiming only two possible
outcomes), circular arguments, or straw man (misdirection) arguments. Learning to recognize
logical fallacies and other characteristics of science denial is an essential component of any
assessment of arguments for and against proposed actions

Recent literature reviews and syntheses provide valuable references for land management practitioners and stakeholders engaged in designing, evaluating, and implementing scientifically credible wildfire- and climate-adaptation strategies. These syntheses are supported by thousands of peer-reviewed articles that evaluated the benefits and constraints of restoring fire to fire-dependent forest landscapes. This working paper summarizes key insights from the review of studies, described in detail below, that documented unprecedented, human-caused fire exclusion and its impacts on fire-dependent forest landscapes in western North America.

Study found that expected sediment and phosphorus loads were lower under the scenario that emphasized thinning, whereas scenarios that increased prescribed burning resulted in loads that were comparable to scenarios that involved less treatment. These results reflect the finding from the WEPP analysis that prescribed burning is expected to reduce ground cover more than is thinning. Our analysis supports efforts to increase fuel reduction treatments to mitigate future wildfires, but it also suggests that preventative treatments may not avoid a long-term decline in water quality as wildfires increase with climate change.

Results suggest that dry forest species are undergoing an active range shift driven by both changing recruitment and mortality, and that increasing temperatures and drought threaten the long-term viability of many of these species in their current range. While four of the five species examined were experiencing some declines, Pinus edulis is currently most vulnerable. Management actions such as reducing tree density may be able to mitigate some of these impacts. The framework we present to estimate range-wide demographic rates can be applied to other species to determine where range contractions are most likely.
