As our climate crisis deepens, feelings of anxiety, grief, and hopelessness are on the rise. Staying engaged in climate solutions over the long term requires us to avoid emotional burnout; yet when bombarded with so much bad news – mass extinction, dying oceans, displaced communities and burning forests – this is easier said than done. This talk explores the mental health dimensions of climate disruption among students, scientists, activists, and frontline communities, and shares practical strategies for building the emotional resilience to channel despair into meaningful action.

Wildfire regimes are changing dramatically across North American deserts with the spread of invasive grasses. Invasive grass fire cycles in historically fire-resistant deserts are resulting in larger and more frequent wildfire. This study experimentally compared how single and repeat fires influence invasive grass-dominated plant fuels in the Great Basin, a semi-arid, cold desert, and the Mojave, a hyper-arid desert. Both study sites had identical study designs. In the summer of 2011, we experimentally burned half of each experimental block, the other half remaining as an unburned control. Half of the burned plots were reburned 5 years later to simulate increasing burn frequency. We estimated non-woody plant biomass, cover, and density in plots from 2017 to 2020.

This research brief reports that applying salvaged biocrust material to severely disturbed soil rapidly reestablished favorable biocrust characteristics and stabilized soil more than doing nothing. This is likely a useful restoration strategy when unavoidable soil disturbances are planned and there are opportunities to salvage material.

This short synthesis highlights findings of the national Fire and Fire Surrogates Study, which conducted an integrated network of experiments at 13 sites across the United States, many of which took place on National Forest lands. Results suggest that more species increased in number than decreased. For example, researchers reported that populations of western bluebirds (Sialia mexicana) increased following prescribed fire; whereas mountain chickadees (Poecile gambeli) decreased in response to thinning treatments. The positive and negative responses of deer mice (Peromyscus maniculatus), gray-collared chipmunks (Tamias cinereicollis) and least chipmunks (T. minimus) varied among the sites; but the overall biomass of small mammals increased in response to the fire treatments. Researchers also found that small mammals’ responses were related to fire uniformity: the more heterogeneous the post-fire landscape, the greater the proportion of positive responses.

This study brought together ecologists and social scientists to confront this challenge and consider how to better promote both social and ecological resilience to a more flammable world. The result led to the new insights highlighted in the paper “Rethinking resilience to wildfire” – that catastrophic wildfires are forcing us to rethink what social–ecological resilience to wildfire means, and accept that more diverse approaches to resilience thinking are needed to facilitate human coexistence with wildfire.

In this webinar, a panel of scientists and practitioners will discuss a number of management techniques and research questions being utilized or tested in an effort to reduce the presence of introduced grasses and restore the historic fire regime. These include:
- Researching whether fire historically maintained the clumpy pattern of native vegetation in a self-perpetuating cycle.
- Reducing the risk of wildfire severity and extent, retaining native plant communities, and maintaining ecological processes in dry desert systems through a variety of invasive species removal techniques.
- Producing fire breaks, or strips of treatment intended to repress the forward progress of wildfires, through restoration of native vegetation patchiness and pruning of native woody species.
- Utilizing new technologies to detect invasive grasses and monitor their spread, assess treatment and cost-effectiveness, and present results from a networked experiment that tests vegetation management practices across the southwestern US.

These products establish the first comprehensive national baseline for measuring vegetation change in the USA, providing land managers and policymakers with a tool to support vegetation restoration and fuel management activities at regional to national scales. Users have applied these products to support a variety of land management needs including exploring ecosystem dynamics, assessing current and desired conditions, and simulating the effects of management actions. In an era of rapid ecological change, these products provide land managers with an adaptable tool for understanding ecosystems and predicting possible future conditions.

The daily probability of a male sage-grouse moving among leks ranged 0.003 in 2011 to 0.010 in 2013, indicating high daily lek fidelity throughout the season, although there was a 5–42% chance annually a male would move at least once to another lek throughout the season. Interlek movement probabilities were strongly affected by day of year, peaking early in the lek season. Interlek movements were positively associated with elevation. Seasonal interlek movements occurred more frequently than previously reported, and can bias lek counts in early spring as males move from low to high elevation leks, which reinforces interlek movements as a critical component of lek ecology.

This paper argues that the expansion of prescribed fire will require new public policies that both protect burn practitioners from liability and compensate for losses from potential fire escapes.
