Post-fire seeding has been widely implemented in the semiarid Great Basin because natural vegetation recovery may be compromised. Non-native species are often seeded to rapidly establish perennial cover and compete with invasive annuals. We asked whether seeding treatments with different amounts of native and non-native species followed different successional trajectories and whether they became more similar to reference communities over time. We considered restoration implications of seed mix choices and reference community options involving: (a) local unburned vegetation; and (b) reference states mapped by the USDA Natural Resources Conservation Service (NRCS) based on soil-vegetation associations.

Land management and fire management goals are increasingly framed in terms of resilience, in part due to the combined impacts of climate change, land-use change, and legacies of land management. Implicit in this framing is the recognition that resilience to wildfire involves both ecological and social dimensions. Discussions surrounding resilience often do not explicitly articulate what resources should or must be resilient to wildfire, and seldom do they make explicit for whom resilience is important. Land managers need to understand and identify which resources their communities want to be resilient to wildfire before they can outline specific actions that could be taken to support resilience for those resources. We detail an approach for bringing together land and resource managers, community institutions, and other stakeholders—those people for whom resilience is important—to achieve these objectives. We describe a series of exercises used for a workshop but present them here in a more generic form that could be adapted to a variety of landscapes, audiences, and formats.

We propose an integrated fire management approach in which all management activities before, during, and after wildfire are synergistic and improve long-term ecosystem response to fire. Harney County Wildfire Collaborative is adapting the Potential Operational Delineations (PODs) framework to improve fire outcomes and promote values at risk in the Stinkingwater Mountains pilot project area. The PODs framework serves to promote a broader geographic strategy for addressing the underlying causes of frequent and severe wildfires in the sagebrush ecosystem.

This study shows that night-time fre intensity has increased, which is linked to hotter and drier nights. Our findings are based on global satellite observations of daytime and night-time fire detections and corresponding hourly climate data, from which we determine landcover-specific thresholds of VPD (VPDt), below which fire detections are very rare (less than 95 per cent modelled chance). Globally, daily minimum VPD increased by 25 per cent from 1979 to 2020. Across burnable lands, the annual number of flammable night-time hours—when VPD exceeds VPDt—increased by 110 hours, allowing five additional nights when flammability never ceases. Across nearly one-fifth of burnable lands, flammable nights increased by at least one week across this period. Globally, night fires have become 7.2 per cent more intense from 2003 to 2020, measured via a satellite record.

Oregon partners used new spatial data to develop a geographic strategy for management of invasive annual grasses at landscape scales across jurisdictional boundaries. The geographic strategy considers annual and perennial herbaceous cover along with site resilience and resistance in categorizing areas into intact core, transitioning, and degraded areas. The geographic strategy provides 1) a conceptual framework for proactive management, building upon similar work recently begun across the Great Basin, and 2) multi-scale spatial products for both policymakers and local managers to identify strategic areas for investment of limited resources.

Minimizing vulnerability of rangeland cores to annual grass conversion includes reducing exposure to annual grass seed sources, improving resilience and resistance by promoting perennial plants, and building capacity of communities and partnerships to adapt to changing conditions and respond to the problem with appropriate actions in a timely manner.

The most stressed recommendation was that “getting the people part right” should be the priority consideration when setting up a CAM project. Actively engaging with communities from the very start is essential for developing practical solutions. Communities need to view the project as being consistent with community values and benefitting those communities. Supporting people with leadership qualities who are passionately supportive of the project is important for converting plans to action. Relationship- and capacity-building efforts that encourage productive interactions are essential for developing working relationships that enable implementation and long-term cooperation. Projects should be structured to take advantage of partners’ particular strengths and available resources; effective and timely actions are achieved most easily at smaller scales but need to be coordinated within the context of larger issues. Great value can be obtained by simply moving away from formal implementation of AM toward actions to improve the management system’s capacity to achieve success. Additional studies of smaller scale projects could provide useful information about effective approaches to capacity building.

Traditional fire practitioners are working to resist the impact of settler colonialism and reestablish cultural burning to promote traditional foods and materials, exercise their sovereignty in land management, and strengthen their communities’ cultural, physical and emotional wellbeing. Despite broad support for cultural burning, the needs of practitioners are often poorly understood by non-Native people, limiting the potential for productive cross-cultural partnerships and programs and services that serve Indigenous nations and communities. This article describes lessons learned from two Indigenous Fire Workshops that brought together cultural fire practitioners, researchers, agency and NGO representatives and members of the public to learn about the use and benefits of cultural burning in California.

Across fires and NGOs, NGO management and wellbeing, coordination and disaster experiences emerge as common barriers and enablers of relief and recovery. In many cases, local NGOs’ participation in wildfire relief and recovery included simultaneous expansion of an organisation’s mission and activities and negative impacts on staff mental health. Under the rapidly evolving circumstances of relief and the prolonged burdens of recovery, personal relationships across NGOs and government agencies significantly improved coordination of assistance to communities. Finally, interviewees expressed greater confidence when responding to wildfires if they had previous experience with a disaster, although the COVID-19 pandemic presented distinct challenges on top of pre-existing long-term recovery work.

We conducted 53 interviews across four case studies in the western United States where federal land management agencies and cooperative actors are working together to accelerate the implementation of prescribed fire to understand the range of actors and associated roles they play. We found that interviewees identified 67 different organizations spanning local to national scales that played a variety of roles to support prescribed fire implementation, mainly communications, prescribed burn labor, fundraising, burning expertise, and burning on neighboring lands. Many actors did not serve in intentional bridging roles, but they filled key roles in the governance networks necessary to implement prescribed fire.
