Untrammeling the wilderness: restoring natural conditions through the return of human-ignited fire
Year: 2024
Historical and contemporary policies and practices, including the suppression of lightning-ignited fires and the removal of intentional fires ignited by Indigenous peoples, have resulted in over a century of fire exclusion across many of the USA’s landscapes. Within many designated wilderness areas, this intentional exclusion of fire has clearly altered ecological processes and thus constitutes a fundamental and ubiquitous act of trammeling. Through a framework that recognizes four orders of trammeling, we demonstrate the substantial, long-term, and negative effects of fire…

Pathways for sustainable coexistence with wildfires
Year: 2024
Sustainable coexistence with wildfire requires overcoming vicious cycles that trap socio-ecological systems in maladaptive states. A carefully coordinated programme of innovation, education and governance, the ‘wildfire adaptation triad’, is essential for escaping maladaptation across national, community and individual scales.

A fire-use decision model to improve the United States’ wildfire management and support climate change adaptation
Year: 2024
The US faces multiple challenges in facilitating the safe, effective, and proactive use of fire as a landscape management tool. This intentional fire use exposes deeply ingrained communication challenges and distinct but overlapping strategies of prescribed fire, cultural burning, and managed wildfire. We argue for a new conceptual model that is organized around ecological conditions, capacity to act, and motivation to use fire and can integrate and expand intentional fire use as a tool. This result emerges from more considered collaboration and communication of values and needs to address…

Road fragment edges enhance wildfire incidence and intensity, while suppressing global burned area
Year: 2024
Landscape fragmentation is statistically correlated with both increases and decreases in wildfire burned area (BA). These different directions-of-impact are not mechanistically understood. Here, road density, a land fragmentation proxy, is implemented in a CMIP6 coupled land-fire model, to represent fragmentation edge effects on fire-relevant environmental variables. Fragmentation caused modelled BA changes of over ±10% in 16% of [0.5°] grid-cells. On average, more fragmentation decreased net BA globally (−1.5%), as estimated empirically. However, in recently-deforested tropical areas,…

Developing reliable and valid measures for evaluating collaborative governance and adaptability: An example from the Collaborative Forest Landscape Restoration Program
Year: 2024
In recent decades, there has been an increased emphasis on, and application of, collaborative and adaptive forms of environmental governance as a means to address complex social-ecological problems that cannot be achieved alone and support sustainable resource management. However, the majority of research in the collaborative governance and adaptability arena has relied on individual or small-n case studies. This has led to a multitude of definitions, indicators, and indices, which limits our ability to make inferences across cases and contexts. Relatedly, most research lacks formal tests of…

Climate change mitigation-adaptation relationships in forest management: perspectives from the fire-prone American West
Year: 2024
Minimizing negative impacts of climate change on human and natural systems requires mitigation of greenhouse gas emissions and adaptation to new climate conditions. Forestry provides grounds to study the relationship between these two concepts: carbon flux and storage are ecosystem services of forests, while forests are growing increasingly vulnerable to climate-driven disturbances. We examined the practice and interplay of mitigation and adaptation in the American West, which is a testbed for the conceptual balance between carbon cycling and growing climate-related risk given its abundance…

Production possibility frontiers and socioecological tradeoffs for restoration of fire adapted forests
Year: 2016
We used spatial optimization to analyze alternative restoration scenarios and quantify tradeoffs for a large, multifaceted restoration program to restore resiliency to forest landscapes in the western US. Wespecifically examined tradeoffs between provisional ecosystem services, fire protection, and the amelioration of key ecological stressors. The results revealed that attainment of multiple restoration objectives was constrained due to the joint spatial patterns of ecological conditions and socioeconomic values. We also found that current restoration projects are substantially suboptimal,…

Developing and Implementing Climate Change Adaptation Options in Forest Ecosystems: A Case Study in Southwestern Oregon, USA
Year: 2016
Climate change will likely have significant effects on forest ecosystems worldwide. In Mediterranean regions, such as that in southwestern Oregon, USA, changes will likely be driven mainly by wildfire and drought. To minimize the negative effects of climate change, resource managers require tools and information to assess climate change vulnerabilities and to develop and implement adaptation actions. We developed an approach to facilitate development and implementation of climate change adaptation options in forest management. This approach, applied in a southwestern Oregon study region,…
