Impacts of different land management histories on forest change
Year: 2017
Many western North American forest types have experienced considerable changes in ecosystem structure, composition, and function as a result of both fire exclusion and timber harvesting. These two influences co-occurred over a large portion of dry forests, making it difficult to know the strength of either one on its own or the potential for an interaction between the two. In this study, we used contemporary remeasurements of a systematic historical forest inventory to investigate forest change in the Sierra Nevada. The historical data opportunistically spanned a significant land management…

Federal fire managers’ perceptions of the importance, scarcity and substitutability of suppression resources
Year: 2017
Wildland firefighting in the United States is a complex and costly enterprise. While there are strong seasonal signatures for fire occurrence in specific regions of the United States, spatiotemporal occurrence of wildfire activity can have high inter-annual variability. Suppression resources come from a variety of jurisdictions and provide a wide range of skills, experience and associated mobility and logistical needs. Dispatch centres and regional and national resource allocation centres move suppression resources to respond to demand. However, little is known about the decision-making…

Shared visions, future challenges: a case study of three Collaborative Forest Landscape Restoration Program locations
Year: 2017
The USDA Forest Service is encouraging the restoration of select forest ecosystems through its Collaborative Forest Landscape Restoration Program (CFLRP). Collaboration is often necessary to implement landscape-scale management projects such as these, and a substantial body of research has examined the benefits and limitations of using collaboration as a tool for improving relationships, trust, and other outcomes among stakeholder groups. However, limited research has investigated the use of collaboration to achieve large-scale ecological restoration goals. Restoration poses some unique…

Efficacy of resource objective wildfires for restoration of ponderosa pine (Pinus ponderosa) forests in northern Arizona
Year: 2017
Current conditions in dry forests of the western United State have given rise to policy mandates for accelerated ecological restoration on U.S. National Forest System and other public lands. In southwestern ponderosa pine (Pinus ponderosa Laws.) forests, mechanized tree thinning and prescribed fire are common restoration treatments but are not acceptable for all sites. Currently there is much interest in managing naturally ignited fires to accomplish restoration objectives but few studies have systematically examined the efficacy of such “resource objective” wildfires for restoring historical…

A Century of Wildland Fire Research - Contributions to Long-term Approaches for Wildland Fire Management: Proceedings of a Workshop
Year: 2017
Although ecosystems, humans, and fire have coexisted for millennia, changes in geology, ecology, hydrology, and climate as well as sociocultural, regulatory, and economic factors have converged to make wildland fire management exceptionally challenging for U.S. federal, state, and local authorities. Given the mounting, unsustainable costs and difficulty translating existing wildland fire science into policy, the National Academies of Sciences, Engineering, and Medicine organized a 1-day workshop to focus on how a century of wildland fire research can contribute to improving wildland fire…

Historical perspective on the influence of wildfire policy, law, and informal institutions on management and forest resilience in a multiownership, frequent-fire, coupled human and natural system in Oregon, USA
Year: 2017
We examine the influence of wildfire institutions on management and forest resilience over time, drawing on research from a multiownership, frequent-fire, coupled human and natural system (CHANS) in the eastern Cascades of Oregon, USA. We constructed social-ecological histories of the study area’s three main landowner groups (national forest, private corporate, and tribal) using a historical framework (1905–2010). Our findings highlight two infrequently recognized linkages of multiownership, frequent-fire CHANS: (1) informal institutions (e.g., cultural norms, knowledge system and fire…

Return on investment from fuel treatments to reduce severe wildfire and erosion in a watershed investment program in Colorado
Year: 2017
A small but growing number of watershed investment programs in the western United States focus on wildfire risk reduction to municipal water supplies. This paper used return on investment (ROI) analysis to quantify how the amounts and placement of fuel treatment interventions would reduce sediment loading to the Strontia Springs Reservoir in the Upper South Platte River watershed southwest of Denver, Colorado following an extreme fire event. We simulated various extents of fuel mitigation activities under two placement strategies: (a) a strategic treatment prioritization map and (b)…

All Lands Approaches to Fire Management in the Pacific West: A Typology
Year: 2017
Since 2009, the US Department of Agriculture Forest Service has promoted an “all lands approach” to forest restoration, particularly relevant in the context of managing wildfire. To characterize its implementation, we undertook an inventory of what we refer to as fire-focused all lands management (ALM) projects, defined as projects in which fuels reduction treatments are planned or implemented across more than one landownership to reduce wildfire risk or increase forest resilience to wildfire. We focused on regions of Washington, Oregon, and California dominated by dry, fire-prone forests and…

Studying interregional wildland fire engine assignments for large fire suppression
Year: 2017
One crucial component of large fire response in the United States (US) is the sharing of wildland firefighting resources between regions: resources from regions experiencing low fire activity supplement resources in regions experiencing high fire activity. An important step towards improving the efficiency of resource sharing and related policies is to develop a better understanding of current assignment patterns. In this paper we examine the set of interregional wildland fire engine assignments for incidents in California and the Southwest Geographic Coordination Areas, utilising data from…

NFPA’s Wildland/Urban Interface: Fire Department Wildfire Preparedness and Readiness Capabilities – Final Report
Year: 2017
The increasing frequency and intensity of wildland and wildland-urban interface (WUI) fires have become a significant concern in many parts of the United States and around the world. To address and manage this WUI fire risk, local fire departments around the country have begun to acquire the appropriate equipment and offer more training in wildfire response and suppression. There is also growing recognition of the importance of wildfire mitigation and public outreach about community risk reduction. Using survey and interview data from 46 senior officers from local fire departments around the…

Available Science Assessment Project: Prescribed Fire and Climate Change in Northwest National Forests
Year: 2016
Climate change is one of the most pressing issues facing natural resource management. The disruptions it is causing require that we change how we consider conservation and resource management in order to ensure the future of habitats, species, and human communities, whether that means adopting new actions or adjusting the ways in which existing actions are implemented. However, practitioners often struggle with how to identify and prioritize specific climate adaptation actions, which are taken to either increase/enhance resilience or decrease vulnerability in a changing climate. Management…

Examining alternative fuel management strategies and the relative contribution of National Forest System land to wildfire risk to adjacent homes – A pilot assessment on the Sierra National Forest, California, USA
Year: 2016
Determining the degree of risk that wildfires pose to homes, where across the landscape the risk originates, and who can best mitigate risk are integral elements of effective co-management of wildfire risk. Developing assessments and tools to help provide this information is a high priority for federal land management agencies such as the US Forest Service (USFS) that have limited resources to invest in hazardous fuel reduction and other mitigation activities. In this manuscript we investigate the degree to which fuel management practices on USFS land can reduce wildfire exposure to human…

Evaluating Prescribed Fire Effectiveness Using Permanent Monitoring Plot Data: A Case Study
Year: 2016
Since Euro-American settlement, ponderosa pine forests throughout the western United States have shifted from high fire frequency and open canopy savanna forests to infrequent fire and dense, closed canopy forests. Managers at Zion National Park, USA, reintroduced fire to counteract these changes and decrease the potential for high-severity fires. We analyzed existing permanent monitoring plot data collected between 1995 and 2010 to assess achievement of management objectives related to prescribed fire in ponderosa pine forests. Following first entry fire, ponderosa pine (Pinus ponderosa C.…

Wilderness in the 21st Century: A Framework for Testing Assumptions about Ecological Intervention in Wilderness Using a Case Study in Fire Ecology in the Rocky Mountains
Year: 2016
Changes in the climate and in key ecological processes are prompting increased debate about ecological restoration and other interventions in wilderness. The prospect of intervention in wilderness raises legal, scientific, and values-based questions about the appropriateness of possible actions. In this article, we focus on the role of science to elucidate the potential need for intervention. We review the meaning of “untrammeled” from the 1964 Wilderness Act to aid our understanding of the legal context for potential interventions in wilderness. We explore the tension between restraint and…

Facilitating knowledge transfer between researchers and wildfire practitioners about trust: An international case study
Year: 2016
The importance of knowledge transfer between researchers, policy makers and practitioners is widely recognized. However, barriers to knowledge transfer can make it difficult for practitioners to apply the results of scientific research. This paper describes a project that addressed barriers to knowledge transfer by involving wildfire management practitioners from three countries in developing a trust planning guide. The guide provides information about trust, factors that influence trust and actions that can be taken to build trust in the context of wildfire management. The researchers…
