Wildland fires Forest Service and BLM need better information and systematic approach for assessing the risks of environmental effects : report to congressional requesters. by Barry T. Hill Pdf
Decades of fire suppression, as well as changing land management practices, have caused vegetation to accumulate and become altered on federal lands. Concerns about the effects of wildland fires have increased efforts to reduce fuels on federal lands. These efforts also have environmental effects. The requesters asked GAO to (1) describe effects from fires on the environment, (2) assess the information gathered by the Forest Service and Bureau of Land Management (BLM) on such effects, and (3) assess the agencies approaches to environmental risks associated with reducing fuels. This report recommends that the Secretaries of Agriculture and the Interior (1) develop a plan to implement the agencies monitoring framework, (2) develop guidance that formalizes the assessment of landscape-level risks to ecosystems, and (3) clarify existing guidance, working with the Council on Environmental Quality (CEQ), to assess the risks of environmental effects from reducing fuels.
Making Transparent Environmental Management Decisions by Keith M. Reynolds,Paul F. Hessburg,Patrick S. Bourgeron Pdf
Since 1997, the Ecosystem Management Decision Support (EMDS) system has been used around the world to support environmental analysis and planning in many different application areas, and it has been applied over a wide range of geographic scales, from forest stands to entire countries. An extensive sampling of this diversity of applications is presented in section 2, in which EMDS application developers describe the varied uses of the system. These accounts, together with the requisite background in section 1, provide valuable practical insights into how the system can be applied in the general domain of environmental management.
Severe Wildland Fires by United States. General Accounting Office Pdf
Dangerous accumulations of brush, small trees, and other vegetation on federal lands, particularly in the western United States, have helped fuel devastating wildfires in recent years. Although a single focal point is critical for directing firefighting efforts by federal, state, and local governments, GAO found a lack of clearly defined leadership at the federal level. Authority and responsibility remain fragmented among the Department of the Interior, the Forest Service, and the states. Implementation of a performance accountability network also remains fragmented. As a result, GAO could not determine if the $796 million earmarked for hazardous fuels reduction in 2001 and 2002 has been targeted to communities and areas at highest risk. The five federal land management agencies--the National Park Service, the Fish and Wildlife Service, the Bureau of Land Management, the Bureau of Indian Affairs, and the Forest Service--have yet to begin the research needed to identify and prioritize vulnerable communities near high-risk federal lands. Moreover, the agencies are not collecting the data needed to determine if changes are needed to expedite the project-planning process. They also are not collecting data needed to measure the effectiveness of efforts to dispose of the large amount of brush and other vegetation on federal lands.
A Comparative Risk Assessment Framework for Wildland Fire Management by U.s. Department of Agriculture,Forest Service,David E. Calkin,Alan A. Ager,Matthew P. Thompson Pdf
Forests, rangelands, and other open spaces provide a broad array of ecological benefits, including critical habitat for protected species, drinking water, wood products, carbon storage, and scenic and recreational opportunities. Large, destructive wildfires threaten these values and communities adjacent to these lands. Large investments in wildland fire suppression and fuel reduction activities are being made throughout the United States in ongoing efforts to reduce human and ecological losses from wildfire (USDA and USDI 2001; Public Law 108-148 2003; Sexton 2006). Managing these investments is a challenge to multiple Federal, State, and local agencies as decision makers attempt to reduce wildfire risk over extensive areas while balancing public expectations with finite budgets (Agee 2002; Dicus and Scott 2006; Johnson and others 2006; Sexton 2006; Winter and Bigler-Cole 2006). Landscape-scale changes in vegetation structure and fuel loadings must be accomplished in order to significantly alter wildfire behavior, reduce wildfire losses, and achieve longer-term fire resiliency (for example, Agee and others 2000; Finney 2001; Peterson and others 2003; Graham and others 2004). However, the most efficient way to achieve these long-term landscape goals remains unclear, and there are different perceptions on the relative role and effectiveness of management activities versus natural and managed wildfire to reduce fuels (cf. Agee 2002; Finney and Cohen 2003; Reinhardt and others 2008). The FLAME Act of 2009 requires the U.S. Department of Agriculture Forest Service and the U.S. Department of Interior to submit to Congress a Cohesive Wildfire Management Strategy. In this report, we explore the general science available for a risk-based approach to fire and fuels management and suggest analyses that may be applied at multiple scales to inform decisionmaking and tradeoff analysis. We discuss scientific strengths and limitations of wildfire risk assessment frameworks, including the benefit of broad scalability as demonstrated by four recent case studies. We further highlight the role of comparative risk assessment, which extends the analysis to include the decision space available to managers and stakeholders to allow them to explore the tradeoffs between alternative courses of action. We identify scientific limitations of the analytical protocol and discuss questions of how to better address climate change, smoke modeling issues, and socioeconomic vulnerability, and how to better quantify treatment effectiveness. Key challenges are: achieving a balance between retaining analytical flexibility at regional and sub-regional planning scales while simultaneously retaining data and methodological consistency at the national scale, and identifying and aligning regional and national priorities to inform multi-objective strategy development. As implementation proceeds, the analytical protocol will no doubt be modified, but the contents of this report comprise a rigorous and transparent framework for comparative risk assessment built from the best available science.
A Wildfire Risk Assessment Framework for Land and Resource Management by Joe H. Scott Pdf
Wildfires can result in significant, long-lasting impacts to ecological, social, and economic systems. It is necessary, therefore, to identify and understand the risks posed by wildland fire, and to develop cost-effective mitigation strategies accordingly. This report presents a general framework with which to assess wildfire risk and explore mitigation options, and illustrates a process for implementing the framework. Two key strengths of the framework are its flexibility-- allowing for a multitude of data sources, modeling techniques, and approaches to measuring risk--and its scalability, with potential application for project, forest, regional, and national planning. The specific risk assessment process we introduce is premised on three modeling approaches to characterize wildfire likelihood and intensity, fire effects, and the relative importance of highly valued resources and assets that could be impacted by wildfire. The spatial scope of the process is landscape-scale, and the temporal scope is short-term (that is, the temporal dynamics of succession and disturbance are not simulated). We highlight key information needs, provide guidance for use of fire simulation models and risk geo-processing tools, and demonstrate recent applications of the framework across planning scales. The aim of this report is to provide fire and land managers with a helpful set of guiding principles and tools for assessing and mitigating wildfire risk.
Wildfire Risk and Hazard by U.s. Department of Agriculture,Forest Service,David E. Calkin,Alan A. Ager,Julie Gilbertson-day Pdf
Reviews have been conducted by Federal oversight agencies and blue ribbon panels to identify causal factors of the unprecedented fire suppression costs and to suggest possible modifications to Federal fire management policy and strategies (USDOI, USDA 2004; USDAOIG 2006; GAO 2007, 2009). Agency and panel member reviews have found that Federal agencies with wildland fire responsibilities are not able to quantify the value of fire management activities in terms of reducing wildfire risk to social, economic, and ecological values. In response, the Wildland Fire Leadership Council's (WFLC) monitoring strategy asked: What are the trends and changes in fire hazard on Federal lands? Fire risk assessment requires an understanding of the likelihood of wildfire by intensity level and the potential beneficial and negative effects to valued resources from fire at different intensity levels. This monitoring study was conducted to meet three broad goals: (1) address the WFLC monitoring question regarding fire hazard on Federal lands; (2) develop information useful in prioritizing where fuels treatments and mitigation measures might be proposed to address significant fire hazard and risk; and (3) respond to critiques by Office of Management and Budget, General Accounting Office, and Congress that call for risk-based performance measures to document the effectiveness of fire management programs. The results of this monitoring study are useful for project planning to quantify the potential effects of proposed actions in terms of reducing risk to specific resources of concern. Developing decision support tools that utilize an appropriate risk management framework would address many of the issues identified within government oversight reports. Specifically, the Office of Inspector General (USDAOIG 2006) reviewed USDA Forest Service (FS) large fire costs and directed that the “FS must determine what types of data it needs to track in order to evaluate its cost effectiveness in relationship to its accomplishments. At a minimum, FS needs to quantify and track the number and type of isolated residences and other privately owned structures affected by the fire, the number and type of natural/cultural resources threatened, and the communities and critical infrastructure placed at risk.” The application of fire risk and fire hazard analyses has been demonstrated at the watershed and National Forest scales (Ager and others 2007). There, specific details regarding probabilities of fire and fire intensity are linked with specific resource benefit and loss functions (Ager and others 2007). Expanding these detailed analyses to regional and national scales to provide consistent risk assessment processes is complicated by the required data specificity and difficulty in developing loss-benefit functions for the range of human and ecological values. The research effort described in this report is designed to develop, from a strategic view, a first approximation of how both fire likelihood and intensity influence risk to social, economic, and ecological values at the national scale. The approach uses a quantitative risk framework that approximates expected losses and benefits from wildfire to highly valued resources (HVR). The information gathered in this study can be summarized in tabular and map formats at many different scales using administrative boundaries or delineations of HVR such as built structure density. The overall purpose of the analysis is to provide a base line of current conditions for monitoring trends in wildfire risk over time. Future analyses would be used to determine trends and changes in response to fuel reduction investments, climate shifts, and natural disturbance events (e.g., bark beetles) between the timeframes analyzed. Monitoring data could be used to address national and regional questions regarding changes in fire risk and hazard as a result of investment strategies or changing conditions.

Responding to Oil Spills in the U.S. Arctic Marine Environment by National Research Council,Transportation Research Board,Marine Board,Division on Earth and Life Studies,Polar Research Board,Ocean Studies Board,Committee on Responding to Oil Spills in the U.S. Arctic Marine Environment Pdf
U.S. Arctic waters north of the Bering Strait and west of the Canadian border encompass a vast area that is usually ice covered for much of the year, but is increasingly experiencing longer periods and larger areas of open water due to climate change. Sparsely inhabited with a wide variety of ecosystems found nowhere else, this region is vulnerable to damage from human activities. As oil and gas, shipping, and tourism activities increase, the possibilities of an oil spill also increase. How can we best prepare to respond to such an event in this challenging environment? Responding to Oil Spills in the U.S. Arctic Marine Environment reviews the current state of the science regarding oil spill response and environmental assessment in the Arctic region north of the Bering Strait, with emphasis on the potential impacts in U.S. waters. This report describes the unique ecosystems and environment of the Arctic and makes recommendations to provide an effective response effort in these challenging conditions. According to Responding to Oil Spills in the U.S. Arctic Marine Environment, a full range of proven oil spill response technologies is needed in order to minimize the impacts on people and sensitive ecosystems. This report identifies key oil spill research priorities, critical data and monitoring needs, mitigation strategies, and important operational and logistical issues. The Arctic acts as an integrating, regulating, and mediating component of the physical, atmospheric and cryospheric systems that govern life on Earth. Not only does the Arctic serve as regulator of many of the Earth's large-scale systems and processes, but it is also an area where choices made have substantial impact on life and choices everywhere on planet Earth. This report's recommendations will assist environmentalists, industry, state and local policymakers, and anyone interested in the future of this special region to preserve and protect it from damaging oil spills.
The Photoload Sampling Technique by Robert E. Keane Pdf
Fire managers need better estimates of fuel loading so they can more accurately predict the potential fire behavior and effects of alternative fuel and ecosystem restoration treatments. This report presents a new fuel sampling method, called the photoload sampling technique, to quickly and accurately estimate loadings for six common surface fuel components (1 hr, 10 hr, 100 hr, and 1000 hr downed dead woody, shrub, and herbaceous fuels). This technique involves visually comparing fuel conditions in the field with photoload sequences to estimate fuel loadings. Photoload sequences are a series of downward-looking and close-up oblique photographs depicting a sequence of graduated fuel loadings of synthetic fuelbeds for each of the six fuel components. This report contains a set of photoload sequences that describe the range of fuel component loadings for common forest conditions in the northern Rocky Mountains of Montana, USA to estimate fuel loading in the field. A companion publication (RMRS-RP-61CD) details the methods used to create the photoload sequences and presents a comprehensive evaluation of the technique.
