Available in PDF, EPUB and Kindle. Book excerpt: Global forests are experiencing dramatic changes due to changes in climate as well as anthropogenic activities. Increased warming is causing the advancement of some species upslope and northward, while it is also causing widespread mortality due to increased drought conditions. In addition, increasing human population in mountain regions is resulting in elevated risk of human life and property loss due to larger and more severe wildfires. My research focuses on assessing the current vulnerability of forests and their communities in the Sierra Nevada, and how forests are projected to change in the future based on different climate change scenarios. In the first chapter I use Landsat satellite imagery to identify and attribute cause of forest disturbance between 1985 and 2011, primarily focusing on disturbances due to insect, diseases and drought. The change-detection algorithm, Landtrendr, was successfully used to identify forest disturbance, but identifying cause of disturbance was challenging due to the spectral similarities between disturbance types. Landtrendr was most successful in identifying disturbance due to insect, disease and drought in the San Bernardino National Forest, where there is little forest management activity. In the second chapter, I assess whether state or local land use policies in high-fire prone regions exist to reduce the vulnerability of residential developments to wildfire. Three specific land-use tools associated with reducing wildfire vulnerability are identified: (1) buffers around developments; (2) clustered developments; (3) restricting construction on slopes greater than 25%. The study also determines whether demographic and physical characteristics of selected California counties were related to implementing land use policies related to reducing wildfire vulnerability. Results indicate that land use policies related to preventing wildfire-related losses focus on building materials, road access, water availability and vegetation management, not the three identified land-use tools. San Diego County, the county that has experienced the most devastating fires, had the highest percentage of residential developments with both clustering and buffering. The third chapter focuses on future forest conditions. I used a Dynamic Global Vegetation Model (DGVM) to assess future vegetation dynamics and productivity under changing climate and atmospheric CO2 concentrations in the Sierra Nevada. Model results suggest that Temperate Broadleaved Evergreen Plant Functional Types (PFTs) will move upslope and eastward, replacing Temperate Needleleaved PFTs. Boreal Needleleaved Evergreen PFTs, found primarily at higher elevations, will decline dramatically as temperatures continue to increase. Gross Primary Productivity (GPP) will increase as atmospheric CO2 concentration increases, due primarily to the increase in the more productive broadleaved PFTs. Forest ecosystems play an important role in maintaining climate stability at the regional and global scales as a vital carbon sink, so understanding the role of disturbance and climate change will be vital to both scientists and policy makers in the future.

Available in PDF, EPUB and Kindle. Book excerpt: John Muir called it the "Range of Light, the most divinely beautiful of all the mountain chains I’ve ever seen." The Sierra Nevada—a single unbroken mountain range stretching north to south over four hundred miles, best understood as a single ecosystem but embracing a number of environmental communities—has been the site of human activity for millennia. From the efforts of ancient Native Americans to encourage game animals by burning brush to create meadows to the burgeoning resort and residential development of the present, the Sierra has endured, and often suffered from, the efforts of humans to exploit its bountiful resources for their own benefit. Historian David Beesley examines the history of the Sierra Nevada from earliest times, beginning with a comprehensive discussion of the geologic development of the range and its various ecological communities. Using a wide range of sources, including the records of explorers and early settlers, scientific and government documents, and newspaper reports, Beesley offers a lively and informed account of the history, environmental challenges, and political controversies that lie behind the breathtaking scenery of the Sierra. Among the highlights are discussions of the impact of the Gold Rush and later mining efforts, as well as the supporting industries that mining spawned, including logging, grazing, water-resource development, market hunting, urbanization, and transportation; the politics and emotions surrounding the establishment of Yosemite and other state and national parks; the transformation of the Hetch Hetchy into a reservoir and the desertification of the once-lush Owens Valley; the roles of the Forest Service, Park Service, and other regulatory agencies; the consequences of the fateful commitment to wildfire suppression in Sierran forests; and the ever-growing impact of tourism and recreational use. Through Beesley’s wide-ranging discussion, John Muir’s "divinely beautiful" range is revealed in all its natural and economic complexity, a place that at the beginning of the twenty-first century is in grave danger of being loved to death. Available in hardcover and paperback.

This book was released on 2012-10-22 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, there has been substantial debate over Sierra Nevada forest management. All perspectives on this debate inevitably cite “sound science” as a necessary foundation for any management practice. Over the dozen years since publication of the last science summary, the Sierra Nevada Ecosystem Project (SNEP 1996), many relevant research projects have published findings in dozens of scientific journals, yet these have not been synthesized or presented in a form that directly addresses current land management challenges. Current management usually cites a “healthy forest”1 as a primary objective. It is difficult, however, to define forest “health,” and, as a broad concept, “a healthy forest” provides few specifics to guide management or assess forest practices. Various constituencies have different ideas of forest health (i.e., sustainable timber production, fire resilience, biodiversity, etc.) making forest health unclear as an objective (Kolb et al. 1994). A premise of silviculture is that forest prescriptions can be tailored to fit a wide variety of land management objectives, once those objectives are defined. We attempt to define some of the key management objectives on National Forest System lands in the Sierra Nevada and how they might be approached through particular silvicultural prescriptions. In this paper, we focus on summarizing forest research completed at different scales and integrating those findings into suggestions for managing forest landscapes. Although many experiments and forest treatments still occur at the stand level, ecological research and recent public input have emphasized the need to address cumulative impacts and coordinate management across the forest landscape. We believe our synthesis has some novel and highly applicable management implications. This paper, however, is not intended to produce new research findings for the academic community; rather it is an effort to provide managers of Sierran forests with a summary of “the best available science.” Some of the suggestions in this paper are already used in different Forest Service management practices. There are several aspects of forest management that this paper does not address, but we would like to particularly note two omissions. The USDA Forest Service is charged with multiple-use management, which can include more objectives (e.g., socioeconomic impacts) than our focus on ecological restoration of Sierran forests. Restoration practices need both public and economic support to be socially and financially viable. Also, we do not specifically address the issues of water yield and quality in this paper, although water is one of the Sierra's most important resources. Although our focus is on forest conditions, the suggested management practices may also make forests more resilient to disturbances including climate change. Management practices that help restore the forest headwaters of Sierran watersheds will benefit water production and quality for downstream users.

Book excerpt: Across the United States, people are developing new relationships with the forest ecosystems on which they depend, with a common goal of improving the health of the land and the well-being of their communities. Practitioners and supporters of what has come to be called community forestry are challenging current approaches to forest management as they seek to end the historical disfranchisement of communities and workers from forest management and the all-too-pervasive trends of long-term disinvestment in ecosystems and human communities that have undermined the health of both. Community Forestry in the United States is an analytically rigorous and historically informed assessment of this new movement. It examines the current state of community forestry through a grounded assessment of where it stands now and where it might go in the future. The book not only clarifies the state of the movement, but also suggests a trajectory and process for its continued development.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Sierra Nevada forests represent a major ecological and economic resource for the state of California. Changes in climate and disturbance regimes, compounded with changes in forest structure from fire-exclusion, pose a critical challenge to managing Sierran forests for sustained carbon (C) sequestration and ecosystem services. My dissertation research sought to improve our understanding of how changing climate and disturbance will affect forest ecosystems in the Sierra Nevada by accounting for species-specific dynamics and interacting spatial processes that were underrepresented in landscape projections. Given the diverse tree species and forest types that differ in their optimal climate for growth and tolerance of stressors, I simulated forest dynamics in the Sierra Nevada under projected future climate and area burned as well as alternative management strategies with a species-specific, spatially explicit forest landscape model. First, I quantified how projected climate-wildfire interactions would affect forest communities and associated C dynamics. Here, results suggest that, across the Sierra Nevada, forest communities may not change as intact unit over the 21st Century and potential exists for substantial community change and C sequestration decline beyond this century. Then, I assessed the long-term successional trajectory and the ability of the system to sequester C beyond the 21st Century. Assuming climate and wildfire distributions equilibrate at late-century conditions, the results show a committed decline in forest cover and C carrying capacity, suggesting a steep reduction in the contribution of Sierra Nevada forest to the terrestrial C sink. Finally, I quantified how large-scale restoration treatments would alter the effects of changing climate and wildfire on forest C balance. I found that widespread application of fuel treatments would confer greater forest C stock stability. This work offers an improved understanding of how changing environmental conditions will affect the forest ecosystems in the Sierra Nevada and provides insights into using large-scale management strategy to manage the Sierran landscape under novel conditions.

Available in PDF, EPUB and Kindle. Book excerpt: "Wicked" problems are large-scale, long-term policy dilemmas in which multiple and compounding risks and uncertainties combine with sharply divergent public values to generate contentious political stalemates; wicked problems in the environmental arena typically emerge from entrenched conflicts over natural resource management and over the prioritization of economic and conservation goals more generally. This new book examines past experience and future directions in the management of wicked environmental problems and describes new strategies for mitigating the conflicts inherent in these seemingly intractable situations. The book: reviews the history of the concept of wicked problems examines the principles and processes that managers have applied explores the practical limitations of various approaches Most important, the book reviews current thinking on the way forward, focusing on the implementation of "learning networks," in which public managers, technical experts, and public stakeholders collaborate in decision-making processes that are analytic, iterative, and deliberative. Case studies of forest management in the Sierra Nevada, restoration of the Florida Everglades, carbon trading in the European Union, and management of the Ngorongoro Conservation Area in Tanzania are used to explain concepts and demonstrate practical applications. Wicked Environmental Problems offers new approaches for managing environmental conflicts and shows how managers could apply these approaches within common, real-world statutory decision-making frameworks. It is essential reading for anyone concerned with managing environmental problems.

Available in PDF, EPUB and Kindle. Book excerpt: Managing within social-ecological systems at the landscape scale, such as in the national forests of the Sierra Nevada of California, is challenging to natural resource managers (e.g. the U.S. Forest Service) due to the uncertainties in natural processes and the complexities in social dynamics. Collaborative adaptive management (CAM) has been recently adopted as a viable strategy to diminish uncertainties in natural processes through iterative policy experimentations and adaptations, as well as to overcome conflicting values and goals among diverse environmental stakeholders through fostering and facilitating collaborations. While many CAM studies have focused on evaluating the management impact on natural systems and processes, few have examined the social engagements and dynamics of management itself. To address this knowledge gap, I examined the various social engagements in CAM, particularly the flow of information products, dialogues in public meetings, and social connections among participants, based on my research case study--the Sierra Nevada Adaptive Management Project (SNAMP). SNAMP began in 2005 in response to the USDA National Forest Service's 2004 Sierra Nevada Forest Plan Amendment calls for managing the forest using the best information available to protect forests and homes. The participants in the project can be sorted into three primary categories of environmental stakeholders: federal and state environmental agencies, the public and environmental advocacy groups, and university scientists. The project studies the impact of forest fuel reduction treatment on forest health, fire mitigation and prevention, wildlife, and water quality and quantity at two study sites: Last Chance in the northern region of the Sierra forests at Sugar Pine in the southern region. The primary strategies and methods for fostering partnership and facilitating collaboration among the diverse participants are producing science information and making it transparent and publicly accessible, as well as facilitating discussions about such research and management results in public meetings. To evaluate the effectiveness of CAM in the case of SNAMP, I used a mixed-methods research approach (i.e. citation analysis, web analytics, content analysis, self-organizing maps, social network analysis), by leveraging available information technologies and tools, to characterize and analyze the flow of digital information products, the outcomes of facilitated discussions in SNAMP public meetings, and the resilience of the social networks in SNAMP. Some of the interesting findings include: 1) Scientific knowledge products, in the form of peer-reviewed journal publications, contributed to knowledge transfer between scientists and environmental managers; 2) facilitated discussions helped environmental stakeholders to stay engaged on the important administrative and research topics through time; 3) the social networks experienced turbulence but remained resilient due to the existence of a committed and consistent core group of environmental stakeholders that represent diverse backgrounds and interests. As the picture of how information, conversation, and social connections contributed to the success of CAM emerged, my dissertation provides recommendations to natural resource managers on how to improve in these areas for future implementations of CAM.

Available in PDF, EPUB and Kindle. Book excerpt: This long-anticipated reference and sourcebook for CaliforniaÕs remarkable ecological abundance provides an integrated assessment of each major ecosystem typeÑits distribution, structure, function, and management. A comprehensive synthesis of our knowledge about this biologically diverse state, Ecosystems of California covers the state from oceans to mountaintops using multiple lenses: past and present, flora and fauna, aquatic and terrestrial, natural and managed. Each chapter evaluates natural processes for a specific ecosystem, describes drivers of change, and discusses how that ecosystem may be altered in the future. This book also explores the drivers of CaliforniaÕs ecological patterns and the history of the stateÕs various ecosystems, outlining how the challenges of climate change and invasive species and opportunities for regulation and stewardship could potentially affect the stateÕs ecosystems. The text explicitly incorporates both human impacts and conservation and restoration efforts and shows how ecosystems support human well-being. Edited by two esteemed ecosystem ecologists and with overviews by leading experts on each ecosystem, this definitive work will be indispensable for natural resource management and conservation professionals as well as for undergraduate or graduate students of CaliforniaÕs environment and curious naturalists.
