This book was released on 2010-08-13 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: California's Bay-Delta estuary is a biologically diverse estuarine ecosystem that plays a central role in the distribution of California's water from the state's wetter northern regions to its southern, arid, and populous cities and agricultural areas. Recently, the Fish and Wildlife Service and the National Marine Fisheries Service required changes (reasonable and prudent alternatives, or RPAs) in water operations and related actions to avoid jeopardizing the continued existence and potential for recovery of threatened species of fish. Those changes have reduced the amount of water available for other uses, and the tensions that resulted have been exacerbated by recent dry years. The complexity of the problem of the decline of the listed species and the difficulty of identifying viable solutions have led to disagreements, including concerns that some of the actions in the RPAs might be ineffective and might cause harm and economic disruptions to water users, and that some of the actions specified in the RPAs to help one or more of the listed species might harm others. In addition, some have suggested that the agencies might be able to meet their legal obligation to protect species with less economic disruptions to other water users. The National Research Council examines the issue in the present volume to conclude that most of the actions proposed by two federal agencies to protect endangered and threatened fish species through water diversions in the California Bay-Delta are "scientifically justified." But less well-supported by scientific analyses is the basis for the specific environmental triggers that would indicate when to reduce the water diversions required by the actions.

Available in PDF, EPUB and Kindle. Book excerpt: Thoroughly researched and finely crafted, After the Grizzly traces the history of endangered species and habitat in California, from the time of the Gold Rush to the present. Peter S. Alagona shows how scientists and conservationists came to view the fates of endangered species as inextricable from ecological conditions and human activities in the places where those species lived. Focusing on the stories of four high-profile endangered species—the California condor, desert tortoise, Delta smelt, and San Joaquin kit fox—Alagona offers an absorbing account of how Americans developed a political system capable of producing and sustaining debates in which imperiled species serve as proxies for broader conflicts about the politics of place. The challenge for conservationists in the twenty-first century, this book claims, will be to redefine habitat conservation beyond protected wildlands to build more diverse and sustainable landscapes.

This book was released on 2012-10-01 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: Extensively modified over the last century and a half, California's San Francisco Bay Delta Estuary remains biologically diverse and functions as a central element in California's water supply system. Uncertainties about the future, actions taken under the federal Endangered Species Act (ESA) and companion California statues, and lawsuits have led to conflict concerning the timing and amount of water that can be diverted from the Delta for agriculture, municipal, and industrial purposes and concerning how much water is needed to protect the Delta ecosystem and its component species. Sustainable Water and Environmental Management in the California Bay-Delta focuses on scientific questions, assumptions, and conclusions underlying water-management alternatives and reviews the initial public draft of the Bay Delta Conservation Plan in terms of adequacy of its use of science and adaptive management. In addition, this report identifies the factors that may be contributing to the decline of federally listed species, recommend future water-supple and delivery options that reflect proper consideration of climate change and compatibility with objectives of maintaining a sustainable Bay-Delta ecosystem, advises what degree of restoration of the Delta system is likely to be attainable, and provides metrics that can be used by resource managers to measure progress toward restoration goals.

Available in PDF, EPUB and Kindle. Book excerpt: The combined impacts of climate change and land use are projected to drive unprecedented rates of environmental change and biodiversity loss this century. Given the rapidly growing human populations in mediterranean-climate systems, land use may pose a more immediate threat to biodiversity than climate change, however, the relative future impact of each driver remains largely unaddressed. Focusing on California sage scrub (CSS), a plant association of considerable diversity, endemism, and threatened status in the mediterranean-climate California Floristic Province, I investigate the future threats of projected land use and climate change on CSS distribution and diversity. California sage scrub is highly reduced and fragmented in distribution and contains a large number of threatened and endangered species that may be particularly vulnerable to further habitat loss from future land use and climate change. My objectives are to (1) assess the role of climate in shaping current patterns of CSS species and floristic group distributions at a regional scale, (2) predict changes in the distribution of CSS species and growth forms, testing whether niche, geographic, or bioclimatic factors explain the magnitude of species response to projected climate change and identifying potential future impacts on CSS community structure and diversity, and (3) compare the relative threats of projected land use and climate change on CSS in California to better understand how threats may vary spatially and temporally. Using a species distribution modeling approach, I modeled the contemporary climate relationship and future (mid- and late-century) geographic distributions of 33 dominant CSS shrub species assuming two possible climate change trajectories (warmer wetter and warmer drier) and two dispersal scenarios (unlimited dispersal and no dispersal). Habitats loss from future land use was calculated from projected land use overlays (objective 3). Current models reveal climate is a strong predictor of individual CSS species and floristic group distributions at regional scales. Modeling at a floristic group level provides important information about the differences in current climatic niches within CSS, highlighting the potential for community-level modeling approaches to investigate plant distribution patterns. Under projected climate change, I predict two overall patterns in CSS habitat change consistent across climate change trajectories: southern habitat contraction and northern habitat expansion. By late-century (2080s) species habitat losses will range from moderate (unlimited dispersal) to severe (no dispersal), with succulent species showing minimal habitat loss and overall net habitat gains (unlimited dispersal). Individual shifts in the distribution of CSS species translate to considerable community restructuring and diversity shifts at northern and southern extents of CSS, with implications for future CSS management and conservation. I find the degree of threat posed by climate change relative to land use depends upon dispersal scenario, with land use and climate change posing similar future threats under no dispersal scenarios and land use posing a greater future threat under unlimited dispersal scenarios. Impacts will also vary spatially between Central Coast and South Coast California Ecoregions, with high CSS habitat and diversity losses from both land use and climate change predicted in the South Coast even under best-case unlimited dispersal scenarios, but considerable habitat gains and increased diversity predicted in the Central Coast. Furthermore, I find that regions of the South Coast that are currently intact but projected to undergo future anthropogenic conversion will have disproportionately high losses in CSS species richness driven by climate change. These findings highlight the potential for land use and climate change to have compounding negative impacts on CSS and emphasize the necessity to include analyses of both drivers in conservation and resource management planning.

Available in PDF, EPUB and Kindle. Book excerpt: Fire in California’s Ecosystems describes fire in detail—both as an integral natural process in the California landscape and as a growing threat to urban and suburban developments in the state. Written by many of the foremost authorities on the subject, this comprehensive volume is an ideal authoritative reference tool and the foremost synthesis of knowledge on the science, ecology, and management of fire in California. Part One introduces the basics of fire ecology, including overviews of historical fires, vegetation, climate, weather, fire as a physical and ecological process, and fire regimes, and reviews the interactions between fire and the physical, plant, and animal components of the environment. Part Two explores the history and ecology of fire in each of California's nine bioregions. Part Three examines fire management in California during Native American and post-Euro-American settlement and also current issues related to fire policy such as fuel management, watershed management, air quality, invasive plant species, at-risk species, climate change, social dynamics, and the future of fire management. This edition includes critical scientific and management updates and four new chapters on fire weather, fire regimes, climate change, and social dynamics.

Available in PDF, EPUB and Kindle. Book excerpt: In Not So Golden State, leading environmental historian Char Miller looks below the surface of California's ecological history to expose some of its less glittering conundrums. In this necessary work, Miller asks tough questions as we stand at the edge of a human-induced natural disaster in the region and beyond. He details policy steps and missteps in public land management and examines the impact of recreation on national forests, parks, and refuges, assessing efforts to restore wild land habitat, riparian ecosystems, and endangered species. Why, during a devastating five-year drought, is the Central Valley’s agribusiness still irrigating its fields as if it were business as usual? What’s unusual, Miller reveals, is that northern counties rich in groundwater sell it off to make millions while draining their aquifers toward eventual mud. Why, when contemporary debate over oil and gas drilling questions reasonable practices, are extractive industries targeting Chaco Canyon National Historic Park and its ancient sites, which are of inestimable value to Native Americans? How do we begin to understand “local,” a concept of hope for modern environmentalism? After all, Miller says, what we define as local determines how we might act in its defense. To inhabit a place requires placed-based analyses, whatever the geographic scope—examinations rooted in a precise, physical reality. To make a conscientious life in a suburb, floodplain, fire zone, or coastline requires a heightened awareness of these landscapes’ past so that we can develop an intensified responsibility for their present condition and future prospects. Building a more robust sense of justice is the key to creating resilient, habitable, and equitable communities. Miller turns to Aldo Leopold’s insight that “all history consists of successive excursions from a single starting point,” a location humans return to "again and again to organize another search for a durable scale of values.” This quest, a reflection of our ambition to know ourselves in relation to time and space, to organize our energy and structure our insights, is as inevitable as it is unending. Turning his focus to the tensions along the California coastline, Miller ponders the activities of whale watching and gazing at sea otters, thinking about the implications of the human desire to protect endangered flora and fauna, which makes the shoreline a fraught landscape and a source of endless stories about the past and present. In the Los Angeles region these connections are more obvious, given its geography. The San Gabriel Mountains rise sharply above the valleys below, offering some of the steepest relief on the planet. Three major river systems—the Santa Ana, San Gabriel, and Los Angeles—cut through the range’s sheer canyons, carrying an astonishing amount of debris that once crashed into low-lying areas with churning force. Today the rivers are constrained by flood-control dams and channels. Major wildfires, sparked by annual drought, high heat, and fierce Santa Ana winds, move at lightning speed and force thousands to flee. The city’s legendary smog, whose origins lie in car culture, was fueled in part by oil brought to the region's surface in the late nineteenth century. It left Angelenos gasping for breath as climatic conditions turned exhaust into a toxic ozone layer trapped by the mountains that back in the day were hard to see. Clearing the befouled skies took decades. Every bit as complex is the enduring effort to regenerate riparian health and restore wildlife habitat in a concrete-hardened landscape. The emerging tensions are similar to those threading through the U.S. Forest Service’s management of the Angeles National Forest, exacerbated whenever a black bear ambles into a nearby subdivision. How we build ourselves into these spaces depends on the removal of competing users or uses: a historic strawberry patch gives way to a housing development, a memorial forest goes up in smoke, a small creek tells a larger tale of the human impress, and struggles over water—a perennial issue in this dry land—remind us we're not as free of the past as we'd like to think. Neither are we removed from the downwind consequences of our choice to live in fire’s path. The West does not burn every summer; it just seems that way. And not every fire is a smoke signal of distress. Picking through the region’s fiery terrain is as tricky as trying to extinguish a roaring blaze in the August heat. There are lessons to be had by examining how we respond to the annual conflagrations. The Wallow Fire, which in 2011 burned hundreds of thousands of acres in remote Arizona, sparked equal amounts of political grandstanding and hand-wringing about wildfire-fighting strategies. Beyond the headlines and flashy, smoke-filled images lay another reality. The creation of defensible space and the thinning of forests communities—signs of homeowners' and state and federal agencies' proactive intervention—meant few structures burned during the monthlong firestorm. That such good news is rarely reported is part and parcel of another ethical dilemma too rarely acknowledged: the decision to live in fire zones should come coupled with homeowners’ responsibility to do all they can to ensure their homes don't go up in smoke. How they build their homes and landscape its environs are essential steps in defending their space. That obligation comes with another, made clear in the 2013 Yarnell Hill, which took the lives of nineteen firefighters. To make our houses fire-safe is to give firefighters a fighting chance. This reciprocity and the social compact it depends on require us to believe we inhabit common ground with our neighbors, a realization that should build a stronger sense of community. But it's a tough concept to promote in a bewilderingly antisocial political environment, when budgets for fire prevention are slashed as part of larger efforts to defund the nation-state. Or when the very reasons some seek to live in isolated, mountainous environs clash with the larger need to act in concert with their communities. Fires illuminate many things, not least the ties that bind and those that are frayed. Miller develops his argument from a variety of places and perspectives. Most of the pieces ask a series of questions about a particular landscape—Gila National Forest, Death Valley, Zion, Arches, and Rocky Mountain National Parks, and a host of other iconic western scenic spots. Why do we conceive of wilderness as a preserve, separate and inviolate? Who benefits—or does not—from the idea that such landscapes are, or ought to be, untrammeled? Why has this intellectual construction, and the preservationist ethos it depends on, come to dominate contemporary environmentalism? Related queries bubble up after Miller spends time in the newest national park, Pinnacles in central California, or one of the most venerable, the Grand Canyon in northern Arizona. What impact has the long history of tourism and recreation had on these public lands? Maintaining trails that weave through the Yosemite Valley is an arduous, incessant task made more difficult by the visitors pouring in to John Muir’s favorite terrain or rushing to rock climb in Minerva Hoyt’s beloved Joshua Tree. Still more daunting is the prospect of sustained ecological restoration and habitat regeneration under current conditions and those that climate change is generating across the West. Once again Aldo Leopold can be a guide. “A member of a biotic team is shown by an ecological interpretation of history,” he once observed, adding that many “historical events, hitherto explained solely in terms of human enterprise, were actually biotic interactions between people and land.” Only when “the concept of land as a community really penetrates our intellectual life” will history, as a subject and methodology, become fully realized. Not So Golden State contributes powerfully toward the realization of this enduring cross-generational endeavor.
