Book excerpt: The natural recovery of coast redwood forests following a logging event is not fully understood. Recent studies, in the redwood central range, have found that un-restored and unmanaged second-growth forest stands can begin to recover and exhibit characteristics of old-growth stands within 100 years or less. The goal of this study was to determine if redwood stands in their southern range are recovering naturally. A total of 160 sample plots were selected randomly within old-growth and second-growth study sites. The data collected included stand density, tree size structure, canopy cover, species diversity, and species composition. Special habitat features were analyzed and included measurements of snags, large woody debris (LWD), fire hollows, and observations of reiterated trunks in second-growth stands. Mean comparisons and trends among the second-growth stands and old-growth stands were analyzed to determine the stage of development of second-growth stands. The second-growth stands were also examined to see if they exhibited old-growth characteristics. Results demonstrated that several stand characteristics were recovering naturally and that second-growth forests appear to be progressing through the stand development stage of understory reinitiation. These findings suggest that unmanaged second-growth redwood stands have the potential for natural recovery in their southern range.

Book excerpt: Evidence is mounting that redwood forests, like many other ecosystems, cannot survive as small, isolated fragments in human-altered landscapes. Such fragments lose their diversity over time and, in the case of redwoods, may even lose the ability to grow new, giant trees. The Redwood Forest, written in support of Save-the-Redwood League's master plan, provides scientific guidance for saving the redwood forest by bringing together in a single volume the latest insights from conservation biology along with new information from data-gathering techniques such as GIS and remote sensing. It presents the most current findings on the geologic and cultural history, natural history, ecology, management, and conservation of the flora and fauna of the redwood ecosystem. Leading experts -- including Todd Dawson, Bill Libby, John Sawyer, Steve Sillett, Dale Thornburgh, Hartwell Welch, and many others -- offer a comprehensive account of the redwoods ecosystem, with specific chapters examining: the history of the redwood lineage, from the Triassic Period to the present, along with the recent history of redwoods conservation life history, architecture, genetics, environmental relations, and disturbance regimes of redwoods terrestrial flora and fauna, communities, and ecosystems aquatic ecosystems landscape-scale conservation planning management alternatives relating to forestry, restoration, and recreation. The Redwood Forest offers a case study for ecosystem-level conservation and gives conservation organizations the information, technical tools, and broad perspective they need to evaluate redwood sites and landscapes for conservation. It contains the latest information from ground-breaking research on such topics as redwood canopy communities, the role of fog in sustaining redwood forests, and the function of redwood burls. It also presents sobering lessons from current research on the effects of forestry activities on the sensitive faunas of redwood forests and streams. The key to perpetuating the redwood forest is understanding how it functions; this book represents an important step in establishing such an understanding. It presents a significant body of knowledge in a single volume, and will be a vital resource for conservation scientists, land use planners, policymakers, and anyone involved with conservation of redwoods and other forests.

This book was released on 2016 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mature second-growth coast redwood (Sequoia sempervirens) forests are an important and uncommon resource in the redwood region. Development of second-growth redwood forests beyond rotation age (~50 years) is not well understood. Continuous long-term data are especially lacking, considering that the maximum possible age of second-growth stands is now over 150 years. Two permanent observation plots in Arcata, CA, established in 1923 by Woodbridge Metcalf and last measured in 1990, provide a unique opportunity to examine the development of coast redwood forest regenerating after logging in ~1880. We surveyed the Metcalf plots using modern methods and assembled a complete dataset from 1923 to 2015. We also built new allometric models for second-growth coast redwood to predict tree-level quantities such as total biomass and leaf area from ground-based measurements. The Metcalf plots nearly doubled in total basal area over the study period, reaching 124 and 143 m2 ha-1, and redwood increased in proportional dominance as the non-redwood species steadily declined in number. These results, along with substantial density-independent mortality, suggest a transition to a maturation stage of forest development at ~83 years since logging. In the most recent surveys (~135 years since logging), the leaf area index values of trees alone for the Metcalf plots (9.8 and 12.7) are similar to nearby old-growth forests (11.6-15.9). Our results from relatively unmanaged conditions can be compared to silvicultural treatments of regenerating coast redwood forest meant to accelerate development of old-growth characteristics, especially as treated stands move beyond rotation age.

Available in PDF, EPUB and Kindle. Book excerpt: The Coast Redwood Forests in a Changing California Science Symposium was held June 21-23, 2011, at UC Santa Cruz with just under 300 registrants in attendance. Participants ranged in background from graduate-level students to university forestry faculty, land managers, conservation groups, public agencies, and land trust members. The symposium was strategically held in Santa Cruz, near the southern end of the redwood region. Designed to present the state of our knowledge about Californias coast redwood forest ecosystems and sustainable management practices, this symposium was built on earlier redwood science symposia held in Arcata, CA, in June, 1996 and in Santa Rosa, CA, in March, 2004. The first day of the symposium consisted of two simultaneous field tours, one to the North County and one to the South County. The North County tour focused on active redwood timber management on corporate ownerships operating under the unique policies that dictate decisionmaking on the central coast, and Cal- Polys forest management and research at its Swanton Pacific Ranch. It also included a brief tour of the Big Creek Lumber Company sawmill and a visit to areas burned in the more than 7,000-acre Lockheed Fire of 2009. The South County tour traversed the range of redwood forest conditions from the old growth of Henry Cowell State Park and the uncut 120 year old young growth of Nisene Marks State Park to uneven-aged young-growth stands established by individual tree selection harvesting on nonindustrial forest lands. Opening remarks started the second day of the symposium and began the academic concurrent sessions. Local historian Sandy Lydon spoke about the special history of the redwoods in the region, recounting stories from his boyhood about roaming through the forests and giving a brief synopsis of the settlement of the area. Steve Sillett, Humboldt State University forestry professor, described his experiences climbing the redwoods and his discoveries in the redwood forest canopy ecosystems, as well as his findings on tree growth from dendrochronology measurements. Ruskin Hartley, Executive Director and iv Secretary of Save the Redwoods League, called on the audience to set S2audacious goals and collaborative actions.S3 He maintained that nature does not develop boundaries and that in moving forward, we should focus on a shared set of goals and that public and private land should progress simultaneously. Concluding the session, Ron Jarvis, Home Depots VP of sustainability talked candidly about the role of environmental sustainability practices and policies as part of the home improvement retailers business model. He noted that when he began in the sustainability department, he undertook a 2-year long project to understand where every sliver of wood from over 9,000 products originated to ensure sustainable wood practices. Over 75 concurrent oral presentations were showcased over 2 days, pertaining to the topics of: Ecology (15 presentations); Silviculture and Restoration (11 presentations); Watershed and Physical Processes (22 presentations); Wildlife, Fisheries, Aquatic Ecology (10 presentations); Forest Health (10 presentations); Economics and Policy (6 presentations); Monitoring (7 presentations). In addition, almost 40 posters were displayed during the evening reception, ranging in topic from postfire response, to long-term watershed research, and community forestry models. Held outside on the warm Santa Cruz evening, participants enjoyed a strolling dinner and networking with colleagues, making the reception a highlight of the symposium. The symposium concluded with closing remarks about the future of research in the redwood region from John Helms, UC Berkeley and Mike Liquori, Sound Watershed. In addition, a panel including Dan Porter, the Nature Conservancy, Lowell Diller, Green Diamond, and Kevin OHara, UC Berkeley discussed the interface of research, management, and conservation. The overall discussion led to the conclusion that academic research and applied research should be made available to the field as a whole as findings progress and that more opportunities for networking and interactions should be made available to the forestry community. Overall, the symposium fulfilled its purpose to identify key knowledge gaps, bring together multidisciplinary teams, and help identify future opportunities for collaboration. Participants were pleased with the presenters and research shown. Many noted that a highlight of the symposium was being able to meet and interact with others whose works they had previously cited in their own research. Of the approximately one half of participants who completed the followup survey, 100% hoped to see more events like the 2011 Redwood Symposium.

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.

Book excerpt: "This completely new edition of Terrestrial Vegetation of California clearly documents the extraordinary complexity and richness of the plant communities and of the state and the forces that shape them. This volume is a storehouse of information of value to anyone concerned with meeting the challenge of understanding, managing or conserving these unique plant communities under the growing threats of climate change, biological invasions and development."—Harold Mooney, Professor of Environmental Biology, Stanford University "The plants of California are under threat like never before. Traditional pressures of development and invasive species have been joined by a newly-recognized threat: human-caused climate change. It is essential that we thoroughly understand current plant community dynamics in order to have a hope of conserving them. This book represents an important, well-timed advance in knowledge of the vegetation of this diverse state and is an essential resource for professionals, students, and the general public alike."—Brent Mishler, Director of the University & Jepson Herbaria and Professor of Integrative Biology, University of California, Berkeley
