Book excerpt: With the growing impacts of climate change worldwide and great uncertainty about forests' vulnerability to a changing climate in the Pacific Northwest, knowledge of coast redwood forest response is crucial. Many of the studies investigating forest response to drought focus on inland forest types rather than coastal forests. This study examined tree growth and drought response in coastal forests at restoration thinning sites, evaluating responses to local climate, tree-level competition, and site-level factors. Tree cores were extracted from previously harvested stands at three restoration sites in Redwood National Park, California, from both thinned and unthinned stands. Douglas-fir (Pseudotsuga menziesii) and coast redwood (Sequoia sempervirens) trees > 20 cm diameter at breast height were sampled (n = 274), spanning six different thinning prescriptions with varying years of thinning treatments (1978, 1995, and 2007). Generalized linear mixed effects models were used to evaluate the influence of local climate, competition, site, stand age, time since thinning, and species on tree growth and drought response. Competition was found to be negatively associated with tree growth for both tree species (p

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.

Available in PDF, EPUB and Kindle. Book excerpt: There is increased interest in multiaged management as a silvicultural and restoration tool in redwood forests of California. The effect of varying residual densities and spatial arrangements on residual stand damage, tree growth and regeneration was studied in a multicohort silviculture experiment on Jackson Demonstration State Forest. Four treatments varying in residual stand density or spatial arrangement were replicated at four sites. The experiment provided 4-year periodic growth measurements of residual trees and annual measurements of redwood and tanoak sprout height increments. Residual trees were more likely to sustain bole scarring when retained at higher densities. Crown damage was more likely to be sustained by smaller trees. From 2-6 years after partial harvesting, redwood trees grew faster than Douglas-fir or tanoak following harvest. The height increment of dominant redwood stump sprouts was much greater than dominant tanoak sprouts across all treatments and the growth of both species was directly correlated to understory light. No differences were detected for any dependent variables between dispersed and aggregated retention. No differences in sprout growth were detected when retaining a residual tree on the same root system as sprouting redwood stumps when compared against sprouts growing on a root system after all redwood stems were cut. Overall, these results suggest that managers have flexibility to manage multiaged redwood stands at different densities, and that retention of low densities of large trees will provide a good balance between overstory tree growth and understory development in multiaged stands while reducing incidences of residual stand damage.

This book was released on 2020 with total page 97 pages. Available in PDF, EPUB and Kindle. Book excerpt: Following 20th century logging, much of the natural coast redwood (Sequoia sempervirens) range consists of dense second-growth stands with slow tree growth and low biodiversity. There is a landscape-scale effort in much of coastal northern California to increase tree growth rates and ecosystem biodiversity via thinning treatments, thereby hopefully accelerating the development of old-growth forest characteristics. Redwood National Park (RNP) has been experimenting with thinning in these forest types since the 1970s. Given the interesting history of logging and restoration in RNP and the future plans for widespread thinning in this region, my thesis examined the effects of land management on forest productivity, biodiversity, and ecocultural resources. The first chapter provides a basic history of land management within the North Coast region. The second chapter investigates how redwood physiology, redwood growth, and forest biodiversity respond to restoration treatments. My Chapter 2 investigations found that thinning second-growth redwood forests 1) does not meaningfully influence tree water status, 2) increases tree gas exchange in the short-term, 3) increases tree growth in the long-term, 4) increases understory plant diversity, and 5) does not affect bird or mammal diversity. Collectively, these findings demonstrate that thinning second-growth redwood forests has the potential to accelerate the development of old-growth characteristics. This verification of the efficacy of restoration treatments is important information for land managers, as plans are currently underway to apply these treatments at the landscape-scale. Ideally, this thesis can provide useful baseline data to aid future assessments of long-term forest responses to contemporary restoration efforts.
