This book was released on 2008-08-30 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: Increasing evidence suggests that the composition and spatial configuration – the pattern – of forest landscapes affect many ecological processes, including the movement and persistence of particular species, the susceptibility and spread of disturbances such as fires or pest outbreaks, and the redistribution of matter and nutrients. Understanding these issues is key to the successful management of complex, multifunctional forest landscapes, and landscape ecology, based on a foundation of island bio-geography and meta-population dynamic theories, provides the rationale to deal with this pattern-to-process interaction at different spatial and temporal scales. This carefully edited volume represents a stimulating addition to the international literature on landscape ecology and resource management. It provides key insights into some of the applicable landscape ecological theories that underlie forest management, with a specific focus on how forest management can benefit from landscape ecology, and how landscape ecology can be advanced by tackling challenging problems in forest (landscape) management. It also presents a series of case studies from Europe, Asia, North America, Africa and Australia exploring the issues of disturbance, diversity, management, and scale, and with a specific focus on how human intervention affects forest landscapes and, in turn, how landscapes influence humans and their culture. An important reference for advanced students and researchers in landscape ecology, conservation biology, forest ecology, natural resource management and ecology across multiple scales, the book will also appeal to researchers and practitioners in reserve design, ecological restoration, forest management, landscape planning and landscape architecture.

This book was released on 2001 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A major current threat to the persistence of forest birds in Canada is forest fragmentation caused by industrial timber harvesting. The traditional silvicultural method of clearcutting creates forest fragments delineated by sharp boundaries. Conversely, selective logging techniques strive to mimic natural disturbance patterns and to produce smoother boundaries. Forest boundaries influence the ecological behaviour of forest birds in a species-specific manner. To assess the effect of forest fragmentation on bird occurrence and to derive management guidelines, I investigate the spatial association between boundaries of six bird species and forest features in a moderately harvested landscape (MHL) and an intensively harvested landscape (IHL) in New Brunswick. The focal bird species were used as indicator species for the effects of forest fragmentation. These analyses were carried out at both stand and landscape scales. I hypothesized that 1) the association of birds with forest variables would be i) species-specific and ii) stronger in the IHL than in the MHL; 2) that birds would have more common boundaries in the in the ML than in the MHL; 3) that both scales would yield complementary results, whereby the stand scale would refine coarse-scale ecological relationships of birds. By means of boundary detection algorithms and overlap statistics, I found that boundary spatial associations between vegetation and birds were more clearly defined at the stand scale in the IHL. I suggest that the spatial confinement of forest birds in clearcut forests fragments accounts for this relationships. Overall, understory forest components primarily influenced bird occurrence, yet bird response to forest features was species-specific. My findings were consistent at both analysis scales. Management efforts to preserve forest birds should strive to recreate the complexity and variability of natural ecosystems. A multi-scale approach is required in ecological research and monitoring of bird species in fragmented landscapes. For further research, I recommend that studies should include uncut controls, a broader range of treatments than the two that I analyzed, and some replication at all spatial scales. New spatial analytical tools such as boundary detection algorithms and overlap statistics are an asset to ecological studies. The methodology I used offers an objective means for evaluating land fragmentation and the effects of edgeslecotones on populations.

Book excerpt: 'At last a really useful book telling us how all the rhetoric about ecosystem approaches and sustainable forest management is being translated into practical solutions on the ground? CLAUDE MARTIN, WWF INTERNATIONAL For too long, foresters have seen forests as logs waiting to be turned into something useful. This book demonstrates that forests in fact have multiple values, and managing them as ecosystems will bring more benefits to a greater cross-section of the public? JEFFREY A. MCNEELY, CHIEF SCIENTIST, IUCN This book demonstrates that ecosystem approaches and sustainable forest management] are neither alternative methods of forest management nor are they simply complicated ways of saying the same thing. They are both emerging concepts for more integrated and holistic ways of managing forests within larger landscapes in ways that optimize benefits to all stakeholders? ACHIM STEINER AND IAN JOHNSON, FROM THE FOREWORD Recent innovations in Sustainable Forest Management and Ecosystem Approaches are resulting in forests increasingly being managed as part of the broader social-ecological systems in which they exist. Forests in Landscapes reviews changes that have occurred in forest management in recent decades. Case studies from Europe, Canada, the United States, Russia, Australia, the Congo and Central America provide a wealth of international examples of innovative practices. Cross-cutting chapters examine the political ecology and economics of forest management, and review the information needs and the use and misuse of criteria and indicators to achieve broad societal goals for forests. A concluding chapter draws out the key lessons of changes in forest management in recent decades and sets out some thoughts for the future. This book is a must-read for practitioners, researchers and policy makers concerned with forests and land use. It contains lessons for all those concerned with forests as sources of people's livelihoods and as part of rural landscapes. Published with IUCN and PROFOR

This book was released on 2016 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: Predictive species distribution models based on long-term, regional bird monitoring data can be used to assess the local distributions of forest breeding birds in the western Laurentian Great Lakes region of the United States. I modeled species distributions, species richness, and total abundance for 65 forest/forest edge nesting bird species that are abundant enough to permit statistical analysis. Predictor variables were derived from publicly available GIS land cover databases. Zero-inflated Poisson or negative binomial linear models were used to account for the excess number of zeros in the species distribution models, whereas Poisson general linear models were adequate for species richness and abundance models. Model selection was based on likelihood ratio tests for a backwards elimination process. My predictions provide predictive maps with an unprecedented fine grain, although the underlying approach parallels methods from other projects. While the predicted distributions were unique to each species, three general patterns can be recognized: 1) Twenty species showed higher abundances in the northern portion of the study area, especially Superior National Forest and adjacent parts of northern Minnesota. 2) Sixteen–eighteen species were more abundant in the southern part of the region; these species tended to avoid northeastern Minnesota but often had relatively high abundances along Lake Superior’s south shore. Some of these species were characteristic of forest edge habitats. 3) Most of the remaining 26 species showed some degree of geographic localization, but their predicted abundances exhibited no distinct north-south pattern. National forests were important for many of the species modeled. At least 10 species had distinctly high predicted abundances in one or more national forest. Northern hardwoods and mixed boreal forest were the most frequently selected positive covariates (41 and 40 out of 65 models, respectively). Pasture/hay was the most frequent negative predictor (19 models). Superior National Forest generally had the highest species richness. Overall abundances of individuals were more diffuse and generally greater in southern areas, including parts of central Minnesota and the north-central Upper Peninsula of Michigan. My analysis indicates that forest bird populations in the study area are generally patchy with locally abundant concentrations interspersed among uninhabited or sparsely inhabited areas. These results suggest that conservation efforts need to account for geographic context in addition to habitat. For example precipitation and temperature were significant predictors for 32 and 25 of 65 models respectively. Future work should include estimates of detection probability and tests of spatial predictions presented here.

Download or read book Climate Change Adaptation and Mitigation Management Options written by James M. Vose and published by CRC Press. This book was released on 2013-12-05 with total page 494 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forest land managers face the challenges of preparing their forests for the impacts of climate change. However, climate change adds a new dimension to the task of developing and testing science-based management options to deal with the effects of stressors on forest ecosystems in the southern United States. The large spatial scale and complex interactions make traditional experimental approaches difficult. Yet, the current progression of climate change science offers new insights from recent syntheses, models, and experiments, providing enough information to start planning now for a future that will likely include an increase in disturbances and rapid changes in forest conditions. Climate Change Adaptation and Mitigation Management Options: A Guide for Natural Resource Managers in Southern Forest Ecosystems provides a comprehensive analysis of forest management options to guide natural resource management in the face of future climate change. Topics include potential climate change impacts on wildfire, insects, diseases, and invasives, and how these in turn might affect the values of southern forests that include timber, fiber, and carbon; water quality and quantity; species and habitats; and recreation. The book also considers southern forest carbon sequestration, vulnerability to biological threats, and migration of native tree populations due to climate change. This book utilizes the most relevant science and brings together science experts and land managers from various disciplines and regions throughout the south to combine science, models, and on-the-ground experience to develop management options. Providing a link between current management actions and future management options that would anticipate a changing climate, the authors hope to ensure a broader range of options for managing southern forests and protecting their values in the future.
Download or read book EFFECTS OF GROUP SELECTION WITH YELLOW BIRCH BETULA ALLEGHANIENSIS RETENTION ON THE UNDERSTORY AND SAPLING LAYER IN NORTHERN HARDWOOD FORESTS written by and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract : Gap partitioning theory predicts that changes in microenvironment conditions found within a forest opening promote diversity in forest ecosystems. Under this theory we would expect to see variations in tree and understory diversity throughout and surrounding a forest opening. In order to test this theory, we examined manmade openings with legacy-tree retention in a northern hardwood forest located in the Upper Peninsula of Michigan. This work is part of an ongoing study that was started in 2003 with the creation of 49 openings centered on a reserve dominant or co-dominant yellow birch (Betula alleghaniensis Britt.). The primary objective of this research was to assess if opening size, plot location and/or plot transect azimuth had an influence on the dependent variables that we measured (herbaceous-layer species, cover groups, and sapling). Twenty reference sites were also selected from the surrounding forest and centered on a dominant or co-dominant yellow birch. At each site, the following variables were measured; herbaceous-layer species percent cover, cover groups (tree seedling ( We found that both opening size and plot location were influential on our measured variables to varying degrees. We found no evidence that transect azimuth was a significant predictor of any of the dependent variables. Opening size was significant when analyzing species diversity and evenness. Plot location was also significant when measuring species diversity as well as richness. Correlations with cover groups varied and some groups were not found to be associated with any of the opening measures (size, location, transect azimuth). Mean tallest tree sapling height was not found to be significantly different among opening sizes, but sapling height was significantly shorter in the references sites than any of the harvested openings. We also found that saplings under the legacy tree were the tallest on average when compared to the opening and the surrounding forest. Maples were by far the most abundance sapling species with sugar maple (Acer saccharum Marsh.) being the most common. Continued monitoring of sapling survival and growth will be important to gain a better understanding of tree diversity in openings with legacy- tree retention and have a better understanding of the future forest composition.
