Download or read book Northwest Forest Plan the First 10 Years 1994 2003 Rural communities and economies written by and published by . This book was released on 2006 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: The socioeconomic monitoring report addresses two evaluation questions posed in the Northwest Forest Plan (the Plan) Record of Decision and assesses progress in meeting five Plan socioeconomic goals. Volume I of the report contains key findings. Volume II addresses the question, Are predictable levels of timber and nontimber resources available and being produced? It also evaluates progress in meeting the goal of producing a predictable level of timber sales, special forest products, livestock grazing, minerals, and recreation opportunities. The focus of volume III is the evaluation question, Are local communities and economies experiencing positive or negative changes that may be associated with federal forest management? Two Plan goals are also assessed in volume III: (1) to maintain the stability of local and regional economies on a predictable, long-term basis and, (2) to assist with long-term economic development and diversification to minimize adverse impacts associated with the loss of timber jobs. Progress in meeting another Plan goal--to promote agency-citizen collaboration in forest management--is evaluated in volume IV. Volume V reports on trends in public values regarding forest management in the Pacific Northwest over the past decade, community views of how well the forest values and environmental qualities associated with late-successional, old-growth, and aquatic ecosystems have been protected under the Plan (a fifth Plan goal), and issues and concerns relating to forest management under the Plan expressed by community members. Volume VI provides a history of the Northwest Forest Plan socioeconomic monitoring program and a discussion of potential directions for the program.

Available in PDF, EPUB and Kindle. Book excerpt: Succession-nothing in plant, community, or ecosystem ecology has been so elaborated by terminology, so much reviewed, and yet so much the center of controversy. In a general sense, every ecologist uses the concept in teaching and research, but no two ecologists seem to have a unified concept of the details of succession. The word was used by Thoreau to describe, from a naturalist's point of view, the general changes observed during the transition of an old field to a forest. As data accumulated, a lengthy taxonomy of succession developed around early twentieth century ecologists such as Cooper, Clements, and Gleason. Now, nearer the end of the century, and after much discussion concerning the nature of vegetation communities, where do ecologists stand with respect to knowledge of ecological succession? The intent of this book is not to rehash classic philosophies of succession that have emerged through the past several decades of study, but to provide a forum for ecologists to present their current research and present-day interpretation of data. To this end, we brought together a group of scientists currently studying terrestrial plant succession, who represent research experience in a broad spectrum of different ecosystem types. The results of that meeting led to this book, which presents to the reader a unique summary of contemporary research on forest succession.

This book was released on 2006 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: A recurrent theme in the development of U.S. forest policies has been the assertion of strong positive relations among communities, economies, and natural resource management. Now as a new round of federal land management planning is getting underway, questions are being raised about the strength of that assertion and how to view communities following a decade of reduced federal harvests. This report examines these questions considering the 433 communities in six Bureau of Land Management districts in western Oregon. It discusses the ways that forest-based communities have been considered in the context of federal forest management planning, and it summarizes information on socioeconomic conditions and trends for communities in western Oregon.

Available in PDF, EPUB and Kindle. Book excerpt: Tropical forests are an undervalued asset in meeting the greatest global challenges of our time—averting climate change and promoting development. Despite their importance, tropical forests and their ecosystems are being destroyed at a high and even increasing rate in most forest-rich countries. The good news is that the science, economics, and politics are aligned to support a major international effort over the next five years to reverse tropical deforestation. Why Forests? Why Now? synthesizes the latest evidence on the importance of tropical forests in a way that is accessible to anyone interested in climate change and development and to readers already familiar with the problem of deforestation. It makes the case to decisionmakers in rich countries that rewarding developing countries for protecting their forests is urgent, affordable, and achievable.

Book excerpt: Communities and Forests offers a timely view of the changing face of forests and forestry in North America today. In examining interactions between people and forests, the book shows that forests are as much a social institution as they are a biological resource. The book begins with an investigation of the historical and sociological foundations of community-based forest management. Chapters in the second section highlight the diverse issues surrounding community forestry, specifically the conflicts between the management of public forestlands and the interests of various stakeholders in using forests as a public good. The final section examines urban forestry, focusing on both the importance of forestry in urban settings and the demographic shifts that have brought people with urban values and lifestyles to rural, forested settings.

This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "Climate models overwhelmingly show that 98% of the Earth experienced its highest level of warming during the twentieth century. During this period, a plethora of studies have demonstrated significant impacts on biota. The focus of my thesis is to study the stability of ecological communities to changes in climate, both observed and predicted. Climate change is often used synonymously with destabilization in the context of ecological systems. One of my objectives is to study whether specific types of ecological organization amplify or dampen potential destabilization due to specific types of climate change. I consider two types of highly non-equilibrium communities: a tropical planted forest and a seasonal Arctic tundra food web. Biodiversity may provide mechanisms through which to buffer community functioning to changing environmental conditions. In my first chapter, I use data from a ca. 15 year-old tropical planted forest experiment to study the stability of tree communities across a gradient of species richness to extreme climate events during this period. Using a bootstrapping procedure, I develop a statistical method for the detection of stress response in community growth and mortality as a measure of stability. In one-species communities, in contrast to higher richnesses, growth is strongly regulated by climate extremes and mortality is higher during a long period of drought. Using indicators of loss of resilience or critical slowing down, I show that for the drought extremes experienced at the experiment there may be an effect of diversity on loss of resilience, with one-species communities being more prone to massive die-off. In my second and third chapters, I consider a simplified Arctic tundra food web in a strongly seasonal community on Bylot Island (lemming-fox-goose-owl) where biodiversity varies temporally due to migrating species. To ultimately study stability to changing climatic conditions in the Arctic, a model which captures the seasonality of the community is necessary. Without integrating seasonality in food web modelling, especially for communities at high altitudes or latitudes, predications about the impacts of climate change may be uncertain. I construct a multi-season model of predator-prey biomass dynamics based on a hybrid dynamical systems (HDS) framework which allows inclusion of both fast (i.e. migration) and slow (i.e. predator-prey) dynamics. Each season is associated with a different stable equilibrium to capture a food web whose topology changes with season. We estimate winter interaction coefficients for the HDS based on summer data from 1993 to 2018 to generate long-term time-series which match observed patterns in species biomass fluctuations. I show that multi-season models, compared to models which do not incorporate seasonality, can expose indirect interactions between migrants and residents. Furthermore, I find that seasonality prevents specialist migratory predators from overexploiting available prey potentially suggesting that temporally changing food web topology may stabilize community dynamics. In my third chapter, I develop theoretical tools based on the HDS stability theory in order to study stability using the model I develop in my second chapter for a seasonal community with migrations. These tools accomplish two goals: 1) to separate the contribution of biomass coming from migrants and from residents and 2) define a measure of resilience which applies to systems with more than one equilibrium depending on the length of time spent in that season. I then use historical and projection data from Representative Concentration Pathway (RCP) climate scenarios to estimate summer season length for low, moderate, and high emissions scenarios. Two mechanisms contribute to the stability in seasonal systems. The first is the length of time spent in summer.."--
