Marie : Ontario Forest Research Institute. This book was released on 1998 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecoregionalization systems used in resource management stratify terrestrial or aquatic ecosystems and attempt to simplify ecological complexity. They provide an ecologically based alternative to arbitrary administrative planning units and a logical basis for forest resource & protected area planning, assessing biodiversity, monitoring ecosystems, and stratifying sample areas for research. This report examines the regional-level units of the three ecoregionalization systems available for Ontario: Hills Site Regions (Hills, 1959); Terrestrial Ecoregions of Ontario (Wickware & Rubec, 1989); and Revised Terrestrial Ecoregions (Ecological Stratification Working Group, 1995). The objective is to quantify these systems using a multivariate set of geoclimatic variables and to determine the effectiveness of these systems in stratifying different ecological conditions in the province. The report provides descriptive statistics & principal components analysis of each regional unit, compares multivariate distances & geologic similarity among units, and examines gradients of geoclimatic variables across unit boundaries. Strengths & weaknesses of each system in delineating groups of variables (temperature, precipitation, geology, terrain) are discussed along with the implications for using existing systems & future ecoregionalization development.

Download or read book Ecology of a Managed Terrestrial Landscape written by Ajith H. Perera and published by UBC Press. This book was released on 2011-11-01 with total page 355 pages. Available in PDF, EPUB and Kindle. Book excerpt: The growing popularity of the broad, landscape-scale approach to forest management represents a dramatic shift from the traditional, stand-based focus on timber production. Ecology of a Managed Terrestrial Landscape responds to the increasing need of forest policy developers, planners, and managers for an integrated, comprehensive perspective on ecological landscapes. The book examines the "big picture" of ecological patterns and processes through a case study of the vast managed forest region in Ontario. The contributors synthesize current landscape ecological knowledge of this area and look at gaps and future research directions from several points of view: spatial patterns, ecological functions and processes, natural disturbances, and ecological responses to disturbance. They also discuss the integration of landscape ecological knowledge into policies of forest management policies, particularly with respect to Ontario's legislative goals of forest sustainability. Ecology of a Managed Terrestrial Landscape is the first book to describe the landscape ecology of a continuously forested landscape in a comprehensive manner. It is written for instructors and students in forest management, wildlife ecology, and landscape ecology, and for forest managers, planners, and policy developers in North America.

Download or read book Deriving an Eco-regional Framework for Ontario Through Large-scale Estimates of Net Primary Productivity written by Band, Larry E. (Lawrence E.) and published by Sault Ste. Marie : Ontario Forest Research Institute. This book was released on 1999 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: The focus of this study was to estimate the distribution of ecosystem productivity in Ontario at the provincial scale and to explain the nested patterns of productivity based on geoclimatic variables. The study approach, called the Regional HydroEcological Simulation System, uses remote sensing data, geographic information systems, hydroecological simulation modelling, and spatial statistical analysis to simulate forest ecosystem processes at high resolution across a range of Ontario landscapes. The techniques developed were used to partition the province into distinct, ecologically consistent, nested zones, where geoclimatic controls explain much of the variance in productivity at the largest spatial scales and where local landforms & soils control productivity at progressively smaller spatial scales.

Download or read book Global to Local: Ecological Land Classification written by Richard A. Sims and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 619 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecological Land Classification (ELC) refers to the description of land resources at a range of spatial resolutions (i.e. global to local) and for a range of purposes or values. The emerging science of ELC is in fact a very carefully integrated blend of vegetation and earth sciences, climatology, cartography and ecology with a range of new technologies and methodologies including computer-based geographic information systems, remote sensing and simulation modelling. This publication defines the current `state-of-the-art' of ELC. It provides particular insight into the role of ELC in current and future forest resource planning and management, and emphasizes its application and usefulness at various spatial scales, for a variety of geographic locations, and under a range of management scenarios/constraints. The book is an invaluable and substantial reference source about the current trends in ELC and will be of particular value to ecologists, foresters, geographers, resource managers, wildlife biologists, GIS and remote sensing specialists, educators and students.

Book excerpt: This volume represents a first attempt at holistically classifying and mapping ecological regions across all three countries of the North American continent. A common analytical methodology is used to examine North American ecology at multiple scales, from large continental ecosystems to subdivisions of these that correlate more detailed physical and biological settings with human activities on two levels of successively smaller units. The volume begins with an overview of North America from an ecological perspective, concepts of ecological regionalization. This is followed by descriptions of the 15 broad ecological regions, including information on physical and biological setting and human activities. The final section presents case studies in applications of the ecological characterization methodology to environmental issues. The appendix includes a list of common and scientific names of selected species characteristic of the ecological regions.

This book was released on 2005 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: Quantification of hydrological processes and water requirements of aquatic ecosystems is required for many projects related to environmental security and efficient water use in agriculture. This also applies to the Asian monsoon region. This paper focuses on the Walawe River basin, located in a semi-arid zone of southern Sri Lanka. The two major reservoirs in the upstream and middle reaches of the river with a total capacity of 486 million cubic meters (MCM) have significantly affected the hydrology of the river, with associated adverse environmental and social consequences.

This book was released on 2005 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: In March, 2004, Water Survey of Canada and the Canadian Society for Hydrological Sciences co-hosted a workshop in Yellowknife to discuss how to improve our community's abilities to predict streamflow in the Mackenzie Valley and similar cold regions of Canada. The workshop's objectives were to: 1) provide outreach to practitioners of the results of recent studies in cold water regions hydrological regimes in the context of predicting streamflow; 2) assess "state of the art" techniques to predict streamflow in ungauged basins in northern landscapes, and; 3) define technical needs and recommend a research agenda that can deliver these over the next decade. This book summarizes presentations by invited speakers on the subjects of: statisical hydrology and hydrometric network planning; cold regions hydrological processes; application of hydrological models to cold regions; and advances in distributed hydrological modelling.
