An Ecological Framework for Resource Management in British Columbiaers and managers, depending upon their management objectives, use ecological information at different scales, from the very broad regional level to the local or site-specific level. The Ecoregion Classification and the Biogeoclimatic Ecosystem Classification systems provide the means for resource ma

Land District, Ecophysiographic Units and Areas: The Landscape Mapping of the Ministère Des Ressourcthe mapping of land districts, which provide a physiographically-based territorial reference system. The land districts have an average surface area of between 100 and 300 sq km. Since its inception, the department has further refined the methodologies and standardized the results. The current metho

Application of the USDA Forest Service National Hierarchical Framework of Ecological Units at the Su-New York region. A top-down, map-overlay approach was used to map sections and subsections. Where available, landscape level units (LTAs) were aggregated and evaluated to supplement the subsection mapping. A regional collaborative effort was undertaken to counterbalance the shortfalls of a purely m

Development of Ecological Land Classification and Mapping in Support of Forest Management in Northeroundland was initiated to support the local forest management activities. The method adopted here is a modification of the Canadian Committee for Ecological Land Classification’s (CCELC) system, and it applies various levels of mapping to uniform areas based on geomorphology, soils, vegetation, clim

Classification of Local- and Landscape-Scale Ecological Types in the Southern Appalachian Mountainsdform, soil, and vegetation components using multivariate techniques. Elevation and several topographic and soil variables were highly correlated with types of both scales. Landscape ecological types based only on landform and soil variables without vegetation did not correspond with types developed

Since ecosystems themselves are not easily defined in practical terms, ELC is likewise not a trivial concept. Nonetheless, ELC is a prerequisite for ecosystem management and the conservation of biological diversity simply because ecosystems must be d
