Le présent document Zones de végétation du Canada : une perspective biogéoclimatique cartographie la géographie du Canada en fonction des gradients du climat régional, révélés par la végétation potentielle des sites zonaux. Par rapport aux anciens produits similaires à l’échelle nationale, le document Zones de végétation du Canada tire parti des tr...
La Classification nationale de la végétation du Canada (CNVC) est une classification écologique des communautés végétales naturelles du Canada. Fondée sur huit niveaux hiérarchiques, elle offre un cadre normalisé, à l’échelle nationale, de description des modèles de végétation au sein de leurs contextes écologiques à plusieurs échelles conceptuelle...
The Canadian National Vegetation Classification (CNVC) is an ecological classification of natural vegetation communities in Canada. Using eight hierarchical levels, it provides a nationally standardized framework for describing vegetation patterns within their ecological contexts at multiple conceptual and spatial scales. Natural Resources Canada,...
Vegetation zones are geographic areas that reflect the response of upland steady state vegetation to effective regional macroclimate. Vegetation Zones of Canada is a secondary spatial interpretation of some CNVC units at the Macrogroup and Division levels.
A Canadian Arctic-Subarctic Biogeoclimatic Ecosystem Classification (CASBEC) is proposed as a standardized classification approach for Subarctic and Arctic terrestrial ecosystems across Canada and potentially throughout the circumpolar area. The CASBEC is grounded in long-standing terrestrial ecosystem classification theory and builds on concepts d...
Biogeoclimatic ecosystem classification (BEC) is best described as a classification framework that leverages a modified Braun-Blanquet vegetation classification approach to identify and delineate ecologically equivalent climatic regions and site environmental conditions. Vegetation classification is the basis of the BEC framework and underlies the...
The purpose of the EcoVeg classification approach is to describe the diversity of terrestrial ecosystems across the globe and inform decisions about conservation and resource management. The approach provides the scientific basis for the U.S. National Vegetation Classification, Canadian National Vegetation Classification and NatureServe's Internati...
An ecological vegetation classification approach has been developed in which a combination of vegetation attributes (physiognomy, structure, and floristics) and their response to ecological and biogeographic factors are used as the basis for classifying vegetation types. This approach can help support international, national, and subnational classi...
Various arctic terrestrial ecosystems have been sampled and characterized during the summers of 2013 and 2014 on Victoria Island, as well as King William Island and parts of continental Nunavut. Plot sampling has been performed at selected location, by recording vegetation, environmental and soil characteristics on standardized data cards. These da...
Attachments to the "EcoVeg: a new approach to vegetation description and classification"
A vegetation classification approach is needed that can describe the diversity of terrestrial ecosystems and their transformations over large time frames, span the full range of spatial and geographic scales across the globe, and provide knowledge of reference conditions and current states of ecosystems required to make decisions about conservation...
The alliance is "A vegetation classification unit containing one or more associations, and defined by a characteristic range of species composition, habitat conditions, physiognomy, and diagnostic species, typically at least one of which is found in the uppermost or dominant stratum of the vegetation. Alliances reflect regional to subregional clima...
We summarized the scientific basis for EcoVeg, a physiognomic–floristic– ecological classification approach that applies to existing vegetation, both cultural (planted and dominated by human processes) and natural (spontaneously formed and dominated by non-human ecological processes). It provides a framework that can: • describe vegetation types at...
Large-scale ecosystem maps are essential tools for managers of forest-related activities. In British Columbia, the prevailing approach for ecosystem mapping has been to use an expert system that captures expert knowledge in the form of a belief matrix. In this project, a Bayesian network rather than a belief matrix was used in an attempt to overcom...
Background/Question/Methods The U.S. National Vegetation Classification (USNVC) has recently been completely revised through the Federal Geographic Data Committee (FGDC) Vegetation Subcommittee. That committee, representing a partnership between federal agencies, the Ecological Society of America’s Vegetation Panel, NatureServe, and other organizat...

Background/Question/Methods The late 1990s was the start of a decade of renewed interest in vegetation mapping in British Columbia. Maps were being used for a variety of applications including wildlife habitat assessment, plant association representation targets, and site productivity assignment. Concerns over the accuracy of the mapping, especiall...
Gymnosperms are a diverse group of plants with the common characteristic of having a ‘naked’, or unprotected, seed. Historically common, today only about 900 species exist worldwide. Though found in a wide variety of habitats, gymnosperms dominate many northern hemisphere landscapes.
High-elevation, late-successional forests over much of British Columbia are dominated by Engelmann spruce (Picea engelmannii Parry ex. Engelm.) and subalpine fir (Abies lasiocarpa (Hook.) Nutt.). Throughout the range of these forests, however, there is a wide variation in natural disturbance and successional dynamics as influenced by diverse climat...
In comparison to countries with a tradition of vegetation studies, a comprehensive, hierarchical classification of plant communities in the province of British Columbia has not yet been developed. Such a classification is needed for systematic ecological studies and coordinated conservation of vegetation. As the culmination of fifty years of detail...
Since 1975, the British Columbia Ministry of Forests has been systematically developing an ecosystem classification of the province, an area covering 94 million hectares. This Biogeoclimatic Ecosystem Classification (BEC) system provides a framework for resource conservation and management. To date, approximately 250 person-years have been invested...
Most resource professionals in British Columbia recognize the value of ecosystem classification in providing a conceptual framework and common language for organizing ecological information and management experience about ecosystems.
Ecosystem mapping utilizes principles of ecosystem classification in order to provide a permanent record of the loc...
Tabular and multivariate analyses using subsets of 1299 samples of alpine, subalpine, montane, and submontane, zonal, climax vegetation resulted in a revision and refinement of the biogeoclimatic units for coastal Columbia. -from Authors
Resource managers in British Columbia commonly use a system of ecological classification called the Biogeoclimatic Classification system, a hierarchical classification system with 3 levels of integration: local (vegetation and site classifications); regional (zonal or climatic classification); and chronological. -from Authors
Biogeoclimatic ecosystem classification is a system of ecological classification widely used in British Columbia. The system has been expanded by the B.C. Forest Service from the pioneering work of V.J. Krajina and his students. The recognized units result from a synthesis of vegetation, climate, and soil data. The approach to classification is hie...
A classification and field guide have been developed to idenfify the native plant communities with a component of Garry oak (Quercus garryana) in British Columbia. The field guide is to be released in May 2007 as BC Minstry of Forests and Range Technical Report 040. The purpose of this guide is to standardize the use of plant communities in conserv...
