"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, Canadian Forest Service (NRCan – CFS) has led the development of the CNVC since it began in 2000, working primarily on forest and woodland communities, and mainly at two levels of the hierarchy, the mid-level Macrogroup and the stand-level Association. CNVC development relies on partnerships with provincial and territorial government agencies for regional ecological expertise and data, and benefits from international collaborations for comparisons with other national classifications. This report introduces the CNVC, including its rationale, history and partnerships; presents the classification framework (hierarchy); documents methods employed to 2018 for the development of types, including information sources and the bioregional expert review process; and describes the products to date, available on the CNVC website (cnvc-cnvc.ca/) and the Natural Resources Canada – Canadian Forest Service Publications website (cfs.nrcan.gc.ca/publications). Developing and maintaining a national classification framework requires considerable resources, and ongoing funding is needed to sustain the effort summarized here"--Abstract, page 2.
