Marine Ecosection classification for coastal and offshore British Columbia. The Marine Ecosections are: Johnstone Strait; Continental Slope; Dixon Entrance; Hecate Strait; Queen Charlotte Strait; Juan de Fuca Strait; North Coast Fjords; Queen Charlotte Sound; Strait of Georgia; Subarctic Pacific; Transitional Pacific; and Vancouver Island Shelf. The British Columbia Marine Ecological Classification (BCMEC) is a hierarchical classification that delineates Provincial marine areas into Ecozones, Ecoprovinces, Ecoregions and Ecosections. The classification was developed from previous Federal and Provincial marine ecological classifications which were based on 1:2,000,000 scale information. The BCMEC has been developed for marine and coastal planning, resource management and a Provincial marine protected areas strategy. A new, smaller level of classification termed ecounits developed using 1:250,000 scale depth, current, exposure, subsurface relief and substrate was created to verify the larger ecosections, and to delineate their boundaries. CRIMS is a legacy dataset of BC coastal resource data that was acquired in a systematic and synoptic manner from 1979 and was intermittently updated throughout the years. Resource information was collected in nine study areas using a peer-reviewed provincial Resource Information Standards Committee consisting of DFO Fishery Officers, First Nations, and other subject matter experts. There are currently no plans to update this legacy data.

NFIS Project Office. This Web services are for forest change products that represents the first wall-to-wall characterization of wildfire and harvest in Canada at a spatial resolution commensurate with human impacts. The information outcomes represents 25 years of stand replacing change in Canada's forests derived from a single consistent spatially-explicit data source and derived in a fully automated manner.

Ecoregions of Yukon, 2014 is an update to the Yukon portion of the 1995 National Ecological Framework (NEF) described in Ecoregions of Yukon (Smith et al 2004). Because of people's familiarity with the 1995 NEF, and its use in management and planning, these ecoregion revisions attempted to retain the 1995 divisions unless there were compelling reasons to change them. In Yukon there were several compelling reasons to revise the 1995 NEF: 1) capitalize on availability of digital inventory and knowledge and improve or adjust the 1995 mapping as necessary, 2) harmonize stratification along jurisdictional borders, 3) incorporate line work updates to the Soil Landscape polygons by Agriculture and AgriFood Canada (AAFC) happening concurrently, and 4) include Yukon revisions in a national update of NEF ecozones across Canada - led by Environment Canada (CCEA 2017). Mapping the ecoregions of Yukon is largely a top-down process and the divisional hierarchy is nested. The lowest level of the hierarchy is the Soil Landscapes of Canada unit (Soil Landscape Component, or SLC). SLCs are organized according to a uniform set of national soil and landscape criteria that are based on permanent natural attributes. SLCs polygons are not published in this release. Ecozones, ecoregions and ecodistricts are subdivisions at the continental scale of climatic zones; attention to physiography increases as map scale increases. There are many reasonable ways to distinguish Yukon ecoregions. Ecoregions are delineated principally on abiotic features, such as bedrock geology, glacial history and physiography, and so are relatively stable (i.e. enduring) over time. While considering changes to the 1995 NEF, the project team continued to recognize major physiographic and climatic distinctions. At the ecozone level the team included a stronger regional climate element and related the ecozone level to the bioclimate framework. The Ecoregions of Yukon concept is used for broad scale management applications. Its structure helps define ecologically relevant management units at various scales. The Ecoregions of the Yukon Territory (Smith et al. 2004) describes Yukon's ecozones and ecoregions represented in the 1995 NEF (ESWG 1995). This reference continues to be a useful and relevant resource the Ecoregions of Yukon, 2014.

Ecological framework maps for the Yukon resulting from the national report "A National Ecological Framework for Canada". Each area can be viewed as a discrete system which has resulted from the mesh and interplay of the geologic, landform, soil, vegetative, climatic, wildlife, water, and human factors which may be present. The National Ecological Framework for Canada is part of the CGDI National Resolution Framework Data. It has been aligned to the National Frameworks, Canada - 1:M scale Hydrology.

Broad Ecosystem Units were mapped using predictive modeling methods from various data sources (ranging from 1:50,000 to 1:250,000 in scale) and are referenced to the CanVec digital spatial framework (1:50,000). Broad Ecosystem Units (BEU) are a level in the Yukon bioclimate ecosystem classification system that represents areas with similar broad vegetation communities, terrain type (soils and topography) within bioclimate zones. Broad Ecosystem Units are described in the accompanying report "Regional Ecosystems of West-Central Yukon, Part 1: Ecosystem descriptions ".The intended application for mapped broad ecosystem units is 1:100,000 or smaller (1:100,000 - 1:250,000 scale) - interpretations derived from the map products should not be applied at more detailed scales, even though the resultant 30m raster map allows users to view results at more detailed resolutions. With new information, boundaries and designations of Broad Ecosystem Units can change. Updates to Broad Ecosystem Units occur only periodically.

Pelagic Marine Ecounits are intended to describe the sea surface and water column. Two variables were selected to derive pelagic ecounits:1. Salinity and 2. Stratification. The British Columbia Marine Ecological Classification (BCMEC) is a hierarchical classification that delineates Provincial marine areas into Ecozones, Ecoprovinces, Ecoregions and Ecosections. The classification was developed from previous Federal and Provincial marine ecological classifications which were based on 1:2,000,000 scale information. The BCMEC has been developed for marine and coastal planning, resource management and a Provincial marine protected areas strategy. A new, smaller level of classification termed ecounits developed using 1:250,000 scale depth, current, exposure, subsurface relief and substrate was created to verify the larger ecosections, and to delineate their boundaries.
