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.

The Broad Ecosystem Inventory (BEI) Classification provides broad regional information about the distribution of ecosystems throughout the province and the value of these ecosystems to wildlife. This is done in order to facilitate the use of wildlife information in broad provincial and regional land and resource planning initiatives. Broad Ecosystem Units are mapped based on imagery of the provincial land base generally captured at a scale of 1:250,000. BEI mapping represents forest conditions from approximately 1995 to 2000. The BEI Classification was used to produce wildlife habitat capability and suitability mapping following Provincial Wildlife Habitat Ratings (WHR) Standards (Resource Inventory Committee 1999). Habitat classifications were based on BEI units. BEI units were evaluated and rated to determine the habitat potential (capability) and current habitat conditions (suitability) for selected dry forests and grassland birds within each seral stage within each Broad Ecosystem Unit (and related site modifier variation) within the framework of Ecosections and Biogeoclimatic Sub-zone/Variants for their ability to supply the species’ necessary life requisites. The data represented by the habitat capability and suitability maps for this project was obtained from a team consisting of a bird species expert, a habitat expert, and a data manager. A regional expert review was conducted in September 2002 involving Species at Risk Biologists, Habitat Biologists, and Wildlife Biologists from the Cariboo, Thompson, Okanagan Regions.

Habitat classifications were based on BEI units. BEI units were evaluated and rated to determine the habitat potential (capability) and current habitat conditions (suitability) for selected wild ungulates and furbearers within each seral stage within each Broad Ecosystem Unit (and related site modifier variation) within the framework of Ecosections and Biogeoclimatic Sub-zone/Variants for their ability to supply the species’ necessary life requisites. Regional Wildlife and Habitat biologists, technicians, Forest Ecosystem Specialists, and consulting species experts provided species habitat ratings for each region of the province. Wildlife habitat capability and suitability mapping was completed for the following wild ungulates and furbearers: Northwestern Moose, Alaskan Moose, Shiras' Moose, Bison, Rocky Mountain Elk, Roosevelt Elk, Columbian Black-tailed Deer, Rocky Mountain Mule Deer, Sitka Black-tailed Deer, White-tailed Deer, Dakota White-tailed Deer, Northwestern White-tailed Deer, Boreal Woodland Caribou, Mountain Woodland Caribou, Northern Woodland Caribou, Lynx, Bobcat, and American Badger. Habitat mapping followed Provincial Wildlife Habitat Ratings (WHR) Standards (Resource Inventory Committee 1999).

Ecodomains are areas broad climatic uniformity, defined at the global level

Ecodivisions are areas of broad climatic and physiographic uniformity, defined at the continental level.

This dataset contains the Great Lakes Shoreline Ecosystem (GLSE) inventory, which is a geospatial digital inventory of: * ecosite polygon mapping * field survey calibration points * associated ground level ecological data It replaces Great Lakes Shoreline Ecosystem mapping products versions 1.0 and 2.0. It is an update to those products and includes the data and information contained in them but now includes data and information for the entire Canadian side of the Great Lakes shoreline including connecting channels, from the land to water or wetland interface to two kilometers inland. Mapping and ground sampling adheres to the Great Lakes Shoreline Ecosystem classification system, (Lee et. al., in prep.) which is a detailed ecological classification and surveying method.

This resource documents a dataset of epifauna occurrences collected in 2021 during The Knowledge and Ecosystem-Based Approach in Baffin Bay (KEBABB) program developed by the Department of Fisheries and Oceans Canada (DFO) in collaboration with university partners. The overall objective of KEBABB is to characterize the variability and trends in physical, chemical, and biological oceanographic conditions and food webs supporting fisheries in the connected ecosystems of western Baffin Bay and Lancaster Sound. In 2021, DFO expanded the KEBABB program to Barrow Strait (KEBABS-Knowledge and Ecosystem-Based Approach in Barrow Strait), a key productive area of the Tallurutiup Imanga National Marine Conservation Area. The study took place in the Eastern Canadian Arctic (mainly in Baffin Bay, Davis Strait and Barrow Strait). Sampling is done along transects at fixed stations in the study area. Catches are collected with a 1.5 m Agassiz trawl (5 mm mesh net) for 3 minutes bottom-contact time at a target speed of 1.5 knots and with a 3 m benthic beam trawl (6.4 mm mesh net) for 15 minutes bottom-contact time at a target speed of 3 knots. A total of 16 stations were sampled for epifauna in 2021 between 85-850 m depth. Epibenthic invertebrates are identified to the lowest possible taxonomic level and photographed. All unknown specimens are frozen. In the lab, the identifications are validated or refined with the photos and the frozen specimens.The data are presented in Darwin Core and are separated in two files:The “Activité_épifaune_KEBABB_epifauna_event_en” file which contains information about missions, stations and deployments, which are presented under a hierarchical activity structure.The “Occurrence_épifaune_KEBABB_epifauna_en” file that contains the taxonomic occurrences.Further details on sampling can be found in the following report: Pućko, M., Charette, J., Tremblay P., Brulotte S., St-Denis B., Ciastek S., Hedges, K., Kuzyk, Z., Roy V., and Michel, C. 2022.

Terrestrial Ecosystem Information Project Boundaries contains boundaries (study areas) and attributes describing each project (project level metadata), plus links to the locations of other data associated with the project (e.g., reports, polygon datasets, plotfiles, legends). TEI inventories describe the physical and biological attributes of ecosystems. TEI currently includes Terrestrial Ecosystem Mapping (TEM), Predictive Ecosystem Mapping (PEM), Sensitive Ecosystems Inventory (SEI), Terrain Mapping (TER), Soil Mapping (SOIL), Species Distribution Mapping (SDM) and Wildlife Habitat Ratings (WHR) projects. Current version: v11 (published on 2024-10-03) Previous versions: v10 (published on 2023-11-14), v9 (published on 2023-03-01), v8 (published on 2016-09-01)

The Natural Disturbance Type map is based on the Provincial Biodiversity Guidebook (1995) and the current and most detailed version of the approved corporate provincial Biogeoclimatic Ecosystem Classification (BEC) Zone/Subzone/Variant/Phase map (version 12, September 2, 2021) (Data Catalog record: https://catalogue.data.gov.bc.ca/dataset/bec-map). The natural disturbance type classification code is used to designate a period process or event such as insect outbreaks, fire, disease, flooding, windstorms and avalanches that cause ecosystem change and renewal. Natural disturbance type classification and mapping is used for a wide variety of applications in British Columbia. A few examples include: delineation of Natural Disturbance Types for Landscape Unit Planning; delineation of Seed Planning Zones; as an input for Predictive Ecosystem Mapping; reporting on the ecological representation of the Protected Areas Strategy; and as a level in the classification hierarchy for Broad Ecosystem Units. Note that this mapping is deliberately extended across the ocean, lakes, glaciers, etc to facilitate intersection with a terrestrial landcover layer of your choice
