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.

Biophysical or ecosystem mapping is built on the principle that vegetation composition and distribution responds in predictable ways to specific abiotic terrain conditions. Terrain (surficial geology) mapping and subsequent stratification into ecosystem units forms the basis for local-scale biophysical mapping. Biophysical mapping is therefore an integrated system of mapping which describes both terrain conditions (surficial material type, slope, landscape position, drainage and permafrost conditions) and ecological factors (vegetation community and structure, and soil moisture and nutrient regimes).The Watson Lake area was selected for a pilot biophysical mapping project because of imminent resource activities in southeastern Yukon. Local-scale (1:50 000) biophysical mapping was carried out in the 105A/2 NTS map area during 2004 in cooperation with Yukon Environment, Yukon Geological Survey and Cryogeographic Consulting. Analysis of hard copy 1:40 000-scale aerial photographs was conducted to outline preliminary terrain (surficial geology) and ecosystem units. Four weeks of summer field work was then conducted to ground truth the preliminary aerial photograph interpretation and develop a more detailed ecological classification system for southeast Yukon. Following the field season, the corrected mapping was digitized using stereo-georeferenced high-resolution scanned aerial photographs in Microstation Diap Viewer. Subsequent geographic information system (GIS) manipulation was performed in ArcGIS 9.0. Part of the purpose of the project was to develop a methodology for performing biophysical mapping using these technological tools.

STE_SCANNED_MAP_BOUNDARY_SP includes an index of the mapsheet grid location of Soils, Terrain, Ecosystems and related scanned maps (including Agriculture Capability and Climate Capability maps). These maps are intended for on-screen viewing or printing. The majority of the maps have been geo-referenced. Mapping may not cover the whole map grid area. Some maps are interim or draft and may have been superseded. Some files are of related legends and map project text. Associated scanned map boundary attributes describe the project map (project level metadata) and provide a link for downloading the map, plus links to related reports, geo-referenced maps, and GIS digital data available from other sources. ATTENTION - The IMAGE_URL link is only useable by BC government staff. Public users can download the scanned maps by using the ECOCAT_URL link. There is no charge for the scanned map files. Please note that some maps and more recent mapping may also be available in digital GIS format. See - Ecosystem and Terrain Mapping Data Inventory.

The GTC System makes it possible to compile information on land files.contaminated by industrial and commercial activities or by spillsaccidental. This is not an exhaustive inventory, but a compilation of cases brought tothe attention of the Ministry. It also includes information on land that isnow rehabilitated. The thematic layers of contaminated land allowlocate each georeferenced intervention site in the Operations Management Assistance System(SAGO) to which at least one contaminated land sheet is associated.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

Yukon Biophysical Plot locations are derived from the Yukon Biophysical Information System (YBIS) database, which is the Government of Yukon's repository for storing biophysical data . Data contain a combination of site, soil and vegetation information which are collected by multiple agencies to support vegetation inventory, habitat assessment and baseline ecosystem products collected from 1975 - 2018. Data are collected and input into the database using standardized biophysical field forms as per the "Field Manual for Describing Yukon Ecosystems" data collection standards. Data contributors include Government of Yukon, Government of Canada, First Nations Governments, private contractors, academia and the public. Location accuracy of plot data may vary based on the project year and location collection method. YBIS is an active database, which is subject to periodic updates and revisions. Because of this, the onus is on the end-user to ensure that they are using the most current version of the data. Although every effort has been made to ensure the correctness of the data, there still may be errors.

TA_WILDLIFE_MGMT_AREAS_SVW contains the spatial representation (polygon) of the areas under the administration and control of the Conservation Lands Program of the Ministry of Forests, Lands, Natural Resource Operations and Rural Development and designated as Wildlife Management Areas under the Wildlife Act due to the significance of their wildlife/fish values. The view was created to provide a simplified view of this data from the administrative boundaries information in the Tantalis operational system

Biogeoclimatic Ecosystem Classification (BEC) subzone\variant\phase boundaries with percent protected, number of overlapping protected areas and other attributes added as a result of geoprocessing in the Protected Area System Overview (PASO) application. Protected area and park representation by BEC unit provides a small scale ecosystem classification context for natural resource planning processes such as; management plans, land use zoning, environmental risk assessment, landscape analysis, habitat supply, and management of high priority species. Biogeoclimatic subzones are the basic unit of the BEC system. Subzones are grouped into biogeoclimatic zones to create more generalized units, and subdivided into biogeoclimatic variants and phases to create more specific or climatically homogeneous units. For more information on the BEC system see: http://www.for.gov.bc.ca/hre/becweb/. For important warnings about using this data for spatial analysis see the Data Quality section of the metadata

The Hydrogeological Information System (HIS) contains the physical characteristics of wells and boreholes (location, depth, stratigraphy encountered, etc.) mainly from drilling reports transmitted by well drillers for groundwater sampling installations serving private drinking water residences. The geographic coverage corresponds to all of Quebec although most of the data are found in the south of the province. A monthly update is made.SIH data can be useful for hydrogeology professionals, the academic community and a wider audience in order to make interpretations on portions of territory, for example on the depth of the rock in a sector, or to consult more precise points of information such as the description of a specific identified well.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**
