A Range Unit is an administrative area established to assist in the management of the range program. Typically made up of one or more pastures. Generally, one or more Range Units make up a Stock Range

The DND Air Weapons Range dataset is comprised of all the polygons that represent the Air Weapons Range established by the Department of National Defence, Government of Canada, within the Province of Alberta. Air Weapons Range is the area used as a practice and firing range with restricted access provisions and which is owned and operated by the Department of National Defence, Government of Canada.

A Stock Range is an administrative area established to coincide with local livestock association areas. Generally, stock ranges are made up of one or more range units. Stock ranges are found in select areas of the province where applicable; not all areas of the province contain stock ranges

This spatial layer displays Range Tenures (grazing and hay cutting licence and permits) administered by the Ministry of Forests, Lands and Natural Resource Operations. A Range Tenure is an area of Crown rangeland where a Range Act tenure applies. Tenure holders access a defined amount of forage through grazing (measured in Animal Unit Months) or hay (tonnage). Range Tenures apply only to Crown Land. In some cases, digital boundaries may overlap Private Land but these lands are not part of the Grazing area (as described in the legal description). Grazing may overlap waterbodies during drawdown (also described legally in the Tenure documents and where applicable, Range Use Plan). Livestock may graze islands and large bodies of water may act as Natural Range Barriers. March 3, 2023: Updates to the Range Tenure attribute table as described. Please contact Nancy.Elliot@gov.bc.ca if you have questions. To guide your use: 1. Layer contains RETIRED, PENDING, and ACTIVE Tenures (=Licenses and Permits); Select ACTIVE under attribute LIFE_CYCLE_STATUS_CODE to isolate all active tenures (status refers to spatial boundary status - therefore, a spatial boundary must be Retired in the Forest Tenure Administration system to have a status of retired); 2. Unique ID for Polygon is by RAN# in attribute FOREST_FILE_ID. Each tenure has own its RAN# (e.g. RAN07777). Multiple areas (polygons) belonging to the same tenure may have same RAN# with unique map block ids (e.g. RAN07777 A, RAN07777 B) 3. The field SUM_TENURE_ACTIVE_AREA_HA will provide, where LIFE_CYCLE_STATUS_CODE is ACTIVE, the total tenure area in Ha. For single block (polygon) tenures, this will be the same area as the polygon. Where there are multiple blocks, this will be the total sum area of all Active blocks. (Note this does not include PENDING or RETIRED tenure areas. Area is for Approved and Active Tenure boundaries. A block may be Approved but Pending, and therefore is not included). Review data for multipart vs multi polygons 4. AUTHORIZED_USE and TOTAL_ANNUAL_USE are for the entire Tenure; where there are multiple blocks, the total is over all blocks, seasonally distributed through different pastures 3. FILE_TYPE_CODE contains information on the type of Permit: • E01 - Grazing License • E02 - Grazing Permit • H01 - Haycutting License • H02 - Haycutting Permit 4. IF YOU ARE DOING SPATIAL ANALYSIS based on AREA --- Please note that tenures overlap either partially or wholly amongst tenure holders. One area may be shared by more than one Tenure holder and therefore there will be multiple congruent or partially overlapping polygons (multipart). If you want to do SPATIAL ANALYSIS based strictly on area, you must collapse or flatten the data using DISSOLVE so that the polygons are 1:1 with the land base (suggested approach)

Predicted silt percentage (%) at a defined depth range (0–5 cm, 5–15 cm, 15–30 cm, 30–60 cm, 60–100 cm).

Historical Open Range - 1963-1994 is a polygon layer that depicts grasslands and shrublands (originally designated as 'on land deemed with no potential for growing trees'). Data were derived from a (retired) Provincial Forest Cover Polygon dataset which was interpreted from air photos. Photograph and interpretation dates range from 1963 to 1994. This dataset has value as temporal snapshots of ecosystems under siege from human and natural processes. Data is useful for identification and analysis of forest ingrowth into grasslands from fire suppression. Encroachment can shift over time, for example from changing climate and disturbance events, and this data provides one measure of that shift. Data may also inform location of wildfire safety buffers around communities.

Historic placer mining areas in Yukon can be grouped into ten areas: Klondike; Sixtymile; Fortymile; Clear Creek; Moosehorn Range; Stewart River; Whitehorse South; Mayo; Dawson Range and Livingstone Creek. Each area has its own geomorphic setting and depositional history which is related to its glacial history. Several Quaternary glacial advances have been described in Yukon, and these are generally divided into three episodes, commonly known as the pre-Reid, Reid and McConnell, in order of oldest to most recent.Distributed from [GeoYukon](https://yukon.ca/geoyukon) by the [Government of Yukon](https://yukon.ca/maps) .

An Ungulate Winter Range (UWR) is defined as an area that contains habitat that is necessary to meet the winter habitat requirements of an ungulate species. UWRs are based on current understanding of ungulate habitat requirements in winter, as interpreted by FLNR regional staff from current scientific and management literature, local knowledge, and other expertise from the region. UWRs within this set of data are currently in the review and consultation stage of the area designation process. As UWRs are designated they will be moved into the [Approved Ungulate Winter Range](http://catalogue.data.gov.bc.ca/dataset/ungulate-winter-range) dataset.

A Range Pasture is a grazing area enclosed and separated from other areas by fencing or other barriers (e.g. Natural Range Barrier). May be the management unit of grazing land as reflected in a Range Use Plan. Range Pastures are administrative and not legal boundaries.
