Situated in the Gwich’in settlement Area (GSA), the Rat River is inhabited by anadromous Dolly Varden (Salvelinus malma malma) that are harvested by both Gwich’in and Inuvialuit beneficiaries. The harvest of Dolly Varden from the Rat River occurs during the summer at feeding areas along the coast (by the Inuvialuit) and during upstream migration in the Mackenzie Delta (by both Gwich’in and Inuvialuit). Dolly Varden stocks are co-managed under an Integrated Fisheries Management Plan (IFMP) whose signatories include Fisheries and Oceans Canada (DFO), Gwich'in Renewable Resources Board, Fisheries Joint Management Committee, and Parks Canada Agency. The Rat River Working Group, the co-management body that makes recommendations for harvest levels for Dolly Varden stocks in the GSA, has supported research activities that facilitate implementation of the IFMP, including studies to monitor harvest levels and assess population status. Population studies (e.g., abundance estimates, biological and genetic sampling) and coastal harvest monitoring activities allow for a comprehensive assessment of this stock. The data are used to inform co-management partners on the status of Dolly Varden from the Rat River.

The Environmental Studies Research Fund (ESRF) Regions are legally described in Part I and Part II of the Schedule in the Environmental Studies Research Fund Regions Regulations in the Canada Petroleum Resources Act. This data collection is for illustrative purposes only and includes:• 1 dataset illustrating ESRF prescribed regions 1 to 31 as they are described in the ESRF Regions Regulations.• 1 dataset illustrating the areas where levies are no longer applied to ESRF prescribed regions. These areas include lands that are described in the ESRF Regions Regulations but have since been devolved to the Government of Yukon or the Government of Northwest Territories as part of the 2003 Yukon Devolution and 2014 Northwest Territories Devolution, respectively. Once the Yukon Act and Northwest Territories Act came into effect, lands subject to devolution were no longer considered frontier lands or Canada lands, and therefore no longer subject to ESRF levies under the Canada Petroleum Resources Act. The geospatial extents used in this dataset represent those identified in the Devolution Agreements. Future updates to Part II, section 3 of the Schedule in the ESRF Regions Regulations will reflect the Yukon and Northwest Territories Devolutions.• 3 maps (National, North, South).• 1 table compiling the historical levies for each ESRF prescribed region.Context:The Environmental Studies Research Fund (ESRF) is a research program which sponsors environmental and social studies designed to assist in the decision-making process related to oil and gas exploration and development on Canada's frontier lands. The ESRF is directed by a 12-member Management Board which includes representation from the federal government, the Canada-Newfoundland and Labrador Offshore Petroleum Board (C-NLOPB), the Canada-Nova Scotia Offshore Energy Regulator (CNSOER), the oil and gas industry, and the public. The ESRF is administered by a secretariat which resides in the Offshore Management Division in Natural Resources Canada.Since 1987, the ESRF has received its legislative mandate through the Canada Petroleum Resources Act. The ESRF regions are described in the Environmental Studies Research Fund Regions Regulations. As well, the Canada-Newfoundland and Labrador Atlantic Accord Implementation Act and the Canada–Nova Scotia Offshore Petroleum Resources Accord Implementation and Offshore Renewable Energy Management Act provide legislative direction in the southern ESRF regions.Funding for ESRF is collected annually through levies paid by lease-holding oil and gas companies active in a specific ESRF region. In accordance with the legislation, levies are recommended by the Management Board to the Ministers of Natural Resources and Crown-Indigenous Relations and Northern Affairs for approval. Levies in the southern regions in areas governed by an offshore Accord are subject to final approval by the respective offshore regulator (i.e., the C-NLOPB, or the CNSOER). Levies are calculated by multiplying the levy rate of a region by the number of hectares of land under lease.The ESRF has sponsored studies on biodiversity; environmental effects and monitoring; social and economic issues; ice, icebergs, and ice detection; oil spill research and countermeasures; sea bottom ice scour; sediment transport; Indigenous Knowledge; and waves.

Surveyed Cadastral Framework for Yukon First Nations Settlement Lands and Tetlit Gwich'in Yukon Lands (settlement like) of the First Nations that have ratified their agreements. Settlement land is land identified in a First Nation's land claim agreement as settlement land of the first nation. There are three types of Settlement Land that a Yukon First Nation can own and manage: Category A: ownership of surface and subsurface; Category B: ownership of the surface only; Fee Simple (FS): private ownership. Note: Some surveys for Settlement Lands identified in their agreement are not yet complete therefore there may be parcels identified with the same land claim selection ID. Each Yukon First Nation has one Category A and Category B parcel identified as their adjustment boundary to adjust any changes in land quantum – as described in chapter 15.6. in each Yukon First Nations’ Final Agreement.Distributed from [GeoYukon](https://yukon.ca/geoyukon) by the [Government of Yukon](https://yukon.ca/maps).

This dataset contains area-based management measures that have been recognized as 'other effective area-based conservation measures' (OECMs). It also contains basic information about OECMs, specifically their names, size, objectives, associated prohibitions, and DFO region. Spatial data for OECMs will be evaluated regularly, taking the most recent available information into account. In addition new 'OECMs will be identified over time. Therefore, this dataset may change over time.

These polygons represent areas across the Province where motor vehicles are prohibited or restricted year round or seasonally. These areas were created as a visual representation of the Wildlife Act Motor Vehicle Prohibition Regulations. Under the Motor Vehicle Prohibition Regulation of the provincial Wildlife Act, motor vehicle use on crown land in B.C. may be prohibited or restricted. This data is a summary of the Motor Vehicle Prohibition Regulations, and is intended for general information purposes only. Where there is a discrepancy between these maps and the Regulations, the Motor Vehicle Prohibition Regulations are the final authority. Motor Vehicle Prohibitions (MVP) are put in place for a variety of reasons. MVPs can be used to: * protect habitat * reduce disturbance and displacement of wildlife * provide areas for hunters on foot, bike or horseback to hunt without motorized vehicles present * reduce hunter harvest while maintaining hunting opportunity   Motor vehicles include but are not limited to: * vehicles * ATVs/UTVs * snowmobiles * motorcycles * electric bikes   For full definitions and detailed regulations, visit the Motor Vehicle Prohibition Regulations website (available under Related Links). There are 2 types of motor vehicle restrictions under the Wildlife Act, and all types can be seasonal or year-round. 1. **Motor Vehicle Closed Area** (formerly referred to as Access Management Areas (AMAs): Prohibits the use or operation of a motor vehicle and e-bike. These prohibitions can be for all motor vehicles, or specific to ATVs/e-bikes or snowmobiles. 2. **Motor Vehicle Hunting Closed Area**: The operation of motor vehicles and e-bikes to hunt, transport wildlife, transport equipment and supplies which are intended for or in support of hunting, or transport hunters to and from the location of wildlife is prohibited. These prohibitions can apply to all motor vehicles, or be specific to ATVs/e-bikes or snowmobiles.

Facilities are an oil and gas activity, defined in the Energy Resources Activities Act as a system of vessels, piping, valves, tanks and other equipment used to gather, process, measure, store or dispose of petroleum, natural gas, water or a substance referred to in paragraph (d) or (e) of the definition of pipeline. This dataset contains point features for proposed applications collected through the BC Energy Regulator's Application Management System (AMS). This dataset is updated nightly.
