CMIST is a peer-reviewed screening-level risk assessment tool for marine invasive species (Drolet et al. 2016). It is a short questionnaire that follows the invasion process from arrival to impact and is designed so an informed assessor can evaluate one species in an assessment area in approximately one day using easily accessible information from internet databases, primary literature, and grey literature. Species can be those with an invasion history in an area or those that are candidates for future invasions.CMIST is score-based and incorporates both likelihood and impact of invasion as well as uncertainty. Questions are general to make CMIST broadly applicable to different taxa, different assessment areas, and different project goals. To date, CMIST has been tested with molluscs, tunicates, crustaceans, and polychaetes introduced or at risk of introduction to three Canadian marine ecoregions (DFO 2009). CMIST has also been successfully applied to non-indigenous freshwater fish in British Columbia with adapted guidelines (T. Therriault, pers. comm.). Upon completion, CMIST produces a risk score adjusted for the assessor’s uncertainty which, combined with information collected during the assessment, can be used to assist in management decisions. For example, in 2015, CMIST assessments were used to identify high risk invaders in three Canadian marine ecoregions (DFO 2016).

The Canadian Heritage Rivers System (CHRS) is Canada's national river conservation program. Established in 1984, the CHRS gives national recognition to Canada's outstanding rivers and encourages their long term management to conserve their natural, cultural and recreational values for the benefit and enjoyment of Canadians, now and in the future. There are currently 42 Canadian Heritage Rivers, 4 are in the Yukon. For more information about CHRS refer to [https://chrs.ca/en](https://chrs.ca/en)Distributed from [GeoYukon](https://yukon.ca/geoyukon) by the [Government of Yukon](https://yukon.ca/maps) .

Tenure Areas are geographic administrative areas named for local features and used to group petroleum and natural gas Land Plats situated within the same local geographic area.

Pipeline installations associated with an oil and gas pipeline activity. Installations include such features as flare stacks, generators, line heaters, pumps, risers, tanks and valves. This dataset contains point features for proposed applications collected through the BC Energy Regulator's Application Management System (AMS). This dataset is updated nightly.

Land authorizations representing the road right of way for road activities. The spatial data includes polygon data for approved and post-construction road rights of way collected on or after October 30, 2006. This dataset is updated nightly.

Offshore Oil and Gias exporation Potential

Spatial data for approved and post construction features for Canada Energy Regulator (CER) related ancillary features and Energy Resources Activities Act (ERAA) associated oil and gas activities collected on or after October 30, 2006. Associated oil and gas activities are related activities which require the use of Crown land and require an authorization under either the Land Act or the Petroleum and Natural Gas Act. The dataset includes polygon features such as campsites, workspaces, deck sites, staging areas, and other temporary disturbances. This dataset is updated nightly.

Land authorizations for areas on which well or facility activities can occur. This dataset contains spatial data collected on or after October 30, 2006. The spatial data includes approved and post-construction land areas associated with well or facility activities. This dataset is updated nightly.

Pipeline installations associated with an oil and gas pipeline activity. Installations include such features as flare stacks, generators, line heaters, pumps, risers, tanks and valves. This dataset contains point features collected on or after July 11, 2016 for approved installation locations. This dataset is updated nightly.
