Historic Trails of British Columbia
This dataset contains spatial and tabular data on non-archaeological historic trails in B.C. Some of these trails, or sections of trail, are defined or protected under provincial legislation such as the Heritage Conservation Act. Other trails or trail segments are recorded but not legally protected. This dataset represents line feature data (e.g. trail routes).
NCC Greenbelt Limits - 2013
Delimited area of the Greenbelt as of 2013.
Coal Agreements
Coal Agreement feature class contains provincial extent polygon features representing Coal applications, agreements, leases, and licences, with varying term dates and conditions. These applications and subsequent agreements give the holder the right to explore Coal.
NCC Recreational Paths and Trails
Lines representing where recreational pathways, trails, parkways, and forest roads owned and/or maintained by the NCC are located.
Drainage Culverts - 25k
This dataset includes all drainage culverts with a n opening diameter of less than 2 metres. Culverts with a diameter greater than 2 metres are defined as structural culverts and are not present in this dataset.Distributed from [GeoYukon](https://yukon.ca/geoyukon) by the [Government of Yukon](https://yukon.ca/maps) .

Yukon tourism regions
This dataset divides Yukon into 9 tourism regions which are used to track wilderness tourism statistics. Note that the Yukon Vacation Planner divides Yukon into 8 similar tourism regions with somewhat different boundaries.Distributed from [GeoYukon](https://yukon.ca/geoyukon) by the [Government of Yukon](https://yukon.ca/maps) .

Some of these trails, or sections of trail, are defined or protected under provincial legislation such as the Heritage Conservation Act. Other trails or trail segments are recorded but not legally protected. This dataset represents polygon feature data (e.g. cleared areas associated with trails).
Stand Structure Habitat Classes in Mule Deer Winter Range - Cariboo Region
Stand structure habitat classes associated with mule deer winter range in the Cariboo Region.
Widespread genetic similarity between Northwest Atlantic populations of the horse mussel, Modiolus modiolus
Effective conservation planning relies on understanding population connectivity which can be informed by genomic data. This is particularly important for sessile species like the horse mussel (Modiolus modiolus), a key habitat-forming species and conservation priority in Atlantic Canada), yet little genomic information is available to describe horse mussel connectivity patterns. We used more than 8000 restriction-site associated DNA sequencing-derived single nucleotide polymorphisms and a panel of 8 microsatellites to examine genomic connectivity among horse mussel populations in the Bay of Fundy, along the Scotian Shelf, and in the broader northwestern Atlantic extending to Newfoundland. Despite phenotypic differences between sampling locations, we found an overall lack of genetic diversity and population structure in horse mussels in the Northwest Atlantic Ocean. All sampled locations had low heterozygosity, very low FST, elevated inbreeding coefficients, and deviated from Hardy-Weinberg Equilibrium, highlighting generally low genetic diversity across all metrics. Principal components analysis, Admixture analysis, pairwise FST calculations, and analysis of outlier loci (potentially under selection) all showed no independent genomic clusters within the data, and an analysis of molecular variance showed that less than 1% of the variation within the SNP dataset was found between sampling locations. Our results suggest that connectivity is high among horse mussel populations in the Northwest Atlantic, and coupled with large effective population sizes, this has resulted in minimal genomic divergence across the region. These results can inform conservation design considerations in the Bay of Fundy and support further integration into the broader regional conservation network.Cite this data as: Van Wyngaarden, Mallory et al.

Seasonal Movements and Diving of Ringed Seals, Pusa hispida, in the Western Canadian Arctic, 1999 – 2001 and 2010 – 2011
This record contains two datasets: 1. Raw unfiltered geographic coordinates and accuracy estimates of ringed seals tagged in the Western Canadian Arctic and 2. The location estimate from state-space models using a 12-hr time step. In total, 17 ringed seals were captured, measured, weighed, and tagged with satellite-linked transmitters (SDR-10, SDR-16, SPLASH) in June and July of 1999, 2000, and 2010. The tags, manufactured by Wildlife Computers Ltd. (Redmond, Washington, USA), sent data to polar orbiting satellites. Data were then retrieved via the Argos system (Harris et al., 1990). Tags collected and relayed information on movement (geographic positions) and diving data of the instrumented animals.
