This dataset shows length weighted connectivity values summarized by hydrologic unit code (HUC) for a provincial stream connectivity indicator that assesses connectivity for aquatic organisms in stream networks. The stream connectivity indicator supports evaluation and reporting on indicator condition over time and provides information to support management of watercourse crossings. The stream connectivity indicator produces an estimate of the average connectivity in a stream network, considering the movement requirements of local species and the locations of watercourse crossings. The indicator is calculated and summarized using hydrologic unit codes (HUCs). Indicator values are calculated at a HUC 6 scale, and summarized for HUC 8 watersheds at four timesteps: 2010, 2014, 2016 and 2018.

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.

Parks Canada’s National Program for Ecological Corridors was initiated to strengthen the network of protected areas across Canada through the creation of ecological corridors. To achieve this goal, Parks Canada sought out to develop tools for a common approach on the scientific and governance aspects of corridor creation and management. The National Priority Areas for Ecological Corridors (NPAECs) were developed using a scientific framework for national-scale prioritization of where ecological corridors are most urgently needed. Improving or maintaining ecological connectivity in these areas will greatly benefit biodiversity conservation and climate change adaptation. The NPAECs were identified based on a methodology that is multivariate, data driven, national in scale, and spatially explicit at a coarse resolution. The Criteria for Ecological Corridors in Canada provide a common approach to ensure ecological corridors are managed and stewarded to maintain or restore effective ecological connectivity, while upholding Indigenous stewardship values. They are derived from the internationally recognized International Union for Conservation of Nature’s Guidelines on Connectivity and adapted to the Canadian context. The NPAECs geographic data layer, the list of datasets used to identify them, the Criteria and their accompanying guidance can be found below. More details and context about both program elements are available on the Program’s webpage (https://parks.canada.ca/nature/science/conservation/corridors-ecologiques-ecological-corridors).

The Nova Scotia Hydrographic Network is an enhanced version of the Nova Scotia Topographic Database's Water Features theme. This dataset includes network spines for connectivity of water flow and various attribution for flow direction, priority of water flow and toponymic objects where applicable.

The purpose of the cartographic data resulting from analyses of the ecological connectivity of natural environments in the St. Lawrence lowlands is to equip users by making it possible to integrate the concepts of ecological connectivity and the quality of the habitat of natural terrestrial environments into conservation issues. It is a knowledge tool for recognizing natural environments of importance for ecological connectivity in the St. Lawrence Lowlands region. This data is the result of research conducted by McGill University and its partners (Apex Resource Management Solutions, Quebec Center for Biodiversity Science and Habitat) on behalf of the Ministry of the Environment, the Fight against Climate Change, and its partners (Apex Resource Management Solutions, Wildlife and Parks) (MELCCFP).**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

Polygon features representing the geographical extent of a source area that contributes water to a drinking water system. A drinking water system is any domestic system servicing anything other than a single-family dwelling, as defined in the Drinking Water Protection Act. Source Area is a broad term used to describe any area that could potentially contribute water to the drinking water system; it does not mean that hydrologic analyses have been completed to determine likelihood of connectivity. These source areas most often represent the entire aquifer extent (for ground water systems) or the watershed upstream from the intake (for surface water systems). This is one of three Drinking Water Sources datasets (along with the DWS - Intakes/Wellheads points dataset, and DWS - Protection Zones polygons dataset). Note: these polygons have unique Source Areas IDs used to relate them to the Intakes/Wellhead points.
