This dataset was developed as part of the research for a Royal Roads University master's thesis entitled "Assessing the impact of human activities on British Columbia’s estuaries". The dataset includes BC estuary polygons that were conclusively joined to an adjacent watershed and describes the spatial coverage of different human activities within the bounds of the estuary and its upstream watershed. The areas represented by the human activities includes their potential zone of impact and therefore extend beyond their direct spatial footprint. The attribute table lists the spatial coverage of each activity within the bounds of the estuary, as well as the percentage of the estuary/watershed system that is covered by the activity. Further attributes describe the coverage of conservation designations within the estuary/watershed system. Finally, the 'cluster' variable assigns each estuaries to a cluster group with similar distribution and magnitude of zoned threats.
