The BC Butterfly Atlas is a community-based citizen science project aimed at increasing knowledge of the status and distribution of butterflies in British Columbia. It will harness the efforts of both professional biologists and citizen naturalists to document the distribution and abundance of butterflies in British Columbia. Gathering butterfly records from across BC will help identify which species are truly rare and which are more common, provide a snapshot of butterfly populations to which past and future surveys can be compared, and inform efforts to conserve butterflies and their habitats. Results will be collated into a single database and made available on maps on the project website. The project website includes many resources, including a Twitter feed for sightings.
