British Columbia Breeding Bird Atlas

For the past five years, members of the BVN have collected information for the British Columbia Breeding Bird Atlas. The following is extracted from the British Columbia Breeding Bird Atlas website:

How do Breeding Bird Atlases work? Atlases http://www.birdatlas.bc.ca/are grid-based — a province or other geographic region is divided into atlas “squares” (in Canada this is usually 10 km square blocks), which volunteers then go out and systematically survey, square by square, for evidence of breeding birds. These grid-based atlases differ from the distribution maps found in your favourite field guide because they represent a “snap-shot” in time, rather than a compilation of historical records, and present information on a fine enough scale that even small changes in breeding bird distribution will be apparent in the future.

What are the final products? Most Breeding Bird Atlases have produced a final hard-copy publication describing where birds breed using maps and text (some previous publications are listed on the North American Ornithological Atlas Committee website). Increasingly, Atlas datasets are published as web-based databases equipped with interactive mapping and data summary tools. Participants and the public not longer have to wait for project completion to see results, instead Atlas progress, species occurrence and survey coverage can be tracked in real time over the course of the project.

Why are Atlases critical to conservation? Atlas projects have both immediate and long-term applications. They provide frameworks for monitoring long-term changes in biodiversity across large geographic areas, which can in turn be related to changes in climate, habitat and land-use. They are unique in their ability to generate current and truly comprehensive inventory information, which greatly improves our understanding of what species occur where, in which habitats and in what numbers. This information feeds directly into conservation planning, management and policy-making, from identifying conservation priorities and areas of critical habitat, to assessment and recovery of species at risk, and helping to keep common birds common. Lastly, the participation of large numbers of volunteers brings different communities together with a collective interest in natural history, fosters a keens sense of environmental stewardship, and encourages hundreds of people to get out and actively enjoy nature.
