Objectifs
The BCCWS has the following specific objectives: to assess the annual changes and long-term trends in population size and distribution of coastal waterbirds in BC., to collect data that contribute to population estimates of coastal waterbird species in BC., and to advance our understanding of the ecology and the effects of human activity on coastal waterbirds in BC.
Méthodologie
Plan d’échantillonnage
In populated areas, sites were set up by coordinator, but in remote, or uncovered areas, participants select their own sites
Méthodes de terrain
Observers count all waterbirds, by species, at regular (2nd Sunday of each month) intervals at specfic locations so that coordinated information on distribution and migration over a broad area can be acquired. Surveys are conducted as close to high tide as possible, and in the same manner each time.
Méthodes d'analyse
Scientific review of data in 2002, annual newsletter
