Nom du projet : Relevé des oiseaux aquatiques côtiers de la Colombie-Britannique

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.

Statut : Active

Première année : 1999

Années (commentaires) : ongoing

Saison(s) et fréquence : monthly with an emphasis from September to April

Fréquence : Monthly

Région géographique couverte : Coastal British Columbia

Type(s) d'habitat : all coastal habitats

Principales espèces couvertes : waterbirds

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.

Format des données : Data reported on survey forms. Computerized database maintained at Bird Studies Canada office in CWS Pacific and Yukon Region Delta office.

Taille d'échantillon : 322 sites - coverage varies year to year

Résultats : Scientific review of data in 2002, annual newsletter

Sources de financement : Environment Canada, Habitat Conservation Trust Foundation, looking for other sources

Applications des données : Used for deriving trends in waterbird populations and locating important staging areas

Utilisateurs de l'information : Waterbird research biologists, planners, resource managers

Évaluation environnementale : Yes; on the themes of coastal regions
