註釋The main objective of this study was to compare the avian communities of old-growth (over 200 years old) and second growth (40-80 years old) forests and to identify bird species associated with old-growth forests in the coastal rain forests of British Columbia. A secondary objective was to compare these avian communities with those found in deciduous forests & clearcuts to evaluate & contrast how each forest type contributes to avian diversity. Three study areas were established on the mainland near Vancouver, on the Queen Charlotte Islands, and on Vancouver Island. Diversity & abundance of birds was estimated with the point count method and vegetation attributes were measured in a quadrat at the centre of each point count. Results presented show the significant differences in species diversity, including richness & evenness of bird communities, between the areas studied and between old- & second-growth forests.
