PUBLISHED RESEARCH

Research involving CWA data has been conducted in partnership with major universities and waterfowl management agencies. Data for research must be gathered in a precise, methodical manner.

Members should know that the main purpose of our data collection is to evaluate program effectiveness. Peer reviewed research provides an additional value to our efforts by generating new scientific knowledge that benefits our understanding of California’s waterfowl.

Below is a partial list of research publications in which CWA data was used. To read a report, click on one of the titles below.
