Head of Surveys
The Surveys Team at the BTO runs most of its large-scale bird surveys, including the Wetland Bird Survey, Breeding Bird Survey, BirdTrack, Waterways Breeding Bird Survey and Heronries Census. In addition, Dawn also maintains and coordinates the Regional Network, BTO's network of volunteer Regional Representatives. She also has responsibility for Regional Conferences.
The Surveys Team organises volunteer-based surveys to collect the data that are core to the BTO’s work on bird populations, including population estimates, trends and distribution. Dawn has a long-term interest in migration and movements of birds and population dynamics and was the Atlas Coordinator for Bird Atlas 2007–11. Dawn is Secretary of the European Bird Census Council and Chair of the Rare Breeding Birds Panel.
