Through the efforts of volunteers participating in British Trust for Ornithology (BTO) surveys, the bird populations of the British Isles have been monitored more effectively and for longer than those of most other parts of the world. This has produced a uniquely rich and detailed body of scientific work. This will help us to understand the complex challenges facing wild birds at a time of great change in the environment.
