BTO relies heavily on the efforts of thousands of committed and skilled volunteers, who take part in our long-term monitoring schemes. The data they collect generate robust and long-term evidence describing changes in the populations of birds and other wildlife, which in turn prompts further research and conservation action. BTO continually innovates to improve survey design and ease of participation, while broadening our supporter base is a key aim for the future.
