Annual monitoring data
A national trend is available from BBS but it is considered that this may overestimate recent increases because of regional biases in sampling effort.
Trend production using SRMS data is currently limited by lack of geographic coverage and survey effort information. A priority for the SRMS is to work with SRMS contributors to (i) obtain information on study area boundaries and coverage and (ii) assess representatives of coverage through matching information from the Bird Atlas 2007-11 data with the aim of producing a national trend in the future.

It is currently not possible to produce regional trends in breeding numbers or productivity for Buzzard as there are too few long-term studies for this species in Scotland, and those that do exist are considered unlikely to be representative of the overall Scottish population. We hope to address this in the future through encouraging more people to take up monitoring for this species.
