Trends

Overall the SRMS aims to produce national (Scottish) trends that are fully representative of the Scottish populations of each species, and to then produce regional scale trends.

The SRMS has produced trends for raptors in Scotland based on SRMS data for the period 2009 to 2018.

Trends cover breeding numbers and productivity (breeding success, clutch size, brood size and the number of fledglings) at national and regional (SRMS Region and Natural Heritage Zones) levels for 14 species (13 raptors plus Raven) that breed regularly in Scotland.

We have produced a report which summarises the trends we have been able to produce and points readers to where they can find more detail on this website.

A range of accounts summarising the trends are available:

  • Parameter Accounts – one per parameter (e.g. number of breeding pairs, breeding success, clutch size, brood size and the number of fledglings) – allowing users to readily compare trends for different species and region combinations.
  • Species Accounts – one per species – allowing users to readily compare trends for different parameters across regions.
  • Regional Accounts – one per region (SRMS Region and Natural Heritage Zones) – allowing users to readily compare trends for different parameters across species within any specific region.

Trends can be explored interactively here.
