Population trend graphs

Graphs are available for the UK, individual countries and English regions.

It is possible to calculate trends for English regions due to the high level of coverage and therefore, larger sample size for many species. Unfortunately, this is not possible for Scotland, Wales or Northern Ireland at present. The counties contributing to each region are displayed in the table below.

On each graph, the dark green line is the smoothed trend, the blue dots are the unsmoothed trend, and the pale green line is the upper and lower 95% confidence limits of the smoothed trend.
