• Trends are percentage changes, and are marked with an asterisk (*) where the 95% confidence limits of the change do not overlap zero (indicating that there has been a significant change). • Trends for species in brackets are reported with caveats (see pg11). • The sample is the mean number of squares per year on which the species was recorded during 1994–2014.
