|Relative Abundance (No. of Adults)
The numbers of adults reported per species over the period 1990-2015 have been
sorted to show the relative reported abundances of species.
||Relative Distribution (1km Squares)
The number of 1km squares in which each species was reported during 1990-2015
have been sorted to show relative distribution. This doesn't of course imply even distribution of any species - some, such
as the chalk-loving species can only be found in the south.
