Work in progress. The following are complete, though dates and locations of first records of some species are yet to be added or need refining: amphibians, butterflies, Odonata, reptiles. Species lists not yet complete for: fish, Hymenoptera, mammals, moths, orthopteroids, vascular plants. My personal PSL boundary is biogeographical (Britain & Isle of Man). I'm using this geopolitical category (but not including species only recorded in Ireland or the Channel Islands) as it's the closest available approximation (and because everyone else seems to be, so it makes best use of the targets feature).
