The UK only has around 50 species of butterflies (including the Dark green fritillary above) and, after a number of hard years, some are in rapid/terminal decline. There have been the odd success in re-introduction (notably the Large blue from Swedish specimens) but they require careful habitat management along with potential breeding specimens. The latest attempt concerns the Chequered skipper that people are attempting to re-introduce from Belgium into Rockingham forest in Northamptonshire (https://www.theguardian.com/environment/2018/may/17/back-from-the-brink-chequered-skipper-butterfly-takes-to-english-skies-again). I appreciate that the workers wanted to take specimens from roughly similar habitats as the woodland rides they were going to but they could have used Scottish bugs.

In biomass terms humans are pretty puny, accounting for only 0.01% of living things but our impact has been extraordinary (https://www.theguardian.com/environment/2018/may/21/human-race-just-001-of-all-life-but-has-destroyed-over-80-of-wild-mammals-study). Reportedly, 36% of current mammals are humans, 60% are domesticated beasts such as cows, sheep and goats and only 4% (and reducing) are wild species. The situation, in the case of birds, is only slightly less extreme with 70% being poultry (mainly chickens) and 30% being wild avian species. The extinction-impact of humans is evident in the fact that we have already eliminated more than 80% of all wild animals and 50% of plants. We are clearly on a par with the meteor strike that accounted for the dinosaurs.
