These's some evidence that red squirrels may be developing resistance to squirrel pox, which is to be expected - providing the species is resilient/prolific enough to survive for long enough - and this is encouraging.
They're quite common where we live in SW Scotland and I'd hate to see them disappear. How do you feel about the proposal to exterminate the greys, assuming it is feasible? I can see it running into PR problems, because greys do have a certain "cute" factor and some people are probably going to be horrified. OTOH, the Forestry Commission used to have a bounty on them and we shot them with scoped air rifles/.22s to earn money for shotgun cartridges, which were a lot more expensive. Of course, this was back in the days before guns were demonised.................
