Quite enjoyed reading the project report from VWT on monitoring the Pine Marten in Northumberland between 2017 - 2020. I assumed they'd only be in Kielder, but lots of evidence and sightings elsewhere, in Kidland Forest, even Kyloe crags and, weirdly, Beadnell.

There's quite a bit of research to suggest that pine martens help red squirrels by predating greys
