I know people like to imagine #wildlife in the #ruralidyll, but that is not the case in Britain. Closeness to suburbia, and the relative protection FROM farmers and gamekeepers, as well as the increased surveillance simply by having a lot of people around, to protect from poaching, is the key to success. Release your beaver, lynx, and what have you, in the greenbelts and edges of cities and larger towns for the best chance of establishing populations.
