Infrequently shot places are like that. The creatures have not been "educated". I shoot one location 2-3 times per year at which it is normal to shoot 200-300 each day. If there is an ATV available to remove them, and pit already dug by JCB, then we'll go for 500+. It is actually boring WORK.
I know of one place, near an active USAF base in Suffolk, which is plastered by naïve rabbits and it hasn't been shot for three years that the farm manager knows of. I know of another site in Suffolk, next to a famous inactive USAF base, which is rarely shot ( I used to shoot over it 4-5 times per year) and that is still plastered with virtually tame rabbits, partridge and deer. I know of a farming estate next to a well known RAF base that is again plastered by rabbits etc, yet rarely shot. I know of a "satellite communications centre", cough cough, on the way down to Devon which is very high security and which is never shot for obvious reasons ....resulting again in big bags on a adjoining farm....which is only shot over after harvest and during the Winter. I know of a UK port that is crying out for good shots with an air rifle to shoot lots and lots of pigeons and yet all they require is a simple positive security clearance. I know of two large property management companies who want trustworthy shooters to turn up, when they say so, to shoot large quantities of mainly rabbits, pigeons and rats. I know the owner of two Castles who has a serious bird problem, and for the sake of spending 2-3 hours per week walking around a Castle scaring birds with a low powered air rifle....he gives virtually unrestricted access to his other land for nine months of the year. I can think of umpteen places, from Kent, to Cornwall, Norfolk, Wales to the Highlands of Scotland where large numbers of rabbits are left unhindered...despite there being a law placing a positive duty on the part of landowners to control rabbits.
And do you know something, there are people in Britain persistently moaning that they have nowhere and nothing to shoot! Or is it that they are lazy, want to have their cake and eat it, and aren't prepared to literally JUMP to someone else's tune?
