On reflection and much thought this isnt new!!
In the 1950's we got 6d(2.5p)rising I think to 1/-(5p)for each grey squirrel tail handed in to The Ministry of AG n FISH.
We had some long poles for poking out the dreys.
On doing some googleing,there was also a bounty offered (£1 per tail) by a Welsh Wildlife Trust in 1999.which i believe did not meet public approval so frighteng off the Trust.etc.
PS.Scheme was introdused in 1932,and abandoned in 1957,because it was abused.
