We have similar problems in Scotland with Roe deer eating our gardens, but the biggest problem is the Red deer population. There is an organisation called The Red Deer Commission, which conducts a census, and culls if necessary when numbers get too high. However they rely on figure supplied by sporting estates, which rely on the income from hunters to keep them solvent. So do you think they are going to list every last animal on their property, so's the commission can say, 'you've got too many'? Of course they won't! So numbers are too high, many are killed on the road, [and cause the death of some drivers] while the remainder are in poor condition, because there's not enough natural grazing to go round. So as long as sporting estates are valued on the basis of how many stags they produce in a shooting season, the lies will go on.
