Remember it is also legal to shot them for humane dispatch as well, under the Deer Act Amendment 2007.
That only allows for humane dispatch where they have been injured, for example if they've broken a leg, or been hit by a car, stuff like that.
The Regulatory Reform (Deer) (England and Wales) Order 2007
A person shall not be guilty of an offence under section 4(1) or (2) above by reason of the use of any reasonable means for the purpose of killing any deer if he reasonably believes that the deer has been so seriously injured, otherwise than by his unlawful act, or is in such condition, that to kill it is an act of mercy.”
Where section 4 is section 4 of the Deer act, which sets out prohibited methods of taking deer.
Yes..like I said, Humane despatch!!
