Not wanting to mislead anyone, I have looked up section11 and have copied it here:
Section 11 of the Wildlife and Countryside Act 1981 as amended by Schedule 12 of the Countryside and Rights of Way Act 2000 create the offences of setting self-locking snares and snares that cause bodily injury to any wild animals that come into contact with them, or using bows, crossbows or explosives to kill or capture them; using as decoys any live mammal or bird or knowingly cause or permit any of these offences to be carried out, and failing to inspect snares which have been set on a daily basis. It states:-
11(1) Subject to the provisions of this Part, if any person:-
(a) sets in position any self-locking snare which is of such a nature and so placed as to be calculated to cause bodily injury to any wild animal coming into contact therewith;
(b) uses for the purpose of killing or taking any wild animal any self-locking snare, whether or not of such a nature or so placed as aforesaid, any bow or crossbow or any explosive other than ammunition for a firearm;
(c) uses as a decoy, for the purpose of killing or taking any wild animal, any live mammal or bird whatever; or
(d) knowingly causes or permits to be done an act which is mentioned in the foregoing provisions of this subsection,
he shall be guilty of an offence.
11(3) Subject to the provisions of this Part, if any person:-
(a) sets in position or knowingly causes or permits to be set in position any snare which is of such a nature and so placed as to be calculated to cause bodily injury to any wild animal coming into contact therewith; and
(b) while the snare remains in position fails, without reasonable excuse, to inspect it, or cause it to be inspected, at least once every day,
he shall be guilty of an offence.
11(4) The Secretary of State may, for the purpose of complying with an international obligation, by order, either generally or in relation to any kind of wild animal specified in the order, amend subsection (1) by adding any method of killing or taking wild animals or by omitting any such method as is mentioned in that subsection.
11(5) In any proceedings for an offence under subsection (1)(b) or (c) and in any proceedings for an offence under subsection (1)(d) relating to an act which is mentioned in any of those paragraphs, the animal in question shall be presumed to have been a wild animal unless the contrary is shown.
