Newt fencing is a term for a wildlife barrier used to keep newts (generally great crested newts) inside or out of a specific area.
Newt fencing can be used as part of a system to trap newts (i.e. pitfall traps or "buckets") within the area it encloses, enabling that area to be cleared of newts in order that a potentially damaging operation can be carried out. It can also be used in conjunction with traps as a sampling method to assess population size. The term newt fencing also has a generic meaning, in that it can be used to describe a barrier fence used in the same way as described above, but where the species of animal involved may be some other amphibian or, perhaps a reptile. Other terms that are used to describe this system of fencing may include temporary amphibian fencing (TAF), reptile fencing or drift fencing
