This licence allows you, as the registered person, to intentionally displace water voles by damaging or destroying their burrows. This includes:
removing vegetation back to bare earth in spring and autumn
carrying out a destructive search of water vole burrows after an appropriate monitoring period, after removing vegetation
Intentionally disturbing water voles by displacement is a method of reducing harm to them where work is to take place. Read the licence document on this page for more details.

are for reasons of overriding public interest
If you cannot follow the terms and conditions of this licence, you should apply for an individual mitigation licence or a strategic licence.
