Protected Species Licences

Protected Species Licences

A wide range of plant and animal species are protected by law, and any development or other activities which may adversely affect these species are likely to be subject to the issue of a licence. These can range from ‘derogation licences’ issued by the Welsh Government with respect to ‘European protected species’ such as bats,…
