It is against the law to remove most countryside hedgerows
without permission, to get permission to remove a hedgerow you
must complete an application form
and send it to your local planning authority. If the
authority decides to prohibit the removal of an important hedgerow
it must let you know within 6 weeks. If you remove a hedgerow
without permission (whether it is important or not) you may face an
unlimited fine. You may also have to replace the hedgerow.
