Hedgerows
The Hedgerows Regulations 1997 [http://www.legislation.gov.uk/uksi/1997/1160/made] came into force under Section 97 of the Environment Act 1995 [http://www.legislation.gov.uk/ukpga/1995/25/contents]. The regulations allow the planning authority to protect 'important' countryside hedgerows by controlling their removal through a system of notification. Hedgerows within a garden or forming a garden boundary are not covered by this legislation.
