Legal and policy framework

National legislation

In the 1940s nature conservation made it into the statute books with the National Parks and Access to the Countryside Act (1949) which put in place the foundations for the National Parks we value today.

The Wildlife and Countryside Act (1981) (WCA) became the primary legislation in the UK setting out how animals, plants and habitats should be protected as well as placing controls on the release of non-native species. The WCA applies to both terrestrial and inshore waters which are within 12 nautical miles and during devolution it has been updated and translated in Scotland both through the Wildlife and Natural Environment (Scotland) Act (2011) and the Nature Conservation (Scotland) Act (2004).

The Nature Conservation (Scotland) Act sets out a range of steps including a biodiversity duty on public bodies, powers to identify and create sites of Special Scientific Interest (SSSIs) and to enter into management agreements to improve the quality of nature on land, or to restrict certain activities which may be damaging. This legislation led to the creation of the Scottish Marine Wildlife Watching Code Scottish Marine Wildlife Watching Code which is intended to provide best practice advice and guidance on marine wildlife watching and to help minimise disturbance.

International legislation

Over time policy and legislation has been developed to help protect, manage and restore nature. Today Scotland’s conservation framework is guided by policy and legislation developed at an international and European Union level. Some of the most significant pieces of legislation for the protection and management of the marine and coastal environment are highlighted below.

Environmental Standards


There were concerns, with the UK’s departure from Europe in December 2020, that environmental protection in Scotland could fall behind the rest of Europe. The Scottish Parliament however passed a UK Withdrawal from the European Union (Continuity) (Scotland) Act 2021 which came into effect on the 21 January 2021.

The Act gives Scottish Ministers the power to keep devolved laws similar to EU laws or to amend them and ensures that Scottish Ministers and public bodies pay attention to environmental principles when they make policies and legislation. It also led to the establishment of a new public body called Environmental Standards Scotland to monitor both the effectiveness of environmental law in Scotland and public authorities’ compliance with it. The new organisation will have statutory powers, from Autumn 2021, to make suggestions for improving the effectiveness of environmental law and its enforcement.


Scottish Ministers are required when making legislative or policy proposals to have due regard to the guiding principles on the environment. These four principles are:
