In Scotland, Marine Protected Areas are areas of sea defined so as to protect to habitats, wildlife, geology, undersea landforms, historic shipwrecks, and to demonstrate sustainable management of the sea. As of December 2018, approximately 22% of Scotland's seas were covered by the Scottish MPA network.
Sites are designated as MPAs under these acts for one of three purposes:
Nature Conservation MPAs are defined to protect biodiversity
Historical MPAs are used to protect sites such as marine wrecks and artefacts
One Demonstration and Research MPA has been defined to test novel approaches to marine management
In addition to the statutory MPAs, five sites are recognised as forming part of the Scottish MPA network, being categorised as "other area based measures": such areas, although not specifically created for nature conservation purposes, are considered to contribute to the protection of marine biodiversity. The makeup of the current network is detailed in the table below:
Management
The lead body for management of the MPAs is Marine Scotland. For nature conservation sites within territorial waters Scottish Natural Heritage is responsible for developing the network and providing scientific advice to Scottish Government on the selection of sites, and providing advice to Marine Scotland on management once sites are designated. The Joint Nature Conservation Committee fulfils this role for sites in offshore waters, and also has a coordinating role for nature conservation in all the UK's offshore waters. Historic Environment Scotland is responsible for historic MPAs. Activities undertaken in an MPA can be managed through voluntary measures, or by implementation of Marine Conservation Orders or Inshore Fishing Orders. Management measures may be in place for all or part of an MPA, and may only apply at certain times of year. Environmental groups have criticised the government for failing to enforce fishing rules around MPAs.
There is one Demonstration and Research MPA, in the waters surrounding Fair Isle. The MPA was designated on 9 November 2016. The aims of this MPA designation are defined as being:
Other area based measures
Proposed NCMPAs
During 2019 SNH commenced a consultation exercise to consider whether four new areas should be designated as Nature Conservation MPAs, with the having closed on 30 August 2019. The four sites being considered are:
Two further Historic MPAs are also proposed as of 2019, with an Historic Environment Scotland consultation exercise having closed on 27 November. The two proposed sites are:
