National nature reserve (Scotland)
The national nature reserves (NNRs) of Scotland are areas of land or water designated under the Wildlife and Countryside Act 1981 as containing habitats and species of national importance. National nature reserves can be owned by public, private, community or voluntary organisations but must be managed to conserve their important habitats and species, as well as providing opportunities for the public to enjoy and engage with nature. There are currently 43 NNRs in Scotland, which cover , or less than 1.5% of the land area of Scotland. They range in size from Corrieshalloch Gorge at 7 ha to Mar Lodge Estate, which covers 29,324 ha. National nature reserve status is an accolade awarded to the best nature reserves in Scotland, and the selected sites provide examples of nationally or internationally important species and habitats. NNRs are intended to showcase Scotland's nature, and as well as being well managed for wildlife they must be managed to provide opportunities for the public to visit and enjoy them. NNRs therefore generally have facilities such as visitor centres and trails to allow visitors to explore and understand the habitats or wildlife they contain. Most NNRs in Scotland are also designated as Sites of Special Scientific Interest. Many also form part of the Natura 2000 network, which covers Special Protection Areas and Special Areas of Conservation. Additionally, some of the NNRs are designated as Ramsar sites. History National nature reserves were first created under the National Parks and Access to the Countryside Act 1949. In 1996 the public body responsible for Scotland's natural heritage, Scottish Natural Heritage (SNH – since renamed NatureScot), undertook a review of NNR policy that took account of the availability of other designations conferring legal protection, such as site of special scientific interest, special protection area and special area of conservation. It was determined that NNR should possess four attributes: Primacy of nature – conservation must be the primary land use within a NNR: "nature comes first". National importance – the conservation value of the habitat, species or feature must be such that it is of national importance that the site be managed as a reserve. Best practice management – NNRs must be well managed. Continuity of management – a long-term view is required. Additionally, it was determined that NNRs should be managed for at least one of three purposes: Raising public awareness. Specialised and pro-active management. Offering opportunities for research into the ecology and its management. Between 2000 and 2003 the existing NNRs were reviewed against these criteria. Prior to 2004 there were 73 national nature reserves in Scotland, however a number have since been de-designated. New NNRs have also been designated, such as the National Trust for Scotland's Glen Coe and Mar Lodge properties, which were both designated NNRs in 2017. Since 2012 governance of the NNR designation in Scotland has been through a partnership group, comprising representatives of existing reserve management organisations and community land groups, chaired by NatureScot. NatureScot remains responsible for the statutory declaration of national
