National Nature Reserves (NNRs)
This spatial dataset contains the digital boundaries of National Nature Reserves (NNRs) in Wales. NNRs represent the very best examples of our wildlife habitats and geological features and can range in size between five hectares to well over 2,000. NNR are declared by Natural Resources Wales (NRW) under the National Parks and Access to the Countryside Act of 1949, or under the Wildlife and Countryside Act of 1981. They are owned or leased by NRW, or the land is held by an approved body, such as a County Wildlife Trust.
Each reserve has a programme of work to manage the site's special features. All of them are also Sites of Special Scientific Interest (SSSI) and may provide places for educational projects, research and management trials. Some reserves require permits to gain access to them. NNRs are designated over a number of years, beginning in 1954 and on going. This data has been checked by NRW staff. The original, individual, declaration paper maps are the legal documents.

This National Nature Reserve (NNR) final boundary dataset is compiled from the individual declaration maps that make up a single NNR. In some cases an individual NNR is made up of one declaration map, whereas others have many separate declaration maps that were registered over a number of years. Initially the individual, declaration maps were produced on paper at 1:10,000 or 1:2500 scales, then in later years created through GIS.
This dataset has been transferred to OS MasterMap 2006 in 2008. With the coming of GIS and its use in government departments and commercial companies mobilising the data in this way, advances the protection of these sites and the efficiency of decision making.
