This is a dataset compiled of spatially-referenced survey data obtained from different intertidal communities (biotopes) in Wales. Maps include information on biotope location, target note location, access and photographs points locations. Sites are mapped once and therefore are a 'snapshot' in time. Survey methodology is based on 'Handbook for Marine Intertidal Phase 1 Biotope Mapping Survey'. Biotopes are based on the JNCC report `Marine Nature Conservation Review. The data available to the public under an Open Government Licence has some information redacted. An un-redacted version can be requested and may be provided under licence.
