Marine Phase 1 Intertidal Habitat Survey

This is a dataset compiled of spatially-referenced survey data obtained from different intertidal communities (biotopes) in Wales. Maps include information on biotope location, species composition, access and photographs points. Additional information is recorded as target notes. Further site information, including site descriptions, geomorphology, uses, impacts, target notes and habitat information is held in an accompanying database Intertidal mapped data provides an integrated information resource for Local Authority structure and development plans on the coast and for the consideration of planning applications.


The maps give important regional information about habitat and biotope distribution. They are used in the production and evaluation of Environmental Impact Assessments, assessment of sites as possible Sites of Special Scientific Interest (SSSI), as a basis for the development of sensitivity mapping, and as a baseline for developing monitoring of intertidal features in marine Special Areas of Conservation (SAC). Sites are mapped once and therefore are a 'snapshot' in time. All data has been subject to a validation process. 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 NRW licence.

Lineage

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: marine biotope classification for Britain and Ireland. Volumes 1 and 2. Version 97.06'. Working at a scale of 1:5,000, field survey is based on using a combination of aerial photographs and Ordnance Survey (OS) maps as a template on to which the substratum and biotopes (habitat and associated biological community) are drawn. Features and other information that are not map-able are described in target notes, a site description provides general information on the whole site and further information on biotopes and species are recorded on the survey form.


The mapped outputs of this project are static datasets, however some sites have been revisited after the project is finished. The up-to-date biotope and target note maps is the product that is maintained and made available when requesting this data, metadata detailing changes can be viewed through metadata URI 114453.
