Abstract

The Conservation of Habitats and Species Regulations 2010 provide for the designation and protection of 'European sites', the protection of 'European protected species', and the adaptation of planning and other controls for the protection of European Sites. This dataset is made up of 43 datasets showing the extent of features for which our marine Special Areas of Conservation (SACs) are designated and forms part of the advice packages Natural Resources Wales (NRW) prepares for our marine SACs under Regulation 37 (formerly Regulation 33 and 35) of the Conservation of Habitats and Species Regulations. They show the presence of (extent) of features within our marine SACs at the time of site designation against which statutory advice can be given. They also act as a b aseline for feature extent against which changes can be measured during reporting under Article 17 of the Habitats Directive.

Lineage

The Regulation 37 SAC datasets provide the indicative baseline extent and status of SAC features at the time of site designation. They should be used to assess potential impacts of plans and projects and for casework advice. They also form the baseline against which we measure changes in extent during Habitats Directive reporting. Features include: sandbanks which are slightly covered by seawater all the time, estuaries, mudflats and sandflats not covered by sea water at low tide, coastal lagoons, large shallow inlets and bays, reefs, Salicornia and other annuals colonising mud and sand, Atlantic salt meadows (Glauco-Puccinellietalia maritimae), and submerged or partially submerged sea caves. The layers are created by collating records from numerous surveys, monitoring programmes, expert knowledge, and third party providers and then combining them using GIS to produce layers containing points, polygons or lines. The layers are updated when new evidence to inform feature extent becomes available. The original datasets surveys and monitoring events from which the records have been extracted vary widely in dates, going back many decades in some cases. However surveys were undertaken between the dates of 1899 - 2015. This dataset is updated approximately every 6 years.
