Method for creating a composite map of Annex I Submarine structures made by leaking gases for Croker Carbonate Slabs cSAC/SCI
(2018)
Duncan, G.
This report details the input data and method used to create a composite Habitats Directive Annex I feature extent map, of Submarine structures made by leaking gases for the Croker Carbonate Slabs cSAC/SCI.

Summary

 
Submarine structures made by leaking gases (hereafter referred to as "submarine structures") are listed for protection under Annex I of the Habitats Directive (92/43/EEC1). This means that the UK has an obligation to provide protection for this feature through the establishment and management of Special Areas of Conservation (SACs). To aid in the protection and reporting for this feature and the designation and delineation of SACs, JNCC produces extent maps for the feature where sufficient data exist.
 
Existing polygon data from three previous habitat maps was combined with groundtruthing point information, to build up a composite image of “High” and “Potential” Annex I feature within the site.
