This project aimed to discover and negotiate access to all existing GIS (electronic) ECM habitat maps, collate the GIS maps and then apply the relevant national classification schemes, develop new nationally consistent habitat classification schemes where not available and conduct quality assurance and document the national map series. The ECM national habitat map series consists of two main groups of information products: 1. a series of three national habitat maps based on the collaboratively developed national intertidal/subtidal benthic (NISB) habitat classification scheme: 2. four products covering the remaining habitat types of dune, vegetation, estuaries, coastal wetlands and shorelines (beaches).
