2011 Royal Society of Wildlife Trusts UK Areas of Additional Pelagic Ecological Importance dataset https://portal.medin.org.uk/portal/start.php?tpc=010_ec8ca3cae386be17507caac1e90fedb3 The areas of additional pelagic ecological importance (APEI) data layer was created from several NGO datasets and two data layers provided by JNCC. These provide some information on areas of pelagic biodiversity around the UK, but are by no means the complete picture and there will, no doubt, be other areas that are equally important but are without any data. It is hoped that these data will complement the Marine Biological Association's 'benthic biodiversity hotspot' information. The purpose of this data layer is to provide additional ecological information to be used alongside existing ecological datasets submitted by JNCC and NGOs and is not to be considered a substitute for these data. As the data used for the APEI layer were at a UK resolution, regional datasets will still be vitally important and need to be used alongside this work. 20101231
