Abstract

This document describes the procedure used to create a EUNIS level 3 seabed habitat map, integrating data originating from maps from field surveys and the EUSeaMap model. The work aims to create a map that presents the best available information on the distribution of EUNIS level 3 habitats at any location in UK waters. This dataset is required for, among other things, assessments of progress towards networks of marine protected areas (MPAs) in the UK and marine spatial planning.

UK SeaMap integrates data originating from maps from field surveys and the EUSeaMap model, creating a combined survey/model EUNIS level 3 habitat map for the UK. Using the EUSeaMap model, habitat descriptors (excepting Substrate) are calculated using underlying physical data and thresholds derived from statistical analyses or expert judgement on known conditions. The model includes the sublittoral zone only; due to the high variability of the littoral zone, a lack of detailed substrate data and the resolution of the model, it is difficult to predict littoral habitats at this scale.

This map follows the EUNIS 2007-11 classification system where it is appropriate.
