Collation of EUNIS habitat maps
The Data page summarises the composite datasets
that JNCC maintain and where to find them, below is a
description of the three main EUNIS-based data products published
EUNIS habitats: maps from surveys
To aid the conservation work of JNCC and the statutory
nature conservation bodies, JNCC collates and
standardises habitat maps in the UK and makes them freely
available to view and download online. These may be
created by a range of public, private and not-for-profit
organisations and exist at a range of spatial, temporal and
thematic scales. When possible, habitat maps are standardised
by translating into the EUNIS habitat classification system and
formatting according to the MESH Translated Habitat Data Exchange
Format. From this standard classification system we are
then able to extract data related to priority habitats such as
Habitats Directive Annex I habitats and OSPAR threatened
and/or declining habitats.
These maps are available to view and download as a single
composite data set from the EMODnet Seabed Habitats interactive
map. Click on the map to the right to go straight to this layer

EUNIS habitats: broad-scale full-coverage model
The collection of local habitat maps from surveys (described
above) has a patchy
distribution and a variety of scales. To allow national and
regional assessments to be made, JNCC has taken part in and led on
projects to produce broad-scale EUNIS habitat maps that cover the
entire UK seabed that are consistent in spatial and thematic scale.
The method overlays multiple models of physical parameters such as
light, energy and seabed substrate and matches combinations of
physical parameters to physical EUNIS habitat descriptions (levels
3 and 4 of the hierarchy).
The most recent project to produce such a map was phase 2
of the EMODnet Seabed Habitats project, EUSeaMap. Phase 2 (2013-2016) builds on
work completed under phase 1 (2009-2012) to improve the map and
extend its coverage to all European Union waters.
This map and its input data layers are available to view and
download from the EMODnet Seabed Habitats interactive map.

EUNIS habitats: full-coverage EUNIS level 3 layer integrating
maps from surveys and broad-scale models
In some cases, a full-coverage map is required that
displays the best available data everywhere, at the expense of
consistency. The production of such a product showing EUNIS level 3
habitats, as required for Marine Protected Area network
assessments, involved creating a set of rules that selected
the most reliable EUNIS level 3 habitat data at any
location, be it from a map from a survey (described at
the top of this page) or the latest
broad-scale predicted map, EUSeaMap (described above). The following documents
provide more information about the approach taken:
