Contract to identify whether persistent areas of harbour
porpoise and bottlenose dolphin are supported by available
JNCC is seeking to establish a contract to support the UK’s
Natura 2000 network:
With a view to identifying areas for harbour porpoise and
bottlenose dolphin that may be considered to represent SACs with
these species as qualifying features.
The work will build on a previous JNCC project ‘Analysis
of harbour porpoise sightings data in relation to area-based
conservation’ produced by M. Bravington, D., Borchers, & S.
Northridge. Bravington et al (2002) which used the data
contained within the Joint Cetacean Database (JCD) to identify
persistent areas of high usage for the species. It concluded
that no persistent areas of high harbour porpoise density were
found, but recommended the following:
- Investigate further the possible hotspots in the Irish Sea and
off Eastern Britain.
- Develop and apply methods that address the deficiencies
highlighted in this analysis, to make optimal use of the data to
Since the 2002 analysis, many additional surveys from a wide
variety of sources have been undertaken and statistical analysis
techniques have evolved. The Joint Cetacean Protocol (JCP) was
developed to bring these datasets together. The JCP data set
comprises 38 data sources with data from at least 542 distinct
survey platforms (ships and aircraft) representing over 1.05
million km of effort covering a 17 year period from 1994-2010. The
data providers include government funded work such as the Small
Cetaceans in the European Atlantic and North Sea (SCANS) and
Cetacean Offshore Distribution and Abundance in the Offshore
Atlantic (CODA) surveys and the European Seabirds at Sea (ESAS)
surveys; surveys undertaken by NGOs and academics; and also work by
industry (e.g. in relation to potential renewable energy
installations in UK waters). A robust analysis of this dataset is
The Annex A document provides more detail on the background to
the proposed project and further details on the expected outcomes.
The results will be used by JNCC and the other Statutory Nature
Conservation Bodies to inform their advice on the possible
designation of Special Areas of Conservation for harbour porpoise
and bottlenose dolphin.
