UK BAP priority terrestrial invertebrate species

A list of the UK BAP priority terrestrial invertebrate species, divided by taxonomic group into Insects, Arachnids, Molluscs and Other invertebrates (Crustaceans, Worms, Cnidaria, Bryozoans, Millipedes, Centipedes) and their occurence in the four UK countries is provided in the table below. In addition, the 'Original UK BAP species' column provides information on whether the species was on the original UK BAP list created between 1996 and 1998, or was added following the review of priority species and habitats (PDF, 1.3Mb) in 2007. All original species have Species action Plans (SAPs), species statements, or are included within grouped plans or statements, whereas there are, as yet, no published plans for the species added following the 2007 review.

Current scientific names and commonly used synonyms derive from the Nameserver facility of the National Biodiversity Network Species Dictionary, which is managed by the Natural History Museum. More detailed information about the distribution and taxonomy of these species can be found using the NBN gateway, and details of current Species Action Plans (SAPs) can be found on BARS.

JNCC have collated already-published information from a variety of sources for all of the UK BAP priority species, to bring these data together into a single report, or 'species account', for each species. All of this information is already available on either the JNCC website, the NBN Gateway, or the BARS website. More detail about the information within the species accounts is available here. Each individual species account can be accessed by clicking on a name in the table below, or through the full list of priority species.

* The occurrences of Agroeca cuprea and Mecopisthes peusi were updated to include Scotland in August 2011 as it was noted that the Spider Recording Scheme and the NBN gateway indicated that these species were present in Scotland.

** Note, however, that the priority species accounts for Agroeca cuprea and Mecopisthes peusi do not contain this most up-to-date information about their distribution in Scotland, as they were created in 2010, and there are currently no plans to update them.
