Marine Biology Société Jersiaise

The Jersey Marine Life Database

The MBS maintains a computer database of over 95,000 records covering 3,200 local marine species and habitats. It is the largest marine biology database in the Channel Islands and has records dating back to the early nineteenth century. The database receives several thousand new records a year and is publicly accessible through the Jersey Biodiversity Centre.

All the records gathered during our research and seashore visits are entered into the database and the MBS has data sharing agreements with other organisations including Jersey Seasearch, Ifremer, the Conchological Society and others. In 2013 the MBS developed their own smartphone app for seashore recording which members can use to record over 200 records an hour. This app is extensively used for habitat mapping and has since been adopted by other local organisations for their recording purposes.

The database is used for species, habitat and general biodiversity monitoring as well as for habitat mapping and highlighting potential issues. It was through the database that the MBS identified two Jersey sites for the minute and exceptionally rare molluscs Truncatella and Paludinella and managed to get one of the colonies saved from imminent destruction.

The database is being developed to become part of a ‘traffic light project’, the aim of which is to provide a conservation status (red, amber or green) for all of Jersey’s known marine species. As with a similar project run by Birds on the Edge, this will help identify those marine species that are most at risk.
