Mollusc (marine) data for Great Britain and Ireland - restricted access

Quality Control

Preliminary checking of the distribution maps of the data has been carried out by Jan Light. However, the checking process is ongoing and this should be borne in mind when using the data as they currently stand.

Method steps

1. The data have been collected by members of the Conchological Society as well as a wide range of other amateur and professional sources and are submitted often, but not always on customised recording cards. Recording is still continuing although no publications are expected at present.

Good coverage of the UK has been achieved by marine recording but digitised data are heavily biased towards the English Channel. It should be noted that large holdings covering Ireland and Scotland exist elsewhere and the Society's data is incomplete in these areas.
