Mollusc (non-marine) data for the Channel Islands
The records in this dataset are the results of the Conchological Societies non-marine census which has been run since 1876. The dataset includes all digital records held by the Society up to the time of publication. The dataset is an amalgam of the cards that were originally digitised at 10km square as part of the publication of the non-marine mollusc atlas as well as a redigitisation of those records at finer scales and a substantial number of more recent records. All the survey data were collected by members of the Conchological Society. Recording is still continuing although no publications are expected at present. Some older Channel Islands records have been gleaned from various papers.
