The list of checklists is available through the Tools menu or can be accessed directly at https://database.bsbi.org/checklists.php
More than 60 Checklists, available for use in DDb queries can be accessed via this tab. They can be downloaded as csv files for use in spreadsheets. To download a checklist, click into it and go to the Items tab. Then click on the download list link.
As used by the DDB, 'Checklists' provide a general-purpose way of grouping or applying attributes to records when running queries. Checklists consist of a set of 'key' values which link to a field (e.g. a taxon name). Each item in the checklist set may optionally have a data value associated with each key.
