Molluscs of Worcestershire - A Sample Checklist
- to give an idea of what the BRC can produce for you

Species name Year of Last Record Number of Records for County This checklist shows how few records have been collected even for the common species which can be found almost anywhere within the county.

Validation of records is one of the bigger problems for a Record Centre, and a checklist like this can give recorders an idea of what may need further checking.

If a recorder identifies a species that is not already in the County list, or only has one or two records, then they should consider getting the specimen checked by someone else with more experience unless they are already classed as expert in this group.

It could be that the local person 'with more experience' would want to refer the specimen onwards for further verification.
