Recording Invasive Species Counts.

If you see a mitten crab, A sighting report requires a clear photograph of the individual, the number of crabs seen, as well as the exact location, time and date of the sighting. If you have the iNaturalist app (available on iOS and Android), a useful tool to record any wildlife sightings both in the UK and overseas, you can submit the record directly on the app or via the iNaturalistUK website. You can also upload records to iRecord, which like iNaturalistUK, shares the data with the NBN Atlas, a national biodiversity database.

Alternatively, you can email the Marine Biological Association through dassh.enquiries@mba.ac.uk with your photograph, location, time and date of the sighting and they can record the sighting for you.

By adding these data to national databases, we are able to protect endangered native animals and track the spread which in turn helps to inform management activities and protect endangered native species.
