Quality

CBDC does all it can to validate and verify species records, although it cannot accept responsibility for the accuracy of the data provided.

Validation and Verification

CBDC’s policy is to only shares validated and verified data. Validation ensures that records are in a standard format; with Ordnance Survey grid reference, location, recorder and determiner name and species scientific name using a recognised name in the NBN Species Inventory. CBDC staff liaise with the recorder if there are any queries and may ask for evidence such as photographs or specimens.

Verification is the process of checking that the species identification is correct. Verification is undertaken by local referees or county recorders on an annual basis and is supplemented by national experts reviewing CBDC datasets on a more ad hoc basic. For most records verifiers will merely accept the record is plausible based on what is known about the species’ range, life history, habitat preferences, ease of identification and the recorder’s experience.

Rare, protected and non-native/invasive species will be verified as soon as possible after the record has been received.

So we can confirm we have an EGG!!!👏
It was laid yesterday day afternoon when we noticed the female was sitting tight. In the evening the male brought in a fish and the pair changed over! Two more should be laid in the next few days. https://t.co/3GHTGbuyYu

Wood anemones and early dog violets out by the river Wear in Durham now - getting outside and looking for signs of spring at this surreal time seems like the best #NaturalHealthService @BSBIbotany https://t.co/l2KoNthcz8 CumbriaBDC photo
