Dragonfly records from the British Dragonfly Society Recording Scheme

British Dragonfly Society Recording Scheme

Description

Dragonfly and damselfly records collected and collated by the BDS Recording Scheme (formerly the Dragonfly Recording Network), a part of the British Dragonfly Society, for the period 1800-2019.

This dataset incorporates the whole of the DRN dataset formerly on the NBN Gateway and the more recent records maintained in iRecord. Data for recent years may be incomplete. Unverified records are added only when accepted. It is the Society's intention that the dataset will be updated at least annually.

Geographic Description

Great Britain. All records are provided to NBN Atlas with an OSGB36 grid reference. For records from Ireland please refer to the appropriate CEDaR dataset. Records from the Channel Islands are not included.

Purpose

This dataset represents the curated, accepted records of the BDS. It aims to provide full coverage across Great Britain and welcomes additional contributions via iRecord or otherwise by arrangement.

Data quality

Records are only included after verification and acceptance by a BDS County Dragonfly Recorder. The date of the most recent verification is included in the dynamicProperties term, 'verifiedDate' sub-term. Records of vague taxa above genus level have been excluded. In general, those records awarded 'Accepted - correct' status have photographic or specimen evidence seen by the verifier whereas those awarded 'Accepted - considered correct' do not pass this strict test.

Methods

Field observations with individual counts of Life Stages. Some records are from site monitoring. Where the custom field 'Recorded all species' is set, the recorder asserts having recorded all species seen on that date at that site, not just the interesting ones.
