Shieldbug & allied species records, from iRecord

Quality Control

The iRecord system has NBN record cleaner rules incorporated within it. In addition, the scheme operates further checks for outlying records (based on species, location and date). The route by which data arrives for verification in iRecord can vary, and comes from recorders with a wide range of experience, but the same verification process is applied to all data and the scheme believes that the dataset provided to NBN is of high quality.

Method steps

1. This dataset includes all records of the relevant species that have been made available for verification via iRecord. Most of these are ad hoc records from volunteer recorders, but may also include data from professionsal surveys and from citizen science projects such as bioblitzes. All data are subject to the same verification checking, which aims to ensure that any record that is unusual (due to time of year, location, or species identified) is queried, and only accepted if supporting evidence (photo, specimen, confirmation from additional recorders) is provided. All records are checked, and the scheme believes that a high degree of confidence can be placed in this data; however, the scheme cannot guarantee that all records which pass the verification checks are correct.
