Join Joss Carr as he discusses his MSc Research Project investigating the data quality of UK invertebrate records on iNaturalist.
iNaturalist is a rapidly growing source of biological records in the UK: In 2024, over 44,000 users generated more than 1.6 million records using the platform. With the number of records generated set to increase into the future, integrating iNaturalist into UK recording systems is essential. As of 2020, iNaturalist records meeting certain criteria have been exported into iRecord, where it is hoped they will be reviewed by verifiers.
For some groups of invertebrates, however, it would appear a large proportion of iNaturalist records are not being reviewed. One explanation for this is that concerns with the data quality of records are leading verifiers to deprioritise iNaturalist as a source. All iRecord verifiers are volunteers with large workloads and limited time, so this may be justified if the data quality of iNaturalist records is indeed lower. However, this has never been quantified.
This research sought to address this, quantifying for the first time the extent of data quality concerns across taxonomic groups of UK non-marine invertebrates. Results suggest that there are indeed systemic data quality issues with iNaturalist records, though the greatest issues in reality are not always the same issues people perceive to be greatest. Many such issues will be fixable through education and outreach to iNaturalist users.
