Quentin Groom is the lead of the Biodiversity Informatics team at Meise Botanic Garden in Belgium. In this presentation, Quentin wanted to give attendees a sense of biodiversity data, where it comes from, what they want to learn from it, and what the challenges are. He did this in the context of the B-Cubed project (https://doi.org/10.3030/101059592) that aims to contribute to solving some of these challenges and made particular reference to citizen science for the collection of data and the advantages and challenges this presents.
