iNaturalist is a citizen science project focused on biodiversity. It has a large community of enthusiasts, of which some are also active in the various Wikimedia communities.
On Sunday at 9:30am during Wikimania I will be hosting an iNaturalist meet-up in front of the event venue, Aula Magna. Once we are all assembled, we will head over to the nearby Stora Skuggan nature preserve (approximately 1 mile / 1.5 km from the event venue) where we can look for plants and animals to photograph and have discussions about how to further collaboration between iNaturalist and the Wikimedia projects. We should return before lunch time.
