The Big Rock Pool Challenge, run by The Rock Pool Project, invites people across the UK to be citizen scientists starting with the simple act of exploring a rock pool. It’s a fun way to foster local communities that connect with their coastal environment.
The Challenge combines hands-on discovery with digital engagement, where participants record their finds on our app and on iNaturalist during a 90-minute BioBlitz. By doing so, we generate accessible biodiversity data while learning species ID in a fun way. Each species also has a rarity score based on UK records, and at the end of the BioBlitz, we will see who’s got the highest score!
