The Big Rock Pool Challenge: National BioBlitz.
Help track invasive, non-native marine species and protect UK coastal wildlife on 17th – 25th May 2025.
This May, join the Big Rock Pool Challenge: National BioBlitz — a week-long nationwide mission to discover, record, and protect marine life, with a special focus on invasive species that threaten our native shores. Utilising the iNaturalist app and a sense of adventure, you’ll help scientists track the spread of non-native species while earning your Rock Pool Discovery Score through our online hub. Whether you’re spotting a beadlet anemone or catching sight of something rarer, every record counts.
Anyone can take part — no experience needed, just curiosity and a love of the coast. Together, we’ll shine a light on the hidden life of our rock pools and build a national picture of how our marine ecosystems are changing.
