What is a Bioblitz Battle?

A bioblitz is an event that focuses on finding and identifying as many species as possible in a specific area over a short period of time, usually 24 hours. The Rock Pool Project created the Big Rock Pool Challenge BioBlitz Battle, a90-minute friendly competitive citizen science activity for rock pool enthusiasts. A BioBlitz Battle is a times, team-based competition where participants record species they find in local rock pools using iNaturalist, a popular biodiversity recording app. Every species found returns a score depending on its rarity as recorded in the UK iNaturalist database. This encourages participants to search for a wide variety of species, from the common to the rare, and adds an exciting competitive element.
