What is a BioBlitz?
A BioBlitz is an event where scientists, naturalists and members of the public work together to find as many species as possible within a set location and over a defined time period – usually 24 hours.
Interested in running your own BioBlitz?
OPAL and the Marine Biological Association (MBA) have produced a free BioBlitz guide packed full of useful tips and guidance.
We've also compiled advice on recording, sharing data, and working with the media.
OPAL BioBlitzes - what have we discovered?
Wembury Bay, Devon
More than 1,000 people took part and we found 823 species, including a moth never seen before in Devon.
Alexandra Palace, London
This was London's first 24-hour BioBlitz and the event helped the venue apply for nature reserve status.
Take part in organised bioblitzes around the UK and see how many species you can find in your local area.
