Learning: BioBlitzes – searching for wildlife in a race against the clock

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.

OPAL BioBlitzes - what have we discovered?

Wembury Bay, Devon - 2009
This was OPAL's first BioBlitz. More than 1,000 people took part and we found 823 species, including a moth never seen before in Devon.

Alexandra Palace, London - 2010
This was London's first 24-hour BioBlitz. It was a huge success with more than 700 species found, including some unexpected beetles. The event helped the venue apply for nature reserve status.

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.
