‘Bio’ means ‘life’ and ‘Blitz’ means ‘to do something quickly and intensively’. Together they make ‘BioBlitz’, a collaborative race against the clock to discover as many species of plants, animals and fungi as possible, within a set location, over a defined time period (usually 24 hours).
Below is a guide which has been designed to support the running of BioBlitzes and similar wildlife events in the UK. It is aimed at those running a large-scale event but a BioBlitz doesn’t have to be big to be successful.
You can download the Guide to Running a BioBlitz here.
The guide has been produced by Natural History Museum, Bristol Natural History Consortium, Stockholm Environment Institute, York and the Marine Biological Association.

There is a much simpler guide on the iNaturalist website for those who want to conduct their own BioBlitz perhaps in your garden, yard or even plant pot. They also have an app which makes it easy to identify the species you find by taking a photo and using your smartphone or your computer to get help with any plant or creature you aren’t sure about. You can also look on their map which shows what sightings have been reported close to where you live.
