What is a BioBlitz?

A BioBlitz is an exciting race against the clock.

Over a 24 hour period, scientists, naturalists and members of the public work together to find as many species as possible within a defined location.

Not only is a BioBlitz great fun, but it also collects useful biodiversity information which can help conservation.


BioBlitz 2016

BioBlitz 2015

As CEDaR is celebrating its 20th Anniversary this year, we have teamed up with one of our long term partners, National Trust, to take part in 2 coastal BioBlitzes. These coastal BioBlitzes are part of a nationwide event of 25 coastal National Trust sites around England, Wales and Northern Ireland to celebrate 50 years of Project Neptune.

The first will be in Whitepark Bay on Saturday 20th June and the second in Murlough NNR, Co. Down on Saturday 4th July.

The focus of these two events will be very much on encouraging new recorders so anyone who would be interested in demonstrating recording or leading a recording party during the event please get in touch with us at

We’d love to see you all there to help celebrate these two important anniversaries.

And, if you are wondering about Ireland’s BioBlitz… Liam and his team are taking a well-earned break this year but will no doubt be back with something new and exciting next year.

Crawfordsburn Country Park

The moth traps were disappointing on the Friday night (too cold and windy) but on Saturday there was a brilliant turnout and the sun came out. It was great to see so many enthusiastic recorders pulling in pages of species records.Thanks to the collective input of a number of expert recorders and very interested and enthusiastic members of the public we won the competition recording a staggering 984 species in the park over 24 hours continue reading...
