Biodiversity Challenge - Wageningen University & Research

Will you join us outdoors to see, feel and taste nature on the Wageningen Campus? Once again this year, we will venture outside to admire the extraordinary biodiversity around us. Register for one of our guided excursions, or grab your phone and go discover species with colleagues, friends or just by yourself.

As in 2023, Wageningen University & Research will once again compete against 18 other life sciences universities from the European ICA network. Who will find the most, most beautiful and most unusual wild species on campus?

Bioblitz: record species with an app

How exactly does the Bioblitz work?

Recording species is very easy. To do so, you can download one of three apps from the App Store or Play Store: ObsIdentify (for Android and iOS), ObsMapp (Android only) and iObs (iOS only). With those apps, you take a picture of what you see, and then read on your screen which species it probably is. Then you submit your sighting at the touch of a button. You can also enter sightings directly on

Please note that we only count wild species! Planted flowerbeds or animals kept by humans will be rejected.

How do I add my entry to the Biodiversity Challenge?

Your entry will automatically be added to the Biodiversity Challenge when submitted between 2 May and 28 June at a location belonging to Wageningen University & Research. This applies both to the Wageningen Campus and to WUR locations outside Wageningen.

What happens to the collected data?

The data collected from the Biodiversity Challenge will be used to monitor the score, and see how great our biodiversity is compared to other universities in Europe. Afterwards, students will work with the data to map the distinctive observations, and compare them with data from previous years.
