Explore your local river!

A world-wide citizen science event where people explore the biodiversity of their home river.

The first Home River Bioblitz took place on September 20th, 2020. Watch the video below for a quick impression! 

More than 400 people went out to their home rivers on 46 locations worldwide.

What is a bioblitz?

A bioblitz is a communal citizen-science effort to record a wide variety of species on a specific location within a certain timeframe. Bioblitzes are a way to connect people to their environments, zooming in to details they normally pass by and at the same time generating useful data for science and conservation.

During the Home River Bioblitz, peole go out to explore their local rivers together with their peers, friends and family, thereby enlarging their local network of people that care about rivers. In the following week, it is time to identify the observed species with help of the global iNaturalist community. Afterwards, we gather online and chat about the day with various specialists, zooming into some remarkable observations as well as discussing new ways to relate to our local river wildlife.

Using iNaturalist

This Bioblitz is all about collaborating with people that value rivers and their ecosystems, both close to you as well as globally. iNaturalist is the perfect partner to share your observations with a digital community. It is an online social network of people sharing biodiversity information to help each other learn about natural systems. It functions both as a crowdsourced species identification system and an organism occurrence recording tool. And the best thing of all, it is super easy to use, making the world of biology accessible to everyone.

The next Home River Bioblitz will take place in September 2021. To get an idea of how you can join in and organise a bioblitz at your local river, have a look at the page ‘Join the bioblitz’. Note that this information was assembled for the 2020 Home River Bioblitz.
