The Home River Bioblitz 2020

The Home River Bioblitz 2020


The Home River Bioblitz is a worldwide collaboration between citizens to show the importance of free-flowing rivers. It is a communal citizen-science effort to connect people to their local river environments and non-human inhabitants, zooming in to details they normally pass by while generating useful data for science and conservation.

This year’s bioblitz occurred on the 20th of September and over 500 people around the world logged +5245 observations // +1772 species in over +40 locations – across 5 continents!
