City Nature Challenge BioBlitz

April 24, 2020 - April 27, 2020

In celebration of the 50th anniversary of Earth Day, organizations across the Upper Willamette watershed invite you to join your community in documenting our local nature during the 2020 City Nature Challenge! 

As we stay home and stay safe to stop the spread of COVID-19, we can still observe and document the natural world in our backyards, on our sidewalks, and even in our homes!

The City Nature Challenge (CNC) is a community science bioblitz with the goal of observing and identifying as many species as possible in urban communities. Participants from more than 200 cities worldwide will contribute and so can you! 

You may be wondering – what is a BioBlitz? ‘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 as possible, within a set location, over a defined time period. Plants, animals, fungi, it all counts! Even tracks and other evidence of a species can be recorded. 

Find out the name of that mystery plant growing nearby with iNaturalist, a free and easy to use app and website with a community of experts helping you identify what you found. If you are in the Eugene-Springfield CNC area and you make an observation on iNaturalist from April 24th-27th, it will automatically contribute to our total. How many species can we find?

Please follow all travel and social distancing guidelines as we bring technology and nature together to celebrate the 50th anniversary of Earth Day. Discover the nature around you during the City Nature Challenge!
