Nature enthusiasts are getting together in a big way this weekend to take a walk. More specifically, a BioBlitz nature walk.

The Bioblitz walk across the Americas is January 16-17. It’s a pretty simple premise: Take a walk with your friends and family and share your findings with the world using the iNaturalist app on your smart phone. It’s the perfect excuse to let technology help us pay attention to nature. 

Although this weekend’s event can take place anywhere—from  your backyard to your local park—there are a couple of biomimicry network groups hosting Bioblitzes.

In the Arizona area? Try this Bioblitz in the Sonoran Desert. In the California area? The Coastal Redwoods Biomimicry Group is also hosting an event. Both events are free.
