Engage With Us! Record your outdoor observations, share with fellow naturalists, and discuss your findings in Broomfield. 

What is iNaturalist?

iNaturalist is a website where people can report their observations of all types of organisms, from animals to fungi! Broomfield Open Space and Trails has created a project on iNaturalist for everyone to submit observations, findings and questions from across the county. It doesn’t have to be on open space, it could even be something you saw in your backyard! You can use iNaturalist to get help with species identification and to record where you observed something. The site works on a “crowdsourced identification system” where you can upload an image or a sound clip of the organism you observed and other users of the website help you identify it. An image or sound clip is encouraged but not required to submit observations.
