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.

Join us for Broomfield's First-Ever iNaturalist BioBlitz!

A bioblitz is a communal citizen-science effort to record as many species within a designated location and time period as possible. Broomfield's BioBlitz will be held at Quail Creek and Plaster Reservoir all day on Friday June 15 and Saturday June 16. Experienced naturalists and equipment to borrow will be made available to assist in app navigation and species identification on Friday 4-6 p.m. and Saturday 7-9 a.m. Learn about Broomfield's flora and fauna while trying to identify as many species as possible in this friendly competition! 

This event is free to attend and no registration is needed. All ages are welcome, with adult supervision required. Please park at the Quail Creek Park lot (2202 W 138th Ave). 

Join the hunt for Broomfield's wildlife species by posting observations to Broomfield BioBlitz 2018 with your iNaturalist account.
