Join the City Nature Challenge April 25-28 when thousands of people from 600 communities across the globe will be community scientists by getting outside, looking for nature, and logging their findings in iNaturalist.org. Let's see what can be accomplished when we all work toward a common goal!

You can help Denver by participating in this challenge alongside Denver Parks and Recreation and Highline Canal Conservancy staff on April 26 at James A. Bible Park.

DPR and the High Line Canal Conservancy will be hosting this event from 11:00 a.m. - 1:00 p.m. The event is open to all ages and only requires a smartphone, tablet (or iPad), or camera. No prior identification knowledge is needed!
