Join us in a fun, nationwide challenge to see which city can document the most species during April 14-18. It is easy to participate by joining an event, or making observations on your own using the iNaturalist app. With the iNaturalist app, you just take a picture of a plant or animal, and the community will help identify which species it is. All iNaturalist observations from the greater metropolitan area of D.C. (as defined by the census) made during the five day challenge will count towards our total.
