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. Any observation in the greater metropolitan area during the five day challenge will count toward the Washington DC Metro area totals. But while you're in Four Mile Run park, add your observations to our Four Mile Run Conservatory Project as well.
The City Nature Challenge 2017 is just in time for National Citizen Science Day (April 15) and Earth Day (April 22), 16 U.S. cities are asking residents of and visitors to these urban areas to explore nature all around them and document the species they find.
iNaturalist is a place where you can record what you see in nature, meet other nature lovers, and learn about the natural world. Help the Four Mile Run Conservatory explore our neighborhood park and at the same time join folks from around the country in the great experiment in citizen science!
