City Nature Challenge at Gunpowder Falls State Park - Sweet Air Area

Join DNR experts and educators at the Sweet Air Area of Gunpowder Falls State Park to participate in the 2025 City Nature Challenge!

Stop by to take part in this open house style bioblitz anytime between 9 AM and 12 PM!

Started in 2016 as a competition between Los Angeles and San Francisco, the City Nature Challenge has grown into an international event, motivating people around the world to find and document wildlife in their own cities!

Taking Part is Easy:

• Find Wildlife: It can be any WILD plant, animal, fungi, slime mold, or any other evidence of life found in your city.
• Take a Picture/Record a Sound: Take a picture or record sound of what you find. Be sure to note the location of the critter or plant.
• Share: Share your observations through iNaturalist or your city's chosen platform. If it's planted or taken care of by people it is not WILD. Mark it captive/ cultivated!

By participating in the City Nature Challenge, not only do you learn more about your local species, but you can also make your city a better place – for you and wildlife!
