City Nature Challenge
5th Annual City Nature Challenge
of Greater Erie!
April 24 - 27
This international community science event challenges us to explore and document the biodiversity around us. Everyone is welcome; all you need to do is download the free iNaturalist app on your phone or tablet, create an account, go outside and start exploring! iNaturalist can be used year-round to identify all sorts of plant and animal species anywhere in the world! In addition, by making observations in the app, you will be contributing to a global wildlife database that scientists can use to inform their research.
The City Nature Challenge was started in 2016 by the California Academy of Sciences and the Natural History Museum of Los Angeles County and has grown into a global event. Last year, over 650 cities from 62 countries around the world participated in the challenge with over 100,000 observers. Over 70,000 different species were documented during the 4-day event and 2025 saw the first time that more than 3,000,000 observations were made!
Any iNaturalist observations made during this 4-day period will be automatically included. Record observations from your backyard, explore the Erie Bayfront, visit a park, or come to Asbury Woods for a visit! Check out the iNaturalist website for some great tutorials on how to make an observation, how to identify an observation, and adding a photo.

Everyone is welcome! Download the free iNaturalist app from either the App or Play store on your phone or tablet, create an account, and start searching the challenge area, taking geo-tagged pictures as you go.
