What is the City Nature Challenge?
The City Nature Challenge is a collaborative international bioblitz that started in 2016 as a competition between Los Angeles and San Francisco. The objective for the challenge is to motivate people in their surrounding area to get outside and document wildlife and general biodiversity. In 2017, the City Nature Challenge went
national, and one year later, became a world-wide event.

City Nature Challenge and Citizen Science
The City Nature Challenge is an excellent opportunity for community stakeholders to learn about nature surrounding them, and through documentation with iNaturalist, can even assist in studies to protect local biodiversity. The City Nature Challenge also works to promote environmental education, and is being adapted by school educators for lessons and activities on biodiversity and nature immersion.
