Cities around the world collaborate to share observations of nature in the 2025 City Nature Challenge.
Started in 2016 as a competition between Los Angeles and San Francisco, the City Nature Challenge has grown into an international event. The City Nature Challenge is an annual four-day global bioblitz at the end of April, where cities are in a collaboration-meets-friendly-competition to see what can be accomplished when we all work toward a common goal.
The 2025 City Nature Challenge takes place in 2 parts:
- 25 April – 28 April: Taking pictures of wild plants and animals
- 29 April – 4 May: Identifying everything found
Results will be announced on Monday May 5, 2025.
In Aotearoa there are three cities involved with the challenge: Tāmaki Makaurau Auckland, Pōneke Wellington and Ōtautahi Christchurch.
