City Nature Challenge is an annual four-day global ‘bioblitz’ nature hunt, to assist in recording and protecting wildlife in urban areas. Every year, cities all over the world take part in friendly and fun competition to see who can gather the most observations of nature and find the most species.

A global event

In City Nature Challenge 2023, over 1.8 million observations were made of over 57,000 species with over 66,000 people taking part across the world – an astonishing collective effort that we can eclipse in 2024 with your support.

For 2024, individuals, families, and community groups in over 400 cities globally are invited to look for nature in their gardens, parks, public spaces or homes and join this worldwide effort to record as much wildlife as possible between 26 – 29 April 2024.

It’s simple, fun and anyone can join in

All you need is a smartphone and the iNaturalist mobile app. Share a photo with the app and it will assist you to identify and record the species you find. Each species record is known as an observation, and all observations made during the event in participating areas will count towards City Nature Challenge.

You can then join  other nature enthusiasts to work together to formally identify the records before they are shared for inclusion in local and national wildlife databases, which support nature conservation efforts.
