City Nature Challenge


Which city on Earth has the most wildlife and the most nature-loving citizens?

Between 26-29 April 2019, Bristol and Bath will unite to compete with 185+ cities on seven continents as we show the world how amazing our region is for people and nature during the 2019 City Nature Challenge. Defending our 2018 title of most observations in Europe, together we will embark on an epic contest: to discover and record as much wildlife as possible over 4 days.

Simply download the free iNaturalist app and start uploading photos of all the wild plants, animals and fungi you find to help Bristol & Bath climb the international rankings.
