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 175+ 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.

Your observations count towards local, national and international efforts to learn about and protect our regions' amazing wildlife. Simply download the free iNaturalist app and upload your wildlife photos, taken between 26-29 April from within the four local authority boundaries that make up the West of England.
