City Nature Challenge is an epic, global citizen science project to collect information about our local wildlife. In 2022, UK cities collaborated with 450+ cities across the world to find and record as much wildlife as possible to help track how nature is bouncing back in spring!


Discover wildlife on your doorstep throughout the whole of 2022. The big international challenge weekend was held on April 29 – May 2 when all 400+ cities were active at once! Join us in spring 2023 for the next challenge.


Taking part is easy! Simply download the iNaturalist app to your smartphone or tablet and use it to upload photos of any wildlife you see from your windows, gardens and during your daily outdoor exercise.

You don’t have to be an expert, as the app will give you some handy suggestions of what it thinks you’ve seen, and you can join the iNaturalist online community to learn more about the wildlife around you. Best of all, the records you submit will help inform local and national conservation work!

Which cities are taking part?

City regions across the whole UK are taking part in the challenge next year – we’ll share the final list later in the year. In the meantime – check out the city results from 2022!

If you live in one of the signed up cities you’ll be able to see how your area is doing in comparison to other areas across the world.

However, you don’t need to be living within one of them to add wildlife records to the map. We’re excited to see the whole of the country take part in the challenge and see records from all four corners.

International City Nature Challenge

City Nature Challenge is part of a global citizen science project. Started in 2016 between just two organisations the Natural History Museum of Los Angeles County and California Academy of Sciences, and growing across the whole US in 2017, since 2018 cities from all four continents have taken part. Last year, in 2021, over 1.2 million wildlife records were submitted across the globe over four days!

In 2022, over 450 cities across the world took part – you can keep up to date with the global map by clicking here.

Choose an outside space in which to carry out a mini-beast hunt. This should take between 30-60 minutes. Look for as many mini-beasts as you can and record all the creatures you find!
