City Nature Challenge 2025 - Cardiff & Newport


Join Cardiff & Newport in Celebrating the 10th Anniversary of the City Nature Challenge!

What started in 2016 as a friendly competition between Los Angeles and San Francisco has now grown into a global celebration of nature. The City Nature Challenge has become an international event, inspiring people across the world to explore and record wildlife in their own cities.

Be Part of a Global Wildlife Mission

This year, join residents from over 700 cities across all seven continents for an exciting mission to document wildlife! For four days, we’re asking you to record as many nature observations as you can using the free iNaturalist app, helping to contribute to wildlife records in not only Cardiff and Newport but across the globe.

View the City Nature Challenge map to find out which cities are participating!

Why Should You Take Part?

We can only protect the wildlife we know is there! By participating in the City Nature Challenge, you’ll gain a deeper understanding of the wildlife around you and your observations could help protect local nature and support conservation efforts both locally and globally.

How Can You Take Part?

Getting involved is simple! Just download the free iNaturalist app to your smartphone or tablet, and start uploading photos of the wildlife you encounter. You don’t need to be a wildlife expert – iNaturalist will assist you to identify and record the species you find. Plus, a community of scientists and nature enthusiasts will help verify your sightings.

25-28th April - Observe and record local nature

29th April - 5th May - Help verify what was found

You can take part in the challenge by recording observations in your own garden, local greenspace or by joining an organised event near you - more details to follow!
