West of England (previously 'Bristol & Bath')

City Nature Challenge will be running across the Bristol & Bath region again this year, under the new project name ‘City Nature Challenge 2023: West of England’. Help gather as many wildlife records as possible and help put nature on the map from Friday 28th April – Monday 1st May.

Local charity The Natural History Consortium is leading activity for the West of England during the challenge, hosting iNaturalist training and wildlife recording hubs across Bristol and Bath over the four-day event.

In last year’s challenge, the West of England reached a whopping 8,006 nature observations, 1,264 species recorded, and 406 individuals taking part – putting us top of the leaderboard for participants and second place for observations and species numbers. Let’s beat this in 2023!


Local activity hubs

There will be City Nature Challenge activity hubs popping up in green spaces across Bristol, Bath and North East Somerset, North Somerset, and South Gloucestershire to help residents learn how to use iNaturalist and join engaging guided nature walks and workshops to practice new wildlife recording skills.

Tackling the Ecological Emergency

Across the West of England, wildlife and biodiversity is struggling. We are in a state of ‘ecological emergency’, meaning nature is declining all around us and urgent action needs to be taken to help it. For us to support nature’s recovery, it’s important to know what wildlife exists, where it is located, and what is missing from the map. City Nature Challenge is a chance for anyone and everyone to play a part in tackling the Ecological Emergency in the region by taking photos of the wildlife they see and uploading it on the iNaturalist app.

Become a Citizen Scientist for the region

Your wildlife recordings submitted on the iNaturalist app during the challenge will be used by the Bristol Regional Environmental Records Centre (BRERC) for conservation purposes and go towards important monitoring for our Ecological Emergency.

Bees and Trees

During this year’s challenge, the West of England region will be highlighting the importance of pollinators and trees. Pollinators include: bumblebees, honey bees, solitary bees, wasps, butterflies, moths, beetles, hoverflies. Trees to record might include: hazel, english oak, elder, hawthorn, horse chestnut, silver birch. The Natural History Consortium will be leading a programme of activities across Bristol and Bath to help people find and record pollinators on iNaturalist. The West of England Combined Authority is funding this activity.*

How do I take part?

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 over Friday 28th April – Monday 1st May.

After you upload your photos, the app will give you some handy suggestions of what it thinks you’ve seen. An online community of scientists and wildlife enthusiasts will then verify your sighting. It’s a great way to learn more about the wildlife around you, and best of all, the records you submit can help inform local and national conservation work.

Check out our guide to using iNaturalist to get started and learn some top tips for recording different species. No need to wait until the challenge though – you can start using the app today!

Join the Project Page

Once you’re on the app, join the iNaturalist ‘City Nature Challenge 2023: West of England’ project page to see live updates on how your local area is doing during the challenge e.g. number of observations, species and participants.

You can also join the UK City Nature Challenge Leaderboard to see live results from all the cities taking part and watch the wildlife recording race as it happens!
