City Nature Challenge: Manor Woods Valley Bioblitz

Manor Woods Valley, Bristol, BS13 7LN
Sunday 26th April 2026
BS13 is host to our next bioblitz as we return to Manor Woods Valley for a City Nature Challenge special!

The idea behind Citizen Science Sundays is simple - Bristol is home to so many hotspots for nature, so we want to join forces with other like-minded locals and help to map the biodiversity found in our city, whilst taking time to appreciate the nature on our doorstep. Bristol also has a network of dedicated postcode-specific wildlife groups, each with its own iNaturalist project. Visiting a different postcode each time, we’ll be heading to a green space within that postcode and spending a few hours combing the area whilst taking note of what’s growing, flying and thriving there.

Recording our finds using cameras, phones and the iNaturalist app, we’ll be contributing useful data which is available to scientists and conservationists worldwide, helping them to build pictures of biodiversity at all levels. We’ll also be taking notes of the birds we spot, before submitting our records to the Bristol Regional Environmental Records Centre. 

Everyone is encouraged to join in regardless of level, from enthusiastic beginners to seasoned bird nerds. If you see something interesting but aren’t sure what it is, you can ask your fellow observers, or just snap a photo – we can always identify it later.

Our next postcode of 2026 is BS13, where we’ll be exploring Manor Woods Valley, returning to the site we last visited 3 years ago as part of City Nature Challenge! CNC is a global event that pits cities against each other in a friendly competition, seeing who can find and make the most observations of nature. For more information (and to see results from previous years) head here.

We’ll be meeting at the southern entrance to the site off St Peters Rise, near Bishopsworth Library (What ThreeWords///swaps.jumps.sake) for a 10am start, finishing by 1pm. The Firstbus-operated 37,43, 75 and 76 stop on nearby Church Road. Be sure to bring suitable clothing and footwear, as well as something to keep hydrated. 

These events are free to attend, but there’s also an option to donate. All donations go directly to the RSPB Bristol Local Group, helping us to put on future events. To learn more about Citizen Science Sundays, iNaturalist and the Postcode Wildlife Groups, you can click here and see our guide.
