UKBMS Transect Surveyor (Ringstead Downs, Hunstanton, Norfolk) in London

Our Transect Walkers help us to understand butterflies in their local area and, by extension, across the UK. They inspire people to better understand the butterflies that they see.

Transect recording is an important aspect for monitoring the status of our butterflies. Its value lies in the fact that butterflies are recorded over a specific route over many years. In this way, we produce scientifically important data which can be used in official statistics.

We are looking for volunteers to continue data collection for the 2026 recording season that starts on the 1st April at Ringstead Downs near Hunstanton, Norfolk. The site has a long history of butterfly monitoring. Transect walks involve a walk once a week (ideally) over a prescribed route to record sightings.

Ringstead Downs is one of the largest remaining areas of chalk grassland in Norfolk; the nature reserve is managed by Norfolk Wildlife Trust. The butterfly transect was established in 2010 to monitor the butterflies of the site, and several species occur there including Green Hairstreak and Brown Argus.

You can find out more about what is involved in undertaking a butterfly transect by visiting the UK Butterfly Monitoring Scheme (UKBMS) website.

To find out more about this opportunity please contact the Transect Coordinator for Norfolk, David Cooling via david.cooling@butterfly-conservation.goassemble.com.

At Butterfly Conservation, we want to create a world where butterflies and moths are enjoyed by everyone, forever. We need people to walk transects to collect data. This data is used to inform decisions which help to conserve butterflies, both locally and nationally.

You will be volunteering with a wide range of people helping us to monitor butterflies in your local environment.

Surveying a transect involves recording butterflies and day‐flying moths along a set route every week between April and September. The route can be shared with other volunteers to reduce the time commitment from each person. We ask that you commit to a minimum of 6 months in this role and complete training when you start. Children aged 13-15 must be accompanied by an adult whilst volunteering. If you are aged 16 or 17, your parent may give written permission for you to volunteer unaccompanied.
