The nature reserve at Porton Down is one of the largest uninterrupted tracts of semi-natural chalk grassland in the UK. During our visit we will help monitor the Duke of Burgundy colony by doing some timed counts. You don't have to be an expert, but basic identification skills are required.

The trip is limited to 20 people and places must be booked by Friday 26th April. You must be a member of Butterfly Conservation to participate. Please be prepared to submit personal details (full names, including titles, nationality, date of birth and car registration number) for the security check. Start and finish times are fixed with no latecomers admitted, and no early exits are possible.

Bring your own packed lunch and a drink. No shorts or skirts are allowed, only trousers.  Stout footwear must be worn, no sandals, flip flops or open toed shoes. People wearing unsuitable items may be denied access to the site. The reserve can bake in the summer so consider sun protection including hats and lotion. It’s also exposed so, if it’s windy, it can feel cold! Attendees should be willing to car share to ensure as few vehicles as possible are taken on site. No photography is permitted.
