The Friends of The Trap Grounds


Welcome on behalf of the Glow Worms and Water Voles of the Trap Grounds. Here you can discover what makes this patch of wilderness in suburban north Oxford so special, and why we campaigned all the way to the House of Lords to register it as a Town Green.

Click on the relevant pages to find a full list of the threatened and protected species that live on the site … the texts of the legal verdicts in the Public Inquiry, the High Court, the Court of Appeal, and the House of Lords … and details of how you can join The Friends Of The Trap Grounds and help to preserve six acres of reed bed and scrub land for conservation, recreation, and education.

The site lies between the canal and the railway line, immediately south of the Frenchay Road canal bridge (off Woodstock Road) at grid ref. SP 503081 (see map). An information board marks the entrance to the site, at the start of a track called Frog Lane. Click here for a map of the habitats and other features.
