About the Trap Grounds

The Trap Grounds Town Green & Local Wildlife Site in north Oxford lies immediately south of the Frenchay Road canal bridge (nearest postcode OX2 6TF). An information board on the towpath marks the entrance to three acres of reed bed and seven acres of woodland, grassland, stream, and ponds. The site (open to visitors 24/7) is owned by Oxford City Council and managed for conservation, recreation, and education by the Friends of the Trap Grounds, a group of local volunteers. For more information about current events and activities, the history and wildlife status of the site, and our campaign to save it as a Town Green, visit You can also contact the Secretary via the website.

So far this spring, Nicola Devine has photographed seven varieties of odonata on the Trap Grounds -- damselflies: the Large Red, the Blue-Tailed, the Azure, and a rare female blue form of the Azure; and dragonflies: the Hairy, the Broad-Bodied Chaser, and the Downy Emerald. Her photo of the Downy Emerald (see below) is the first-ever record on the Trap Grounds, bringing our confirmed total of odonata to 21 (out of 33 known species in Oxfordshire).
