Staff at an Oxford law firm are to plant hundreds of trees to mark a special anniversary.

Marshall and Galpin, based in New Inn Hall Street, is planting 225 trees at a site near the A34 at Kennington tomorrow to commemorate its 225 years in business.

Senior partner Stephen Woods said: "We wanted to leave a lasting reminder of the firm and provide a 'green lung' close to busy roads. We have deliberately picked a selection of native British tree species."

The trees - oak, ash, field maple, small-leafed lime, hornbeam, birch, alder, and sweet chestnut - will be planted by volunteers from the firm.
