The Woodland Trust has launched a new 'zero-carbon' pedestrian and cycle trail, which is designed to increase public access to some of London's ancient trees.

A 500-year-old holm oak at Fulham Palace and Barney - a London Plane in Barnes - have been included as part of the trail, which starts in the centre of the capital. The route follows Sustrans National Cycle Network Route Four along the Thames and into Richmond Park, before ending at the Royal Botanic Gardens in Kew.

London mayor Boris Johnson said: "The London tree trail is a great way to while away an afternoon, cycling and spotting London's majestic, ancient trees."
