Hit up the launch of Positive Trace Parties ‘Rumble on the Roding’ with tree-planting party on the banks of London’s ancient River Roding. Get your hands dirty and help clean up the river, which has become blocked with rubbish, plant ecologically specified trees, build floating wildlife rafts to welcome to kingfishers, otters and swans. Your hard work will be rewarded with a banquet, drinks, live music and DJs. All profits will be donated to the River Roding Trust and Ecosystem Restoration Camps, so that they can carry on their work of restoring degraded ecosystems in London and beyond.
