The Prince has planted a sapling grown from an ancient oak on his estate
Prince Charles has joined birthday celebrations to mark Gloucestershire's millennium by planting a sapling grown from an ancient oak on his estate.
One thousand trees are being planted across the county to mark its millennium year.
The "1000 Trees" campaign invited local people and businesses to plant or sponsor a tree.
The University of Gloucestershire has planted more than 150 trees in their aim to be a sustainable university.
Laura Fleming from the 1000 Trees project said: ""We are absolutely delighted that His Royal Highness has so kindly agreed to join the celebrations by planting a tree in his gardens."
"His support gives added weight to the campaign and the social and environmental challenges facing us in Gloucestershire over the next 1000 years."
