The Archbishop of Canterbury has planted a fig tree at Lambeth Palace.
Most Rev Justin Welby is part of the Queen's Green Canopy, a tree-planting initiative that invites people from across the United Kingdom to "plant a tree for the Jubilee" during the official planting season between October to March.
Tree planting will commence again in October 2022, through to the end of the Jubilee year.
Lead bishop for the Church of England on environmental issues, Rt Rev Graham Usher and the CEO of The Queen's Green Canopy Colonel Dan Rex also took part in the event in Lambeth Palace.
The Archbishop of Canterbury said: "It's a fitting tribute to Her Majesty The Queen's seven decades of service, and the trees we plant this year will be a sign of our gratitude and celebration of this remarkable occasion for many decades to come."
Bishop Graham Usher also said: "Planting a tree is always about expressing hope in the future and is a gift to the rest of creation, as well as future generations.
"Over seven decades, Her Majesty The Queen has planted more than 1,500 trees and it is fitting that Her Majesty The Queen, has chosen to mark her Platinum Jubilee by encouraging us to join up this tree canopy."
The Queen's Green Canopy will also dedicate a network of 70 Ancient Woodlands across the United Kingdom and identify 70 Ancient Trees to celebrate Her Majesty's 70 years of service.
