A ceremony to mark the end of the Queen's Green Canopy project will be held on Friday, March 31.
The tree planting project was launched in 2021 by then Prince Charles to commemorate the late Queen Elizabeth's Platinum Jubilee. He had hoped for as many trees as possible to be planted across the UK.
Residents from across Wellington and West Somerset took up the challenge. Planting at Fox's Field, the Wellington Monument and Culvercliffe in Minehead saw hundreds of new trees take root.
County-wide Somerset planted almost 40,000 trees, enough to absorb as many tonnes of C02 over a century.
Now with the project at completion, a celebration is being held in Wells Cathedral at the end of the month.
At 2pm Somerset’s Lord-Lieutenant, Mohammed Saddiq, and his predecessor, Annie Maw, will attend a blessing by Acting Dean Anne Gell of the tree planted last year on behalf of the people of Somerset in the Camery Garden of the Cathedral.
Mr Saddiq said: “This will be a fitting finale to the Queen’s Green Canopy project, which has been brilliantly supported by communities across Somerset – a lasting legacy to our late Queen.”
