Residents rallied together to plant 500 trees and create a ‘Cranbrook Canopy’.
Some 40 volunteers of all ages took part in the community event at the town’s Country Park in the heart of the Clyst Valley.
New native woodland includes 250 oak trees.
Cranbrook Canopy is a five-month project funded by the Woodland Trust’s Street Trees project, supported by the People’s Postcode Lottery, East Devon District Council (EDDC) and Cranbrook Town Council.
It aims to inspire the people of Cranbrook to engage with trees and the landscape around them.
Organisers hope the scheme can leave a lasting legacy of improved green spaces and more tree canopy for a healthier future for the new town.
Cllr Les Bayliss, chairman of Cranbrook Town Council, added: “The tree planting was a wonderful community activity and I’m delighted so many local adults and children helped to make Cranbrook a greener place to live and work.
“Increasing the number of native trees within the Country Park will enhance the wellbeing of residents, provide a home for animals and birds, and help to reduce our carbon footprint.”
Councillor Kim Bloxham, EDDC ward member for the town, thanked the volunteers and said: “The trees will not only improve the overall enjoyment of the park by making it more attractive, but also help combat climate change and increase wildlife and diversity.
“Most importantly, the Cranbrook Canopy project will encourage local people to help make Cranbrook an even better place to live.”
Some 50 fruit trees will be given away at a wildlife gardening fair in the town on Saturday, March 14.
The tree planting event took place on Saturday, February 8.
