Cardiff’s urban forest grows by another 36,000 trees

7.5.25

An urban forest project developed by Cardiff Council as part of its ‘One Planet Cardiff' response to climate change has planted 36,526 new trees in the last 7 months.

This season's planting, which included 280 new semi-mature trees on Cardiff's streets and another 1,144 semi-mature trees in green spaces around the city, means that over 118,500 trees have been planted since the Coed Caerdydd (Cardiff Forest) project began in late 2021.

Oak, Rowan, Hawthorn, Alder, Beech and other native species were some of the most planted trees this year, but the project also saw the reintroduction of rare ‘Gabalva' apple trees to the city for the first time in around 100 years.

Cabinet Member for Culture, Parks and Events, Cllr Jennifer Burke said: "Over time, these new trees will make a real contribution to our net-zero carbon ambitions, as well improving the quality of the air we all breathe, providing important habitats for wildlife, soaking up water in wet conditions, and providing welcome shade during hot weather.

"The community response to the project has been fantastic. Thanks to the help of residents, local community groups, schools and businesses, trees planted as part of the project now cover an area the size of almost 30 Principality Stadium pitches. That wouldn't have been possible without the 16,000 hours of time they have donated to making Cardiff a greener city."

Coed Caerdydd Project Manager, Chloe Thorn, said: "This year we had more than 2,100 volunteers working with us at 114 community planting sessions all over the city and another 800 volunteers helping out at the tree nursery where we look after all our trees until they're planted. It's been amazing, but even now the planting season has ended there are still loads of opportunities for volunteers to get involved.

"Looking after the newly-planted trees is really important - which is where the 300 volunteer tree guardians, who help us monitor the health of the new trees and provide additional water where possible, are so great. We're always looking for more volunteers - the more help we have, the quicker Cardiff's forest will grow."

All street trees planted in hard surfaces are planted in tree pits which contain root barriers specially designed to force roots downwards, minimising the risk of potential damage to pavements and nearby properties.
