A bold environmental project is planning to reconnect London’s overlooked green spaces, creating a greener, cooler and more wildlife-friendly capital. The London Tree Ring could benefit up to 10 million people while offering a practical model for urban nature recovery.
Positive news ireland and beyond: London unveils a green vision
Led by CPRE London, the London Tree Ring is designed as a 200-kilometre corridor of trees, woodland, hedgerows and connected habitats around the capital’s outer boroughs. Organisers describe it as an “M25 for nature” because it would form a continuous green edge around London.
The 25-year project aims to protect greenbelt land, restore neglected natural areas and improve conditions for species that have declined. It also reflects a growing understanding that urban greenery can support climate resilience, public health and stronger local communities.
Why the project matters
London’s green spaces face pressure from development, drought, extreme heat and habitat loss. By linking isolated pockets of nature, the scheme could help wildlife move between habitats while giving residents more access to trees and open spaces.
- Natural shade and cooler neighbourhoods during hot weather
- Improved habitat for birds, insects and native plants
- Greater protection for sections of London’s greenbelt
- Opportunities for community volunteering and environmental skills
- More resilient landscapes during drought and climate pressure
Community groups are central to the plan
The London Tree Ring is not simply a tree-planting programme. Over the next quarter-century, schools, community organisations, landowners and skills providers are expected to help identify planting locations, care for young trees and manage restored habitats.
Early projects show how local involvement can produce practical results. On London’s south-western boundary, a countryside skills provider helped plant 1,500 trees to restore hedgerows, including disease-resistant elm. Elm was devastated by Dutch elm disease in the 1960s and 1970s, while its loss also affected the white-letter hairstreak butterfly, whose caterpillars depend on elm leaves.
In Sutton, CPRE London worked with council tree wardens and pupils from Glenthorne High School to create a Miyawaki-style microforest at Reigate Avenue recreation ground. The method uses densely planted native trees and enriched soil to encourage rapid establishment. The site has performed well despite dry conditions and limited irrigation.

A blueprint for cities beyond London
CPRE London is working with organisations including the Forestry Commission, Woodland Trust and Trees for Cities. The project’s organisers hope the lessons learned can support similar green corridors in towns, cities and greenbelt areas across the UK.
Ten demonstration sites were planted during the 2025/26 season, providing early examples of how residents and local institutions can collaborate on nature recovery. The official launch is scheduled for 15 October, with online participation available through CPRE London.

The wider lesson from London’s tree ring
The project demonstrates that nature restoration can be designed around people as well as wildlife. Residents who plant and care for trees can see the results develop over decades, while neighbourhoods gain shade, healthier habitats and shared public spaces.
It also shows why connected habitats matter. Individual parks and woodland patches are valuable, but linking them can create a stronger ecological network and improve the chances of species recovery.
Conclusion
The London Tree Ring is an ambitious example of positive news Ireland audiences can follow as part of the wider global movement for practical climate action. With long-term planning, local participation and careful habitat restoration, a greener edge around London could improve daily life for millions and inspire similar projects elsewhere. This is the kind of positive news digest story that shows meaningful change can begin with communities planting and protecting trees together.
