To elevate urban forestry in Wales, Ysgol Plas Coch in Wrexham has become a beacon for environmental action. Partnering with the Woodland Trust (Coed Cadw) and Wrexham Council, the Welsh-medium primary school has used the Emergency Tree Fund to transform its grounds into a “living classroom” designed to combat air pollution and promote social equality through nature. This initiative is more than just a typical school gardening project; it is a data-driven response to Tree Equity—a burgeoning movement within the woodland industry that ensures the life-saving benefits of trees are distributed fairly across all urban neighbourhoods, regardless of socio-economic standing.
The project was sparked by the Woodland Trust’s Tree Equity Score UK tool. This sophisticated mapping technology analyses canopy cover alongside data on air quality, population density, income, and surface temperature. For Ysgol Plas Coch, the data revealed a clear “canopy gap.”
Located near busy transit corridors, the school was identified as a high-priority site where additional tree cover could serve as a vital bio-filter. Research shows that urban trees can reduce particulate matter (PM2.5) by up to 60% in localised areas, while dense leaf structures—such as those found in the native species planted at the school—can scatter and absorb noise waves, creating a quieter, more focused learning environment for pupils.
The planting day saw pupils trade textbooks for spades, getting hands-on with the soil to plant three distinct types of green infrastructure:
A native fruit orchard: Designed to provide fresh produce and teach children about sustainable food systems.
A mixed native hedge: Specifically selected for its ability to trap roadside pollutants and provide a “wildlife corridor” for local pollinators.
Standard trees: Large-canopy species that will provide critical shade and carbon sequestration as they mature.
In a move that bridges conservation with the STEM curriculum, the school also installed high-tech air quality sensors. These devices allow students to monitor real-time data, providing empirical evidence of how their new “green wall” improves the air they breathe.
“The pupils have learnt new skills that they will be able to use as they develop to be responsible citizens,” says Osian Jones, Headmaster at Ysgol Plas Coch. “As well as increasing the tree coverage to improve air quality, it gave the pupils hands-on experience as part of our ‘On Our Doorstep’ curriculum theme.”
The Emergency Tree Fund, which supported the Wrexham project, is a multi-million-pound initiative by the Woodland Trust designed to help local authorities break through the financial and logistical barriers of urban planting.
Jacinta Challinor, Tree Equity Lead for the Woodland Trust, emphasises that the mission is about health as much as it is about habitat. “Tree equity is about ensuring that everyone, no matter where they live, has access to shade and clean air. Ysgol Plas Coch is leading the way in tackling environmental challenges at a local level.”
As the UK’s largest woodland conservation charity, the Woodland Trust (Coed Cadw in Wales) continues to drive three core pillars of the woodland industry:
With over 500,000 supporters and 1,000 sites across 33,000 hectares, the Trust’s work in Wrexham is a microcosm of their national goal: to create a world where trees and people thrive together.
