Britain's heatwaves have exposed a stark reality: the country's most disadvantaged children are missing out on a vital lifeline – the shade provided by trees in their school grounds. New research reveals that private schools boast 41% more tree cover than state schools, leaving many youngsters to endure sweltering temperatures in classrooms.
The study, conducted by environmental social scientist Lewis Winks, mapped every primary and secondary school in England, cross-referencing the data with government records on woodland and individual trees. The result: among state mainstream schools, those serving areas with high free school meal eligibility – a key indicator of poverty – have 29% less tree cover than their wealthier counterparts.
The median tree cover for these disadvantaged schools stands at just 11.7%, compared to 16.3% in more affluent localities. This chasm has significant implications, especially during periods of extreme heat when temperatures can soar up to 40C. Trees play a vital role in mitigating the effects by providing shade and through transpiration – a process that can lower surface temperatures by as much as 12C to 18C compared to unshaded asphalt or concrete.
Teachers have had to resort to makeshift solutions, such as wet paper towels and trays of water, to combat the heat. Lewis Winks lamented: “It's unacceptable that these benefits are so unevenly distributed, with the most advantaged children more likely to attend schools with greener, better-shaded surroundings.” He highlighted the multiple advantages trees provide – improved well-being, air quality, biodiversity, and enriched outdoor learning opportunities.
The disparities in tree cover extend beyond urban and rural divides. Areas like Blackpool (4.9%), Bradford (6.1%), and Luton (7.7%) have some of the lowest levels of tree cover around schools, while affluent areas like Wokingham, Richmond upon Thames (20%), and Hampshire boast significantly more trees near school buildings.
