Study warns that London’s tree stock needs to diversity to prevent serious damage from disease


A new City of London Corporation report has argued that tree diseases could seriously damage London’s green spaces unless the City’s tree stock is diversified.

‘Tree Diseases in London: The Economic, Social and Environmental Impact’ claims that more strategic planning and management of London’s tree stock is needed to increase the resilience of the green infrastructure. The report found that London’s tree stock is dominated by a small number of species with 45% represented by five species – planes, limes, maples, cherries and hornbeams. This lack of diversity means new diseases and pests could have a catastrophic effect on the overall tree population.

The City of London Corporation owns and manages almost 11,000 acres of open space, including Hampstead Heath, Epping Forest and Burnham Beeches. In February this year it hosted a conference on London’s tree health, focussing on ash dieback, massaria and oak processionary moth.
