Sir I was horrified to see in the winning architect's plans for Bonn Square published in your paper, March 10, that at least two more beautiful mature old trees will disappear. Trees of this size take over 100 years to grow and provide essential natural beauty in a townscape bereft of it. They should not be destroyed, but could be made into a feature with an area of grass and flowers around them. Those trees, if allowed to stay, as well as combating carbon dioxide emissions, could help to improve that area of the centre of Oxford far more than the concrete jungle of poles and paving stones provided by this new plan, and would be cheaper to implement.
