Thousands of trees could be under threat in Edinburgh where a new species of Dutch elm beetle has been discovered.

Last year’s hot summer is believed to have encouraged the beetle which, along with its larger relative, was responsible for the felling of more than 1,300 trees in the city last year.

The exercise, which included felling and replacement, cost Edinburgh city council £40,000.

Edinburgh has around 18,500 elms unaffected by the beetle, and they will be closely monitored to help prevent spread of disease.
