A private company has been given a three-year contract by Oxford city council to survey 32,000 trees across the city, creating a database of those that need surgery or felling. The company, Bartlett Tree Care, has already identified 50 trees that require felling within a month. Council environmental spokesperson Caroline van Zyl claimed that tree management work would be carried out sensitively, favouring remedial work and using felling only as a last resort. Council tree experts cut down 11 diseased willow trees in Osney Isalnd last year amid fears that they would fall.
