The Government adopts an "integrated approach" for the management of trees. Under this approach, the different departments responsible for the maintenance of an area or a facility are also responsible for the maintenance of trees there, so as to optimise the use of resources. The duties of the TMO are to co-ordinate the tree management work of different departments, enhance public education and community involvement, provide regular training, promulgate best practices, conduct relevant researches and resolve complex cases, etc., so as to facilitate the departments to manage the trees under their care in a more effective and professional manner.
