Newly-appointed tree tsar Henry Tang Ying-yen said yesterday he did not see any need to introduce any new laws despite calls by experts for a new tree ordinance. The chief secretary, who heads a taskforce set up to overhaul the city's tree management after a student was killed by a falling trunk in Stanley, said Coroner's Court recommendations - including establishment of a dedicated tree office and recruitment of local and overseas experts for risk assessment - would be studied. But he said existing laws empowered government departments to remove trees when they posed a danger to pedestrians and there were principles for preserving old trees. 'For trees on private sites, I believe the owners will also properly protect them and I do not feel the need for [further] legislation,' he said after a visit to Victoria Park to inspect tree management there. Chief Executive Donald Tsang Yam-kuen assigned Mr Tang to head the taskforce at the end of last month, a day after an inquest jury found that the death of 19-year-old Kitty Chong Chung-yin in Stanley in August last year could have been prevented with better tree management. The jury said the Leisure and Cultural Service Department, from management to frontline workers, lacked professional knowledge about trees while there were some eight departments handling tree-related issues. Mr Tang said the taskforce would study the co-ordination of different departments but insisted the existing mechanism to determine whether a tree should be felled was effective. 'We have not yet reached a conclusion on whether or not to set up a department to co-ordinate all tree- related issues. We are hoping that with the specialists group we can make more accurate judgments on tree handling,' he said, referring to the local and overseas experts. The taskforce will conduct a three-month review and is due to report by late June. Mr Tang added that tree inspections would be speeded up so that trees at risk could be identified before the typhoon season this year. In response, tree experts called for a more long-term solution. 'The secretary's remarks are just a standard line to take,' Jim Chi-yung of the University of Hong Kong said. 'We need a set of laws to protect the city's trees, especially those on private sites.' Professor Jim said private land owners had been cutting down trees with conservation value due to loopholes in the existing system - under which the land leases of some private sites did not require owners to properly maintain and preserve old trees. 'Instead of setting up a trees office, allowing a department to specialise in tree conservation would be an easier and more effective way out,' he said, adding it would be difficult for an office to co-ordinate the work of 10 departments and several bureaus. Apart from frontline workers, Professor Jim said managers and officers of professional grades of various government departments also needed more professional training, because 'they are the one who make decisions on tree cutting'. Conservancy Association conservation manager So Kwok-yin said he expected more comprehensive measures from Mr Tang. 'The coroner's suggestions are just recommendations to improve the basic works, like day-to-day assessment,' he said. 'The city needs more macro measures.' He said it would be difficult to preserve trees on private sites without new regulations. A motorcyclist was injured last night when a 3-metre tree branch fell onto a road in Mid-Levels. The 46-year-old Pizza Hut delivery rider suffered elbow and shoulder injuries after riding over the branch and losing control of the machine. He was treated at Queen Mary Hospital. The accident happened on Robinson Road, near Ying Wa Girls' School, at 9pm. A section of a westbound lane was closed last night. The branch came off a tree on a privately-owned slope 12 metres above the ground.
