Information on 2,000 trees identified by the government as being unhealthy will be disclosed to the public following a public outcry over tree safety across the city. However, a certified arborist doubted if such a move would help reduce the risk of trees falling. Following a spate of tree collapses, including one which led to the death of a cyclist in Sha Tin, independent lawmaker Regina Ip Lau Suk-yee questioned the capability of government officers inspecting their condition. During yesterday's Legislative Council meeting she said officers had failed to spot problems with the trees in their inspections before the collapses. 'It means that the government's visual checks fail to do the gate keeping for Hongkongers. I suspect that the government officers or contracted-out workers on tree inspections do not have the sufficient expertise and experience,' she said. In one of the recent cases, the sister-in-law of the cyclist, who died on June 15, said it was ridiculous for the Leisure and Cultural Services Department to have overlooked the problem in an inspection a month before. At that time serious internal trunk decay had already infected half the tree. In the absence of the secretary for development, Secretary for the Environment Edward Yau Tang-wah said the government would release in two weeks information on some 2,000 trees that were subject to detailed risk assessment by various departments. The information will specify the locations and problems with the unhealthy and risky trees. 'The Development Bureau hopes increasing the transparency of tree information will promote community-wide surveillance, thereby helping the government carry out its tree risk management work more effectively,' he said. Yau added that the Tree Management Office would order relevant government departments to improve tree management and that it had already reinforced its supervision over work on trees. He said officers from the tree office would randomly inspect the tree inspection forms completed by departments, and randomly inspect the condition of trees under the care of departments. Ken So Kwok-yin, a certified arborist and chief executive of the Conservancy Association , said disclosure of information on the 2,000 trees would improve transparency but he was worried about information on trees that were not on the list. 'Just take the big Chinese banyan tree situated outside the entrance to the central government's liaison offices' west wing, which collapsed a few days ago, as an example. It was not included in the list of the 2,000 trees,' he said. A pedestrian and a taxi driver were slightly injured when the tree fell amid heavy rain on Sunday. It was later found that 70 per cent of the tree roots were rotten. What the government should do now is step up its inspection of all trees across the city so that it might spot all the dangerous ones and deal with them immediately, So said.
