The MTR Corporation came under fire again in September 2011 after felling dozens of trees in Admiralty as part of construction work for the South Island line. Green activists denounced the tree felling as "unprofessional", and Ken So Kwok-yin, chief executive of the Conservancy Association and a certified tree arborist, said that the explanations offered by the MTR Corporation as to why the trees were felled were "unacceptable". The MTR Corporation is felling approximately 4,000 trees for the construction of the South Island line, raising concerns from environmental groups and the public about its commitment to protecting Hong Kong's natural environment.
