Recommendations for the protection of vegetation on and around the site, including control of the erosion and run off from the construction site were proposed and implemented, resulting in effective protection of the local vegetation cover. Stream macrobenthos were low in species diversity and abundance and did not show a changing trend during the construction and the operation of the land fill. Birds attracted to the active dumping site were dominated by Crested Mynah Acridotheres cristatellus and the Tree Sparrow Passer montanus. After an increase in the population during the warmer months, the number of birds seen on the land fill site decreased to 10 in December 1994. Mammal monitoring by live trapping revealed that the rat population did not increase after the land fill operation started. This project was the first comprehensive’ ecological study and monitoring of an urban land fill in Hong Kong and it demonstrated that careful environmental planning and implementation of mitigation measures can successfully limit environmental impacts of landfills to acceptable levels.展开更多
