Efforts are being made to prepare for the trial-operation of the Qinghair Tibet Railway in July 2006. This success reminds us of a man who contributes so much for the success of the "sky way".展开更多

This was achieved by studying the construction activities and operational phases of two pipelines with cumulative length of 165 km vis-à-vis the biodiversity of the affected area. The study involved field sampling along the RoWs to inventorize the fauna and flora, visual assessments and interview with locals. It was observed that the pipelines traversed moist lowland/freshwater swamp and mangrove forests, and barrier islands with approximately 4,950,000 m2 (equivalent of 495 hectares) of forest cleared and 9,642,000 trees killed to realize the pipelines. A total of 219 plant species in 66 families and 125 different fauna species from 64 families were recorded in these areas. Three out of the 4 recorded species of Meliaceae were threatened based on IUCN Conservation Status. Also based on IUCN Conservation Status, 20 mammals, including Pan troglodytes, Cercopithecus erythrogaster and Trichechus senegalensis, 7 birds, 2 reptiles and 1 amphibian were within threatened group. The results showed that the study area had witnessed colossal loss of biodiversity due to habitat displacement, forest fragmentation and deforestation, and escalated exploitation of species. The study identified the most affected biodiversity, and proffered measures to mitigate such occurrences.展开更多
