On the morning of April 19th, a meeting was held in Nanchang, Jiangxi Province, regarding the prognosis for the bird collision incidents that occurred along the section of the Wuhan-Nanchang Double Circuit 1000kV Transmission Line Project around Poyang Lake. During the meeting, Dr. Jinfeng Zhou, Secretary General of the China Biodiversity Conservation and Green Development Foundation, delivered a speech emphasizing that the resolution of bird collision issues around Poyang Lake should be based on solid research conducted by independent third parties, leading to professional solutions.

Dr. Zhou stated that the publicly disclosed data on bird deaths resulting from this year’s migratory season along the Wuhan-Nanchang Double Circuit 1000kV Transmission Line Project around Poyang Lake only represents a portion of the known bird mortality figures. He highlighted the severity of the situation, noting that it includes birds not ringed, as well as wild birds that are not cranes. Despite the efforts undertaken by various parties over the past four years regarding this national key project, Dr. Zhou stressed that the outcome of a significant number of deaths of nationally protected wildlife due to this project is unacceptable.

Regarding the emergency prognosis proposed by the State Grid Corporation, Dr. Zhou urged the relevant construction units to earnestly commission third parties to independently conduct a bird survey of the Wuhan-Nanchang Double Circuit 1000kV Transmission Line Project around Poyang Lake, particularly during the autumn and winter seasons. Based on a comprehensive understanding of the facts and combining various professional opinions, a series of professional biodiversity protection solutions should be proposed. “The prognosis should not only focus on protective measures along the relevant transmission line project segment but also take a holistic approach to develop comprehensive prognostic measures,” said Dr. Zhou.
Furthermore, given the unique scenarios at the bird collision segment of the Wuhan-Nanchang Double Circuit 1000kV Transmission Line Project, such as lake and farmland habitats, protected area management, and non-protected area management, Dr. Zhou hoped that behaviors and habitat rules of the migratory birds in this wintering area could be thoroughly understood and resolved through preliminary independent investigations, enabling broader research on larger platforms. He also suggested the potential involvement of international crane research experts in this study. Dr. Zhou emphasized that preventive measures before the arrival of this year’s migratory season, especially temporary measures proposed by some units such as laser treatment and sound wave control, should undergo systematic environmental assessments in the future. This assessment should evaluate the intensity of light and sound produced by these measures and their impacts on the wintering behaviors of migratory birds and their habitats. “Only through comprehensive and scientific assessments can we determine the effectiveness of physical control measures,” Dr. Zhou concluded, highlighting the necessity of evaluating these measures beyond singular physical performance characteristics like penetration distance and diffusion impact range.
