Impact of Electric Power Grid Projects on Bird Diversity and the Suggestion of Bird Conservative Technology

The increasing number of power lines each year has a significant impact on bird biodiversity, while the control of birds at high risk from power grid projects is a guarantee of safe and reliable power grid operation. From both the perspective of safety and biodiversity conservation, how to achieve harmonious coexistence between birds and power grid projects has become an urgent scientific problem to be solved. This study investigates the impact of power grid projects on bird diversity by investigating birds in and around power grid projects in Fujian Province, and proposes suggestions for power grid projects to protect bird diversity. The results show that future power grid projects should try to avoid increased forest fragmentation, and temporary construction roads should be restored as soon as possible in order to preserve animal passage. The affected migratory birds in the power grid deployment area under study are mainly finches and a few raptors, and according to the migration pattern of these two types of birds, construction during the bird migration season in March and October should be avoided as much as possible during the construction of power grid, especially the night-time construction of large converter stations and substations.
