Patrol Pressure Increased Due to More than Doubled Nests of Oriental White Storks | Biodiversity Conservation in Our Neighborhoods (BCON)

As the weather gets warmer, migratory birds move northward in spring. On March 12th, volunteers from the waterfowl reserve in Tangshan City, Hebei Province and the staff of the State Grid Corporation of China,Tangshan, had a joint patrol around the Heiyanzi wetland where Oriental White Storks are relatively concentrated.

Heiyanzi wetland, located in Fengnan District, Tangshan City, is a part of Bohai Bay and an important transit point for the migration route of migratory birds from East Asia to Australia. Like other coastal wetlands around the Bohai Bay, the Heiyanzi area is relatively flat and has many water areas. It has always been the foothold of Oriental White Storks and other migratory birds.

Migratory birds migrate along the coast every year. Before the 1980s, there was little intersection with local people. However, after the middle and late 1980s, they have become increasingly close to each other, especially in recent years. In 1986, departments of State Grid Corporation of China,Tangshan began to build a 35 kV transmission and distribution line in Heiyanzi area, which was upgraded in 2003 but has not been put into use. In 2018, when the power department was preparing to start the line, it was found that Oriental White Storks had built nests on it, so the power transmission and distribution line was temporarily shelved.

During the patrol, the staff and the volunteers of CBCGDF found that the number of Oriental white stork nests has significantly increased along Qinbin highway by more than two times compared with last year: there were 8(including artificial nests) in 2019 and 7 (including artificial nests) 2021, whereas the number rose 15 (including artificial nests) this spring. Mr. Tian Zhiwei said that one of the new nests in the north was actually built on a 220 kV high-voltage transmission and distribution line .

Interestingly, among the Oriental White Storks that have built nests in Heiyanzi wetland, three nests have laid eggs, and the parents of storks in one nest have begun to hatch in turn.

During the patrol, we reinstalled the information bulletin board of wildlife protection responsibility in this wasteland. Later, when we asked about the situation from the local sheep herders, we learned that this large-area fish pond area may be gradually changed into paddy field this year. This possible change worries everyone. In recent years, more and more Oriental White Storks choose to nest here and no longer move north. One of the more important reasons is that this coastal wetland is mostly artificial fish ponds, which have less human interference, and fish ponds provide a rich source of food.

When CBCGDF conducted research in this area last autumn, the elm forest by a ditch near these high-voltage iron towers has become a breeding base for large groups of night herons due to less human interference. Local people say that there are few people in the fish pond area at present. But what if it is changed into a large-area paddy field? Will it greatly increase human interference and reduce the food source of Oriental White Storks at the same time? What impact will this have on the Oriental White Stork family, which has stayed here for several years?

In 2021, CBCGDF innovatively put forward the concept of Biodiversity Conservation in Our Neighborhoods (BCON), which aims to explore the best practices of effective biodiversity conservation in areas with intensive human activities, part-time protection and development, and coordinate sustainable livelihoods and biodiversity conservation. In the safe production of power grid, paying more and more attention to ecological protection is one of the concrete manifestations of BCON.
