Where Have All the Relict gulls Gone? Ecosystem Self-recovery Cannot Be Ignored | PAOBI053

The Relict gull (Larus relictus) is listed in the IUCN Red List as Vulnerable Species. Bagua coastal mudflat in Tianjin Binhai New Area, where provides abundant food for the wintering Relict gull and other seabirds, is a Conservation area for Relict gulls.

 


Recently, it is reported that the number of migratory birds such as relict gulls in the coastal mudflat from the Fengnan boundary of Bagua coastal mudflat in Binhai New Area to the estuary of Yongding New River is significantly less than that in previous years. According to the historical monitoring data, the number of relict gulls in March 2021 exceeded 4,500, March in 2022 exceeded 5,000, the number in Marich 2023 was only about 1,000, and the number in March 2024 is less than 100.

 

Information shows that this section is located in the first phase of “Tianjin Marine Ecological Protection and Restoration Project” of the District Oceanic Bureau. The construction started in September 2022 and has passed the project completion acceptance and evaluation by the end of August 2023.

 

The purpose of marine ecological protection and restoration projects is to restore the functions of coastal wetland ecosystems, protect migratory bird habitats, improve the carrying capacity of wetlands for organisms, and maintain wetland biodiversity. However, from the current situation of restoration, the effectiveness of the project has not been showns, and it is even more worrying than before.

 

Here are some suggestions for ecological restoration:

 

Firstly, the restoration must truly adhere to the principle of natural restoration as the mainstay and artificial restoration as a supplement. The ecological base and background should not be easily disturbed.

 

Secondly, real-time monitoring during the repair process is essential, and implementation plans should be modified in a timely manner based on monitoring results, putting life first.

 

Thirdly, the dynamic monitoring after restoration should not be delayed. An annual post evaluation should be conducted to create a continuous ecological monitoring map and track the restoration effect in the long term.

 

Finally, before proceeding with restoration, it is necessary to further evaluate the self- recovery ability of the ecosystem.
