China, Yellow River Wing
The Yellow River Delta (YRD) Wing of the Delta Alliance was officially established in October 2015, with Beijing Normal University (BNU) acting as the coordinating agency, and participating organizations comprise Yellow River Delta National Natural Reserve (YRDNNR) Administration Bureau, National Bird Banding Center of China and Beijing Forestry University. Prof. Dongdong Shao from BNU is currently serving the Wing Coordinator.
Yellow River Delta
The Yellow River is the sixth longest river in the world and the second longest river in China. As a result of frequent avulsion of the river course, the Yellow River Delta (YRD) has experienced dramatic changes in the past two thousand years. The present delta is located in the northeast of Shandong Province. It covers a total area of 18000 km² with a population of 5.2 million people. The YRD is rich in natural resources, with the second largest oil field of China (the Shengli Oil Field) situated in the delta. At the same time, the YRD contains important wetland ecosystem, which is the habitat for numerous species, including millions of migrating birds of which many are under protection.

In this study, we show that pressure from natural enemies regulates an ecosystem’s resilience to severe droughts. Field experiments revealed that in protected salt marshes experiencing a severe drought, plant-eating grazers eliminated drought-stressed vegetation that could otherwise survive and recover from the climate extreme, transforming once lush marshes into persistent salt barrens. Our study highlights that natural enemies can hasten an ecosystem’s resilience to drought to much lower levels than currently predicted, calling for integration into climate change predictions and conservation strategies.

In this special issue, we synthesize current understanding of environmental changes and human impacts on China’ coastal wetlands, focusing on reclamation. For some of those impacts, new models and indices are developed or applied. We also outline key research areas that should be further studied for effective management of coastal wetlands and successful wetland restoration.

A multifaceted dataset was compiled to quantify coastal trends and examine the role of economic growth in China's coastal degradation since the 1950s. All 15 coastal human impacts examined increased over time, especially after the 1978 reforms. Economic growth has been proved the cause of accelerating human damage to China's coastal ecosystems. Without strict conservation efforts, continuing economic growth will further degrade China's coastal ecosystems
