Dongbai Marsh

Gazing upon the vast expanse, can you sense the whispers of the Dongbai Marsh? This remarkable wetland, nestled on the eastern edge of Chongming Island, holds a special place in Shanghai’s natural heritage. Dongbai Marsh is not just any marsh. It represents the largest and only remaining natural mudflat on the Yangtze estuary. This unique ecosystem thrives within the intersection of the Yangtze River, the Yellow Sea, and the East China Sea. Imagine the vibrant tapestry of life it supports. Dongbai Marsh boasts flourishing mudflat vegetation, a network of tidal creeks, and a rich diversity of benthos. These plants, including the common Phragmites and the endemic Scirpus mariqueter, aren’t just pretty. They play a crucial role in enriching primary productions, purifying the water, and protecting the coastline from erosion and storm tides. Dongbai Marsh is a crucial stopover and wintering site for 111 species of migratory waterbirds. Among them are some of the world’s most threatened species. The critically endangered spoon-billed sandpiper, the endangered black-faced spoonbill, and the vulnerable hooded crane all find refuge here. The waters teem with life too. Ninety-four species of freshwater, seawater, and migratory fish call Dongbai Marsh home. That represents over 80% of the total Yangtze estuarine fish species. This includes the critically endangered Chinese sturgeon. Designated a Ramsar site in 2002, Dongbai Marsh covers a vast area of 32,600 hectares. It’s a testament to the importance of preserving these delicate ecosystems. As you stand here, on the edge of this natural wonder, take a moment to appreciate its beauty and significance. Dongbai Marsh, a testament to the delicate balance of nature, thrives in the heart of a bustling metropolis. It serves as a reminder of the rich biodiversity that can exist even in the most urban environments.
