Astonishingly Dajinshan Hill stands tall. It is the highest point in Shanghai. Towering 103.4 meters above sea level it offers breathtaking views. This remarkable hill is more than just a geographical landmark. Dajinshan Hill is a vital part of the Jinshan Three Islands Marine Ecological Nature Reserve. It shares this protected status with Xiaojinshan Island and Fushan Island. Together they form Shanghai’s first marine ecological reserve.
The history of Dajinshan Hill is rich and intriguing. Long ago during the reign of Emperor Kang of the Western Zhou Dynasty a fortress stood on its northern slopes. This ancient structure was known as Jinshan City. Over centuries rising sea levels and coastal erosion separated the area from the mainland. This process ultimately created the islands we see today in Hangzhou Bay.
Dajinshan Hill boasts exceptional biodiversity. It holds the title of Shanghai’s largest native plant gene bank. Over sixty rare plant species thrive there. These plants have vanished from mainland Shanghai. Nationally protected species like Neolitsea sericea and Cinnamomum japonicum also call the hill home. Thirteen of Shanghai’s largest ancient trees including the Chinese hackberry and the mulberry are found here.
The wildlife is equally diverse. A 2017-2018 survey recorded fifty-one bird species. Several are nationally protected including the Chinese sparrowhawk black kite and common kestrel. Over one hundred macaques another nationally protected species live on the hill. These macaques were introduced in the 1980s and have since thrived in the wild. Various snakes including the red-banded snake king ratsnake and the rare two-headed blunt-tailed snake also inhabit the area. The discovery of the two-headed blunt-tailed snake increased the number of known snake species in Shanghai to sixteen.
The Shanghai Oceanic Bureau actively works to protect Dajinshan Hill’s unique ecosystem. Ecological trails have been built for research. Scientific equipment monitors rainfall insect populations and other vital data. Strict ecological management is in place. The reserve is not open to the public except for occasional open days during Shanghai International Nature Conservation Week. Dedicated guardians protect the island ensuring its pristine environment remains undisturbed. They even feed the macaques regularly bringing food from the mainland.
Dajinshan Hill is a treasure a testament to nature’s resilience. Its biodiversity its history and its ongoing conservation efforts make it a truly remarkable place. It is a reminder of the beauty and importance of preserving Shanghai’s natural heritage.
