Recently, International Biodiversity Day (Zhejiang) 2025 for Demonstration Zone of Green and Integrated Ecological Development of the Yangtze River Delta was held, announcing the sixth biodiversity experience sites of Zhejiang and the outstanding biodiversity conservation cases for 2025. The Scenic Area of South-north Lake was included.

The core of this scenic area boasts rich natural and cultural resources. Bordering Hangzhou Bay and surrounded by mountains on three sides and the sea on one side, this scenic area is a key stopover along the East Asian-Australasian Flyway for migratory birds. Every April and October, over 160 species of birds, including songbirds, raptors and waders pause here to rest and forage. To date, this scenic area has documented four species of national first-class protected animals and nearly 20 species of national second-class protected animals.
