Mai Po Marshes

Mai Po Marshes (Chinese: 米埔濕地; Hong Kong Hakka: Mi³bu⁴ Sip⁵ti⁴) is a nature reserve located near Yuen Long in Hong Kong. It is part of Deep Bay, an internationally significant wetland that is actually a shallow estuary, at the mouths of Sham Chun River, Shan Pui River (Yuen Long Creek) and Tin Shui Wai Nullah. Inner Deep Bay is listed as a Ramsar site under Ramsar Convention in 1995, and supports globally important numbers of wetland birds, which chiefly arrive in winter and during spring and autumn migrations. The education center and natural conservation area is 380 acres (1.5 km²) wide and its surrounding wetland has an area of 1500 acres (6 km²). It provides a conservation area for mammals, reptiles, insects, and over 350 species of birds.

The reserve is managed by the World Wide Fund for Nature Hong Kong since 1983; the Agriculture, Fisheries and Conservation Department has responsibilities for the Ramsar site as a whole. Deep Bay faces threats, including pollution, and rising mudflat levels that perhaps arise from intense urbanization, especially (in recent years) on the north, Shenzhen side of the bay.
