Wetlands of Hong Kong

There are few natural wetlands in Hong Kong. The Mai Po Marshes is the biggest in them and the most famous of all. Most wetlands in Hong Kong are unused farm land, such as the Long Valley wetland (塱原濕地).

Biodiversity is a concern in these wetlands, and therefore there are often concerns about construction around wetlands. This is why the KCR built part of the Lok Ma Chau Spur Line underground to cross the Long Yuen Wetland.
