Types of Coastal Wetlands in Macao
Macau’s coastal wetlands are vital ecosystems where the land meets the sea. They can be broadly categorized into two types based on salinity and landscape: Saline Wetlands, such as rocky intertidal zones, and Brackish Wetlands, which include mangrove forests and coastal lagoons.
These wetlands play a vital role in protecting Macau’s natural and urban environments. They act as buffers, shielding shorelines from erosion and storm surges caused by extreme weather. These wetlands also help improve water quality by filtering pollutants from surface runoff before it reaches the ocean. In addition, they provide essential habitat for a wide variety of species, including threatened and migratory birds, fish, and marine mammals. Beyond their ecological value, coastal wetlands serve as natural carbon sinks, capturing and storing carbon dioxide, which contributes to the fight against climate change.
Saline Wetlands – Rocky Intertidal Zones
These wetlands are exposed directly to the open sea and are influenced by tidal changes and high salinity. Explore rugged coastal zones where waves crash against rocks and marine life clings to the shore. These areas are also known for sightings of the Chinese White Dolphin.

Brackish Wetlands – Mangroves and Lagoons
Brackish wetlands form in areas where freshwater mixes with seawater. These ecosystems often develop into tidal mudflats and mangrove forests that provide crucial nurseries for fish, crustaceans, and birds. While most brackish wetlands occur naturally, There are man-made brackish lagoon here in Macao.
