282 The Environment

The Mai Po Marshes form one of the most important wildlife conservation sites in Hong Kong. Together with the Inner Deep Bay area, the Mai Po Marshes area has been listed as a 'Wetland of International Importance' under the Ramsar Convention. About 1 500 hectares of mudflats, fish ponds, marshes, reedbeds and dwarf mangroves provide a rich habitat for migratory and resident birds, particularly ducks and waders. Some 370 species of birds have been observed in this area. Many of these are considered globally threatened and endangered, such as the black-faced spoonbill, oriental stork, Nordmann's greenshank and

and Saunders's gull. The Agriculture, Fisheries and Conservation Department (AFCD) implements a wetland conservation and management plan to conserve the ecological value of the area.

The traditional fung shui woods near old villages and temples and the secondary forests provide important habitats for many woodland birds. Birds sighted in the wooded areas include warblers, flycatchers, robins, bulbuls and tits.

Areas around the Kowloon reservoirs are inhabited by monkeys which were released or which have escaped from captivity and their offsprings. There are breeding groups of rhesus macaques and a few long-tailed macaques, and their hybrids there. Some rhesus macaques have migrated to the forested areas of Shing Mun Reservoir and Tai Po Kau. Feeding of monkeys has been prohibited since July. 1999 to prevent their growth in numbers. Other mammals such as red muntjacs, leopard cats, East Asian porcupines, Chinese ferret badgers, masked palm civets, small Indian civets, Eurasian wild pigs are quite common in the countryside. Bats such as the Himalayan leaf-nosed bats, pomona leaf-nosed bats and Chinese horseshoe bats are found in caves and water tunnels. Sightings of less common species such as Eurasian otters, small Asian mongooses and Chinese pangolins are reported occasionally.

Hong Kong has over 100 species of amphibians and reptiles. There are 24 species of amphibians, and three of them the Hong Kong cascade frog, the Hong Kong newt and the endemic Romer's tree frog are protected under the Wild Animals Protection Ordinance. Most of the 52 species of snakes are harmless, and reports of people being bitten by highly venomous snakes are very rare. Among the 10 native species of chelonians, the green turtle is of particular interest as it is the only known species of sea turtle that is breeding in Hong Kong.

Marine Fauna

Hong Kong's subtropical marine environment supports species of both tropical and temperate climates. Local waters contain a wide diversity of fish, crustaceans, molluscs and other marine life, of which at least 150 species are of fisheries significance.

Situated on the eastern bank of the Pearl River estuary, Hong Kong receives fresh water from the river, especially in its western waters. The waters on the eastern side, on the other hand, are little influenced by the Pearl River outflow and are predominantly oceanic in nature. This unusual hydrography helps to contribute to the diversity of marine life.
