THE ENVIRONMENT

Protection Bureau and the Shenzhen authorities. A delegation from the bureau visited Hong Kong in January and the Hong Kong Government paid a return visit to Guangdong in November. These visits resulted in useful talks on mutual problems with areas for possible future collaboration identified.

Conservation and Countryside Management

Hong Kong's hilly topography has ensured the survival of a relatively large expanse of countryside, much of which is scenically very attractive. Steep and rugged slopes rise from sea-level to 600 and 900 metres and feature rocky crags, wooded ravines with rushing streams, and open hillsides. Some 20 freshwater reservoirs of various sizes nestle among the hills, giving additional charm to the scenery.

About 75 per cent of Hong Kong's land area consists of hills and the vegetation on them includes grass, scrub, and some 125 square kilometres of woodland - much of it the result of afforestation programmes. The woodlands not only make the countryside more beautiful but are important in the management of water catchments.

The Agriculture and Fisheries Department is the principal government agency responsible for conserving the territory's countryside. The Country Parks Ordinance, which came into effect in early 1976, provides for the designation, control and management of the most important areas of countryside as country parks, and enables them to be developed for recreational purposes. It also gives particular protection to vegetation and wildlife. There are now 21 country parks throughout Hong Kong, covering about 40 per cent of the land area.

Within these country parks, recreational amenities include picnic and barbecue places, waymarked walks, shelters, toilets, and information and educational services. Road access is also being improved to enable park staff to deal more effectively with fires and litter – the most serious problems created by visitors.

The department also has the responsibility for protecting the flora and fauna throughout the whole of Hong Kong. The Forests and Countryside Ordinance provides for the general protection and management of vegetation, and special protection is given to certain plants including native camelias, magnolias, orchids, azaleas and the Chinese New Year Flower.

The Wild Animals Protection Ordinance prohibits hunting of wild animals and restricts the entry of unauthorised members of the public into two important wildlife habitats, the Mai Po Marshes and the Yim Tso Ha Egretry. Overall enforcement of the ordinances is carried out by park rangers, park wardens and nature wardens. These officers also provide information at visitor centres and at ranger posts and escort groups on guided visits.

In addition to general conservation of the countryside, Hong Kong has now adopted the concept of identifying and conserving sites of special scientific interest to ecologists, such as a site where a rare tree or a rare species of butterfly can be found. More than 40 sites have been identified for future conservation action.

Topography and Geology

Hong Kong is part of an ancient Cathaysian landmass that some 1 000 million years ago extended from Shandong (Shantung) in northern China to the Gulf of Hainan. Following intensive folding of its metamorphic and crystalline rocks, intense mountain-building occurred with granitic and volcanic intrusions during the Mesozoic period, about 250 million years ago. From the beginning of the Quaternary period, between two to three million years ago, the lower-lying areas were alternately flooded or exposed as masses of water were locked up or released from ice sheets. The last marine incursion was about
