Under exceptional circumstances, the regional government may ask the central government for assistance from the garrison in disaster relief . </P> <P> Residents of Hong Kong are not required to perform military service . Current law has no provision for enlistment of local residents, meaning that the military force defending the territory is composed entirely of personnel originating outside of Hong Kong . As responsibility for the defence of Hong Kong rests solely with the central authority, the regional government is not obligated to bear the expenditures of the garrison stationed in the city . During the colonial era, territorial defence was the responsibility of the British Forces Overseas Hong Kong, supplemented by local militia organized as the Royal Hong Kong Regiment . The only military - affiliated organisation that recruits local residents is the Hong Kong Army Cadets Association, a uniformed youth organisation of children aged 6 and older sponsored by the People's Liberation Army . </P> <P> Hong Kong is located on China's south coast, 60 km (37 mi) east of Macau on the opposite side of the Pearl River Delta . It is surrounded by the South China Sea on the east, south, and west, and borders the Guangdong city of Shenzhen to the north over the Sham Chun River .

About 40% of the remaining land area is reserved as country parks and nature reserves . Low altitude vegetation in Hong Kong is dominated by secondary rainforests, as the primary forest was mostly cleared during the Second World War, and higher altitudes are dominated by grassland . The territory is highly diverse: over 3,000 species of vascular plants occur in the region, 300 of which are native to Hong Kong . Over 2,000 species of moths, butterflies, dragonflies, and other insects can be found, as well as one third of the total bird species in China, and a variety of fish, amphibians, reptiles, and mammals native to the Pearl River Delta .
