  Hong Kong is on China's southern coast, 60 km (37 mi) east of Macau, on the east side of the mouth of the Pearl River estuary. It is surrounded by the South China Sea on all sides except the north, which neighbours the Guangdong city of Shenzhen along the Sham Chun River. The territory's 1,110.18 km (428.64 sq mi) area (2,754.97 km if the maritime area is included) consists of Hong Kong Island, the Kowloon Peninsula, the New Territories, Lantau Island, and over 200 other islands. Of the total area, 1,073 km (414 sq mi) is land and 35 km (14 sq mi) is water. The territory's highest point is Tai Mo Shan, 957 metres (3,140 ft) above sea level. Urban development is concentrated on the Kowloon Peninsula, Hong Kong Island, and in new towns throughout the New Territories. Much of this is built on reclaimed land; 70 km (27 sq mi) (6% of the total land or about 25% of developed space in the territory) is reclaimed from the sea.
  
  Undeveloped terrain is hilly to mountainous, with very little flat land, and consists mostly of grassland, woodland, shrubland, or farmland. About 40% of the remaining land area is country parks and nature reserves. The territory has a diverse ecosystem; over 3,000 species of vascular plants occur in the region (300 of which are native to Hong Kong), and thousands of insect, avian, and marine species.
