Indonesia, officially the Republic of Indonesia (Indonesian: Republik Indonesia Indonesian pronunciation: [rɛpublik ɪndonesia]), is a sovereign state in Southeast Asia and Oceania. Indonesia is an archipelago comprising thousands of islands. It encompasses 33 provinces and 1 Special Administrative Region (for being governed by a pre-colonial monarchy) with an estimated population of over 252 million people, making it the world's fourth most populous country. Indonesia's republican form of government comprises an elected legislature and president. The nation's capital city is Jakarta.
Indonesia lies between latitudes 11°S and 6°N, and longitudes 95°E and 141°E. It consists of 17,508 islands, about 6,000 of which are inhabited. These are scattered over both sides of the equator. The largest are Java, Sumatra, Borneo (shared with Brunei and Malaysia), New Guinea (shared with Papua New Guinea), and Sulawesi. Indonesia shares land borders with Malaysia on Borneo, Papua New Guinea on the island of New Guinea, and East Timor on the island of Timor. Indonesia shares maritime borders across narrow straits with Singapore, Malaysia, the Philippines, and Palau to the north, and with Australia to the south. The capital, Jakarta, is on Java and is the nation's largest city, followed by Surabaya, Bandung, Medan, and Semarang.
Indonesia's size, tropical climate, and archipelagic geography, support the world's second highest level of biodiversity (after Brazil), and its flora and fauna is a mixture of Asian and Australasian species. The islands of the Sunda Shelf (Sumatra, Java, Borneo, and Bali) were once linked to the Asian mainland, and have a wealth of Asian fauna. Large species such as the tiger, rhinoceros, orangutan, elephant, and leopard, were once abundant as far east as Bali, but numbers and distribution have dwindled drastically. Forests cover approximately 60% of the country. In Sumatra and Kalimantan, these are predominantly of Asian species. However, the forests of the smaller, and more densely populated Java, have largely been removed for human habitation and agriculture. Sulawesi, Nusa Tenggara, and Maluku – having been long separated from the continental landmasses—have developed their own unique flora and fauna. Papua was part of the Australian landmass, and is home to a unique fauna and flora closely related to that of Australia, including over 600 bird species.
Indonesia is second only to Australia in terms of total endemic species, with 36% of its 1,531 species of bird and 39% of its 515 species of mammal being endemic. Indonesia's 80,000 kilometers (50,000 miles) of coastline are surrounded by tropical seas that contribute to the country's high level of biodiversity. Indonesia has a range of sea and coastal ecosystems, including beaches, sand dunes, estuaries, mangroves, coral reefs, sea grass beds, coastal mudflats, tidal flats, algal beds, and small island ecosystems.
