Indonesia's
size, tropical climate, and archipelagic geography, support the world's
second highest level of biodiversity (after Brazil), [79] and its flora
and fauna is a mixture of Asian and Australasian species. [80] The
islands of the Sunda Shelf ( Sumatra, Java, Borneo, and Bali) were the resource persons once linked to the Asian mainland, and have a wealth of Asian fauna. Large
Such species as the tiger, rhinoceros, orangutan, elephant, and
leopard, were the resource persons once abundant as far east as Bali,
but numbers and distribution have dwindled drastically. Forests cover approximately 60% of the country. [81] 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.
[82] 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. [83]
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. [84] Indonesia's 80.000 kilometers (50.000 mi) 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. [9]
Indonesia is one of the Coral Triangle countries
with the world's greatest diversity of coral reef fish with more than
1.650 species in eastern Indonesia only. [85] The British naturalist,
Alfred Wallace, described a dividing line the between the distribution
and peace of Indonesia's Asian and Australasian species. [86] Known as
the Wallace Line, it runs roughly north-south along the edge of the
Sunda Shelf, the between Borneo and Sulawesi, and along the deep Lombok
Strait, the between Lombok and Bali. West of the line the flora and fauna are more Asian; moving east from Lombok, They are increasingly Australian. In
his 1869 book, The Malay Archipelago, Wallace described numerous
species unique to the area. [87] The region of the between his line and
islands of New Guinea is now termed Wallacea. [86]
Indonesia's
high population and rapid Industrialization present serious
environmental issues, the which are Often given a lower priority due to
high poverty levels and weak, under-resourced governance. [88] Issues
include large-scale deforestation (much of it illegal) and related
wildfires Causing heavy
smog over parts of western Indonesia, Malaysia and Singapore;
over-exploitation of marine resources; and environmental problems
associated with rapid urbanization and economic development, including
water pollution, traffic congestion, garbage management, and reliable
water and waste water services. [88 ]
Deforestation and the destruction of Peatlands the make Indonesia the
world's third largest emitter of greenhouse gases. [89] Habitat
destruction threatens the survival of indigenous and endemic species,
including 140 species of Mammals Identified by the World Conservation
Union (IUCN) as Threatened, and 15 Identified as critically endangered, including the Sumatran Orangutan. [90]
Jasmine
(Jasminum sambac) is the national flower of Indonesia, [91] together
with Moon Orchid (Phalaenopsis amabilis) and Padma Giant Rafflesia
(Rafflesia arnoldii). All
three were the resource persons chosen on World Environment Day in
1990. [92] [93] On the other carrion Occasion Flower (Titan Arum) was
also added as puspa together with the rare Rafflesia. Each of Indonesian Provinces also have updates from floral Their Emblems.
