Flora of Indonesia
The "flora" consists of many unique varieties of tropical plants. Blessed with a tropical climate and around 17,000 islands, Indonesia is a nation with the second largest biodiversity in the world. The flora of Indonesia reflects an intermingling of Asian, Australian and the native species. This is due to the geography of Indonesia, located between two continents.
The archipelago consists of a variety of regions from the tropical rain forests of the northern lowlands and the seasonal forests of the southern lowlands through the hill and mountain vegetation, to subalpine shrub vegetation. Having the second longest shoreline in the world, Indonesia also has many regions of swamps and coastal vegetation. Combined together, these all give rise to a huge vegetational biodiversity.
There are about 28,000 species of flowering plants in Indonesia, consisting 2500 different kinds of orchids, 6000 traditional medicinal plants used as Jamu., 122 species of bamboo, over 350 species of rattan and 400 species of "Dipterocarpus", including ebony, sandalwood and teakwood.
Indonesia is also home to some unusual species such as carnivorous plants. One exceptional species is known as "Rafflesia arnoldi", named after Sir Thomas Stamford Raffles and Dr. Thomas Arnold, who discovered the flower in the depths of Bengkulu, southwest Sumatra. This parasitic plant has a large flower, does not produce leaves and grow on a certain liana on the rain forest floor. Another unusual plant is "Amorphophallus titanum" from Sumatra. Numerous species of insect trapping pitcher plants ("Nepenthes" spp.) can also be found in Borneo, Sumatra, and other islands of the Indonesian archipelago.
Tourism in Indonesia
With more than 17,508 islands, Indonesia presents ample diving opportunities. With 20% of the world's coral reefs, over 3,000 different species of fish and 600 coral species, deep water trenches, volcanic sea mounts, World War II wrecks, and an endless variety of macro life, scuba diving in Indonesia is both excellent and inexpensive. Bunaken National Marine Park, at the northern tip of Sulawesi, claims to have seven times more genera of coral than Hawaii, and has more than 70% of all the known fish species of the Indo-Western Pacific. According to Conservation International, marine surveys suggest that the marine life diversity in the Raja Ampat area is the highest recorded on Earth. Moreover, there are over 3,500 species living in Indonesian waters, including sharks, dolphins, manta rays, turtles, morays, cuttlefish, octopus and scorpionfish, compared to 1,500 on the Great Barrier Reef and 600 in the Red Sea. Tulamben Bay in Bali boasts the wreck of the US Army commissioned transport vessel, the . Other popular dive sites on Bali are at Candidasa and Menjangan.

Saronde Island is a very popular spot also in Gorontalo Sulawesi. Some of the most famous diving sites in Indonesia are also the most difficult to reach, with places like Biak off the coast of Papua and the Alor Archipelago among the popular, more remote, destinations for divers.
