Takeaways

• 😀 Indonesia is home to the highest biodiversity in the world, with various biomes such as tropical rainforests, savannas, and coastal areas.
• 🌍 Indonesia's location on the equator allows it to receive sunlight year-round, contributing to high rainfall and supporting diverse ecosystems.
• 🌸 Indonesia’s tropical rainforests are known for their endemic plants, such as the Rafflesia arnoldii, Meranti, Sandalwood, and various orchids.
• 🧭 The distribution of flora and fauna in Indonesia is divided based on two key lines: Wallace's Line and Weber's Line.
• 📍 Wallace's Line, introduced by Alfred Russell Wallace in 1859, separates the fauna of Asia and Australia.
• 🌏 Weber's Line, proposed by Max Carles Wilhelm Weber in 1919, divides the fauna of the Sunda and Sahul Shelves.
• 🦏 Indonesia's fauna is classified into three regions: Asiatic (west), transitional (central), and Australasian (east).
• 🐅 Fauna in the Asiatic region (west Indonesia) includes large mammals like the Sumatran elephant, tiger, and one-horned rhinoceros.
• 🦘 The Australasian region (east Indonesia) is home to smaller mammals, marsupials, and colorful birds, such as kangaroos, wallabies, and cassowaries.
• 🌳 The transitional region, including Sulawesi and Nusa Tenggara, hosts endemic animals like tarsiers, Komodo dragons, and the Celebes bear.
• 🌱 Indonesia's flora is also divided into three regions: Sunda Shelf (Asia influence), Sahul Shelf (Australia influence), and transitional regions, with many endemic plant species like Rafflesia arnoldii and the Black Orchid of Kalimantan.

Q & A

What is the significance of Indonesia's biodiversity?

Indonesia is known for having the highest biodiversity in the world, thanks to its diverse biomes, including tropical rainforests, savannas, and coastal areas, supported by its geographic location near the equator, receiving consistent sunlight and high rainfall.

What are some examples of endemic plants found in Indonesia?

Examples of endemic plants in Indonesia include Rafflesia arnoldii, Meranti, Sandalwood, Umbrella Tree, and Damar, among others.

What is the role of Wallace's Line and Weber's Line in classifying Indonesia's fauna?

Wallace's Line and Weber's Line are imaginary lines used to separate Indonesia's fauna into different regions. Wallace's Line divides the fauna of Asia and Australia, while Weber's Line further divides the fauna of the Sunda and Sahul shelves.

What are the three regions based on fauna distribution in Indonesia?

Indonesia's fauna distribution is divided into three regions: the Asiatic fauna region (west Indonesia), the Australasian fauna region (eastern Indonesia), and the transitional fauna region (Sulawesi and Nusa Tenggara).

Which animals are characteristic of the Asiatic fauna region in Indonesia?

Characteristic animals of the Asiatic fauna region include large mammals like the Sumatra elephant, Sumatran tiger, and one-horned rhinoceros, as well as primates like the Bornean orangutan, Tapanuli orangutan, and Siamang.

What examples of animals are found in the Australasian fauna region of Indonesia?

In the Australasian fauna region, examples of animals include smaller mammals like the Anoa, koala, and Irian land porcupine, as well as marsupials like the Wallaby, Kangaroo, Sugar Glider, and the Kangaroo Rat.

What is the transitional fauna region in Indonesia, and what animals are found there?

The transitional fauna region includes Sulawesi and Nusa Tenggara, where animals like the Tarsier, Komodo dragon, Cuscus, Bear, and Rusa deer can be found.

How is the flora in Indonesia categorized?

Indonesia's flora is categorized into three regions: the Sunda Shelf (Sunda region), the Sahul Shelf (Sahul region), and the transitional flora region, with each region influenced by either the Asian or Australian continents.

What are some examples of endemic plants in the Sunda Shelf region of Indonesia?

Endemic plants in the Sunda Shelf region include Rafflesia arnoldii (found at the border of Bengkulu, Jambi, and South Sumatra), Tien Soarto orchid (found in North Sumatra), and Black Orchid (found in Kalimantan).

What are the characteristics of the flora in the Sahul Shelf region of Indonesia?

The flora of the Sahul Shelf is influenced by the Australian continent and includes species like Merbau, Matoa, Sago, and Ebony. The region also has tropical rainforests that are lush and remain green year-round.
