Rain Forests of Indonesia

Climate of the Indonesian Rain Forest

Average Rainfall: 9.8 to 7.1 inches per month

Average Temperature: 89F average maximum with a 77F average minimum

The tropical rain forests, including ones located in Indonesia, are a very humid and warm biome. Temperatures never dip blow 64 degrees and rainfall usually reaches around 66 inches per year. This extremely wet and hot environment contributes to the diversity of the animal life found here.

Net Primary Productivity:

The Indonesian rain forests are generally found within 10 degrees north or south of the equator. The rain forests are considered quite diverse, due to the large number of niches that exist in it relative to other biomes.. Compared to the other biomes, tropical rain forests have high productivity, mainly due to the high rainfall totals and the fact it never freezes.

Soil Quality

Soil quality in the Indonesian rain forests is among the worst in the world. Contrary to what many people thought (Due to the sheer number of plants in the biome), the amount of organisms in the biome depletes resource almost immediately, which means farming is basically impossible.

Invasive and Endangered

Endangered: Sumatran Tiger

The Sumatran tiger is found exclusively on the Indonesian island of Sumatra. It has experienced habitat destruction, population control, climate change, and finally over-harvesting of its prey.

Invasive Species: Common Water Hyacinth

The Common Water Hyacinth is considered one of the most invasive plants in the world. It has devastated Indonesian Rain Forests through the way it absorbs oxygen through the water, which leaves it so fish cannot breathe. Also when growth is not controlled it can cover entire lakes or ponds.

Animals in the biome.

Sumatran Ground Cuckoo

The Sumatran ground cuckoo is adapted to live in the rain forest due to its' small nature and its' camouflage like coat of feathers.

Sumatran Elephant

The Sumatran Elephant is adapted to live in the rain forests due to its quick birth, which allows for the babies to stand only 20 minutes after birth. Also, the useful trunk allows the elephant to get stuff in hard to reach places.

Sumatran Orangutan

The Sumatran Orangutan is adapted to the rain forest due to its omnivorous nature. It is also known for its quick movement, to escape predators like the Sumatran tiger, and its' use of tools.

Plants in the Indonesian Tropical Rain Forests

Rafflesia Arnoldii

This plant is adapted to live in the rain forest due to the pungent odor it creates, which is considered to smell like a corpse, to attract flies which then pollinate it.

Titan Arum

The titan arum is much like Rafflesia arnoldii, in that they are both large flowers that attract pollinators due to a corpse-like scent. 

Sumatran Pine

The Sumatran pine is adapted to Sumatra in that its' lengthy pine needles (15-20cm long) can travel long distances to spread the tree around a wide location.
