Sumatran Tigers – Facts and Conservation

Animals, wild animalsSumatran Tiger is a subspecies which only can be find in Sumatra Island. It has a smallest body other than tigers in the world. It lengths only up to 2.5 meters. Therefore, their small size allow them to move in forests. The Appearance of Sumatran tigers is different from other species.

Sumatran tiger is a carnivores. It dominants as predator which eat meat. The size and strength allow them to hunt their prey effectively. Then Sumatran tiger have no enemies in their natural environment. Human is the only threat to the existence of Sumatran tiger. Human who hunt and eliminate make tiger includes as one of critically endangered species.

Sumatran tiger is one of six subspecies which still survive until now. The population is about 400-500 tigers mainly in national park of Sumatra Island. Sumatran tiger is an important predator to keep the balance of food chain. Especially in the forest of Sumatra Island. However, It unlike with other species which live in groups. Most of them are living alone, except during childbearing.

Then, the tiger developed in eastern in China and Siberia. The two became separated. One of them moves to central Asia towards the western forest then southeast Asia and Indonesia. Meanwhile, the others move to India to the west.

Meanwhile, Sumatran tiger believed as species which alienated during sea levels are rising about 6,000 until 12,000 years ago. Then research proved that Sumatran tiger has unique genetic which different from the others. Therefore, It likely to develop into separate species with sustainable management.

Sumatran tiger is one of endemic animals in Indonesia. Endemic means natural habitat species which inhabit a particular area. They make the area becomes themselves and unlike other areas.


People of Sumatra island usually called Sumatran tiger as small cat. It because their height and weight are similar like cat.

The color of stripes

The main patterns of Sumatran tiger are mix colors between reddish to pale yellow. It include black and white camouflages as main feature. Each tiger is different as well as their both sides. The amount of camouflages are also different. Then the thickness tend to split or spotted.

Reproduction of Female Sumatran Tiger

Female Sumatran tiger are breeding anytime. Their period of gestation is about 103 until 110 days. Tigers give a birth up to two or three child at once. Then the new baby born tiger open their eyes after 10 days of day birth.

The children only drink their mother’s milk in the first eight weeks. Meanwhile, They can hunt themselves at the age of 18 months. Female Sumatran tiger led their child by themselves at 2 years old. Therefore, Sumatra tigers can live for 15 years in the wild forest. Moreover, It last until 20 years depend on their capability.

Reproduction of female Sumatran Tiger is under controlled by breeder. It means that mix and separate between male and female tiger are based on breeder decision. However, there is no tiger lives forever with one pair. It is based on several reasons include restrictions of population growth. It purposes to avoid inbreeding as a result of a very small population of Sumatran tigers.

The Estrus Cycle

Generally, the female Sumatran tigers entered estrus cycle around 30-40 days with a long estrus between four until eight days.  At the time, the estrus of female Sumatran tigers can perform up to 40 times of copulation.

Therefore, the marriage between tigers will always be monitored until male and female tigers transferred to a group which has unrelated blood. Nowadays, It still continuously to increases the population by takes into a diversity of genetic variation.

The aspect of reproduction is not an issue for group of tigers. Meanwhile, if the breeding population has reached maximum level, several problems related to reproduction will arise. It mainly how to decide either tigers are allowed to actively reproduce.

Moreover, Sumatran tiger has a high chance of giving birth throughout the year. However, the optimum potential of tigers based on capability terms has not been utilized. The management still has problem between in order to avoid marriage and reduce the cost of care. Therefore, the high rate of deaths under the age still need to get concern.

Natural Habits

Tigers usually live solitary except for females and children. Meanwhile, they are not anti-social. Male tiger will giggling around with female tiger during marriage session. There are also captured together with their children. Unlike most other types of cats, tigers easily enter the water. During the summer, they will take a dip in a lake or pond.

The Sumatran tiger is only found on the island of Sumatra island. This big cat was able to live anywhere. It between lowland forests to mountain forests. They live in many wild places. There are 400 Sumatran tiger who lives in nature reserves and national parks. Meanwhile, the rest are scattered in other areas were cleared for agriculture. Therefore, It approximately 250 tails are kept in zoos around the world.

Meanwhile, The Sumatran tiger faces the threat of losing their habitat due to distribution area. It areas include blocks of lowland forests, peat lands, and rain forest. As well as encroachment by logging and road building. Therefore, they often go closer with humans and killed or arrested if encounters with humans.

Tiger basically not prey on humans unless their habitat is disturbed, elderly, sick or injured. Some victims occurred as a reaction to defend themselves. Then human body becomes their food. Human is easily target than animals as a prey. Somehow, Tigers prey on humans may teach their children that humans are prey. However, a tiger who protect her child is not include as indication.

Riau province is home for 1/3 of the entire Sumatran tiger population. Even though they are already under protected, the existence of Sumatran tiger has declined dramatically. It up to 70 percents in last quarter of century. Moreover, In Riau, there are only the remaining 192 tigers currently estimated.

Sumatran tigers choose their food depends on where they live and amount of prey. As the primary predator in the food chain, Tigers maintain the population of wild prey under their control. So, the balance between prey and vegetation can be maintained.

Tiger has a very sharp sight and hearing. It claimed themselves as efficient hunter. They hunt at night and eat anything that can be captured.

The preys of tigers commonly wild animals. Mostly wild bears and deer. Sometimes poultry and fishes. Orangutans also become their prey. However, Orangutans rarely spent time at ground level. Therefore, It difficult for tiger captures them. Sumatran tigers also known as Durian mania.


Sumatran tigers are on the edge of extinction. It because their habitats are uncontrolled, The preys for tigers are no longer exist, and illegal hunting. In 2008, a report released by TRAFFIC. It is a program of the WWF (World Widelife Fund) and the World Conservation Agencies called IUCN. Both were monitored illegal trade.

In fact, they found illegal market was flourishing and became open domestic markets in Sumatra. They sold body parts of tigers.

The hunt for commercial purposes and loss of habitat are the main concern of the tiger’s life. The tigers was shot or poisoned cause considered as pests and for earn money. Hunters aimed skin and flesh of tigers. However, Main factor of hunters are the high prices of tiger skin. It causes the reduce of Sumatran tigers.

Sumatran tigers has a bone which contain high nutrition. Therefore, China and Korea uses their bone as traditional medicine. However, It has a big impacts to habitat of the tigers. It loss rapidly due to growth and the spread of human population. So, tiger population increasingly isolated in a few small areas.

In 2013, There are six to eight Sumatran tigers who live in Sumatra. Meanwhile, in early 2017, It detects only couples of tigers who still exists. However, for three years, there are 58 of Sumatran tigers was trade.

There are threats of Sumatran tigers existence, such as:

A. Conflict between Human and Tigers

Human-tiger conflict has conducted since early seventies. At that time, it was a high population growth along with economic led the increased of land use. Conversion of forest lands for human needs became unavoidable. Then loss of their natural habitat raises a potential conflict between human and tiger.

Based on information, Between 1978 to 1997, There were 146 people died and 30 people injured. Meanwhile, in 1995 to 2008, Sumatra island has recorded at least 100 conflicts occurred.

B. The Hunting

Sumatran tiger hunting activity still ongoing until now. Despite there are a prohibition for the hunters will be resolute sanctions and penalties. However, the high interest to trade each part of tiger’s body makes hunting tigers still difficult to overcomes. The government should be able to apply tough sanctions against the hunter.

The economy factors become main reason people trade Sumatran tigers. Even lately, in Cyberspace area, there are companies or person which advertise each part of tiger’s body with complete prices.

C. Deforestation and Degradation

The huge deforestation and degradation indirectly posed a threat to biodiversity. It will lead the loss of forest or break into small parts of forests. Agriculture, mining, expansion, and transmigration. Those are threat.

D. The Hunt of the Prey

the main food in the forest constantly decreasing in several years. Deer, Pigs, monkeys, are the main prey of tiger becomes the target for hunting. Poachers often enter conservation area and other forest area. It is the biggest threat to the conservation of protected animals.

The Efforts of Sumatran Tiger Conservation

There are several efforts for Sumatran tiger conservation, both from government and WWF.

  • Government

Trading tiger parts in Indonesia is a criminal offense for violating Law No. 5 of 1990 on Conservation of Natural Resources and Ecosystems. Every person is prohibited to trade, store, or possess parts of protected animals. It includes law of make a goods from the parts of these animals or removing into other places in Indonesia.

Violators of these provisions may be subject to criminal in the form of a maximum of five years imprisonment and fine up to 100 million.

The preserve of tiger existence through Sumatran tiger conservation is not merely aim only for the tiger. It also protects the other species because between them are interconnected. So in other words, to protect this species indirectly protect other animals.

Several attempts to maintain the sustainability of the Sumatran tiger are as follows:

  1. Restoring and increase the population of tigers and their landscapes. In-situ conservation effort is the main program Sumatran tiger conservation by restoring populations of tigers and their natural habitats.
  2. Improving the infrastructure and the capacity of relevant agencies. It monitoring and evaluation the conservation of the Sumatran tiger and its prey species.
  3. Build networking and communications infrastructure. It creates a caring community groups and responsible for the conservation of Sumatran tigers. Sumatran tiger conservation is the responsibility of all parties. Therefore, it should be enlisted in networking and good communication among all parties.
  4. Build ex-situ conservation programs that are beneficial in harmony with the Sumatran tiger conservation . Especially efforts in the wild life of Sumatran tigers. Ex-situ conservation is one alternative for conserving tigers. However, the necessary regulations government standards need to be formulated ex-situ conservation to complete ethical standards and welfare for the Sumatran tiger.
  5. Protect intensively habitats of Sumatran tiger which lives in conservation areas.
  6. Expand conservation area that serves as a habitat for the Sumatran tiger. It extents to accommodate the tiger population in conditions of healthy and independent.
  7. Integrated management on the Sumatran tiger habitat contained in the outer conservation areas. Therefore, the exploitation of natural resources for economic and conservation interests can work well.
  8. Protect Sumatran tiger habitat in areas used as a plantation. It important areas for tigers without reducing and inhibiting the production goals of forest.
  9. Development tiger protection unit consisting of forest police. It intensively patrolling the protection of tigers, prey and habitat.
  10. Keep monitoring of Sumatran tiger population and its prey in the long term.
  11. Develop the arrangement of distribution and translocation. In case if ecological aspect has not been possible to implement.

Humans are given the responsibility for keeping the earth. Then They should care for the earth and utilize the existing natural resources as well as possible and a full sense of responsibility. Sumatran tiger conservation can not be separated from human action irresponsible.

Therefore, conservation efforts must remaining consistent. However, most importantly is the support of all stakeholders. They help the implementation of conservation. So the existence of tigers as a species endemic to the island of Sumatra is maintained continuity.

  • WWF (Worldwide Fund)

WWF Indonesia in cooperation with the Government of Indonesia. It takes concern of threaten tiger habitat industry. Along with conservation organizations and local communities to save Sumatran tigers from extinction.

 In 2004, the Indonesian government declared the region an important, Tesso Nilo, a National Park to ensure a secure future for the existence of the Sumatran Tiger. In 2010, the Tiger Summit in St. Petersburg, Indonesia and 12 other countries that protect tigers committed to an ambitious goal of species conservation.

Meanwhile, WWF is currently conducting groundbreaking research on Sumatran tigers in Central Sumatra. It using camera traps to estimate population numbers, habitat and distribution to identify wildlife corridors in need of protection. Then, WWF also fielded anti-poaching patrols and units that work to reduce human-tiger conflict in local communities.

The Ethical of Meeting Endangered Animal

There are rural communities live close to the forests. They are collect forest goods and sometimes meet the tigers. tiger is animal which never bother humans. Nevertheless, there have been several time while tigers interfere and targeting human as their prey. It caused by some cases.
