Tiger Panthera tigris

Tiger Panthera tigris

Endangered

Population: Around 3,900

Extant (resident): India, Bangladesh, Bhutan, Nepal, Myanmar, Malaysia, Indonesia, Thailand, China, Russia

Tigers, primarily native to Asia’s tropical forests, have seen their habitats shrink dramatically over time. Notably, the Amur Tiger endures in Russia, and there have been sightings of these majestic creatures as high as 4,500 m in Bhutan. Tragically, fewer than 400 tigers remain in Indonesia, clinging to life in Sumatra’s dwindling forests. This decline is attributed to both rampant poaching and severe deforestation, especially for palm oil and pulp industries. As Asia continues to develop rapidly, the vast territories tigers need are shrinking, replaced by agriculture, commercial logging, and settlements. Moreover, tigers‘ prey faces threats from hunting and competition with domestic livestock. It’s time to act and use our wallet as a weapon: be #vegan #Boycottpalmoil #Boycott4Wildlife.

Tigers, the largest members of the cat family, are renowned for their majestic presence and striking orange coats with black stripes. They possess extraordinary strength and agility and maintain the balance of ecosystems as apex predators. With fewer than 4,500 remaining in the wild, tigers are classified as Endangered, facing grave threats from habitat destruction for palm oil, poaching, and human-wildlife conflict.

Their survival depends on urgent protection and animal advocacy. Protecting tigers ensures the preservation of the rich biodiversity within their habitats. Support their future by joining the #BoycottPalmOil and #Boycott4Wildlife movements.

Habitat

Tigers inhabit a wide variety of environments, including tropical rainforests, mangrove swamps, grasslands, and boreal forests. They require vast territories to hunt and breed, with males typically occupying larger ranges than females. Tigers are currently found in fragmented populations across Asia, with key strongholds in India, Sumatra, and Siberia.

These habitats are increasingly under threat due to deforestation, agricultural expansion, and infrastructure development, which have reduced their historical range by over 93%.

Diet

As apex predators, tigers primarily hunt large prey, such as sambar deer, wild boar, and buffalo. They are known for their stealth and strength, often ambushing their prey with a single powerful strike. Unlike other big cats, tigers can swim to catch prey, a unique skill that sets them apart.

In areas with reduced prey availability, tigers may hunt smaller mammals or livestock, which can lead to conflicts with humans.

Appearance and Behaviour

Swimming Ability: Tigers are strong swimmers, often crossing rivers and lakes to hunt or cool off—an unusual trait among big cats.

Individualised Stripes: Their stripes serve as camouflage and are unique to each tiger, making them distinguishable even in dense foliage.

Vocal Range: Tigers have a wide vocal range, including growls, roars, and chuffs, used to communicate with other tigers.

Apex Predator Status: As the top predator in their ecosystems, tigers help maintain balance by regulating prey populations.

Tigers are uniquely recognisable by their bold stripe patterns, which are as individual as fingerprints. Their muscular builds, powerful limbs, and retractable claws make them adept hunters and swimmers, setting them apart from most other big cats. Unlike lions or cheetahs, tigers are solitary by nature and fiercely territorial.

Their physical features include a robust skull, long canine teeth, and strong jaw muscles designed for gripping and tearing prey. Tigers are also among the few big cats that enjoy water, often cooling off in rivers and lakes. Their signature behaviours include scent marking, vocalisations such as roars and chuffs, and stealthy stalking of prey.

Reproduction & Mating

Tigers reach sexual maturity at around 3-4 years of age. Breeding typically occurs year-round, but more frequently during the winter months. After a gestation period of approximately 100 days, females give birth to 2-4 cubs in secluded dens.

Cubs are dependent on their mothers for the first 18 months, learning essential survival skills like hunting. Only about half of all cubs survive to adulthood, as they face threats from predators, disease, and starvation.

Threats

Habitat Destruction: Deforestation for palm oil agriculture, timber logging, and development fragments their habitats, isolating populations.

Poaching: Tigers are hunted for their skins, bones, and other body parts, often sold illegally for traditional medicine or as luxury items. Organisations like EIA directly combat this illegal trade.

Prey Depletion: Overhunting of herbivores reduces food availability, impacting tiger populations.

Human-Wildlife Conflict: As human settlements expand, conflicts arise, often leading to retaliation killings of tigers.

The last of Indonesia’s tigers—now fewer than 400—are holding on for survival in the remaining patches of forests on the island of Sumatra. While poaching claims most tigers each year, deforestation remains a serious threat.

Sumatra has lost more than half of its forests in the last 40 years, primarily due to conversion for palm oil and pulp plantations. Poaching for illegal trade in high-value Tiger products including skins, bones, meat and tonics is a primary threat to Tigers.

Asia is a densely populated and rapidly developing region, bringing huge pressures to bear on the large wild areas required for viable Tiger populations. Conversion of forest land to agriculture and silviculture, commercial logging, and human settlement are the main drivers of Tiger habitat loss. With their substantial dietary requirements,

Tigers require a healthy large ungulate prey base, but these species are also under heavy human subsistence hunting pressure and competition from domestic livestock.

Tigers are classified as Endangered on the IUCN Red List, with fewer than 4,500 individuals remaining in the wild. While conservation efforts have stabilised some populations, habitat loss and poaching continue to pose significant challenges. Collaborative international efforts are crucial to ensuring their survival.

The last of Indonesia’s tigers—now fewer than 400—are holding on for survival in the remaining patches of forests on the island of Sumatra. While poaching claims most tigers each year, deforestation remains a serious threat.

Tiger by Dalida Innes Wildlife Photography

The year 2023 coincided with the 50th anniversary of India’s groundbreaking Project Tiger, an innovative programme designed to rescue the country’s iconic big cat from the precipice of extinction. In April, as part of these celebrations, prime minister Narendra Modi announced that tiger numbers in India have now surpassed 3,000, representing more than 70% of the wild tigers in the world.

From an initial investment in 1973 of just nine dedicated tiger reserves, India now protects 54 such areas. It adds up to an area in excess of 75,000 sq kilometres, or about 2% of the country.

Now, new research in the journal Nature Ecology and Evolution has identified a link between tiger conservation and the fight against climate change. Tigers are very adaptable and the exact same subspecies, the Bengal tiger, can be found scattered across India in jungles, mangroves and so-called “dry forests”. These habitats might seem very different, but the common link is of course lots of trees.

According to the authors of the new study, the strict protection provided within India’s network of tiger reserves has avoided huge amounts of deforestation. And by preserving forests that would have otherwise been chopped down, between 2007 and 2020, tiger protection may have contributed to over 1 million tonnes of avoided carbon emissions.

A million tonnes of carbon might sound like a lot, though it won’t put a huge dent in climate change. India alone emits about 2.7 billion tonnes each year (albeit very little per capita). But that isn’t the point.

In a monetary sense, that avoided deforestation and saved carbon can be equated to US$6.24 million (£5.06 million) in direct carbon offsets and, if wider “ecosystem services” such as watershed management and the provision of fuel and firewood are considered, this figure could rise to as much as US$92 million (£75m). The authors of the new research suggest that this could be a gamechanger for tiger protection, as it could be funded through carbon offset schemes.

There are critics who view India expanding its tiger reserves as an economic extravagance, one that brings the animals into conflict with humans and criminalises local communities (some of whom have been moved out of reserves) for living as they have always done. But in a neoliberal world where everything has a price tag, the future of vulnerable wildlife often depends on its ability to justify its own survival. And if carbon storage can be added to the list of reasons to protect tiger habitat, this in turn may provide fresh impetus for conservation.

Still lots of habitat left

Even after centuries of deforestation and an expansion of farmland to feed a billion people, there still seems to be land available. In a recent interview in The Hindu newspaper the prominent tiger biologist Ullas Karanth made it clear that India has the potential, on paper at least, to quadruple its wild tiger numbers over the longer term. According to Karanth, there is still an estimated 380,000 sq kilometres of potential habitat available, just 20% of which is currently under strict protection and containing tigers.

The loss of their forests is still the main reason why tigers are threatened. But this meant there are habitats available that have been emptied of tigers by hunting, and which cannot be colonised by new populations since there are no safe “wildlife corridors” connecting one patch of forest to another.

If these vacant forests were given their proper value and managed with both (reintroduced) big cats and the climate in mind, India could further cement its position as the world leader in tiger conservation. Eventually it could start exporting surplus tigers to repopulate sites in neighbouring countries where Bengal tigers have declined (the many tigers in captivity, especially in the US, are too used to humans to be released into the wild).

This is a win-win situation. It would also help India to re-establish its green credentials during an era in which the country’s emphasis on development and business has conflicted with parallel efforts to protect its natural environment.

The Sumatran tiger Panthera tigris sumatrae is teetering on the brink of extinction. Recent findings underscore the urgency of protecting the last remaining populations of these unique and majestic apex predators. With deforestation continuing at alarming rates to meet global demands, particularly for palm oil, these tigers face severe threats to their survival. Another serious threat to their dwindling number is poaching. This article examines the findings of recent studies and argues for stricter forest protection regulations, enforcement of the European Union Deforestation Regulation (EUDR), and consumer boycotts of palm oil will help to protect Sumatra’s rainforests and wild animals.

Sumatran Tigers in Serious Trouble

The Sumatran tiger, the most diminutive subspecies of tiger in the world, is now restricted to the Indonesian island of Sumatra. Once widespread, these tigers have lost more than 70% of their habitat due to extensive logging, the expansion of palm oil monoculture, and poaching (Figel et al., 2024). A recent study by Figel and colleagues revealed that in the Ulu Masen Ecosystem, only 11 tigers were detected during a monitoring period from 2020 to 2022, with a male-biased ratio of eight males to one female, indicating significant population stress from poaching pressures and habitat loss (Costa, 2024). Without immediate and intensive action, these tigers face the same fate as the now-extinct Javan and Balinese tigers.

Habitat Loss and Deforestation: The Palm Oil Crisis

Forests critical to tiger survival are rapidly disappearing, largely driven by deforestation for palm oil, timber and mining. According to a study published in Scientific Reports, deforestation has been particularly damaging to lowland and primary forests, essential habitats for Sumatran tigers (Smith et al., 2018).

Palm oil companies in Indonesia, the world’s top producer of the commodity, cleared 30,000 hectares (about 74,100 acres) of forest last year to make way for plantations, up from 22,000 hectares (54,400 acres) in 2022 (Mongabay, 2024).

Over decades, rainforest loss for palm oil and timber on the island of Sumatra along with poaching of tigers has resulted in severely isolated tiger populations and loss of genetic diversity, which further compounds the risk of extinction (Wibisono, 2024). Despite legal protections, these animals are often displaced as logging companies encroach upon their habitats.

Strict Global Laws Needed to Protect Tigers and Rainforests

The European Union has recognised this issue through the European Union Deforestation Regulation (EUDR), which mandates that companies importing into the EU must prove that their products containing palm oil are not linked to deforestation. Although promising, the enforcement of the EUDR will be crucial for real impact, especially in countries like Indonesia, where lax regulation and government corruption has allowed large-scale deforestation to flourish (Figel et al., 2024).

Urgent Anti-Poaching Protection Needed

Poaching has been another devastating factor for Sumatran tigers, as highlighted by Figel et al. (2024). In their recent camera-trap study, they found alarming signs of tiger limb injuries due to snares, an indication of pervasive illegal hunting. In comparison to other tiger habitats in Sumatra, the lack of female tigers and cubs in the Ulu Masen region shows a population under severe stress. This study calls for the immediate introduction of up to 600 trained rangers to combat poaching and support tiger conservation in Ulu Masen—a recommendation that reflects the success of similar efforts in Kerinci-Seblat National Park, where a 41% reduction in snares was achieved through a well-resourced ranger network (Costa, 2024).

Protecting Prey and Preserving Balance in Ulu Masen

The Figel study underscores that the survival of Sumatran tigers in Ulu Masen hinges on reducing poaching and preserving prey populations, such as sambar deer, which play a critical role in tiger sustenance. Despite Ulu Masen’s extensive forest cover, the lack of formal protection leaves tigers vulnerable to habitat loss, illegal logging, and rampant snare usage, which remains the leading threat. With only one female observed among 11 tigers, the population skew suggests severe poaching pressures, underscoring the need for robust, targeted protection. Implementing a larger ranger network, akin to successful efforts in other Indonesian parks, is essential for tackling these threats and ensuring that Ulu Masen remains a viable habitat for Sumatran tigers.

Consumer Awareness and the Call to Boycott Palm Oil

To effectively protect these remaining tigers, consumer awareness and strong consumer action is equally important. By boycotting palm oil in the supermarket and supporting alternative vegan palm oil free products, consumers can reduce demand for this resource, which remains a primary driver of deforestation in Sumatra (Luskin et al., 2017). Educating consumers about the environmental costs associated with palm oil and meat deforestation is crucial; with heightened awareness, individuals can contribute to conservation efforts by opting for palm oil free alternatives.

We May Still Have Time to Secure Their Future

The plight of the Sumatran tiger reveals the interconnectedness of conservation, international environmental laws and consumer boycotts. While regulations like the EUDR are necessary, their strict enforcement is essential to prevent further destruction of tiger habitats. Alongside this, consumer action in the form of boycotting palm oil can make a meaningful difference. Protecting Sumatra’s forests is not just about saving a single species; it is about preserving an entire ecosystem under siege from the scourge of palm oil monoculture. By taking strong collective action, we still have time to secure a future for the Sumatran tiger and countless other species that depend on rainforests.

Sumatran Tiger Panthera tigris sondaica

Sumatran tiger Panthera tigris sondaica

Critically Endangered

Extant (resident): Sumatra, Indonesia

The Sumatran tiger Panthera tigris sondaica is a critically endangered big cat, with less than 600 of their species alive in the wild today. Once living in Java and Bali, they are now only found in Sumatra, Indonesia. The smallest tiger species, they possess darker coats and narrower stripes than their mainland counterparts. Each pattern is as unique and distinct as a fingerprint. Sumatran Tigers face serious and grave threats from palm oil habitat destruction, poaching, and human-wildlife conflict. Sumatra’s ongoing deforestation, driven by palm oil and acacia plantations, continues to shrink their habitat. While illegal poaching for the wildlife trade is decimating their population. Conservation efforts are underway, but the future of this magnificent species hangs in the balance. You can help protect the Sumatran tiger every time you shop. Learn how to boycott palm oil on the Palm Oil Detectives website. Raise awareness of them on social media using the hashtags #BoycottPalmOil #Boycott4Wildlife.

Appearance & Behaviour

  • Their distinctive stripes are unique to each individual, similar to human fingerprints.
  • They are strong swimmers, often moving between islands and across rivers in order to seek new territory or hunt prey.

Sumatran tigers possess a rare combination of strength, beauty, and mystery that has captivated the human imagination since time immemorial. Their deep orange coats with distinctive black stripes seem to ripple as they move stealthily through dense forests. Unlike their mainland cousins, their coats are darker, and their stripes dissolve into spots, making them even more unique. Tigers in Sumatra are known for their grace and ferocity, moving silently through their home territory, often evoking admiration, fear and awe in all other species.

They are the smallest subspecies of tiger. Males weigh between 100-140 kg and females between 75-110 kg. Their compact size, compared to other tiger species, helps them move with agility through the dense forests of Sumatra.

These tigers like many other big cats prefer deep forests where they can blend into the foliage. Solitary creatures, Sumatran tigers only coming together for mating or a mother raising her young. These tigers are fiercely protective of their territory and will patrol vast areas to ensure their dominance. Their elusive and cryptic nature, combined with their regal appearance, inspires deep reverence from those who witness them.

Threats

Palm oil and timber deforestation

Clearing of forests for palm oil plantations and illegal logging for timber continues to destroy the Sumatran tigers’ natural habitat. Between 1985 and 2014, forest cover on Sumatra was reduced from 58% to just 26%. Forest destruction isolates tiger populations, making it difficult for them to hunt, breed, and thrive.

Illegal poaching and black market trade in body parts

Tigers are killed for their skins, bones, and teeth, which are highly valued in traditional medicine and as luxury items. This illegal trade continues despite intensified conservation efforts, leading to significant population declines.

Human-Tiger Conflict

As tigers lose their forest homes, they move closer to human settlements, sometimes attacking livestock. Retaliatory killings by villagers and farmers on palm oil plantations often result in the death of tigers, further reducing their numbers.

Genetic Conditions from Captive Breeding

Tigers captured from the wild and then bred in Zoos face genetic disorders due to inbreeding, such as vestibular dysfunctions. Vestibular dysfunctions include: head tilt, circling, ataxia (loss of muscle control), strabismus (being cross-eyed) and nystagmus (rapid uncontrolled movements of the eyes). A 2015 study observed these signs observed between birth and 2 months of age. These conditions can affect their health and ability to thrive and reproduce.

Habitat

Sumatran tigers inhabit a wide variety of forest habitats, including lowland tropical forests, hill forests, and montane forests. They are known to live in areas from sea level up to elevations of 3,200 metres in the highlands of Gunung Leuser National Park. Although they prefer dense forest areas for cover, Sumatran tigers are also forced to enter human-dominated landscapes such as farms and monoculture plantations at the edges of protected areas. Habitat fragmentation mainly occurs due to palm oil deforestation. These areas are less ideal for tigers and increase the likelihood of human-tiger conflicts. Sumatran tigers require large, contiguous forest blocks to roam, breed, and hunt effectively.

Diet

Sumatran tigers are apex predators, feeding primarily on medium to large-sized mammals. Their diet consists of wild pigs, sambar deer, Malayan tapirs, and occasionally monkeys and birds. Tigers rely on stealth and ambush tactics to catch their prey, stalking their target before launching a powerful and precise attack. In some areas, prey depletion has forced tigers to rely more on smaller animals or venture closer to human settlements, which increases the risks of conflict with humans. Their role as top predators is crucial in maintaining the balance of their ecosystem by controlling prey populations. This prevents overgrazing and helps to preserve forest vegetation.

Mating and breeding

Sumatran tigers are solitary animals that come together only for mating. Females typically give birth to litters of two or three cubs after a gestation period of about 3.5 months. Cubs are born blind and helpless, relying on their mother for protection and food for up to two years. During this time, the mother teaches the cubs essential hunting skills. Tigers reach sexual maturity at around 3 to 4 years of age. Due to their territorial nature, males will fight to defend their territory from other males, and only the strongest males have the opportunity to mate.

Conservation

Several organisations are working to protect the Sumatran tiger, including Fauna & Flora International, Panthera, and TRAFFIC.
