Wild tigers live in 13 countries across Asia, from the frozen forests of eastern Russia to the tropical mangrove swamps of India and Bangladesh. Their current range is a fraction of what it once was. Over the past century, tigers have lost more than 93% of their historic territory. Today, an estimated 5,574 wild tigers survive in scattered populations, up from an all-time low of roughly 3,200 in 2010.
India: The World’s Tiger Stronghold
India is home to the majority of the world’s wild tigers. Bengal tigers, the most abundant subspecies, occupy a variety of landscapes across the country, from subtropical forests and grasslands to the famous Sundarbans, a vast mangrove delta shared with Bangladesh. The Sundarbans is one of the most unusual tiger habitats on Earth: a maze of tidal flats, swamps, and dense scrub vegetation where tigers swim between islands and hunt in knee-deep water.
Beyond the Sundarbans, India’s tiger populations are spread across dozens of designated tiger reserves. States like Madhya Pradesh, Karnataka, Uttarakhand, and Rajasthan all contain significant populations. India’s commitment to tiger conservation has been a major driver behind the global population rebound over the past decade.
Nepal, Bhutan, and Bangladesh
Nepal shares tiger habitat with India along its southern lowlands, particularly in protected areas like Chitwan and Bardia national parks. Nepal has been one of the notable success stories in tiger conservation, with its population growing steadily in recent years. Bhutan supports a smaller population in its subtropical forests along the Indian border. Bangladesh’s tigers are concentrated almost entirely in its portion of the Sundarbans mangrove forest.
Southeast Asia’s Last Strongholds
Indochinese tigers once ranged across mainland Southeast Asia, but their populations have contracted dramatically. Thailand now serves as the subspecies’ last real stronghold, with an estimated 220 individuals. About 95% of Thailand’s tigers live in just two forest complexes: the Western Forest Complex, a network of 17 protected areas spanning roughly 19,000 square kilometers along the Myanmar border, and the Dong Phayayen-Khao Yai forest complex in eastern Thailand, which supports around 20 individuals across five protected areas.
The Western Forest Complex, with 152 to 196 tigers, holds the largest tiger population outside of South Asia. Myanmar likely still has a small breeding population, but its status remains uncertain. Cambodia and Vietnam are listed as tiger range countries, though confirmed sightings have become extremely rare, and some conservationists consider tigers functionally absent from much of their former range in these countries. Laos faces a similar situation.
Russia’s Far East
The Amur tiger (commonly called the Siberian tiger) lives in the temperate and boreal forests of Russia’s Far East, specifically in Primorski Krai and southern Khabarovski Krai. This is the northernmost tiger population in the world, adapted to harsh winters, deep snow, and vast stretches of forest. Amur tigers range across a much larger territory per individual than their tropical counterparts, partly because prey density is lower in cold climates.
A small number of Amur tigers also cross into northeastern China, primarily in eastern Jilin Province and eastern Heilongjiang Province. China has invested heavily in creating a national park system along this border region to support tiger recovery, and camera traps have confirmed tigers moving back and forth between the two countries.
Sumatra: The Only Island Population
The Sumatran tiger is the sole surviving island subspecies, found only on the Indonesian island of Sumatra. It is critically endangered. Key populations persist in Kerinci Seblat National Park in South Sumatra, Berbak National Park on the east coast, and the Dangku conservation area. These tigers inhabit tropical rainforest and peat swamp forest, both of which face ongoing pressure from logging and palm oil plantations.
Sumatran tigers are notably smaller than their mainland relatives, an adaptation to island life. Their survival depends heavily on anti-poaching patrols. Conservation efforts in Kerinci Seblat have reduced active tiger snares in the park’s core area by 85%.
Malaysia’s Shrinking Rainforests
The Malayan tiger lives on the southern Malay Peninsula, relying on dense rainforest canopy and riverine thickets. Malaysia’s tiger population has declined sharply in recent decades due to habitat loss and poaching, and the subspecies is now critically endangered. Most remaining individuals are found in the forested interior of Peninsular Malaysia, particularly in and around Taman Negara National Park and the Belum-Temengor forest complex.
One Subspecies Already Gone From the Wild
The South China tiger is considered functionally extinct in the wild. No confirmed sightings have occurred in decades, and the subspecies survives only in captive breeding programs. China was historically one of the tiger’s major range countries, but hunting and habitat destruction through the mid-20th century eliminated the South China population. The Amur tigers in China’s northeast are a different subspecies entirely.
Habitats Tigers Use
Tigers are more adaptable than most people assume. They are not strictly jungle animals. Wild tigers occupy tropical rainforests, temperate hardwood forests, mangrove swamps, grasslands, and even the cold coniferous forests of Siberia. What they consistently need is dense cover for stalking prey, access to water, and sufficient large prey animals like deer, wild boar, or water buffalo.
Elevation is not a barrier either. Some tiger populations in the Himalayas and the highlands of Southeast Asia live in montane forests well above 2,000 meters. The common thread across all tiger habitat is not a specific biome but a combination of cover, prey, and protection from human disturbance. Where those three factors align, tigers can persist in remarkably different environments.
