The Majestic Bengal Tiger: Conservation Success in the Sundarbans

The Sundarbans, the world’s largest mangrove forest, straddling the border of Bangladesh and India, is a vital stronghold for the Bengal tiger (Panthera tigris tigris). In a really engaging interview with the UNB digital team on August 4, 2025, Prof. Dr. Md. Anwarul Islam, the CEO of Wildteam, gave some eye-opening updates about the tigers living in this incredible place and other areas, sharing stories of conservation triumphs and a bit of historical context.

Rising Tiger Numbers in the Bangladesh Sundarbans

Recent surveys indicate a promising upward trend in the tiger population within the Bangladesh portion of the Sundarbans. According to Prof Islam, the Forest Department recorded 106 tigers in 2015 using camera trapping techniques. By 2018, a collaborative effort between the Forest Department and Wildteam counted 114 tigers. The most recent survey in 2024, conducted by the Forest Department, reported 125 adult tigers, reflecting a nearly 10% increase since 2018 and a 17.92% rise since 2015. This growth is attributed to enhanced conservation measures, including anti-poaching patrols and habitat protection initiatives.

The Sundarbans ecosystem is divided between Bangladesh and India, with approximately 60% of the forest located in Bangladesh and 40% in India. Prof Islam noted that while Bangladesh hosts 125 tigers, the Indian Sundarbans is estimated to have around 100 tigers, based on the latest available data from 2022. This brings the total tiger population in the Sundarbans to an estimated 225-250. The mangrove forest, a UNESCO World Heritage Site, is the only mangrove habitat in the world inhabited by tigers, making it a critical conservation area.

Region Estimated Tiger Count Percentage of Sundarbans Area
Bangladesh 125 (2024) 60%
India 100 (2022) 40%
Total 225-250 100%

 

Global Tiger Population and India’s Role

According to Prof. Islam, Globally, the tiger population is estimated at approximately 5,500, with India accounting for about 70% of this total, or roughly 3,850 tigers. According to a 2022 census, India’s tiger population stood at 3,682, with key reserves like Jim Corbett (260 tigers), Bandipur (150), and the Sundarbans (100) contributing significantly. This dominance underscores India’s pivotal role in global tiger conservation, supported by initiatives like Project Tiger and the expansion of tiger reserves.

Historical Presence of Tigers in Bangladesh

Prof Islam reflected on the historical distribution of tigers in Bangladesh, noting that they once roamed freely in regions such as Gazipur, Sylhet, Modhupur, and other areas. However, habitat loss, deforestation, and human encroachment have restricted their range to the Sundarbans. He cited an example of a tiger killed in Gazipur approximately 100 years ago, illustrating the significant contraction of tiger habitats over time. Today, the Sundarbans remains the last refuge for tigers in Bangladesh, emphasizing the need to protect this critical ecosystem.

Clarifying the Royal Bengal Tiger

A common misconception is that the "Royal Bengal tiger" is a distinct subspecies. Prof Islam clarified that the term refers to the habitat rather than a unique taxonomic classification. The Bengal tiger (Panthera tigris tigris) is found across Bangladesh, India, Myanmar, Nepal, and Bhutan, thriving in diverse environments from mangrove swamps to deciduous forests. The Sundarbans’ tigers are morphologically distinct due to their adaptation to the mangrove habitat, but they are part of the broader Bengal tiger population.

Tiger Subspecies and Habitat Loss

Historically, there were nine recognized tiger subspecies, but only six remain today due to extinction events over the past century. These include:

Bengal tiger (Panthera tigris tigris): Found in India, Bangladesh, Nepal, Bhutan, and Myanmar.
Indochinese tiger (Panthera tigris corbetti): Inhabits Cambodia, Laos, Myanmar, Thailand, and Vietnam.
Malayan tiger (Panthera tigris jacksoni): Found in peninsular Malaysia.
Siberian tiger (Panthera tigris altaica): Resides in the Russian Far East and parts of China.
Sumatran tiger (Panthera tigris sondaica): Found only on the Indonesian island of Sumatra.
South China tiger (Panthera tigris amoyensis): Functionally extinct in the wild, with small populations in captivity. 

Prof. Islam’s words stayed with me. The Sundarbans’ 125 tigers in Bangladesh are a sign of hope, thanks to years of hard work. But the fight isn’t over. We need to keep protecting this forest. The Bengal tiger, with its quiet strength, depends on the Sundarbans and on us. This interview reminded me why we can’t look away from this fight to save a piece of our wild heritage.
