Dehing Patkai National Park - Assam’s Hidden Rainforest & Wildlife Haven

Dehing Patkai National Park, often called the “Amazon of the East,” is one of India’s most vibrant and biologically rich rainforests. Spread across the Dibrugarh and Tinsukia districts of Assam, this park forms a vital part of the Dehing-Patkai Elephant Reserve — a landscape where ancient trees, mist-laden canopies, and the calls of hornbills fill the air.

Declared a National Park in 2021, Dehing Patkai represents one of the last remaining stretches of lowland tropical rainforest in India. Its dense green cover shelters an extraordinary variety of wildlife, including elephants, clouded leopards, and over 300 species of birds. The park is also home to rare orchids, wild bananas, and Assam’s state tree, the Hollong, which towers high above the forest floor.

Beyond its natural grandeur, Dehing Patkai carries deep cultural and historical significance. This region has witnessed centuries of tea cultivation, oil exploration, and coal mining — industries that shaped Assam’s identity while also challenging its delicate ecosystem. Today, it stands as a symbol of resilience and conservation, reminding us of the urgent need to protect what remains of India’s rainforests.

For travellers, Dehing Patkai offers a glimpse into a world where nature reigns supreme — a realm of lush greenery, whispering streams, and the rhythmic pulse of wild Assam.

Location and Geography

Where Dehing Patkai Lies

Dehing Patkai National Park spreads across the Dibrugarh and Tinsukia districts of upper Assam, forming part of the larger Dehing-Patkai Elephant Reserve. It covers an area of about 234 square kilometers, making it one of the richest biodiversity zones in Northeast India. The park is around 80 kilometers from Dibrugarh, a major city known for its tea gardens and airport connectivity.

A Landscape of Evergreen Majesty

This rainforest thrives in the foothills of the Patkai Range, which forms a natural border between India and Myanmar. The terrain is mostly low-lying and undulating, carpeted with dense tropical evergreen and semi-evergreen forests. The Dehing River, from which the park gets its name, flows gracefully through these woods, feeding countless streams and wetlands that sustain life here.

Climate and Environment

Dehing Patkai experiences a humid tropical climate with heavy rainfall, especially between May and September. The abundant rain nourishes the dense canopy and undergrowth, supporting an incredible range of flora and fauna. Mist often hangs in the early mornings, adding a mystical aura to the forest — a paradise for photographers and nature lovers alike.

A Vital Ecological Corridor

The park forms an essential corridor connecting the forests of Assam with those of Arunachal Pradesh and Myanmar, allowing animals like elephants and big cats to move freely. This connectivity makes Dehing Patkai a cornerstone for regional conservation and one of the last intact rainforests in the Brahmaputra Valley.hape each other’s stories.

History and Conservation Status

From Forest Sanctuary to National Park

Before earning its national park status, Dehing Patkai was part of the Dehing Patkai Wildlife Sanctuary, established in 2004. This sanctuary, spread across Dibrugarh and Tinsukia districts, was known for its thick rainforest cover and its role as a vital elephant habitat. After years of public awareness campaigns and conservation movements, the Assam government declared Dehing Patkai a National Park in June 2021, recognizing its ecological importance and the urgent need to protect its fragile ecosystem.

A Legacy of Coal and Oil

The region surrounding Dehing Patkai holds deep historical roots in Assam’s industrial story. It was here that India’s first oil well was drilled in Digboi, and coal mining began in the late 19th century under British rule. While these industries shaped Assam’s economy, they also left scars on the land, causing habitat loss and fragmentation. The forest has long been at the crossroads of progress and preservation.

The Turning Point – Public Uprising for Nature

In 2020, reports of renewed coal mining activities within the forest sparked widespread concern. Environmentalists, students, and local communities rallied together under the “Save Dehing Patkai” movement, demanding strict protection for the rainforest. The outcry gained nationwide attention, becoming one of India’s strongest modern conservation movements. It ultimately pushed the government to elevate the sanctuary’s status, ensuring greater legal protection.

Current Conservation Efforts

Today, the park is managed under the Assam Forest Department, with efforts focused on habitat restoration, anti-poaching patrols, and regulating human activity around its borders. NGOs and research institutions are working on biodiversity surveys, elephant corridor mapping, and community-based conservation initiatives to promote harmony between people and wildlife.

A Living Symbol of Hope

Dehing Patkai stands as a living testament to what collective action can achieve. Its journey from an exploited resource zone to a protected rainforest reflects India’s growing awareness of environmental balance. Every rustle of leaves and echoing birdcall here reminds visitors that nature, when defended, has the power to heal and thrive again.
