Dibru-Saikhowa National Park

– A Complete Travel Guide to Assam’s Riverine Wilderness

Dibru-Saikhowa National Park, located in the Dibrugarh and Tinsukia districts of Upper Assam, is one of India’s most fascinating riverine protected areas. Designated both as a National Park and a Biosphere Reserve, it lies amidst the dynamic floodplains formed by the Brahmaputra, Lohit and Dibru rivers. This unique confluence of mighty waterways has created a landscape of swamps, river islands, grasslands, scrub forests and patches of semi-evergreen woodland that together support an extraordinary level of biodiversity. Recognised as one of the important biodiversity hotspots in the region, Dibru-Saikhowa is especially famous for its feral horses, rare birds, wetland ecosystems and tranquil scenery.

The park covers a core area of about 340–350 sq km within a larger biosphere reserve of around 765 sq km, making it one of the largest swamp forest ecosystems in Northeast India. According to Dibru-Saikhowa National Park on Wikipedia, the site was declared a Biosphere Reserve in 1997 and a National Park in 1999, following a conservation history that began with reserved forest notifications in the late 19th and early 20th centuries. Today, Dibru-Saikhowa is valued as a refuge for several endangered species as well as a living laboratory for ecological studies on floodplain dynamics.

Government-authenticated information about Dibru-Saikhowa’s basic profile, climate and habitats can be found on the official tourism portal Assam Tourism – Dibru-Saikhowa National Park, which describes it as a semi-wet evergreen, moist deciduous, bamboo and grassland mosaic, still retaining much of its untouched character.

Geographical Setting and Landscape Character

Dibru-Saikhowa lies in the extreme east of Assam, in a region where several Himalayan rivers converge with the Brahmaputra. The park is bounded by the Brahmaputra and Lohit rivers in the north and the Dibru River in the south, giving it a distinct island-like configuration. The elevation is low, averaging just above 100 metres, and the terrain is largely flat with gentle undulations created by old river channels, levees and silt deposits.

Floodplain Ecology and Swamp Forests

The park’s ecology is shaped by the annual flood cycle of the Brahmaputra and its tributaries. During the monsoon, large portions of the park are inundated, replenishing soil nutrients and recharging wetlands. As the waters recede, fresh grasslands emerge on exposed riverine sandbars, attracting herbivores and ground-nesting birds. Dibru-Saikhowa is also noted for its extensive salix swamp forests – stands of willow and other flood-tolerant trees growing in seasonally waterlogged conditions.

The forest types within the park range from moist mixed semi-evergreen and moist deciduous forests to canebrakes, reed-beds and tall grasslands, creating a mosaic of habitats that supports a wide variety of species.

Rivers, Channels and Wetlands

The braided channels of the Brahmaputra and its tributaries weave around the park, forming oxbow lakes, backwaters and low-lying marshes. These wetlands sustain a rich aquatic food chain—from plankton and invertebrates to fish, reptiles, waterbirds and mammals. The constant reshaping of sandbars and islands gives Dibru-Saikhowa a dynamic, ever-changing character rarely seen in more static terrestrial parks.

Flora and Fauna of Dibru-Saikhowa

Dibru-Saikhowa is widely recognised as a stronghold of biodiversity. Its vegetation includes semi-evergreen forests, mixed deciduous patches, littoral and swamp forests and extensive grasslands. Major trees include species such as Bombax ceiba (silk cotton), Mesua ferrea, Terminalia species, Ficus species and various riverine trees that tolerate periodic flooding. Tall grasses such as Imperata cylindrica, Phragmites karka and Saccharum species dominate many open tracts.

Mammals

The park supports a variety of mammalian fauna characteristic of the Brahmaputra valley. Notable species include:

• Feral horses – descendants of animals believed to date back to World War II, now semi-wild and a hallmark of the park’s grassy wetlands.
• Asian elephant – occasionally observed moving through forested areas and open meadows.
• Bengal tiger – a top predator, largely elusive but present in the park’s denser tracts.
• Leopard and smaller cats such as leopard cat.
• Wild water buffalo in certain zones.
• Hog deer, barking deer and wild boar commonly using grassland and ecotone habitats.
• Primates including capped langur and other arboreal species in forest patches.

The presence of large mammals, combined with an intact prey base, indicates that Dibru-Saikhowa continues to function as a healthy ecosystem within its floodplain setting.

Birdlife – A Paradise for Ornithologists

Dibru-Saikhowa is an Important Bird Area (IBA) and a renowned birding destination. More than 350 species of birds have been recorded, including several rare and threatened species. Among its notable avian inhabitants are:

• White-winged Wood Duck – one of the world’s rarest ducks, previously a focal species for conservation in this region.
• Jerdon’s Babbler and Black-breasted Parrotbill – two highly localised species associated with tall grass and reed beds.
• Spot-billed Pelican, storks, egrets and herons occupying wetland zones.
• Numerous species of raptors, kingfishers, bee-eaters, drongos and warblers.

During the monsoon and winter seasons, the park attracts migratory waterfowl and offers superb opportunities for bird photography. Many birdwatchers and eco-travellers plan wider wetland circuits linking areas like Dibru-Saikhowa with other major river delta systems using resources such as Sundarban Travel, which help illustrate how different floodplain and mangrove habitats contribute to continental-scale migration routes.

Unique Experiences and Things to Do

Boat Trips and River-Based Exploration

One of the defining experiences at Dibru-Saikhowa is exploring its waterways by boat. Travellers typically start from Guijan Ghat or other designated embarkation points, boarding country boats or motorised craft operated by authorised guides. As the boat glides through placid channels, visitors can observe riverine vegetation, feral horses grazing on distant sandbars, flocks of birds feeding in shallow waters and occasional sightings of dolphins in the main river channels.

Island Walks and Grassland Excursions

In certain seasons and under the guidance of forest authorities, short walks on stable islands and grassland tracts can be organised. These excursions allow visitors to examine plant communities, animal tracks and bird activity at closer range. Given the floodplain’s sensitivity, such activities are carefully regulated to minimise disturbance to wildlife.

Birdwatching and Photography

For birdwatchers and photographers, Dibru-Saikhowa offers a rich palette of subjects throughout the year. Early morning and late afternoon excursions yield particularly rewarding sightings, with soft light illuminating the misty water and grasslands. Serious birders often plan multi-day stays to cover different habitats – open water, reed beds, forest edges and scrublands.

Nearby Cultural and Natural Attractions

The surrounding Tinsukia and Dibrugarh region is known for its tea gardens, riverfronts and small towns with vibrant marketplaces. Many itineraries also include visits to nearby villages and viewpoints that showcase rural Assamese life and the cultural landscape of Upper Assam.
