Nagarjunsagar Srisailam Tiger Reserve: A Wildlife Haven

Nagarjunsagar Srisailam Tiger Reserve, located across Andhra Pradesh and Telangana, holds the distinction of being the largest tiger reserve in India. Spread over an impressive expanse of more than 3,700 sq km in the rugged Nallamala Hills of the Eastern Ghats, the reserve is a stronghold for big cats and an ecological treasure trove. Established under Project Tiger in 1983, it plays a pivotal role in safeguarding India’s national animal and preserving one of the country’s most unique forest landscapes.

The reserve is home to a healthy population of Bengal tigers, leopards, and dholes (wild dogs), supported by abundant prey such as spotted deer, sambar, and wild boar. Srisailam and Amrabad zones are among the most promising areas for tiger sightings. For wildlife photographers, this reserve is a paradise, offering raw wilderness, natural lighting in open valleys, and thrilling opportunities to capture elusive predators in their natural habitat.

Apart from its predators, the reserve is also famous for the Nagarjunsagar Dam, one of the largest man-made reservoirs in the world, which enriches the ecosystem and attracts diverse bird species. Its ecological richness, combined with spiritual significance from ancient temples nestled in its forests, makes it one of the most fascinating Tiger Reserves in India, blending wildlife, culture, and heritage.

History, Geography & Landscape

The Nagarjunsagar Srisailam Tiger Reserve was officially established in 1983, but its forests have a much older history. Once the hunting grounds of local rulers and dynasties, the Nallamala Hills were gradually recognised for their immense ecological value. The declaration of this region under Project Tiger marked a turning point, transforming it into one of the most significant protected areas among all Tiger Reserves in India.

Geographically, the reserve lies within the Eastern Ghats, stretching across five districts in Andhra Pradesh and Telangana. Its vast terrain is characterised by rugged hills, deep valleys, and expansive plateaus. The forests are largely dry deciduous, interspersed with teak, bamboo, and scrub vegetation. Unlike the dense evergreen forests of the Himalayas or Western Ghats, the Nallamala landscape offers wide, open spaces where wildlife sightings can be unexpectedly rewarding.

The lifeline of the reserve is the Krishna River, which meanders through its core and feeds the massive Nagarjunsagar Dam. Seasonal streams and smaller tributaries carve valleys, forming natural watering points for animals. The climate here varies sharply—summers are hot and arid, the monsoon brings lush greenery, and winters are cool and pleasant, making it an ideal time for safaris. This combination of history, geography, and landscape creates a unique setting, offering both ecological significance and scenic beauty for visitors.

The Nagarjunsagar Srisailam Tiger Reserve is not only about its tigers but also a treasure house of biodiversity.

Mammals

Apart from tigers and leopards, the reserve is home to the sloth bear, wild dog (dhole), gaur, chinkara, spotted deer, sambar, nilgai, and four-horned antelope. Smaller mammals like the Indian pangolin and slender loris are also found here.

Birds

With over 180 species recorded, birdlife is equally captivating. Notable sightings include the grey hornbill, crested hawk-eagle, peafowl, paradise flycatcher, Indian pitta, and painted stork. The Krishna River also attracts migratory waterbirds.

Reptiles & Amphibians

The reserve shelters a variety of reptiles such as king cobra, python, Russell’s viper, monitor lizard, and star tortoise. Several species of frogs and toads thrive in seasonal streams during monsoon.
