The history of Dibru-Saikhowa National Park dates back to the early 20th century when it was primarily used for logging and hunting by the local tribes. However, the forest was recognized for its unique biodiversity and ecological significance, and efforts were made to protect it from further degradation. In 1929, the British colonial administration declared the area as a Reserve Forest, and later in 1971, it was declared a wildlife sanctuary.


Dibru-Saikhowa National Park’s geological marvels are a testament to the Brahmaputra River’s enduring influence over the millennia. The park’s landscape is shaped by alluvial deposits, continuously amassed by the river’s sediments over millions of years. On the south bank of the Brahmaputra, this mesmerizing terrain unfolds, boasting a blend of sand, silt, clay, occasional layers of gravel and pebbles, and sandy soil with high water retention. This fertile ground nurtures dense forests and lush wetlands.

In this vibrant region, seismic activity is common, giving rise to frequent earthquakes. The earth’s movements have left a striking mark, creating numerous fault lines and fissures in the rock formations. These dynamic forces have forged the park’s distinct topography, making Dibru-Saikhowa a captivating blend of geological wonders and thriving ecosystems.
