Raimona National Park History

On June 5th, 2021, Assam’s Chief Minister, Himanta Biswa Sarma, made the official declaration of Raimona National Park at a World Environment Day ceremony held at Gandhi Mandap in Guwahati, Assam. The official designation was made on June 9th, 2021 through the Assam Gazette Notification no. FRW.02/2021/27, dated June 8th, 2021, making Raimona National Park the sixth national park in Assam, India covering a vast forest area of 422 km2.

With the declaration of Raimona National Park, the Bodoland Territorial Region (BTR) now has two national parks including Manas National Park.

Raimona National Park was originally part of both the Ripu Reserve Forest and the adjacent Chirang Reserve Forest known as Chirang-Ripu Reserve Forest located at the westernmost buffer to Manas National Park & Tiger Reserve in the foothills of the Eastern Himalaya Biodiversity hotspot. Known for its historical elephant habitats with a diverse range of flora and fauna in its vast forests area, the Government of Assam declared Chirang-Ripu Reserve Forest as Chirang-Ripu Elephant Reserve in 2003 covering an area of 2600 km2.

The present Raimona National Park was initially proposed as Ripu-Chirang Wildlife Sanctuary. The park being part of Chirang-Ripu Reserve Forest its adjacent part was also mooted to be within.

The Raimona National Park falls under the DFO, Kacuhgaon Forest Division of CCF & CHD, (Chief Conservator of Forests & Council Head of the Department) BTR, Kokrajhar. The Kacuhgaon Forest Division has 4(four) ranges- 1. Eastern range -Athiabari range, 2. Sanfan Range, 3. Kochugaon Central range, 4. Western range -Raimona Range.

Construction of Railway Tramline in Kachugaon Forest in 1924

In 1906, a proposal was made for a 21-mile metre gauge tramline from Kokrajhar to the Saralbhanga River to supply railway sleepers at minimal benefit to the Forest Department and to obtain ballast at a low cost for the Eastern Bengal Railway. However, the proposed connection never materialized.

The Kachugaon Tramline was built to profit from the lucrative timber trade to Bengal. In 1924, 19-mile length a feeder forest tramline connection to the Eastern Bengal Railway’s trunk line between Fokiragram and Kachugaon was completed. It crossed through present-day Raimana National Park, Kochugaon, Hel, Kujrabguri, Amlaiguri, Samtaibari, and Dotma junction at Fokiragram.

As the Kachugaon forest tramway was completed the Conservator proposed purchasing two steam locomotives and twenty trucks to economize on extraction and transportation of timber. The Eastern Bengal Railway became the largest buyer of sleepers at nominal costs after the completion of Kachugaon tramline.

Meanwhile, this vintage tramway was totally destroyed during times. However, remnants of the engine, tramline and bogies of the tram are lying abandoned in Kachugaon.
