Conservation
History
1907 and
1927 Parts of the present
National Park area notified as reserved forests. It was then called called
Manas R.F. and North Kamrup R.F & was used by the Cooch Behar
royal family and Raja of Gauripur as a hunting reserve.
October 1,
1928 Manas
declared a sanctuary on with an area of 360 km².
1951 and 1955 the
area was increased to 391 km².
1973 Manas
Tiger reserve was created
December 1985 Manas
declared a World Heritage site by UNESCO.
March 14 1989 Manas
declared as a Biosphere Reserve.
September 7,1990 Manas upgraded into a National Park with
the inclusion of Kahitama R.F. the Kokilabari R.F. and the Panbari R.F in the
eastewrn sector thereby increasing the area from 391 sq km to 500 sq km
1992 UNESCO declared it as
a world heritage site in danger due to heavy poaching and terrorist activities.
25 February 2008 The
area of Manas was increased to 950 km².
June 21st
2011, Manas was removed from
the List of World Heritage in Danger
and was commended for its efforts in preservation.

Conservation Values of Manas National Park
- The Burma Monsoon Forests of Manas lie on the borders between the Indo-Gangetic and Indo-Malayan biogeographical realms and is part of the Brahmaputra Valley Biogeographic Province. The combination of Sub-Himalayan Bhabar Terai formation with riverine succession leading up to Sub-Himalayan mountain forest makes it one of the richest biodiversity areas in the world.
- A total of 543 plants species have been recorded from the core zone of the National Park. Of these, 374 species are dicotyledons (including 89 trees), 139 species monocotyledons and 30 are Pteridophytes and Gymnosperms.
- The Park supports an impressive diversity and biomass of large wildlife species. Herbivores density in the grassland ecosystems of Manas rivals that of some East African grasslands (Eisenberg & Seidensticker 1976).
- Manas contains 22 of India's Schedule I (Wildlife Protection Act, 1972) mammals and at least 33 of its animals listed as threatened, by far the greatest number for any protected area in the country. Many are typical of Southeast Asian rain forest and have their westernmost distribution there, while other species are at the easternmost point of their range.
- Manas National Park is also a part of the Chirang-Ripu Elephant Reserve, declared in the year 2003 by Government of Assam, with an area of 2600 sq. km. The Manas National Park is perhaps the largest remaining safe home for elephants in entire Himalayan foothills in Assam. The Park plays a vital role in trans-boundary movement of elephants along the northern West Bengal, Bhutan and Arunachal Pradesh.
- The park is known for its rare and endangered endemic wildlife such as the Assam Roofed Turtle, Hispid Hare, Golden Langur and Pygmy Hog.
- Manas is famous for its population of the Wild water buffalo
- Over 450 species of birds including migrants have been recorded and about 350 breed in the area, 16 being endemic (Deb Roy, 1991) including the threatened Bengal Florican Houbaropsis bengalensis, a rare bustard. The Bengal Floricans of the National Park were estimated at 80 individuals with 24 male territories in the Park in 1988 (Narayan et al., 1989); this is a fifth of the world population.

Habitat
Manas National
Park is located in the Eastern
Himalaya foothills. The Manas river is the main river, a major
tributary of Brahmaputra river which flows
through the west of the park, further it splits into two separate rivers, the
Beki and Bholkaduba. Manas and five other small rivers flow through the
National Park which lies on a wide low-lying alluvial terrace below the
foothills of the outer Himalaya. The river
also acts an international border dividing India
and Bhutan.
The northern portion is
represented by the 'Bhabar' formation, which is very porous due to the deep
deposits of coarse detritus overlain by sandy loam and then a thin layer of
humus. The 'Terai' tract in the south consists of fine alluvial deposits with underlying
pans. Here, the water table lies very near to the surface.
There
are two major biomes present in Manas, the grassland biome and the forest biome
The
main vegetation types are:
- Sub-Himalayan Light Alluvial Semi-Evergreen forests in the northern parts.
- East Himalayan mixed Moist and Dry Deciduous forests (the most common type).
- Low Alluvial Savanna Woodland, and
- Assam Valley Semi-Evergreen Alluvial Grasslands which cover almost 50% of the Park.
Much of the riverine dry
deciduous forest is at an early successional stage. It is replaced by moist
deciduous forest away from water courses, which is succeeded by semi-evergreen
climax forest in the northern part of the park.
