Study of plant species diversity & composition in Jungles of Assam

Study of plant species composition in local or regional level can contribute positively in global forest species composition monitoring program, and comparatively this kind of diversity assessment are less costly and easy to continue in the forests of developing countries. Northeast region of India is rich in species diversity because of its geographical position and the region being at the confluence of three major geographical realms of the world i.e. Indian, Chinese and Indo-Malayan. Variations of climatic conditions from tropical to sub alpine and altitudinal variations from low-lying plains of Brahmaputra to mountains of Arunachal Pradesh also boost the diversity of species in northeast region of India. However, plant species diversity in the forests of Assam, northeast India is still little understood. Understanding of forest structure is a pre-requisite to describe various ecological processes of forest. Qualitative and quantitative parameters are required to analyze for better understanding the characteristics of forest ecosystem.

Study sites

The study will be carried out in National Parks of Assam, North East India. There are five National Parks in Assam namely, Kaziranga National Park, Nameri National Park, Dibru Saikhowa National Park, Orang National Park and Manas National Park.

Kaziranga National Park:

It is a World Heritage Site and hosts two-thirds of the world's great one-horned rhinoceroses. Kaziranga is located between latitudes 26°30' N and 26°45' N, and longitudes 93°08' E to 93°36' E within two districts in the Indian state of Assam—the Kaliabor subdivision of Nagaon district and the Bokakhat subdivision of Golaghat distric. The National Park covering an area of 430 square kilometres.

Nameri National Park:

The national park located in the foothills of the Eastern Himalayas in the Sonitpur District of Assam.   The park covering an area of 200 square kilometres. Nameri shares its northern boundary with the Pakhuri   Wildlife Sanctuary of Arunachal Pradesh.

Dibru-Saikhowa:

Dibru-Saikhowa national park is located at about 12 km north of Tinsukia town of Assam covering an area of 340 square kilometres. It lies between 27°30' N to 27°45' N latitude and 95°10' E to 95°45'E longitude at an average altitude of 118 m (range 110-126m). It is also a biosphere reserve. The park bounded is by the Brahmaputra and Lohit rivers in the north and Dibru river in the south. It is situated in Dibrugarh and Tinsukia district of Assam.

Orang National Park:

It is located on the north bank of the Brahmaputra River in the Darrang and Sonitpur districts of Assam and covers an area of 78.81 square kilometres. It was established as a sanctuary in 1985 and declared a national park on 13 April 1999. The Orang National Park, lies on the north bank of the Brahmaputra river,delimited between 26.483°N 92.266°E and 26. 666°N 92.45°E.

Manas National Park:

The park area falls in five districts: Kokrajhar, Chirang, Baksa, Udalguri, and Darrang in the state of Assam. The National Park covering an area of 950 square kilometres.

Objective of the project

  • Analysis of plant diversity in National Parks of Assam.
  • Study the plant population structure in National Parks of Assam.
  • Study the natural regeneration status of tree species in National Parks of Assam.

 

Expected outcome of the project

  • Plant diversity of National Parks of Assam will be documented systematically.
  • Data set on distribution of ecologically and economically important plant species will be established.
  • The study will help to estimate plant population structure in different National Parks of Assam.
  • The findings may provide important indication for the management and conservation of plant diversity in India in general and Assam in particular providing data and conservation strategies.
  • The study will help to create a database on plant species richness including the density frequency abundance, dominance of plant species of each National Parks of Assam.
