    Ecology and management of the alpine landscape in the Khangchendzonga National Park, Sikkim, Himalaya
    (Wildlife Institute of India, Dehradun, 2007) Tambe, Sandeep; Rawat, G.S.
    In Sikkim the villagers practice a mixed livelihood strategy earning their income from agriculture, horticulture and animal husbandry. Livestock such as yak, cow, sheep, horse, buffalo and goats are grazed in the forests and alpine meadows of the state. During the beginning of the 20th century the forests of the state were demarcated and the Khasmahal and Goucharan forests were specifically set aside to meet the fodder and firewood demands of the villagers. The The genesis of this study lies in this conflict, wherein it was realized that a sound understanding of the ecology of the alpine meadows and pastoralism was needed to ensure effective management of these unique and fragile environments. It is with this objective that the present research study titled “Ecology and Management of Alpine Landscape in the Khangchendzonga National Park, Sikkim Himalaya” was initiated in 2004 which would evolve a long term conservation plan for the alpine zone of KNP. The study spans over a large spatial scale covering all the major watersheds of KNP and aims to bridge the knowledge gaps related to structure and composition of the alpine vegetation, alpine landscape characterization, sustainability of pastoralism, conservation strategy and co-management experiments. The purpose of the study is to provide a scientific basis for the long term conservation and sustainable and equitable use of the resources of the alpine zone of KNP to promote sustainable development in the state. The significance of the study is based in its ability to contribute in the formulation of a conservation plan for the alpine zone of KNP and a rational pastoral policy for the Sikkim Himalaya.

    Ecological impacts of anthropogenic pressures on high altitude forests along Bhagirathi catchment.
    (Wildlife Institute of India, Dehradun, 2001) Awasthi, Anjali; Rajvanshi, Asha; Rawat, G.S.
    The forests of Bhagirathi catchment in Garhwal Himalaya (Uttaranchal) have faced anthropogenic pressures since pre-British period. However, human induced disturbances increased during British period when the commercial exploitation of these forests started. It was during this period that the cultivation of potato and apple orchards were introduced in the region. These initial phases of transformation paved way for more recent changes in land-use practices and degradation of high altitude forests. The modern phase of degradation started with the construction of road to Gangotri in the middle of 20th century and opening up of Garhwal for tourism which led to development of infrastructural facilities and influx of mass tourism in the inner valleys. These added pressures on the remaining forests of Bhagirathi valley. 2. Ecological impacts of anthropogenic pressures and patterns and processes of forest degradation have not been quantified in this valley so far. Therefore, the present study was carried out in a part of the Bhagirathi catchment (78015' to 790 E long. & 30030' to 31 008' N lat.). The objectives of the study were: to assess the resource use patterns of villagers, transhumant communities and tourists, to assess the impacts of anthropogenic activities on forests and wildlife and to detect changes inland-cover classes over time and space. The study area is visited seasonally by various transhumant communities who also depend on the surrounding forests for a period of about six months. Four forms of transhumance viz., Nomadism, Semi-nomadism, Transmigration and Nuclear Transhumance were identified in the Bhagirathi valley. -Nomadism is followed by Gujjars, semi-nomadism by Gaddis, transmigration by Jadhs and Garhwalis and Nuclear transhumance by resident Garhwalis. Nomadic people have temporary hutsat both summer and winter settlements whereas transmigrants have permanent houses. Seminomadic and nuclear transhumants have one temporary and one permanent settlement. The impact of 'resource extraction by locals, transhumant communities and tourists on the forests was assessed. It was found that forests located close to villages (zone-I) and temporary settlements (zone-III) were under high lopping/cutting pressure.
