    Assessment of forest communities and dependence of local people on NTFPs in Askot landscape, Uttarakhand, Phase 1 - report
    (Wildlife Institute of India, Dehradun, 2015) Bisht, S.; Adhikari, B.S.; Uniyal, V.K.
    The Askot landscape represents a great diversity of ecosystems within a very short altitudinal range ie. from 600-7000 m. The assessment of vegetation was done during October, 2012 - October, 2014 covering the entire Gori sub-watershed between 600-2300 m in Askot Landscape in Pithoragarh district of Uttarakhand under Biodiversity Conservation and Rural Livelihood Improvement Project (BCRLIP). A checklist of 573 species of plants was prepared including some rare and endangered species, of which 124 trees, 112 shrubs, 24 climbers, 35 orchids and 278 herbs were recorded after carrying out a reconnaissance of the valley. The data collected for vegetation was analysed and forest communities were identified based on TWINSPAN analysis and various village surveys were conducted to find out the use of various Non Timber Forest Products such as fuelwood, fodder, timber, medicinal plants etc. in the study area. A total of 11 forest communities were identified in the Gori valley, viz. Macaranga pustulata, Shorea robusta, Engelhardtia spicata, Diploknema butyracea, Pinus roxburghii, Alnus nepalensis, Quercus leucotrichophora, Litsea umbrosa, Quercus lanuginosa, Q. leucotrichophora-Neolitsea cuipala and Sorbus foliolosa along an elevational gradient between 600-2300m. It was observed that the total basal area of Q. lanuginosa forest was highest (38.8 m2 ha-1) followed by Q. leucotrichophora (32.7 m2 ha-1) and Pinus roxburghii (31.8 m2 ha-1) and minimum for Q. leucotrichophora-Neolitsea cuipala forest (10.8 m2 ha-1) and Sorbus foliolosa forest (9.2 m2 ha-1). Among Non Timber Forest Products 24, 26, 16 and 24 species were being used as fodder, fuelwood, timber and medicinal plants, respectively. Q. leucotrichophora has the highest preference among fodder followed by Bauhinia vahlii, Boehmeria rugulosa and Ougeinia oogenensis. Lyonia ovalifolia followed by Rhododendron arboreum, Q. leucotrichophora and Woodfordia fructicosa among fuelwood; Shorea robusta followed by Alnus nepalensis, Pinus roxburgii and Q. leucotrichophora among timber; and (ii) Eupatorium adenophorum followed by Terminalia chebula, Zanthoxylum alatum and Pleurospermum angelicoides among medicinal plants. Lopping, forest fire and weed infestation were among major cause of disturbance to forest resources. Impact of lopping on Quercus lanuginosa, Rhododendron arboreum and Q. leucotrichophora, forest fire in W and NW aspects due to the dominance of Chir pine forests and infestation of Cannabis sativa, Eupatorium adenophorum, Urtica dioica and Impatience edgeworthii was highest in NW aspect. The common species used for medicinal purposes by the villagers were Emblica officinalis, Terminalia chebula, Litsea monopetala, Celtis australis, Bauhinia vahlii, Syzygium cumini, Myrica esculenta, Berginia ciliata, Oxalis corniculata, Eupatorium adenophorum, Adhatoda zeylanica, Terminalia chebula, Cissampelos pareira, Viola canescens, Fragaria nubicola, Tinospora cordifolia and different orchid species in Gori valley. Twelve potential plant indicator species viz., Chimnobambusa falcata, Eupatorium adenophorum, Alnus nepalensis, Quercus leucotrichophora, Quercus lanuginosa, Macaranga pustulata, Rhododendron arboreum, Pinus roxburghii, Aconitum heterophyllum, Dactylorhiza hatagirea Picrorhiza kurrooa and Pleurospermum angelicoides were identified based on the information collected during the surveys as well as through secondary information. The distribution map of each species was generated according to climatic zone in ArcGIS software along with their potential distribution range. Finally, a species richness map was prepared to show the high species richness zone in the study area.

    Effects of climate-change on riverine forests and indicator species along river Ganga in Uttarakhand: a multi-scale approach
    (Wildlife Institute of India, Dehradun, 2015) Ramesh, K.; Adhikari, B.S.
    The objectives were 1.Study the distribution pattern, range shift and population response of indicator species along the Ganga in Uttarakhand, from foot-hills to snout of the Gangotri glacier. 2. Quantify structure and functional attributes of vegetation along selected climatic ecotones. 3. Detect major drivers of landscape composition and configuration in space and time, and develop spatially explicit predictive models.

    Assessment of forest communities and dependence of local people on NTFPs in Askot landscape, Uttarakhand, Phase 1
    (Wildlife Institute of India, Dehradun, 2018) Bisht, S.; Adhikari, B.S.; Shrivastava, A.K.
    The study was conducted from January 2013 - October 2017 between 1000-3900 m in Gori and Dhauli sub-watersheds in Askot landscape in Pithoragarh district of Uttarakhand under Biodiversity Conservation and Rural Livelihood Improvement Project (BCRLIP). A preliminary information was collected regarding vegetation community in the landscape through existing knowledge and reconnaissance surveys. Vegetation plots were laid to study the structure, composition and regeneration pattern in various forest communities in the landscape. Questionnaire survey was conducted in different villages to study the use pattern of various Non-Timber Forest Products and state of traditional knowledge among local communities. A checklist of 596 species of plants was prepared including some rare and endangered species, of which 132 trees, 121 shrubs, 24 climbers, 36 orchids and 283 herbs were recorded after carrying out a reconnaissance of the landscape. The collected vegetation data was analyzed and 11 forest communities were identified based on TWINSPAN viz, P. roxburghii, Q. floribunda, Q. leucotrichophora, Q. lanuginosa, A. nepalensis, T. dumosa, Q. semecarpifolia, M. duthiei, A. pindrow, P. wallichiana and B. utilis. Lopping, weed infestation, forest fire and grazing are some of the threats to the plant biodiversity in the landscape. A Species richness map and disturbance level map was prepared in Arc Gis for the landscape. Based on collected information, a list of nine potential indicator species (Polygonum, Strobilanthes, Diplazium, Ageratina adenophora, Alnus nepalensis, Quercus leucotrichophora, Quercus lanuginosa, Macaranga pustulata, Rhododendron arboreum and Pinus roxburghii) were prepared. Three plant species (Ageratina adenophora, Alnus nepalensis, and Quercus leucotrichophora) were selected as indicator species, which will be used for long-term monitoring protocol to detect biodiversity change in the landscape by the local communities.
