    Systematics and diversity of spiders (Araneae) in Nanda Devi Biosphere Reserve
    (Wildlife Institute of India, Dehradun, 2011) Quasin, Shazia; Uniyal, V.P.
    The present study was carried out in Nanda Devi Biosphere Reserve (NDBR), Uttarakhand, India, which is located in the northern part of the Western Himalaya in India, one of the important sites of wilderness and biodiversity in the Himalayan region. This study was selected for its conservation value, representation of biome and little existing information. The present study was conducted from January 2008 to July 2011. The study aimed to investigate the spider community structure along the altitudinal gradient and the influence of habitat covariates like vegetation types, ph, litter depth, humidity and temperature, on spider assemblages in the intricate landscape of the NDBR. The pattern of species diversity was explored using a set of standard methods and ecological indices. This study obtained the first comprehensive representation of the spider fauna in NDBR, which would help in assessing the status of spider diversity in the region keeping in mind its conservational value. This study revealed the relative importance of diverse habitat types on diversity and composition of spider assemblages in NDBR.

    Ecology of alpine arid pastures with special reference to livestock grazing in upper Dhauli valley, Nanda Devi Biosphere Reserve, Western Himalaya.
    (2018) Mitra, Monideepa; Adhikari, B.S.; Rawat, G.S.
    Pastoral practices have been in existence in the alpine region of the Himalaya since millennia.The region is characterized by the presence of diverse pastoral practices such as sedentary, nuclear trans-humane, semi-nomadic, and nomadic pastoralism. These practices have strongly influenced the vegetation and ecology of the alpine rangelands, including local biodiversity. The region is broadly divisible into two distinct eco-climatic zones, viz., a moistal pine zone of Greater Himalaya and cold arid zone of Trans-Himalaya. These zones differ considerably in terms of physiognomy, species composition, history of livestock grazing and their ability to withstand grazing pressure. The objectives of the study were (i) To study the patterns of livestock grazing in the study area, (ii) To assess resource use by livestock, (iii) To assess the pasture quality (floristic) and quantity (biomass) in the study area, and (iv) to assess overlap in resource use between wild ungulates and livestock. The study was conducted in Upper Dhauli valley, situated in the cold arid region of Nanda Devi Biosphere Reserve (hereafter NDBR; 30º 08’-31º 02’N, 79º 12’- 80º 19’E) in Uttarakhand. The study was conducted in 2012 and 2014

    Assessment of provisioning service and the recreational value of Nanda Devi Biosphere Reserve.
    (Wildlife Institute of India, Dehradun, 2015) Pariva; Hussain, S.A.; Badola, Ruchi
    The ecological services and the natural capital stocks that produce them are critical to the functioning of the earth’s life-support system. Because of the direct use of the structural value provided by natural ecosystems and in most cases of free access to such ecosystems they are under heavy utilization pressure. The harmful effects of degrading ecosystem services are being disproportionately borne by the poor and are contributing to the growing economic inequities as well as environmental hazards to which the poor are the most vulnerable. Present work aimed to understand the status of the provisioning and recreational services of the Nanda Devi Biosphere Reserve (NDBR) and their contribution in securing wellbeing of local communities. The study was carried out with five objectives: (a) assess the socioeconomic status of local communities in NDBR, (b) quantify the provisioning services of the Reserve in terms of resource extraction, (c) estimate the recreational and religious value of the Reserve and its contribution to local livelihoods, (d) assess the extent of human-wildlife conflicts in the Reserve; and to (e) examine the attitude of local communities towards the conservation of the Reserve.
