    capture and tagging of black-necked crane (Grus nigricollis) and Bar-headed goose (Anser indicus) in Changthang Cold Desert Wildlife Sanctuary, Ladakh
    (Wildlife Institute of India, Dehradun and Department of Wildlife Protection, Jammu and Kashmir, 2014) WII
    Modern satellite tracking techniques aid to study precise migration paths, stop over sites and habitat utilization. There is no information is available on migration patterns of water birds in Ladakh. Therefore we conducted a satellite based telemetry study on Black-necked crane (BNC) and Bar-headed goose (BHG) in Changthang Cold Desert Sanctuary. We initially did a reconnaissance survey, we counted 57 cranes and 182 geese in sanctuary, based on which; we shortlisted Chushul, Hanle and Rhongo mashes for capture and tagging of birds. We captured four BHG at Chushul using noose traps, two of them fitted with Platform Transmitter Terminals (PTT) and with conventional neck bands and rings. Whereas two other BHG were collared with only conventional neck bands and tagged with tarsus rings. We also fitted two BNC with PTT and tarsus bands, first at Chusul and second at Rhongo. Till date we received 810 locations with different location classes through ARGOS out of which 558 locations from class 3, 2, 1 & 0 were used for analysis. Preliminary findings revealed that maximum distance travelled by PTT fitted cranes from date of tagging till December 2013 ranged between 279 and 329 km and geese between 361 and 945 km. One of the PTTs of BHG stopped functioning from 30/10/2013 and another BHG fitted with PTT travelled to near Himachal Pradesh Border. Whereas two BHG fitted with only neckband and rings were reported from Gharana Wetland, Jammu. This study was able to track migration of BHG from Ladakh to Jammu via Himachal Pradesh (probably Pong Dam). The movement pattern of the PTT fitted birds are being tracked and may yield further information on their movement pattern and habitat utilization

    Biodiversity impact assessment report of mandal Thang field firing range Leh, UT Ladakh
    (Wildlife Institute of India, Dehradun, 2023) WII
    The Shyok valley forms the north-eastern edge of KWS, comprises of Galwan valley and Daulat Beg Oldi (DBO) plains situated between Siachen and Karakorum mountain ranges. The cold arid landscape of the Shyok valley is characterised by high intensity of solar radiations, tremendous ruggedness of terrain, seasonality in resources, and low productivity. The entire area is steep semi-arid habitat, long riverine habitat, glaciers and towards the north the plains habitat. The remoteness and tough terrain support a unique arid flora and fauna found in this region. Due to the its harsh and cold climatic and topographic conditions, vegetation cover is sparse, along the river the vegetation cover is sometimes dense. This riverine habitat along the Shyok river provide crucial habitats for small mammals and birds. The vegetation in the valley comprises of mixed scrub steppe, sparse vegetation cover, plantation in the lower part of the valley, herbaceous, sedge meadows and grasslands in the north, and riverine vegetation. The dominant plant species in this area were, Myricaria spp, Artemisia spp. Eurotia spp, Lonicera spp, Kobresia spp, Nepeta spp, and, Ephedra spp. The valley is home to endangered faunal species, such as the Tibetan antelope (Pantholops hodgsonii) which is endemic to this region in the entire landscape, snow leopard (Panthera uncia), Himalayan/Tibetan wolf (Canis lupus chanco), and other important species. The valley is also home to many bird species (Bhatnagar and Wangchuk, 2001). Military and para-military presence has been predominant since the 1960s. Due to the strategic importance of the area the defence forces have deployed infrastructure, training camps, roads and firing ranges within this valley. The purpose of this study for Biodiversity Impact Assessment (BIA) was to identify, evaluate and report the potential wildlife effects of Military activities in the MTFFR. This process included identification of mitigative measures that may be undertaken to reduce or eliminate potential adverse effects, where appropriate
