  • Title
    A study on the behavior and colonization of translocated Greater One-horned Rhinos Rhinoceros unicornis (Mammalia: Perissodactyla: Rhinocerotidae) during 90 days from their release at Manas National Park, Assam India
    Type
    Journal Article
    Description
    Under the Indian Rhino Vision 2020, 18 wild Greater One-horned Rhinos Rhinoceros unicornis were translocated from two rhino bearing areas, Kaziranga National Park and Pobitora Wildlife Sanctuary to Manas National Park within the state of Assam, from 2008 to 2012. Following the release, the rhinos were closely monitored through radio tracking and direct observation to record their colonization pattern and behavioral adaptation to the new environment. Out of the 18 rhinos released at Manas, 16 (89%) rhinos dispersed in approximately the same direction from the release sites. The rhinos released from Pobitora Wildlife Sanctuary strayed more when compared to the rhinos from Kaziranga National Park. This paper describes the behavior patterns observed in Manas National Park, which may provide a useful alternative approach for future rhino translocation.

  • Title
    An ecological assessment of Hispid Hare Caprolagus hispidus (Mammalia: Lagomorpha: Leporidae) in Manas National Park, Assam, India
    Type
    Journal Article
    Description
    This study of the Hispid Hare Caprolagus hispidus in the tall grassland habitat of Manas National Park, Assam during 2009–2010 is the first detailed assessment in northeastern India.  We assessed the status, distribution, habitat use and key threats to this rare and little studied lagomorph species.  After interviewing local forest staff, 20 grassland patches within a survey area of 2.65ha were selected and transects (50x2 m) laid randomly to determine the presence/absence of Hispid Hare by recording pellets and other indirect evidence.  Hare presence was recorded in 17 grassland patches within transects dominated by Imperata cylindrica and Saccharum narenga.  Hispid Hare preferred dry savannah grasslands to wet alluvial grasslands during winter and avoided recently burned patches due to lack of cover and food.  The distribution pattern observed was clumped (s2/a = 6.2), with more evidence of Hispid Hare presence in areas where ground cover was dense, dry and away from water sources. Population density was estimated at 381.55 individuals/km2, which in comparison with other studies indicates that Manas National Park currently holds the highest density of Hispid Hare.  Habitat loss due to overgrazing, unsustainable thatch harvesting, burning of grassland, weed invasion, encroachment and hunting were identified as key threats which must be addressed to ensure survival of this threatened species in the Park.

  • Title
    An assessment of human-elephant conflict in Manas National Park, Assam, India
    Type
    Journal Article
    Description
    An assessment of human-elephant conflict was carried out in the fringe villages around Manas National Park, Assam during 2005-06. The available forest department conflict records since 1991 onwards were also incorporated during analysis. Conflict was intense in the months of July-August and was mostly concentrated along the forest boundary areas, decreasing with distance from the Park. Crop damage occurred during two seasons; paddy (the major crop) suffered the most due to raiding. Crop maturity and frequency of raiding were positively correlated. Single bull elephants were involved in conflicts more frequently (59%) than female herds (41%), while herds were involved in majority of crop raiding cases. Of the single elephants, 88% were makhnas and 11.9% were tuskers. The average herd size recorded was 8 individuals, with group size ranging up to 16. Mitigation measures presently adopted involve traditional drive-away techniques including making noise by shouting, drum beating, bursting fire crackers and firing gun shots into the air, and using torch light, pelting stones and throwing burning torches. Kunkis have been used in severe cases. Machans are used for guarding the crops. Combinations of methods are most effective. Family herds were easily deflected, while single bulls were difficult to ward off. Affected villagers have suggested methods like regular patrolling (39%) by the Forest Department officials along the Park boundary, erection of a concrete wall (18%) along the Park boundary, electric fencing (13%), simply drive away (13%), culling (11%) and lighting the Park boundary during night hours (6%). Attempts to reduce conflict by changing the traditional cropping pattern by introducing some elephant-repellent alternative cash crops (e.g. lemon and chilli) are under experiment.
