Abstract
Human activities are the prime reasons that cause the decline of Chinese Pangolins(Manis pentadactyla)
throughout the world. Globally, the limited area is managed under protected area while most of the area lies outside
protected areas where anthropogenic threats are experienced high. Incessant increase in the threats has lead
Pangolins to a high risk of extinction in Nepal. This study was carried between October 2016 to January 2017 in
Balthali VDC of Kavrepalanchowk district using semi-structured questionnaire interview (n=117) to assess prevailing
anthropogenic threats to Chinese Pangolins habitat. Almost all respondents agreed that human activities are major
threats to Pangolins habitat. More than half of the respondents stated that poaching and illegal trade, habitat
destruction and haphazard construction and development activities like hotel and road constructions have resulted
in reduced Pangolins population. Moreover, intentional human induced forest fire, heavy grazing and a significant
increase in the use of chemical insecticides are diminishing the habitat of Chinese pangolins. To secure long-term
conservation of Chinese Pangolins their habitat we suggest promotion of public awareness activities.

Introduction
Human activities like hunting and illegal trading [1], deforestation
[2], forest fre [3], agriculture accretion [4], traditional beliefs [5],
forest fre and grazing are vital reasons for dramatic decline of
biodiversity throughout the world [6-8]. Chinese pangolins, like other
biodiversity components, are under severe threats due to similar
anthropogenic activities [9-12]. Local people usually consider
Pangolins as, a bush meat [13,14] and Asians consume Pangolins meat
as a delicacy and medicinal importance [15]. Killing of Pangolins due
to wrong myths and selling them for their scales is the biggest threat in
Kashmir, Pakistan [16]. Te Chinese Pangolins are critically
endangered species, which are estimated to have declined by over 90
percent in the past 21 years [9]. Moreover, Pangolins in the present
world are considered as most trafcked mammal in the world [17,18].
Pangolins are nocturnal mammals covered in tough, overlapping
scales. Tey feed on ants and termites and can roll themselves up into a
tight ball quickly for their protection [19]. Among eight species of
Pangolins across the globe, two species; Chinese pangolin (Manis
pentadactyla) and Indian pangolin (Manis crassicaudata) are found in
Nepal below 2,000 m elevation [20,21]. Chinese Pangolins are
distributed in Eastern, Central and Western Nepal [12,22]. Tey are
also found in China, Bhutan, India, Taiwan, Hong Kong SAR, Japan,
Bangladesh, Lao, Myanmar, Tailand, Vietnam, besides Nepal
[9,23-25]. All species of Pangolins includes Chinese Pangolins, sleep in
hollows and logs during day time and emerge out in the evening to
forage on ants and termites [19]. Tey have thick and long tail covered
with large (2-5 cm diameter), round overlapping scales formed from
fused hair, dorsally rounded and ventrally fattened, prehensile and
very muscular [26]. Male Chinese Pangolins are are larger than female
ones. Te mass of Chinese Pangolins ranges from 2.35 kg (young,
sexually matured female) to 7.0 kg (fat male); similarly body length
ranges from 545 mm (young female) and 795 mm (male) [27].
Pangolin scales, both whole and in powdered form, are used in
traditional Chinese medicines to treat a variety of diseases, including
psoriasis, infertility, to improve blood circulation, treat asthma, and
even cancer [28]. Large ear pinna, a post-anal depression in the skin
and a narrowing near the distal end of the tail helps to distinguish
Chinese Pangolins from other Asian Pangolins [29].
Te status of Chinese Pangolins is greatly afected by habitat
destruction in the country like Nepal [21], Taiwan [30] and Malaysia
[25]. Tere is a signifcant increase in poaching of Pangolins
throughout their range countries [15,31,32]. While international
trafcking is rising as a major threat to Chinese Pangolins [33],
nationally Eastern Nepal [5] and some places of Central Nepal like
Bhaktapur and Kavrepalanchowk districts [10] are considered more
vulnerable areas to Pangolins trafcking. Similarly, they are reported to
be under pressure from habitat destruction, especially by insecticide
