Abstract: We conducted field surveys on the mammalian diversity
in the Tengchong Section of Gaoligongshan
National Nature Reserve in Yunnan Province, China, using camera trap and
transect method between April 2014 and May 2018. A total of 46 identifiable mammal species
were recorded, including one new record for China and nine new species for the Tengchong County. Of
the 46 species, nine are globally threatened (three Endangered and six
Vulnerable) and six are Near Threatened on the IUCN Red List of Threatened
Species. Species richness of most mammal
groups in Tengchong remains high compared to similar
sites in neighbouring countries; however, encounter rates for species
vulnerable to high hunting pressures were quite low and large carnivores,
except the Asiatic Black Bear, were either extirpated or at critically low
numbers. Future surveys should cover a
wider elevation range and a variety of microhabitats to increase the
probability of detecting the species not yet recorded. To enhance the conservation value of the
reserve for the diverse mammalian community, poaching and livestock grazing
should be further controlled; in addition, protection and restoration of
low-altitude forests should be encouraged.
Monitoring and research on selected flagship species should also be
conducted.

INTRODUCTION
Gaoligongshan Mountains (hereafter GLGS) is well-known for its rich
biodiversity and unique geomorphological features (Chan et al. 2019). It attracted visiting naturalists as early as
the 19th Century; the most notable among them were John Anderson,
George Forrest, Frank Kingdon-Ward, and Roy Chapman
Andrews, who made a series of significant mammal collections from GLGS. Anderson collected the type series of Yunnan
Giant Flying Squirrel Petaurista yunnanensis from the surroundings of Tengchong Town in 1868 (Anderson 1878) and the type
specimen of Yunnan Hare Lepus comus from Tengchong in 1917 (Allen 1938). The collection of insectivores and rodents
from GLGS by Forrest and Kingdon-Ward greatly
improved our understanding of these little-studied groups in the eastern
Himalaya (Thomas 1912, 1914, 1922; Hinton 1923). From the mid-20th Century,
research on the area’s mammals was carried out by Chinese zoologists, further
enhancing understanding of the mammalian fauna of the region, especially on the
species composition of communities and their geographic distribution across the
vast mountain range (Pen et al. 1962; Peng & Wang 1981). A baseline survey of Gaoligongshan
National Nature Reserve listed 89 mammal species for Tengchong
County, including five species of Chiroptera and 16
species of Muridae (Xue et
al. 1995).
In April 2014, we launched a systematic mammal survey
in the Tengchong Section of Gaoligongshan
National Nature Reserve (hereafter TC-GLGS).
We provide a report on the current mammal diversity and conservation
status in TC-GLGS based on camera trap and transect surveys conducted between
April 2014 and May 2018.
MATERIALS AND METHODS
Camera trap survey
The camera trap survey was conducted between September
2014 and May 2018. The total number of
camera trap stations was 147, and they covered elevations from 1,515m to
3,350m. Three models of infrared camera
traps (Loreda L510, Loreda;
SG-990V, Shenzhen Siyuan Digital Technology Company; Reconyx PC900, Reconyx) were
used. Camera traps were deployed in
microhabitats thought to likely maximize the probability of detecting medium-
to large-sized ground-dwelling mammals, such as animal trails, salt licks,
ridgelines, water sources, and underneath fruiting trees. A group of knowledgeable reserve wardens
assisted in identifying suitable locations for deploying camera traps, and
about 60% of our camera trap stations were selected based on their advice. Most of the cameras were mounted on trees at
a height of c. 30–40 cm from the ground at a distance of 2–4 m to the target
area. Time and date were automatically
recorded on each exposure. Commercial
lures (Hawbaker’s Weasel and Marten Lure) were used
at five camera trap stations as a trial to test the effectiveness for future
camera trapping study.
Non-random transects
Both diurnal and spotlighting transects were conducted
in addition to the camera trapping.
Forest trails, watercourses, and quiet forest roads were walked on to
complement the inefficiency of camera trapping for strictly arboreal species
and to maximize encounter rate of mammal species. Fifteen transects were surveyed, amounting to
a total of 180.76km and 172 man-days, covering elevations between 1,300m and
3,430m, during both the cold-dry and wet-warm seasons. During these walks, all observed animals were
recorded. Tracks, feeding signs, and
droppings which could be confidently identified were also recorded (see Table 2
for field signs recorded for each species).
Spotlighting surveys were conducted in 11 of these transects, amounting
to 37.27km; we walked along quiet roads, trails, and streams at a slow pace
(under 1km/h) with two or three observers (Table 1). Locations of our camera trap and transect
surveys can be found in Fig. 1.
Data analysis
We included all mammals detected except Chiroptera, Muridae, and Cricetidae, due to the difficulties in identifying species
in these groups, often because of taxonomic uncertainties (e.g., Zhang et al.
2016). We included distinctive species
of Insectivora in which field identification is
unequivocal; these included Gaoligong Forest Hedgehog
Mesechinus wangi,
Elegant Water Shrew Nectogale elegan, and Northern Treeshrew
Tupaia belangeri. Nomenclature followed Wilson & Reeder
(2005), Wilson et al. (2009, 2011, 2016), and Mittermeier et al. (2013). Some species incorporated the latest
taxonomic updates, and the reasons for these deviations from Wilson et al.
(2009) and Wilson & Reeder (2005) are explained in the respective species
account.
We defined a camera trap record as a notionally
independent record if it occurred 30 minutes or more after an image of the same
species at the same station. One trap
night was defined as a continuous 24-hour period of camera operation. To understand the species richness and
conservation value of mammals in TC-GLGS, we compared our camera trap data with
that from two protected areas in neighbouring countries with similar
geographic, climatic, and biogeographic affinities: Namdapha
National Park in northeastern India and Hkakaborazi National Park in northern Myanmar.
RESULTS
Between April 2014 and May 2018, there were 147 camera
trap stations set for 14,814 trap nights.
Together with 180.76km of transect lines, 46 species of non-volant
mammals were recorded; of these, there were five primates, 12 carnivores, and
10 ungulates. This included three
globally Endangered species (Phayre’s Langur Trachypithecus phayrei,
Red Panda Ailurus fulgens,
and Forest Musk Deer Moschus berezovskii), six Vulnerable species (Gaoligong Hoolock Gibbon Hoolock tianxing,
Stump-tailed Macaque Macaca arctoides, Asiatic Black Bear Ursus
thibetanus, Sambar Rusa
unicolor, Takin Budorcas taxicolor, and Chinese Goral Naemorhedus
griseus), and six Near Threatened species (Assamese Macaque Macaca assamensis,
Marbled Cat Pardofelis marmorata,
Tufted Deer Elaphodus cephalophus,
Burmese Red Serow Capricornis
rubidus, Chinese Serow Capricornis milneedwardsii,
and Black Giant Squirrel Ratufa bicolor) (IUCN 2018).
The Burmese Red Serow Capricornis
rubidus was newly recorded in China and nine
species were new to the Tengchong County
(Yellow-bellied Weasel Mustela kathiah, Stripe-backed Weasel M. strigidorsa,
Common Palm Civet Paradoxurus hermaphroditus, Marbled Cat Pardofelis
marmorata, Gongshan Muntjac Muntiacus gongshanensis,
Orange-bellied Himalayan Squirrel Dremomys lokriah, Spotted Giant Flying Squirrel Petaurista marica,
Asiatic Brush-tailed Porcupine Atherurus
macrourus, and Forrest’s Pika Ochotona forresti).
Of the 46 recorded species, 34 were detected by camera
traps, 10 by direct observation alone, and two by tracks and signs alone
(Sambar and Mishmi Takin). The
three species most frequently camera trapped during our survey were Malayan
Porcupine Hystrix brachyura,
Northern Red Muntjac Muntiacus vaginalis,
and Assamese Macaque Macaca assamensis.
A checklist of mammal species recorded in our survey
can be found in Table 2, and a selection of recorded species are illustrated in
Images 1 and 2. Accounts of species of
special interest (i.e., globally threatened, new Tengchong
records, or rare for GLGS) are provided below.
Detailed information for most recorded species can also be found in Chan
& Bi (2016).
Accounts on selected species
Gaoligong Forest Hedgehog Mesechinus
wangi (Not Assessed)
This Gaoligongshan-endemic
species was recently described, although the existence of a hedgehog in
southern GLGS was known by scientists and reserve staff as early as 2003 (Ai et
al. 2018). It has only been recorded
from Tengchong County and the surrounding areas,
which is at least 1,000km south of any known distribution of its
congeners. It is also the only Mesechinus species found in subtropical forest and
it occurs at elevations above 2,100m.
One individual was camera trapped on 16 October 2014 at 24.9760N
& 98.7410E; another image was obtained on 19 November 2017 at
24.9700N & 98.7470E.
An individual was found at night in disturbed mid-montane moist
evergreen broadleaf forest at ca. 2,100m in August 2017.
Rhesus Macaque Macaca
mulatta (Least Concern)
Only recorded in forests under 2,000m. It appears to be restricted to the lower
elevation band between 1,300m and 2,000m in Tengchong,
similar to observations elsewhere in the eastern Himalaya (Mishra et al.
2006). This distribution pattern may be
in part due to competition with the two larger-sized macaque species common in
higher elevations.
Stump-tailed Macaque Macaca
arctoides (Vulnerable)
Htun et al. (2008) marked the northern distribution limit
of this species at 25°N in China where Tengchong sits. TC-GLGS supports a healthy population of the
species based on the relatively high encounter rate. A recent camera trap survey in the nearby Lushui County (25.417–26.150 0N) detected this
species (Chen et al. 2016), marginally expanding its latitudinal limit further
north.
Phayre’s Langur Trachypithecus
phayrei (Endangered)
An estimated population of around 500 individuals
persists in the southern part of TC-GLGS.
The biggest troop recorded had at least 70 individuals. Its relative rarity in the northern portion
is possibly a combination of past hunting pressure and the fact that Tengchong is at its northern distribution limit in China
(Chen et al. 2016; Gao et al. 2017).
Gaoligong Hoolock Gibbon Hoolock tianxing
(Vulnerable)
This recently described gibbon is proposed to be
listed as Endangered under the IUCN Red List criteria; however, more robust
data on the conservation status of different subpopulations of H. tianxing is needed (Fan et al. 2016). A survey conducted in 2016 recorded at least
17 gibbons in six family groups in Tengchong, and the
subsequent survey confirmed an additional group; the current population stands
at 20 gibbons in seven groups. The Tengchong population is of particular research and
conservation importance because it is both the northernmost and the largest
subpopulation in China (Chan et al. 2017).
Asiatic Black Bear Ursus
thibetanus (Vulnerable)
Bears in eastern and southeastern
Asia are subject to high hunting pressures (Robinowitz
& Khaing 2002; Mishara
et al. 2006). In TC-GLGS, the Asiatic
Black Bear remains widespread and not uncommon despite the disappearance of
other large carnivores. Feeding and
other signs from this species were commonly seen during fieldwork, and it was
recorded in 13 camera trap stations.
Breeding was confirmed by an adult with cub camera trapped in November
(Image 1e). There are human-bear
negative interactions resulting in casualties on both sides annually.
Red Panda Ailurus fulgens (Endangered)
The Red Panda is widespread and common in
TC-GLGS. It mostly occurs in the
higher-elevation mixed broadleaf forest with dense bamboo undergrowth just
below the treeline. Their droppings,
containing only coarse plant fragments with distinctive shape and colour, were
frequently seen in this preferred habitat.
Yellow-bellied Weasel Mustela
kathiah (Least Concern)
A new record for Tengchong. One individual was camera trapped on 14 May
2016 at 25.8020N & 98.7000E, making it the
northernmost record for GLGS. Another
camera trap image was obtained on 08 November 2016 at 25.1200N &
98.7080E. We obtained three
additional camera trap images of a Mustela
fitting the size and colouration of M. kathiah;
however, the possibility of those being Stripe-backed Weasels cannot be
excluded.
Siberian Weasel Mustela
sibirica (Least Concern)
Siberian Weasel was camera trapped on 07 and 12
January 2016 at 25.7580N & 98.7160E. Wang (2003) opined that Siberian Weasel in
Yunnan is an undescribed taxon, but did not provide further details. Our camera trap images show animals
superficially similar to M. s. moupinensis from
western Sichuan Province, with reddish-brown coat and a long black-tipped tail
(Gao 1987). Online images of Siberian
Weasels from northeastern India show animals with
similar pelage and identified as M. s. subhemachalana
(Choudhury 2016). A taxonomic study of
these forms including the Tengchong population is
warranted.
Stripe-backed Weasel Mustela
strigidorsa (Least Concern)
A new record for Tengchong. One individual was observed in the riparian
evergreen broadleaf forest at 25.7530N & 98.7040E on
28 April 2014 (Chan & Zhao 2014). As
with other weasel species, Stripe-backed Weasel is likely to be under-recorded
in Tengchong due to low detectability by camera traps
and simply by being “an inconspicuous denizen of chronically under-surveyed
regions” (Abramov et al. 2008).
Common Palm Civet Paradoxurus
hermaphroditus (Least Concern)
A new record for Tengchong. Recorded at four camera trap stations in the
southern part of TC-GLGS. Our record at
25.1160N marks its northernmost distribution in GLGS.
Marbled Cat Pardofelis
marmorata (Near Threatened)
A new record for Tengchong. We obtained 54 notionally independent records
at 12 camera trap stations, all north of 25.7330N. Our camera trap data shows that Marbled Cat
is more diurnal than the sympatric Leopard Cat.
Forest Musk Deer Moschus
berezovskii (Endangered)
All musk deer are heavily hunted throughout their
ranges and are in serious decline (Robinowitz & Khaing 2002; Mishra et al. 2006). This species was thought to have been
possibly extinct in TC-GLGS. Camera
traps recorded the species at six camera trap stations, all north of 25.7330N.
Tufted Deer Elaphodus
cephalophus (Near Threatened)
This species appears to prefer higher elevation
broadleaf forest in TC-GLGS—it was only recorded between 2,296m and
3,113m. Repeated camera trapping and
field surveys failed to record the species in northern Myanmar (Harris &
Jiang 2015), but camera trap images from TC-GLGS obtained on the international
border suggest that the species must occur across the border in the high
mountains of Kachin State in Myanmar.
Gongshan Muntjac Muntiacus gongshanensis (Date Deficient)
A new record for Tengchong. One male and one female were camera trapped
on 04 May 2018, at 25.7590N & 98.7190E; a female was
camera trapped on 07 May 2018 at the same site.
Similar to observations in northeastern India
(Choudhury 2009) and southeastern Tibet (Schaller
& Rabinowitz 2004), the Northern Red Muntjac was also camera trapped
at the same site, indicating that the habitats of the two muntjac species have
some overlap. Gongshan
Muntjac is reported to occur in western Yunnan between 25–28.167 0N
(Timmins & Duckworth 2016), but we could not find any published record from
Tengchong at 250N. Our finding is the first verifiable record of
the species in Tengchong.
Sambar Rusa
unicolor (Vulnerable)
According to interviews with local inhabitants, this
large deer is close to local extirpation following rampant hunting in the
1980s–2000s. We had no camera trap record
but tracks and droppings of this species were found at 25.5270N
& 98.7440E in moist evergreen broadleaf forest on 12 March
2015. Targeted survey should be
conducted to clarify its distribution and status in Tengchong.
Mishmi Takin Budorcas
taxicolor (Vulnerable)
The IUCN Red List considered the takin as a single
species with four subspecies (Song et al. 2008). We followed Groves & Grubb (2011) and
Wilson & Mittermeier (2011) and treated the four as full species; the GLGS
population is Mishmi Takin B. taxicolor. There are two disjunct populations of Mishmi
Takin in China, one in southeastern Tibet and another
in GLGS (Song et al. 2008); the current distribution in GLGS extends from Gongshan in the north (28.3170N ) to Tengchong in the south (24.0330N). Historically, it was also reported further
south in the Yingjiang County (24.0330N)
(Yang & Du 2006), but this southernmost population is believed to be
locally extinct. This is a high-altitude
species living along and above the tree line in TC-GLGS. Ai (1996) estimated that around 300
individuals lived in southern GLGS, but the population seems to be in
decline. We failed to camera trap any
during the survey but found fresh tracks, droppings, and feeding signs. Monitoring and scientific study is needed to
shed light on the causes of the observed range retraction and population
decline, especially in view of climate change.
Burmese Red Serow Capricornis rubidus
(Near Threatened)
A new record for China. The first animal was camera trapped in the
winter of 2014 (date and time unavailable due to camera malfunction) at 25.7970N
& 98.6340E. A single
animal was camera trapped on 24 August and 28 October 2017 at 25.7610N
& 98.7240E. An adult was
directly observed and video-recorded at the same site on 25 November 2017. It had also been camera trapped in the nearby
Lushui County of GLGS, but the animal was
misidentified as Chinese Serow Capricornis
milneedwardsii (Chen et al. 2016). A scientific paper is being prepared to
report this discovery (Chen Yixin, pers. comm., March
2018).
Orange-bellied Himalayan Squirrel Dremomys
lokriah (Least Concern)
A new record for Tengchong. A high elevation squirrel in TC-GLGS; the
highest count was 13 individuals at Nanzhaigongfang
(25.2880N & 98.7380E, 3,150m) on 06 May 2017, which
represents the southernmost distribution of D. lokriah
in China. According to Li & Wang
(1992), the Tengchong subspecies is D. l. subflaviventris. Population
decline has been reported in northeastern India
because of hunting and habitat loss (Dollo et al. 2010). High altitude forests in TC-GLGS are
well-protected and the squirrel is not hunted locally, but the impact of
climate change should be monitored.
Asian Red-cheeked Squirrel Dremomys
rufigenis (Least Concern)
It is restricted to lower altitude forests in TC-GLGS,
with 10 notionally independent camera trap records at 25.1140N &
98.6750E and two observation records during our study. One individual was photographed at Linjiapu at 25.2860N & 98.7010E
on 28 August 2016. Two animals were
photographed together at 25.0160N & 98.6820E on 10
May 2016. The only previous Tengchong record is of an old specimen from Jietou section at 25.3170N, which marks the
northernmost distribution in GLGS (Chen & Qu 2010).
Spotted Giant Flying Squirrel Petaurista
marica (Least Concern)
Sometimes recognized as a subspecies of P. elegans (Choudhury 2016; Wilson et al. 2016). We followed a molecular study which pointed
out that P. e. marica from China and northern
Indo-China is distinctive and should be elevated to full species status (Li et
al. 2013). New record for Tengchong with the only record at Dahaoping
Section at 24.9720N & 98.7300E, which marks the
northernmost global distribution for this species.
Yunnan Giant Flying Squirrel Petaurista
yunnanensis (Data Deficient)
This is the most common and widespread flying squirrel
species in TC-GLGS. The species was
formerly considered a subspecies of P. philippensis,
but recent genetic studies indicate that it is taxonomically distinct (Li et
al. 2013). Yunnan Giant Flying Squirrel
is not yet assessed by the current IUCN Red List, and its full
distribution range and population trend are unknown (Wilson et al. 2016). Tengchong is the
type locality for the species; more survey and basic research to clarify its
distribution, population status, and natural history are needed to clarify its
conservation needs.
Asiatic Brush-tailed Porcupine Atherurus
macrourus (Least Concern)
A new record for Tengchong. It was relatively widespread and common in
this survey. It was captured at 17 out of the 147 camera trap stations; therefore,
the lack of previous records seems surprising.
Our record at 25.7660N also marks the northernmost of its
distribution in GLGS.
Forrest’s Pika Ochotona forresti (Least Concern)
New record for Tengchong. According to Ge et al. (2012), O. forresti is the only Ochotona species in
southern GLGS. One individual was camera
trapped at 25.6250N & 98.7380E on 14 May 2015, which
represents the southernmost record of its global range.
Yunnan Hare Lepus comus
(Least Concern)
Tengchong is the type locality of Yunnan Hare, and the species
mainly lives in shrubland and open habitats in lower elevations outside
TC-GLGS. One individual was observed at
25.6480N & 98.6780E during spotlighting survey, another individual
was observed during the daytime at 25.3990N & 98.7100E. According
to our data and interview result, the Tengchong
population is in decline due to land-use change and hunting. The conservation status of Yunnan Hare in Tengchong deserves some focused attention.
DISCUSSION
Importance of transect survey
The use of camera trap for wildlife research has
become a mainstream tool for mammal research and surveys (Wemmer
et al. 1996), particularly in research involving rare and/or secretive species
(Cutler & Swann 1999; Rowcliffe & Carbone
2008). Some species, however, are
strictly or mainly arboreal and therefore are rarely recorded by camera traps
(e.g., Small-toothed Palm Civet: Duckworth & Nettelbeck
2008; Willcox et al. 2012). This
highlights the importance of conducting non-random transect survey to
compliment camera trapping in compiling a comprehensive mammal checklist for a
study area.
Twelve of the 46 mammal species recorded (26.1% of
total) were only detected by direct observations, which clearly illustrates the
value of employing different methods in mammal surveys. Daytime observation is particularly effective
to detect primates (e.g., Gaoligong Hoolock Gibbon),
agile small mammals (e.g., weasels and squirrels), as well as open
habitat and fossorial species (e.g., Chinese Bamboo Rat and Yunnan Hare). Spotlighting survey is, in our opinion, the
only effective way to survey for flying squirrel diversity.
Rare or unrecorded species
Some species were rarely recorded, suggesting they are
rare in TC-GLGS or that camera trap placement was ineffective at recording the
presence of these species. While some
are believed to be genuinely rare, such as Forest Musk Deer and Gongshan Muntjac, others are probably more abundant than
our records show and simply evaded our survey methods. The three weasel species, for example, were
rarely recorded, but villagers consider them not uncommon and reported that
poultry-raiding is a regular event.
Although most of our study areas are well-protected at present, past
anthropogenic activities, particularly hunting, have greatly decimated
populations of the more sensitive mammals in Tengchong. The complete absence of obligate large
carnivores in TC-GLGS may be explained by a combination of the following
factors: (1) our survey sites were at higher elevations in which biomass is
naturally lower; (2) the almost complete clearance of extensive natural
habitats below 2,000m means some species may be living at their upper elevation
limits which restrain population growth; and (3) past rampant hunting in and
around TC-GLGS has decimated populations of carnivores and has suppressed the
ungulate populations.
We failed to detect 24 mammal species (excluding Chiroptera and Muridae) previously
confirmed from Tengchong (Xue
et al. 1995; Zhang 1997; Wang 2003; Chen & Qu 2010). Of these unrecorded species, some have
specific niches which were not well-covered by our survey, such as Small Indian
Civet Viverra indica
and Jungle Cat Felis chaus
of mixed agricultural landscape in lower elevations or Crab-eating Mongoose
associated with lower elevation forests.
The rest are either targets for the wildlife trade (e.g., Bengal Slow
Loris, pangolins, and Eurasian Otter) or large carnivores, and we believe
hunting is the primary reason of their absence (Table 3).
There is no
reliable evidence suggesting the presence of Tiger Panthera
tigris, Leopard Panthera
pardus, Gray Wolf Canis lupus, and Sumatran Rhinoceros Dicerorhinus sumatrensis
after the 1990s. The last confirmed
record of Sumatran Rhinoceros in Tengchong was in
1949 (Wang 2003) and that of Tiger and Leopard were in 1983 and 1985,
respectively (Chen & Qu 2010). The
extinction of megafauna in Tengchong comes as no
surprise as they are reported to be (near-)extinct in other sites of the
eastern Himalaya with vast forest tracts and much lower human populations
(Rabinowitz & Khaing 2002; Datta
et al. 2008). Our data suggest that
ungulate densities are relatively low in TC-GLGS, and prey depletion is one of
the major factors affecting the survival of large carnivores (Datta et al. 2008).
The Asiatic Black Bear is the only large carnivore that remains
relatively widespread and common, which is a facultative carnivore and lives on
a much broader diet. Nonetheless, local
villagers occasionally reported big cat pugmarks, large carnivore scats with
Muntjac hoof remains, and livestock kills in recent years. Mesocarnivores such
as Clouded Leopard Neofelis nebulosa, Golden Cat Catopuma
temminckii, and Dhole Cuon
alpinus may survive in extremely low
numbers. We found no fresh burrows of
pangolins; pangolins were occasionally reported by local villagers, but their
numbers must be exceedingly low, if still present. Other restricted-range and little-known
small-sized species, such as Anderson’s Squirrel Callosciurus
quinquestriatus and Forrest’s Rock Squirrel Sciurotamias forresti,
were most likely overlooked by us or have highly restricted distribution not
yet surveyed by us. Further survey
should cover a wider range of elevations and microhabitats to increase
detection probability to understand their conservation needs.
Conservation
implications
This survey demonstrated that TC-GLGS remains an
important site for the conservation of high-altitude mammals in the eastern
Himalaya, comparable to similar sites in the neighbouring countries (Mishra et
al. 2006; Than Zaw et al. 2008). The mammalian community of TC-GLGS appears to
be recovering from past heavy disturbances, particularly hunting, but we failed
to record any large carnivores except
the Asiatic Black Bear, and densities of ungulates are relatively low compared
to well-protected areas such as Hong Kong (Bosco Chan, unpublished data). Nevertheless, anthropogenic disturbances have
significantly reduced after more than 30 years of protection; we observed
abundant wildlife signs including those of the Asiatic Black Bear Ursus thibetanus. Evidence of hunting and logging were rarely
found, and camera traps detected very low human traffic. Poaching and illegal logging still exist near
the international border with Myanmar, often involving cross-border criminals
based on the reserve forest crime database.
Our camera traps also recorded some livestock grazing in the
southernmost and northernmost sections of the reserve. A determined effort to stamp out poaching and
livestock grazing will be helpful to the recovery of mammal populations in
TC-GLGS, before reintroduction of large carnivores can be considered.
Tengchong is located in the southernmost part of GLGS and is
the northern distribution limit for many species from the Indo-Malayan
biogeographic realm. Some of the missing
species, such as Bengal Slow Loris, Small Indian Civet, Crab-eating Mongoose,
and Jungle Cat, are adaptable species of predominantly low elevations and will
greatly benefit from better protection effort of lower altitude forests below
2,000m (Duckworth et al. 2005; Jennings & Veron
2011).
Long-term monitoring and research on selected mammal
species, such as the rare Gaoligong Hoolock Gibbon
and Marbled Cat, high altitude species susceptible to climate change such as
Mishmi Takin and Orange-bellied Himalayan Squirrel, and species vulnerable to
high hunting pressure such as Forest Musk Deer and Sambar, should be conducted
to assess management effectiveness. If
needed, necessary conservation interventions should be effected.
