Chapter 1
INTRODUCTION
Snow leopard (Uncia uncia) is a member of family Felidae, subfamily
Pantherinae (Blomqvist, 1978; Nowak and Paradiso, 1983). On the basis of distinct
morphology and specific behavior it is placed alone in a separate genus (Pocock,
1917; Hemmer, 1972; Peters, 1980; Rieger, 1980). The historical range of snow
leopard is restricted to the mountains of central Asia, with core areas in the Altay,
Tien Shan, Kun Lun, Pamir, Hindu Kush, Karakoram, and Himalaya ranges
(Hussain, 2003). It is very thinly distributed across an area of 1.2 to 1.6 million
square kilometers (km2) and probably as much as 3 million square kilometers (Fox,
1994; Hunter and Jackson, 1997; Nowell and Jackson, 1996; Sunquist and
Sunquist, 2002).
It occurs at elevations of 3000 to over 5000 meters (m) in the Himalaya and
Tibetan Plateau, but as low as 600m in Russia and Mongolia (Sunquist and
Sunquist, 2002). It was also reported to migrate to lower elevations during winter in
northern Pakistan and some other countries, following movements of ibex and
markhor which are its prey species (Jackson and Hunter, 1996).
Snow leopard habitat consists of cold, arid and semiarid shrub land,
grassland or barren areas (Jackson and Hunter, 1996). Low temperatures, high
aridity, and harsh climatic conditions make its habitat among least productive of the
world’s rangelands (Mishra, 2001) and due to this, populations of prey are also
very low (McCarthy et al., 2005). Mostly snow leopards favor steep terrain broken
by cliffs, ridges, gullies, and rocky outcrops but if adequate cover to hide is present
they can occur in relatively flat or rolling terrain. Common travel routes and
marking sites comprise of mountain ridges, cliff edges, and well-defined drainages
(Ahlborn and Jackson, 1988).
Population density of snow leopard throughout its range is from less than
0.1 to over 10 individuals per 100 km² (Nowell and Jackson, 1996). The total snow
leopard population is judged between 4,500 and 7,500 across 12 countries of Asia
including China, Bhutan, Nepal, India, Pakistan, Afghanistan, Tajikistan,
Uzbekistan, Kyrgyz Republic, Kazakhstan, Russia, and Mongolia (Jackson et al.,
2005). However, its actual status is yet unknown. Even its currently occupied range
is poorly mapped because of limited funding, lack of trained wildlife biologists,
and difficult logistics which severely constrain surveys across the snow leopard’s
high, inhospitable terrain (Jackson et al., 2006).
In Pakistan, snow leopard is found throughout the mountain ranges of the
north, in all the districts of the Federally Administered Northern Areas (FANA), in
Chitral, Dir, Swat and Kohistan districts of Khyber Pakhtunkhwa and in the
northern part of Neelum Valley, District of Azad Jammu and Kashmir (Malik,
1997). The total snow leopard habitat available in Pakistan is about 80,000 km2 of
which about 40,000 km2 is considered to be its prime habitat (Fox, 1989). It occurs
in the Hindu Kush range in the Chitral District (Khyber Pakhtunkhwa), and in the
Karakorum Range of the Gilgit-Baltistan in the Gilgit, Hunza and Baltistan
districts. A good population of snow leopard is also reported from Shimshal area in
Hunza, but no density estimate is available (Wegge, 1988).
Snow leopard is categorized as “Endangered” according to The IUCN Red
List of Threatened Species (2009.1) and is listed in Appendix-I of the Convention
on International Trade in Endangered Species (CITES), which means that trade in
the animal and its body parts is illegal.
Snow leopard is legally protected in the Khyber Pakhtunkhawa, Gilgit-
Baltistan and in Azad Jammu and Kashmir through individual Wildlife Acts. The
NWFP Wildlife Act of 1975, prohibits the hunting, capturing and killing of any
‘protected animal’. Section 14 of the Act, specifically refers to trade and prohibits
the trade and/or sale in snow leopard, its trophies and its meat (Khan, 2002).
The long-term future of the snow leopard in Pakistan is under threat, mainly
due to retaliatory killings by farmers, and poaching for pelts and other body parts.
Species-focused conservation policies, particularly those targeting ungulates for the
promotion of trophy hunting, may constitute an additional threat to snow leopard
conservation in the region (Hussain, 2003). Snow leopard is under a number of
threats which are grouped into four broad categories by McCarthy and Chaperon
(2003). Category 1 (Habitat and Prey Related) includes habitat degradation and
fragmentation, reduction of natural prey due to illegal hunting, reduction of natural
prey due to legal hunting, reduction of natural prey due to competition with
livestock, reduction of natural prey due to disease, and fencing that disrupts natural
migration. Category 2: (Direct Killing or Removal of Snow Leopards) includes,
killing of snow leopards in retribution for livestock depredation, poaching snow
leopards for trade in hides or bones, museum collection of live animals, traditional
hunting of snow leopards, secondary poisoning and trapping of snow leopards, and
diseases of snow leopards. Category 3 (is about Policy and Awareness) involves
lack of appropriate policy, lack of effective enforcement, lack of trans-boundary
cooperation, lack of institutional capacity, lack of awareness among local people,
and lack of awareness among policy makers. Category 4 includes Other Issues
which are war and military related activities, climate change and human population
growth and poverty, an indirect threat (McCarthy and Chaperon, 2003).
More recent information on snow leopard’s population in Pakistan is
lacking. Based on surveys undertaken in the early 1970s, Schaller (1976) estimated
the total population of snow leopards in Pakistan to be around 150 to 200 animals.
Malik (1997) reported that the number could be around 400 animals. Recent
surveys undertaken in the Baltistan District of the Gilgit-Baltistan resulted in an
estimate of 90-120 animals in that District and 300-420 animals throughout
Pakistan (Hussain, 2003).
There are certain limitations and gaps in population estimates in Pakistan
because mostly these estimates are based on anecdotal information or interviews
and expert judgments. Thus their reliability is questionable. In few areas some
interviews and tag-based efforts have been done to determine the status of snow
leopard. These include Chitral Gol National Park (Malik, 1997), Khunjerab
National Park (Wegge, 1988) and some selected areas in Baltistan (Hussain, 2003).
These were the only areas where some field work was done to determine the
distribution and population size of snow leopard while majority of rest of its range
in Pakistan has not been yet surveyed.
Study Objective
The present study was designed to determine the status of snow leopard in
Laspur valley, Chitral (Khyber Pakhtunkhawa) by using multiple census methods.

REVIEW OF LITERATURE
Snow leopards is found in 12 countries across central Asia, China, Bhutan,
Nepal, India, Pakistan, Afghanistan, Tajikistan, Uzbekistan, Kyrgyzstan,
Kazakhstan, Russia, and Mongolia. China contains as much as 60% of the snow
leopard’s potential habitat. Inaccessible and difficult terrain, along with the
secretive nature of this rare cat helps account for the fact that either large parts of
its range have yet to be surveyed, or have been surveyed only rarely. Mostly snow
leopard is distributed along very sensitive international borders which make it
difficult to establish a reliable current status and distribution of species. Moreover,
the existing data base may be outdated because it mostly based on those surveys
which were conducted over a decade ago (McCarthy and Chaperon, 2003).
The population of snow leopard was estimated around 2000 in the early
1970’s. Fox (1989) placed the total snow leopard range at 1.23 million km2, with a
world population of 3,350-4,050 animals. These figures were updated 4,510 to
7,350 snow leopards within a total potential habitat area of 1,835,000 km2 (Fox,
1994). However, on the basis of available habitat, there could easily be as many as
6,000 to 8,000 snow leopards, especially given densities in known “hotspots” of the
order of 5-10 individuals per 100 km2 (Jackson et al., 2005).
The potential snow leopard range estimated in different countries includes;
117,653km2, 1,824,316km2, 103,000km2, 95,000km2, 131,000km2, for
Afghanistan, China, Mongolia, India and Russia, respectively (Chundawat et. al.,
1988; Hunter and Jackson, 1997; McCarthy, 2000; Poyarkov and Subbotin, 2002).
In Bhutan snow leopard range was calculated about 15,000km2 by Fox (1994)
while 7,349km2 was provided by Hunter and Jackson (1997) while in Nepal,
Russia, Kyrgyzstan, and Kazakhstan it is 30,000km2, 131,000km2, 126,162km2,
71,079km2, respectively (Koshkarev, 1989; Hunter and Jackson, 1997). Potential
habitat in Uzbekistan is 13,834 km2 was estimated by Hunter and Jackson (1997).
The population estimates of snow leopard available for various countries
include; 2000-2500 animals in China with as much as 60 percent of all snow
leopard ranges, 800-1700 individuals in Mongolia (McCarthy, 2000), about 500
individuals in India (Fox et. al., 1991), and 150-200 in Russia (Poyarkov and
Subbotin, 2002). There would be about 100 snow leopards in Bhutan (Jackson and
Fox, 1997) whereas Nepal has 350-500 individuals (Jackson and Ahlborn, 1990),
150-200 snow leopards are estimated to live in Russia (Poyarkov and Subbotin,
2002) and 113-157 snow leopards were estimated in Kyrgyzstan by Koshkarev
(1989). In Tajikistan snow leopard population was calculated at 200-300 by Sokov
(1990) population and 80-100 snow leopards by Buzurukov and Muratov (1994).
The total population of snow leopard in Uzbekistan was estimated at about 50
animals (Sludskiy, 1973; Braden, 1982).
Population estimates of snow leopards are really a guestimate based upon
surveys which were mostly undertaken over a decade ago, and or in the case of the
Central Asia Independent States when protected areas were in better shape than
they are today (McCarthy and Chaperon, 2003).
Fox (1994) estimated snow leopard range in Pakistan about 80,000 km2,
while the total number was placed at 100-250 by Schaller (1976) and at 300-420 by
Hussain (2003). A 300 km2 area in Chitral, known for snow leopard, was searched
but evidence of only four or possibly five were found (Schaller, 1976). Density
estimates are lacking, but assuming a mean density of 1/250 km2, the total
population for Pakistan would be no more than about 320 snow leopards. Snow
leopards also occur in the Hindu Kush range in the Chitral, and in the Karakorum
Range of the Northern Areas in the Gilgit, Hunza and Baltistan Districts. A good
population of snow leopard is also reported from the Shimshal area in Hunza, but
no density estimate is available (Wegge, 1988). Its presence in Azad Jammu and
Kashmir remains unconfirmed (Roberts, 1977).
Different methods have been used for population estimation of large
carnivores. Questionnaires, interviews, and sighting reports from local informants
have been used to get an approximate picture of carnivores distribution (Gittleman
et al., 2001) and sometimes animal abundance, of different species of large
canivores (e g., Henke and Knowlton, 1995; Hussain, 2003; Henke and Knowlton,
2005; Mishra et al., 2006). This is especially useful for rare species that have a
wide distribution. Chances of biases are always present (Linnell et al., 1998).
Hussain (2003) used an open-ended questionnaire for interviewing local herdsmen
about snow leopard presence in Baltistan. Sign surveys are probably the most
commonly used method for monitoring large carnivores. Transects are searched for
tracks, scats, scrape marks or any other sign of a passing carnivore (Linnell et al.,
1998). Several different methods of sign surveys have been used to determine
species distribution of most carnivore groups (Gittleman et al., 2001). Proper and
consistent identification of tracks, scats, burrows, and hair samples is a major
problem. Sign surveys are subject to observer bias (Long et al., 2007; McCarthy et
al., 2008).
Sometimes individuals are identified subjectively by comparing the
differences in track measurements and their numbers summed up per larger
carnivore species (Gusset and Burgener, 2005). Track counts can also be used for
population estimation of large carnivores (Siira et al., 2009). Wilting et al. (2006)
combined track classification method with a capture-recapture model to study
elusive cats which showed that the method is also practicable for a small area and
small population of carnivores. This technique is more efficient and best for most
species active in winter (Gittleman, 2001; Silveira et al., 2003; Wilting et al.,
2006). Failure to find tracks of animals (Silveira et al., 2003; Wilting et al., 2006)
and environmental conditions, vehicular traffic, and unworkable substrates validate
or invalidate a survey (Silveira et al., 2003; Henke and Knowlton, 2005).
Vocalizations can potentially be used to indicate the presence of the species
in an area (DeMatteo et al., 2004; Bauer, 2007) and sometimes can be used as an
estimate or index of relative animal abundance for social carnivores that utilize
long-range vocalizations (roars, howls, or whoops) to communicate (Gittleman et
al., 2001). They can potentially be used to indicate presence of the species in an
area (DeMatteo et al., 2004). Low response of animals to calls leads to non-
detections which results in severe underestimations of the population size
(DeMatteo et al., 2004; Kiffner et al., 2007). Spotlight surveys are a cost effective
method typically used for assessing the relative abundance of nocturnal animals.
Spotlight counts can be used to estimate population size (Henke and Knowlton,
2005). Factors which Influence animal activity might also influence counts (Henke
and Knowlton, 2005). Spotlight counts do not work well in areas containing low
densities of carnivores (Gittleman et al., 2001). In prey biomass method, both prey
and carnivore densities are measured and then compared to estimate the carnivore
abundance. Karanth et al. (2004) proposed a mechanistic model that predicts tiger
density as a function of prey density. McCarthy et al. (2008) used ungulate surveys
to estimate ungulate biomass and the potential density of snow leopards
supportable by that biomass. Sampling and detectability are two issues that
frequently present problem in macro ecological studies of animal populations.
Depredation surveys can also be used to estimate carnivore distribution but it needs
a lot of care during collecting the predation reports otherwise data will be severely
biased (Linnell et al., 1998; Gittleman et al., 2001).
DNA analysis techniques appear to provide an accurate, less costly and less
invasive alternative to population estimates derived from intensive capture and
radio-collaring efforts (Pool et al., 2001). DNA is extracted from hairs (Pool et al.,
2001; Mowat and Paetkau, 2002; Proctor et al., 2005; Long et al., 2007) and scat or
feces (Gompper et al., 2006; McCarthy et al., 2008). Extracted DNA is then
analyzed (Mowat and Paetkau, 2002). This technique may solve the problems of
misidentification and identification of individual animals collected and can also be
used to estimate population size (Gittleman et al., 2001). This allows both the
determination of sex and individual identity. One problem with this technique is
that extraction of DNA analysis may be failed (Long et al., 2007). Transportation
of samples to lab is a very big issue to this technique (McCarthy et al., 2008).
One of the modern techniques to study the large carnivore animals is
camera trapping (Wang and Macdonald, 2009). Active and passive are two sensor
systems available for camera trapping. Passive camera systems have wider zones of
detection than active systems (Swann et al., 2004; Goosem, 2005). Where aerial
resighting is difficult, camera-traps can also be used to provide recapture
observations (Linnell et al., 1998). It provides data that are difficult to obtain using
other methods. A permanent photographic record is available for examination by
other researchers (Gittleman et al., 2001). Camera trapping also have some
problems like initial cost (Silveira et al., 2003), theft or damage of cameras
(Gompper et al., 2006), shortage of camera sites, false triggers, failure to
photograph and camera or sensor failure (Swann et al., 2004; Long et al., 2007;
Kauffman et al., 2007). Camera-trapping of snow leopards, although in its infancy,
has had initial success as well (McCarthy et al., 2008). Capture-mark-recapture can
provide relatively accurate estimates of population size if sample sizes are
adequate, data collection techniques are unbiased, and the basic assumptions for the
population estimator are not violated (Linnell et al., 1998; Gittleman et al., 2001).
It does provide a reliable estimate of population size for many carnivore species. A
disadvantage of this technique is the lack of knowledge of what proportion of the
population was missed or not captured, moreover mark-recapture is fairly time
consuming, labor intensive, and costly (Gittleman et al., 2001).
Snow leopard and some other felids can be individually identified from
their unique pelage so, it is possible to photographically ‘‘capture’’ and
‘‘recapture’’ them on one or more sampling occasions. Most reliable method which
tells the exact number of individuals of a population is total count. While the
opportunity to directly observe carnivores may be considered rare, there are certain
species living in national parks or reserves with open habitats that allow for direct
observation and identification of all individuals (Gittleman et al., 2001) in the study
area. Total counts, based on individual recognition, are time intensive and
applicable in a very limited environment (Kiffner et al., 2007).
Population estimates of snow leopard have mainly been relied on
interviews, questionnaire surveys and sign surveys (Hussain, 2003; Mishra et al.,
2006; Ale et al., 2007; McCarthy et al., 2008; Maheshwari et al., 2010).
Questionnaire surveys provide baseline data about the presence or absence of snow
leopard in an area. Based on presence absence information sign surveys are done in
an area to find the relevant distribution and even population estimation. Snow
leopard Trust has prepared SLIMS (Snow Leopard Information Management
System) which is a standardized protocol for snow leopard sign survey (Jackson
and Hunter, 1996). SLIMS is used most of the snow leopard range. Most recently
camera trapping technique has been adapted in most of the countries to study the
population of the snow leopard. Camera-trapping of snow leopards, although in its
infancy, has had initial success as well (Jackson et al., 2005; McCarthy et al., 2008;
Subbotin and Istomov, 2009). A detailed survey of the past literature imposes an
urgent need to conduct updated field surveys using a standardized protocol such as
SLIMS (Snow Leopard Information Management System). If conservationists are
to ensure that populations of large predators like the snow leopard persist, they
need to know far more details about each species’ distributional pattern and
population trends over manageable time periods (McCarthy and Chaperon, 2003).

MATERIALS AND METHODS
3.1. STUDY AREA
The present study focused snow leopard (Uncia uncia) inhabiting Laspur
valley (Fig. 3.1), in Chitral district, NWFP. Laspur valley is situated in Mastuj sub-
division at a distance of about 115km in north-east of Chitral town. It lies at 34o
45/-36o 13/ north latitude and 72o 09/-72o 31/ east longitude and spreads over an area
of approximately 1393.6km2. It has Mastuj town in the north and Dir and Swat
Kohistan in the south, Gilgit in the east, Golen Gol in the west. The main nullahs or
sub valleys are Shandur Gol, Bashqar Gol, Rezhun Gol, Phargram Gol and Shachu
Gol, which drain into Laspur River. The altitude ranges between 2400 meter at
Onshot and 6210 meter at Ghochar sar (MACP, 2001). Total population of Laspur
valley is nearly 12,000 individuals and number of households is more than 2,000.
Main villages of the valley are Unchut, Shahi Das, Gasht, Herchin, Raman (Porth),
Brok, Balim and Sor Laspur. Major ethnic groups are; Baramay, Bujukay, Ukilay
(Wazirbagay), Doshay, Kalamay, Zonday, Badoray, Syed, Doranay and Donzay.
Laspur valley lies out of the monsoon rains area in arid temperate zone. The
precipitation in winter is in the form of snow while in summer rainfall occurs
occasionally. December and January are the coldest months during which entire
valley get covered with snow and mercury falls several degrees below freezing
point. The depth of snow varies with altitude and topography. Some of peaks are
covered with snow all the year round.
Fig.3.1 Map of Study Area (Laspur Valley).
The valley inhabits variety of wild animals and plants associated with arid
temperate and alpine zone. The prominent animal species include ibex, snow
leopard, brown bear, Indian wolf, Himalayan Lynx, Indian fox, Himalayan snow-
cock and Chukar. Migratory waterfowls also visit the valleys during their migration
seasons. Besides this, variety of resident waterfowls, raptors like coots, Kestrel,
Golden eagle, Black redstart, horned lark, Stone chat, Rock bunting and Rosefinch
are also found in the valley. The dominant plant species of the valley are Juniper
(Juniperrus macropoda and Juniperus communis). Sea buck thorn, Birch
(Betulautilis), Salix spp., Tamarix spp. Rosa webbiana, Ephedra spp. and Artimisia
spp (MACP, 2001). Agriculture and livestock rearing is the main source of
livelihood of the inhabitants of the valley. Some people are serving in the
government departments, NGOs and also work as daily laborer.
3.2. STUDY DESIGN
The present study employed the use of questionnaires and interviews with
local informants, to collect information about snow leopard. SLIMS sign surveys
and camera trapping technique were carried out to estimate the population of snow
leopard in the study area. The surveys were conducted in two phases;
3.2.1. Snow Leopard Surveys
3.2.1.1. Questionnaires, interviews, and sighting reports
One of the simplest methods to determine species distribution, and to gain a
subjective estimate of animal abundance, is to collect sighting evidence and general
impressions from various people in the field. Therefore, human-carnivore
interaction questionnaire surveys were carried out in Laspur valley, in July, 2009
and May-June, 2010, to collect information from local informants on snow
leopard’s presence and depredation for past five years (2005-2010). The sample
size for questionnaire surveys was calculated using Raosoft Sample Size Calculator
(http://www.raosoft.com/samplesize.html). The calculator provided recommended
minimum sample size at 30, by setting parameters at: Confidence level = 90%,
Margin of error = 15%, population size (total no. of households) = 2000.
We collected data of 59 households from Raman, Balim and Sor Laspur
villages of the Laspur valley. Head of a household or an adult person was
interviewed to gather information about his livestock, depredation by carnivores,
sighting of carnivores and perception about snow leopard and other carnivores. In
case of sighting of snow leopard, it was further confirmed by asking general and
specific questions about snow leopard appearance. Extreme care was taken during
interviews to avoid biases in the data but it was very difficult to test the honesty of
a person about his statements.
Questionnaires, interviews, and sighting reports were used to determine the
presence-absence of snow leopard and human-carnivores conflict in the study area.
3.2.1.2. SLIMS surveys
Snow Leopard Information Management System (SLIMS) second order
survey (Jackson and Hunter, 1996) was used to estimate snow leopard density,
status of prey species and habitat use in the study area. SLIMS is considered as a
Fig. 3.2 Interview with a local person in Laspur valley
Fig. 3.3 Searching Snow Leopard sign during SLIMS surveys in Bashqar Gol 2010.
comprehensive computerized database on snow leopard populations, protected
areas and key habitat attributes across their entire range. SLIMS surveys are based
on the tallying of signs such as scrapes, pugmarks, feces, rock scents and claw rake
found along fixed transects ranging from 0.3 to several kilometers in length and 10
meter wide. The present study was done in collaboration with the Snow Leopard
Trust (SLT) and World Wide Fund for nature, Pakistan (WWF-P) field staff having
vast experience of snow leopard surveys and snow leopard signs identification.
Transects were placed along routes most likely to be traveled by snow
leopards and data was recorded and decoded as per SLIMS protocols (Jackson and
Hunter, 1996). At starting point of each transect, information like GPS position,
location, date, observer name and starting elevation were filled out on transect
survey forms. Transects were walked slowly searching the signs of snow leopard
up to 5 meter distance of either side of transect rout. Whenever a sign was found,
its distance along transect from the starting point, site number (a site is a place with
snow leopard sign covering an area no greater than 5 meters in length), number and
kind (pugmark, scrape, feces or scent mark) of sign present at each site and age of
each sign item was recorded. All distinguished signs in five meters distance were
assigned to same site. Age of each sign item was determined by its freshness
following description provided by Jackson and Hunter (1996); Age Class 0 = very
old, Age Class 1 = old, Age Class 2 = fresh and Age Class 3/4 = very fresh.
Signs from other predator were also recorded. At the ending point,
elevation, total distance walked and GPS position were noted. Information about
dominant topography of transect, primary habitat type, grazing status, ruggedness
and overall aspect of the transect were also recorded.
Transects were plotted by randomly selected feasible landforms where snow
leopards sign was likely to be found, such as ridgelines, cliff bases, river bluffs
(Jackson and Hunter, 1996; McCarthy, 2000). Transects were kept short (minimum
and maximum lengths of transect were 0.256km and 1.168km respectively) and run
along landform edges.
First of all, SLIMS sign transect surveys were conducted on one side of
Bashqar Gol in the second week of August, 2009. A river (Laspur river) divides the
area into two parts. Nine transects were laid. Major topographic features of the site
were ridgeline, cliff base and hillside. The minimum and maximum elevation noted
during the transect walk were 3249m and 4174m. Total length of all transects for
this survey site was 8.045km.
In the last week of May, 2010, SLIMS surveys were carried out in
Phargram Gol. Eight transects were walked for snow leopard signs. Transect were
laid in snow leopard potential sites like ridgeline, cliff base and hillside. The
minimum and maximum elevations were 3416m and 4043m respectively. In this
site total length of all transects was 4.846km.
In Bashqar Gol, SLIMS surveys were conducted second time in first week
of June, 2010 but this time survey site was at the opposite side of the site which
was surveyed in 2009. Eight transects were searched for snow leopard signs on
ridgeline, cliff base and hillside. The minimum and maximum elevation noted
during the transect walk were 3496m and 3981m respectively. Mean length of the
transects was 0.626km while total 5.011km distance was covered during transect
walk.
SLIMS sign transect surveys were conducted in Shandur during the third
week of June, 2010. Sixteen transects were laid considering ridgeline, cliff base and
hillside as major topographic features. The minimum and maximum elevation
noted during the transect walk were 3477m and 4501m respectively. Total transects
length was 9.165km.
Snow Leopard Survey and Conservation Hand book by Jackson and Hunter
(1996) was followed to analyze the distribution and abundance of snow leopard and
its prey base. According to them, it is assumed that the greater the density of sign,
the greater the relative abundance of snow leopard within a particular area. Snow
leopard numbers were guessed by computing the average sign frequencies for each
survey block, and classifying these according to the relative density classes of high
(more than 20 items per kilometer), medium (5 to 20 items per kilometer), and low
(less than 5 items per kilometer). High density sign sites could be indicative of
snow leopard densities as high as 10 or more cats per 100km2, while low density
sites may have only one or two cats in the same area.
3.2.1.3. Camera trap
Camera trapping methods were adapted from Jackson et al. (2005). Twenty
passive infrared cameras (CamTrakker™ Ranger, Wattkinsville, GA, USA) were
set in BashqarGol for 30 days from May 24, 2010 to June 22, 2010. The system is a
waterproof unit housing a 35mm camera, requiring four AA-1.5v lithium, and one
6v rechargeable lead acid batteries. The system is triggered when a moving animal
with a higher body temperature than the ambient temperature crosses the camera
detection zone. This system can be set for a 20 second up to a 45 minute delay
between pictures, and also set for day, night, or continuous operation. The delay
function limits the number of pictures taken when a non-target species trips the
system or remains in front of the camera for a period of time, reducing the chance
that a complete roll of film could be taken of a single, non-target species.
To maximize the possibility of capture success, camera traps were placed
strategically along possible traveling routes of carnivores, including sharp
ridgelines, near scrapes, cliff bases, rock faces, and along game trails. Cameras
were either faced directly up or down to anticipate travel in order to obtain close-up
photographs of the face for quick identification or oriented at angles from animal’s
anticipated travel path to capture simultaneous photographs of either side of the
animal’s body. Cameras were generally faced towards the north or south to avoid
erroneous pictures caused by direct sunlight. Cameras were placed in rock piles or
on metal stakes approximately 45-50cm above the ground. The camera sensors
were placed in such a position that there was no vegetation in the foreground that
could trigger the camera. Cameras and infrared sensors were concealed and
covered (Jackson et al., 2006) to protect against poor weather conditions. After
setting, camera traps were checked every week and batteries and films (if needed)
were replaced. The number of trap days was calculated for each camera location
from the time of mounting to the time of retrieval (Johnson et al., 2006).
Fig. 3.4 Setting a camera in Bashqar Gol in May-June 2010.
Fig 3.5 A camera trap in Bashqar Gol (CamTrakker™ Ranger, Wattkinsville,
GA, USA).
Trap cameras were distributed across the core zone of the study area and all
the trap stations were spaced about one kilometer apart. A large separation between
cameras might allow animals with small home ranges to avoid the cameras. At the
end of the trapping period, cameras were retrieved and films were processed.
Individual animals were identified on the basis of their distinct pelage
patterns according to the guidelines provided by Jackson et al. (2006) for
identification of animal from photographs. Photo rate was calculated by dividing
number of individual photo events by total number of trap nights. Criteria of
McCarthy et al. (2008) was used to consider a photo or set of photo to a single
photo event.
Due to low density of cat in the area capture rate was very low and capture-
mark-recapture model could not be applied. For snow leopard extremely low
capture rates and associated high standard errors suggest that under some
circumstances this method may be vulnerable to logistical constraints (McCarthy et
al., 2008). Jackson et al. (2006) suggested a larger sample size to get an accurate
estimate of population density and abundance based on capture-mark-recapture
models.
3.2.2. Ungulate Surveys
3.2.2.1. Fixed–point counts
Fixed point counts were conducted using the methods detailed by Jackson
and Hunter (1996) to assess the population of major prey species (Himalayan Ibex)
of snow leopard in the study area. Five different sites; Bashqar Gol, Rezhun Gol,
Phargram Gol, Shachu Gol/ Shahdas Gol, and Shandur were selected for ibex
population counts. Counting was undertaken from high vantage points by using
Bushnell binocular-10x and spotting scope (15-45x) to locate maximum animals.
Minimum two observers were present at a point to record the observations. Each
observation site was set depending upon the visibility and topography of area.
Surveys were carried out in early morning and late afternoon, as these are the most
active periods of ungulates in a day and sun direction makes them visible
(McCarthy et al., 2008). Peak rut season; last week of December was selected for
survey to get maximum information. Sources of biases were tried to be minimize
by following Jackson and Hunter (1996). Data was recorded using standard criteria
and age classes (Jackson and Hunter, 1996). Overall population status in each site
and the whole study area was calculated from the data recorded.
3.3. STATISTICAL ANALYSIS
The results obtained regarding the surveys of ungulates in the study area
were analyzed and interpreted using chi square test.

RESULTS
4.1. HUMAN PERCEPTIONS ABOUT SNOW LEOPARD
Total 59 individuals were randomly selected from three villages for
questionnaire survey in Laspur valley. About 34% individuals confirmed the
sighting of snow leopard in the area. Some of them also reported sighting of cubs
with snow leopard, which indicates reproductive activity of the animal in the area.
Community perception about snow leopard was divided; however 58%,
respondents wanted to increase the population, 36% people wanted to stabilize the
existing population, and only 6% people were in favor of reducing the population.
No respondent urged to eliminate cat from the area.
Snow leopard was also considered as less dangerous animal as compared to
wolf and lynx. Communities were asked to rank four carnivore species (snow
leopard, wolf, lynx and brown bear) according to their perceived danger. Majority
of communities (58%) considered wolf as most dangerous (Fig. 4.1), lynx was
considered second most dangerous. Snow leopard was perceived as less dangerous
from the former two species, but more dangerous than brown bears.

were conducted in three different sites of the valley which were indicated as most
potential sites by local peoples and herders. One of these three sites was bifurcated
by a permanent river so it was surveyed twice on both sides of the river, once in
2009 and second time in 2010. Sign frequencies were very low in all sites which
resulted in failure of finding any sign in one of the surveyed site; Phargram Gol,
which was also indicated a potential site. In this site it was also came to know about
killing of two snow leopards few years back in reaction to massive depredation in
the area.
A total of 41 transects were placed in the study area (in three study blocks)
having 27.067km in length with 660m mean transect length. Mean sites per transect
were 0.83 while total 34 sites were found. Maximum sites per transect were 6 while
there was no site recorded in some transects also. Sixty-nine signs were recorded in
total 34 sites. Average sign per km were 2.55, showing low density of the cat in the
survey area (Table 4.1). Among the signs, pugmark frequency was highest
(65.22%) followed by feces (18.84%), and scrapes (15.94%) (Fig. 4.2). Similarly,
the signs recorded were both fresh and old and fell into the four age classes; Age
Class 0 (41.79%), Age Class 1 (17.91%), Age Class 2 (1.49%) and Age Class 3
(38.81%) (Fig. 4.3). The sign density was not uniform among different study sites.
Higher sign encounter rate was found in Bashqar Gol, during surveys in 2010, with
5.99 mean signs/km while lowest sign density was found in Phargram Gol with no
sign item (Table 4.2). Based on sign surveys, the population density of 1-2 snow
leopards was estimated in the Laspur valley following the criteria of Jackson and
Hunter (1996). Details of SLIMS finding in each study block are given below:

4.2.1.1. SLIMS survey in Bashqar Gol 2009
Seventeen sites containing 29 signs items with 19 pugmarks (65.52%), 7
scrapes (24.14%), and 3 scats (10.34%) were reckoned while searching for Snow
leopard’s signs in 9 transects. Mean sign per site was 1.89 sites per kilometer. Sign
density of all transects for this survey site was 3.6 signs per kilometer indicating
low density of snow leopard in the area (Table 4.3). Signs were either old or very
old i.e. 55.56% signs were of Age Class 0 and 44.44% signs fell into the category
of Age Class 1.
4.2.1.2. SLIMS Survey in Bashqar Gol 2010
Snow leopard signs were searched in 8 transect and total of 30 signs were
documented consisting of 26 pugmarks (86.67%), 1 scrapes (3.33%), and 3 scats
(10.00%) in 10 sites. Mean sign site was 1.25 per kilometer. Sign density of all
transects for this survey site was 5.99 signs per kilometer indicating low density of
snow leopard in the area (Table 4.4). Most of the signs were fresh but some were
very old and they fell in three categories i.e.; Age Class 0 (10.00%), Age Class 2
(3.33%) and Age Class 3 (86.67%).
4.2.1.3. SLIMS survey in Phargram Gol 2010
A total of eight transect were searched but no sign of snow leopard was
found at all (Table 4.2).

4.2.1.4. SLIMS in Shandur 2010
In Shandur 16 transect were walked and 7 sites containing 10 signs items
with three scrapes (30.00%) and seven scats (70.00%) were reckoned. Mean sign
site was 0.44 sites per kilometer. Mean sign per kilometer was 1.09 reflecting very
low density of snow leopard in the area (Table 4.5). All signs found were old
belonging to Age Class 0.
4.2.2. Camera Trapping
Twenty passive infrared cameras (CamTrakker™ Ranger, Wattkinsville,
GA, USA) were set in Bashqar Gol for 30 days from May 24, to June 23, 2010. We
deployed cameras over a period of 30 days in the study areas at 20 stations (Table
4.6). Transferring equipment between different sites was time consuming and it
prolonged the study period. Number of trap-nights was 640 and was a function of
the number of camera stations and number of days they remained operable. Capture
rate (no. of different identifiable individuals captured/100 trap-nights) was low
(0.16).
Three snow leopard photos were captured but they were multiple pictures of
the same animal in the same capture period and that is why only 1 capture event
was recorded, which limited the results of camera trapping to a minimum
population of one.
Total 38 photos were taken in all 20 cameras. Among them, majority were
of livestock (53 %), followed by snow cock (24 %) and Ibex (11 %). Only seven
cameras took photos of animals while rest of 13 remained inactive (Table 4.6). A

big proportion of photos were due to false triggering of cameras and there was
nothing to see except scenery.
Camera trapping did not produce data sufficient to test capture-mark-
recapture model to get an accurate estimate in whole area. It only confirms that at
least one snow leopard is present in the study area. Due to low cat density in the
area and low capture rate, we could only get one photo event and it restricted our
results because data was not sufficient.
4.3. POPULATION OF WILD PREY
Point vantage counts for population counting of ungulates in the study area
revealed a population of 174 animals; with breakdown among study blocks as 73 in
BashqarGol, 11 in RezhunGol, 30 in PhargramGol, 29 in ShachuGol/ ShahdasGol,
and 31 in Shandur, respectively (Fig. 4.7). Lambs constituted a dominant part of the
population (39.7%); while females and males were 33.3% and 27%, respectively.
However, this difference in female to male ratio was not significantly different
from 1:1 (χ²=0.227, P=0.634).
4.4. HUMAN-CARNIVORE CONFLICTS
There were 23.64 ± 9.79 (SD) animals owned by a household on average in
the valley. Goat constituted 36%, sheep 36% and cattle were 22% while yaks and
donkey were 6% of the total livestock holdings. The total livestock population of
the valley was estimated to be 48,000 in 7 villages of the Laspur Valley.

A total of 199 depredation cases to three carnivore species (snow leopard,
wolf and lynx) were reported in five years, affecting 38 households (64% of
surveyed sample). Among these damages, 37% were goat, 43% sheep, 13% were
cattle, and 7% were other animals. Total loss in the entire valley (2000 households)
in five year was estimated to be 6800 animals. It gives an annual loss of 1360
animals; 503 goats, 585 sheep, 177 cattle and 95 other livestock. The annual loss to
predation per household is estimated to be 0.68 animals, which equates to
economic loss of PKR 5,800 (US$ 70) per household, assuming average market
values of 4500, 3500, 25000 for goat, sheep and cattle, respectively.
Looking at the predation losses by type of predator, wolf contributed
maximum damage, followed by snow leopard and lynx (Fig. 4.16). No losses were
reported to brown bears. The snow leopard contributed losses were 25% (Fig.
4.17), which means that economic loss imparted by snow leopard was PKR 1450
(25% of total estimated value).
Almost all predation cases (98%) were occurred in pasture while free
grazing while only in a few (2%) cases depredation occurred because of having no
proper care to livestock. Both adults and young ones were killed but the proportion
of adults (94%) was much more than young ones (6%).
By using multiple census method to determine the status of snow leopard, a
minimum population of 1-2 snow leopards was estimated in the Laspur Valley of
Chitral district. Population of ibex (snow leopard primary prey) also indicated the
presence of at least one snow leopard in the area. Human-carnivore conflict surveys
showed that snow leopard is not considered as much dangerous as some other
carnivore like wolf and lynx.

DISCUSSION
Laspur valley is a remote area of district Chitral bordering Gilgit-Baltistan
on one side and district Swat of Khyber Pakhtunkhwa on the other side. Total area
of the valley is about 1393.6km2. No density estimates were available for snow
leopard and status of this endangered species was unknown in the area. This study
provided first ever information about the population status of snow leopard in
Laspur valley using standardized sign surveys and camera trapping.
Human-carnivore interaction surveys were conducted in three villages of
the valley in 2009 and 2010 which indicated the presence of snow leopard in the
area. About 34% respondents confirmed the sighting of snow leopard in the area.
Though this sighting rate was quite lower than the reported rate from Baltistan
(80%, Hussain, 2003), it provided basis for exploring occurrence of snow leopard
in the valley through standardized survey.
In 41 SLIMS transects, sign density was estimated at 2.5 per km2, which is
lower than densities documented from other areas of the Chitral District. Sign
densities recorded from the Torkhow Valley (Din and Nawaz, 2010) and Chitral
Gol National Park (SLT, 2008) is 5.8 per km2. Densities reported from other parts
of snow leopard range are even higher. McCarthy et al. (2008) found an average
sign/km as16.4, 40.7 and 94.6, respectively in three different sites in Kyrgyzstan
and China. Khatiwada et al. (2007) found 6.1 signs per km in Nepal. Consulting
SLIMS guidelines (Jackson and Hunter, 1996) a population of 1-2 individuals was
estimated in the Laspur valley. Camera trapping in a potentially good habitat for
snow leopards; Bashqar Gol yielded three photographs of the same snow leopard.
Thus, camera trapping results supported sign survey findings and confirmed a
population of at least 1 snow leopard in the area. However camera trapping data
was not sufficient enough to allow testing any modeling for population estimation.
It was challenging to carry out one month camera trapping in Bashqar Gol
for multiple factors. Two big factors were heavy snow fall and land sliding which
restricted the movement and access to many points. Snow falling continued in most
of our study time and it kept temperature very low which also reduced batteries life
of camera and it increased our visits to the camera stations to check and replace
batteries. Factor of camera security could not be ignored because of huge number
of livestock herders in the area. Topography of the area was also quite different and
sometimes it was confusing to select a suitable place for camera trap. Despite of all
preventions we found some of our camera damaged due to unknown reasons.
However, all the film rolls were recovered and developed successfully.
Sign densities were low in all sites. A reason for low sign frequency was
movement of livestock, as the area become accessible for tracking, local people
immediately used to shift their livestock to the pasture. Poor weather might also
destroy signs.
Due to all these factors camera trapping did not produce substantial results
in this study, which would helpful to find the population status of species in the
area. Based on camera trapping at least one snow leopard is confirmed in the study
area. Population estimates are based on sign surveys however, camera trapping was
helpful to confirm the presence of snow leopard in the area. We could not apply
Capture-mark-recapture model to our results of camera trapping because of very
low cat density and only one photo event. Capture-mark-recapture would be
applied if photo events were more than one (McCarthy et al., 2008).
Ungulate surveys supported findings of sign surveys and camera trapping
(Jackson et al., 2006). Estimated population of ibex (174) also supports presence of
snow leopard in the valley, as distribution of predator is generally influenced by the
prey population (Karanth et al., 2004). However, these counts are based on single
observation and short term so that population of ungulates might exceed from these
calculations. Higher population was found in Bashqar Gol where snow leopard
signs encounter rate was also higher and this was the same site where a snow
leopard was photographed. A relatively higher ibex count (429 individuals) was
made in Torkhow valley, which is supporting a population of 2-3 snow leopards
(Din and Nawaz, 2010).
Total 199 depredation cases were reported in five years with an annual loss
rate of 0.68 animals per household. Wolf (44%) was responsible for most
predations followed by snow leopard (25%) and lynx (21%). Sheep (43%) was
most predated followed by goat (37%). Expected economic loss per household of
one village (330 households) per year is about PKR 5800 (70 $USD) while total
economic loss in whole village in one year is expected to be PKR 1,914,000
(22,786 $USD). Namgail et al. (2007) assessed the intensity of livestock
depredation by snow leopard and other large carnivores in India and reported 295
animals in 2.5 years with an annual loss rate of 2.9% of their livestock holdings. In
most of the cases the predator was wolf followed by snow leopard and lynx. They
estimated total annual loss of about $USD 12,120 in three villages and $USD 190
per household per year.
Snow leopard is one of the poorly studied species in Pakistan. Population
estimates of snow leopard are not based on rigorous data. Most of its range is not
surveyed yet by using standardized methods and reliable technique like camera
trapping. Snow leopard population in Pakistan is generally speculative, thus their
reliability is always questioned. Questionnaires and interviews are based on
personal views and might be misleading as well. In this study we used multiple
methods and similar findings of all enhance confidence on results. The
questionnaire surveys and interviews confirmed sighting and depredations of snow
leopard in the area. Sign surveys further confirmed presence, and along with
camera trapping provided minimum estimate of the population. It is however,
recommended that molecular techniques might be used to evaluate findings of the
present study.
Livestock depredation by snow leopard and other carnivores results in the
retaliatory killing of carnivore species. This is a major issue faced by
conservationist addressing the conservation programs of large carnivore species
(Mishra et al., 2003). Economic conditions of the people of the study area poor.
Agriculture and livestock rearing is the only source of income for most of the
households. Predation losses thus pose a serious economic threat to the community,
and also make conservation efforts very difficult. Snow leopard is worldwide under
threats of retaliatory killing. Community based conservation programs that could
address grievances raised by predations would help conserve this endangered cat by
changing public attitudes (Mishra et al., 2003). For example, Snow Leopard
Enterprise program in Mongolia reduced dependence on livestock and helped
change people attitude towards predators. This ultimately eliminated snow leopard
poaching in the area (Mishra et al., 2003). As it was revealed from the present
study that population of snow leopard is very low in the area so, conservation
programs must be initiated to protect the species.
SUMMARY
Snow leopard (Uncia uncia) is a solitary felid of cryptic nature and
occupies a habitat that makes very difficult to enumerate it. Most of the information
available on snow leopard status and distribution in Pakistan is largely based on
anecdotal evidence. So, the conservation and management of species may be
compromised due to the lack of reliable information. The species is found in
northern parts of the country. Although a few studies are available regarding snow
leopard in Pakistan but no detailed scientific studies have been carried out yet so
far along most of its range in the country. Thus, there was an urgent need of
conducting a scientific investigation on snow leopard to get accurate information
about its current status. The present study had been designed to assess its
population status in Laspur Valley, district Chitral (Khyber Pakhtunkhwa). Total
area of Laspur valley is approximately 1393.6km2.
The study employed the use of questionnaires, interviews from local
informants, SLIMS (Snow Leopard Information Management System) survey and
camera trapping to estimate its population in the study area. The basic aim of the
study was to measure the status of snow leopard in the area and its conflict with
local people. During questionnaire surveys 20 out of 59 households confirmed the
sighting of snow leopard in the study area. Community perception about snow
leopard was also good and most of the people either wanted to increase (58%) or
stabilize (36%) the population of snow leopard. Nobody gave snow leopard to rank
of very dangerous animal, majority (58%) ranked it as low danger to community as
compared to wolf (Rank I= 58%) and lynx (Rank I= 42%).
Results of SLIMS survey estimated 1-2 snow leopard in the area with an
average 2.55 signs per km in total 27.1 km area in three different blocks; Bashqar
Gol, Phargram Gol and Shandur. Furthermore, the findings of questionnaires and
SLIMS sign surveys were confirmed by camera trapping with photos of a Snow
leopards. Camera trapping results could not be tested by capture-mark-recapture
model because this model works for large sample size but on the basis of camera
trapping at least on snow leopard in the area is confirmed.
Population of ungulates was counted by point vantage counts and it
revealed the population of 174 ibex in Laspur valley. This is a justified number of
ungulates to support the population of one or two snow leopard in the area. Human-
Carnivore conflict was also measured by comparing livestock number and damages
to carnivores. Total number of livestock in all 8 villages was calculated at nearly
48000 animals while nearly 6800 animals were lost to depredation in five years
from 2005-2010. Total 199 losses were claimed in 59 households, selected for
interviews, during last five year with an annual loss to predation per household is
estimated to be 0.68 animals. An economic loss of PKR 5,800 (US$ 70) per
household was calculated in the valley. Wolf (44% predation cases) dominated the
predation followed by snow leopard (25%) and lynx (21%). No loss was reported
to brown bears. The snow leopard contributed losses were 25%.
