"Yes, that's right! I'm an Arabian leopard. But why have you entered my realm?" |
Activities
The
leopard emerges from beneath an overhanging rock in mountains of Dhofar in southern
Oman. Its pale coat blends in perfectly with the dusty background on the rugged
range of peaks known as Jabal Samhan. Positioning itself in front of a vertical
rock face, the leopard lifts its tail stiffly and sprays the rock with a
pungent calling card. Then it then sniffs the boulders for evidence of other
visitors and slinks off down the trail.
It's
hard to absorb the significance of what we've just seen, and perhaps even
harder to picture the Arabia of ancient times when sights like this were commonplace. The second-century bc Greek geographer and historian Agatharchides wrote, “The pasturage ... supports
flocks and herds of all sorts. Crowds of lions, wolves and leopards gather from
the desert, [and] against these the herdsmen are compelled to fight day and
night in defense of their flocks.”
Today,
it's very different. The lions disappeared centuries ago, and the wolves are
few in number. But—somehow—the leopard managed to linger. Jabal Samhan, a
super-arid network of rocky plateaus and nearly impenetrable gullies
where June shade temperatures regularly top 46 degrees Centigrade (115°F), is
one of the last lairs of the elusive Arabian leopard.
Arabian Leopard Factfile
Scientific name: Panthera pardus nimr
Head and Body Length: 1.3 meters (4' 4")
Weight: Male 30 kilograms (66 lbs), female 20 kilograms (44 lbs)
Habitat: Mountainous areas with forest/scrub, preferably with permanent water sources
Prey: Gazelle, ibex, hyrax
Threats: Persecution, poaching, habitat loss, prey depletion
Behavior: Generally thought to be nocturnal, but this is now in question. Marks territory using scrapes, scent marking and defecation.
Unlike
Agatharchides, however, I still haven't seen an Arabian leopard in the wild.
Very few people have. What we viewed this morning was an image on a video
screen. The Arabian leopard is one of the rarest animals on the planet. Until
recently, no one knew for sure if the leopard still lived in the Dhofar
mountains. The only visible evidence of its continued survival had been the
occasional goat seized from a settlement on the edge of the territory, often followed
by the discovery of a leopard carcass bearing a lethal gunshot wound.
For
humans, the odds of a chance encounter with a leopard are almost zero. Not only
is the stealthy cat wary of humans, its coat is such that it blends in almost
seamlessly with its environment.
The
International Union for Conservation of Nature has classified the Arabian
leopard as “critically endangered,” meaning it faces an extremely high risk of
extinction. In 1976, Oman granted it special protection and in 1997 further
safeguards were enacted when an area of 4500 square kilometers (1740 sq mi)
comprising Jabal Samhan was declared a protected area. But, it was unclear
whether, by that time, it already had edged too far toward extinction. Unclear,
that is, until one man took up the challenge to find and photograph the animals.

"Steady there—we're almost finished!" says a researcher as he holds the head of a sedated leopard, fitted with a GPS collar. To trap this leopard and three others in 2001, the researchers use goats as bait. |
“It
started in 1989,” explains wildlife cameraman David Willis. “I was interested
in filming ibex and heard that in Jabal Samhan you could see herds of up to 40
animals. One night while camping we heard a leopard calling. I'd heard them
before in Africa but didn't think it was possible to encounter them in Oman.
Then, over the next few days, we saw the tracks.”
Willis
decided to try to photograph the animals. He used a homemade system of remote
35-mm cameras, installed in locations where he had found footprints, “scrapes”
made by pawing the ground and other leopard markings. Each camera was linked to
a carefully disguised pressure plate—a plywood platform that would trigger the
shutter when it was stepped on. Willis left the setup in the mountains and then
traveled some 1000 kilometers (620 mi) back to his home in Muscat, the capital
of Oman.
“When I recovered the film three months later and saw that 15 frames had been
shot, I assumed they would be pictures of dogs and donkeys—maybe the occasional
camel,” Willis explains. But when he had the film developed that he saw, among
the dogs and donkeys, eight pictures of an animal few had ever seen in the
wild: likely the first-ever images of the Arabian leopard.
Research Methods
Oman's Arabian Leopard Survey uses a variety of techniques to learn more about its subject:
Ground surveys: Researchers comb the area for signs of leopard presence. These include territorial scrapes, scats or urine, scent sprays and evidence of kills.
Camera trapping: A weatherproofed camera is positioned next to routes known to be used by leopards. The camera may be triggered either by a pressure plate or an infrared beam. Researchers can use the resulting images to identify individual leopards.
Satellite tagging: Leopards are trapped, sedated and fitted with collars carrying satellite tags. Although expensive, the collars can provide detailed information about the leopards' movements and behavior.
There's
no denying that the Arabian leopard is a magnificent beast. Its coat is a
creamy-buttermilk color, its rosettes (the technical name for the spots that
pepper its lean frame) an inky black. The combination makes it virtually
invisible in its rocky hideout. Although smaller than its African counterpart,
this is a powerful predator—though clearly not one averse to a little fun: One
series of shots shows a leopard in a variety of airborne poses, returning
repeatedly to bounce on the spring-loaded pressure plate.
After
hearing about Willis's work, Dr. Andrew Spalton, adviser for Conservation of
the Environment in Oman, immediately recognized its potential and the Arabian
Leopard Survey was born. “We suffered endless technical issues,” explains
Spalton. “Our equipment overheated, leopards scent-marked the cameras by
rubbing against them, donkeys knocked them over, and mice chewed through the
cables.” Even when the camera-traps worked, the results were less than
reliable. “Having mounted a major expedition to recover films and reset traps,
we could get entire films full of nothing but donkeys. From a total of 13
cameras, we might get one leopard image,” he says. Nonetheless, between 1997
and 2000, the team gathered a total of 251 photos of Arabian leopards.
To
count the number of leopards recorded on film, researchers used the shape and
pattern of the rosettes on each leopard's coat. These are unique to each animal,
rather like a human fingerprint. Analysis of the images revealed 17 individuals:
16 adults (nine females, five males and two of unknown sex) and, most exciting,
a cub. The results suggested a total population of around 50, confirmed that
the leopards were breeding and offered invaluable information about leopard
behavior.

"Believe me, saving the leopard will help your village and the area," says a Jabal Samhan Nature Reserve ranger. The goal is to persuade local residents that the benefits of keeping the leopards alive will outweigh the loss of livestock to the leopard. |
Leopards
are widely considered nocturnal animals. However, those in one of the three
monitoring areas were most active from six to nine in the morning and three to
seven in the evening. Spalton thinks that this could be due to the different
environmental conditions in this area, which includes a steep-sided gorge with
permanent water and plenty of shade.
But
a more important factor, he suggests, is the absence of human activity. Since
leopards avoid human contact, with none in the area, the leopard can adjust its
activities to suit environmental conditions.
In
2001, Spalton led the team on an even more ambitious project—satellite tagging.
Team members capture the animals and then sedate and fit each with a collar
carrying a small GPS device. The collars store data for three months and then
drop off. Despite some technical hitches, four collars have been recovered and
the data they contained reveal some astonishing information about the leopards'
movements. For example, some travel long distances. One covered 476 kilometers
(295 mi) in a 55-day period!
Such
distances are not difficult to explain. Data gathered by the survey team
suggest that male leopards in this area have an average annual home range of
180 square kilometers (70 sq mi), while leopards living in lush grasslands,
which support a higher concentration of prey, may have a range of 50 square
kilometers (19 sq mi) or less.
But
the leopard's need for food and the fact that it roams such a wide area have
brought it into conflict with another predator: humans—specifically, the
nomadic tribesmen of Jabal Samhan who keep camels in the hills. When the khareef,
the southwest monsoon, brings rains, the tribesmen bring their camels to the
lower pastures.
Hadi
al Hikmani, a member of a Jabal Samhan family, says, “In some ways my parents regarded the leopard as an enemy to be
feared, as it kills livestock. But if we heard the leopard calling when we sat
round our camp at night, everyone would get very excited. It was regarded as a
good omen. The older men said it would be a good year ahead.”

"Look. Here's a photo of one of our country's most prized treasures—the Arabian leopard." In Oman today, students learn that while leopards may at times be a nuisance, they are also an integral part of southern Oman's ecology. |
Today,
al Hikmani is employed full-time by the Arabian Leopard Survey. His job is to
help bridge the gap between the local population, many of whom still view the
leopard as a livestock killer, and the Omani government, which seeks to protect
an endangered predator. Spalton is keen to demonstrate that preserving the
leopard can bring economic benefits, partly through the introduction of
carefully controlled, low-impact tourism projects.
However,
as old conflicts are resolved, new ones are created. While the leopards need
huge territories to survive, development creeps ever closer in the form of new
roads, houses and hotels. The survey team has already noticed a decline in the
number of animals that have their pictures taken on camera-traps in one area.
What
does the future hold for the shadowy leopard of Oman's Jabal Samhan? “To keep
its place in the mountains, the leopard needs to find a place in people's
hearts and minds,” says Spalton. Having adapted its habits to survive the 2200
years since the time of Agatharchides, the leopard may be able to succeed in
making this further critical last leap.
If
it can't, then the only place the next generation will see this mysterious
mammal is on film.
