Wilpattu, Sri Lanka\u2019s oldest and largest national park, was once a warzone. The fighting between the Sri Lankan state and the militant separatist group Liberation Tigers of Tamil Eelam (LTTE) that began in the 1980s had spilled over into these wild lands.<\/p>\n

Wildlife researchers Anjali Watson and Andrew Kittle remember hearing stories from soldiers stationed in these forests. The men recalled nights when they would be jolted awake by the sound of landmines exploding in the pitch darkness, somewhere beyond the border of their camps. Nervously, they wondered whether guerillas had triggered the bombs, and if their enemies would soon close in on them.<\/p>\n

But the dawn would bring evidence of a different kind of victim. The remains of peacocks were found lying in heaps of shredded feathers; elephants lay with limbs blown off. \u201cA few leopards and bears were also shot because men who encountered them were afraid,\u201d Watson told me, explaining that the thick, thorny forests often swallowed any evidence.<\/p>\n

The park itself was off limits to the researchers during the conflict. But even after a ceasefire signed in 2002, it remained unsafe\u2014a mine claimed the lives of a jeep full of wildlife enthusiasts in 2006 and a year later, Wilpattu\u2019s park warden Wasantha Pushpananda was ambushed and killed by the LTTE while on an inspection tour with his team.<\/p>\n

<\/p>\n

It wasn\u2019t until the nearly 30-year-long war came to an end in 2009, and many landmines laboriously cleared, that Watson and Kittle were able to readily move about Wilpattu again. They are now publishing data from one of the most comprehensive studies of the leopard population in Wilpattu\u2014the first since the Smithsonian Institution did a more general survey in the late 1960s.<\/p>\n

A husband and wife team, Kittle and Watson head The Leopard Project at the Wilderness and Wildlife Conservation Trust (WWCT) in Sri Lanka. They have been studying leopards for over a decade and were responsible for gathering the data that put the native big cat on the International Union for Conservation of Nature\u2019s Red List of endangered species in 2008.<\/p>\n

\u201cBeing on the Red List influences both conservation and funding attention,\u201d Watson said, explaining that IUCN tracks the global status of various species. In Sri Lanka, the state\u2019s conservation programs had previously been focused overwhelmingly on the elephant, but the IUCN listing has driven a surge of interest in the leopard and its significance as an apex predator\u2014residing comfortably at the very top of the food chain on this island.<\/p>\n

Kittle, Watson and I meet in their small office, perched above a garage in central Colombo, the commercial capital of Sri Lanka. The two sit across from each other and share a desk, seeming to be seldom out of each other\u2019s company. Their rhythm has roots\u2014the two met in university and have since travelled widely, always working closely together as a team. When their children were born, they simply took the kids along to the field, something they continue to do. Little drawings by Ayla and Amara decorate an entire wall in their office.<\/p>\n

Watson said she and Kittle first knew they could make such a close partnership work when they were assigned to help reestablish a wild population of native primate species on an uninhabited island on the Panama Canal in the late 90s.<\/p>\n

\u201cThere was just the two of us, and a guard who spoke Spanish,\u201d Watson tells me, laughing. \u201cI spoke no Spanish, Andrew spoke some Spanish, and the only other contact we had was a boat coming in every Saturday to bring us provisions. We spent nearly two years there, and I thought if we could do this…\u201d<\/p>\n

Today, though their work still might take them far afield, Sri Lanka is home\u2014Watson said her heart is with this island because she grew up here. The duo are working toward establishing a comprehensive habitat use plan for the Sri Lankan leopard by 2020, including a population distribution map, and assessments of its habitats across the island. But tracking this predator has always presented a challenge.<\/p>\n

When Watson and Kittle first told me this, I was surprised. I have seen leopards in Yala National Park in southeast Sri Lanka, where the big cats draped themselves decoratively over high branches and rolled around on dusty trails as tourists watched. But Kittle explains that in Wilpattu, and pretty much everywhere else in the island nation,the Panthera pardus kotiya is notoriously shy.<\/p>\n

\u201cUsually cryptic carnivores like this are really difficult to spot,\u201d he said, adding that leopards manage to remain elusive despite existing in relatively high numbers in little pockets across the island.<\/p>\n

Now, in the Peak Wilderness Sanctuary in central Sri Lanka, where tea plantations abut dense forest, encounters between leopards and people are on the rise. As more and more wilderness is cleared, Kittle and Watson say leopards and other animals are increasingly moving around and even breeding in \u2018habitat mosaics\u2019, or heavily fragmented forested areas surrounded by a patchwork of farms, plantations and homesteads. As a result, villagers are reporting more leopards sightings.<\/p>\n

With one legendary exception\u2014in the 1920s, the \u2018maneater of Punanai\u2019 was a voracious killer\u2014Sri Lankan leopards are not maneaters.<\/p>\n

In Dickoya, people have escaped encounters with the animal with just some deep scratches. Watson and Kittle, increasingly called on to reassure nervous communities, use these incidents to help convince villagers that the leopards are likely as frightened of the people as the people are of them. Working closely with the management of sprawling tea estates, they are now trying to find ways to prevent humans from barging in on the leopards. But to do this, they first have to know where they will be.<\/p>\n

In the years that Watson and Kittle have been out in the field, they\u2019ve seen the tracking technology available evolve. In their earliest forays into the field, they would rely on sighting the animals directly and recording each encounter. Some of Yala\u2019s leopards, such as one who boasted bold spots in the shape of a \u2018W\u2019 on his forehead, were immediately recognizable, others could only be identified by closely examining photographs of the unique pattern of rosettes on their bodies.<\/p>\n

The couple would also rely on tracing Paw Impression Pads: sweeping leaf litter away from a likely spot, they would create a sandy clearing, then return to record pugmarks. This technique allowed them to set up TrailMasters, camera traps that ran on film, to monitor spots where there was a lot of leopard traffic.<\/p>\n

Watson and Kittle stuck with the technology up until 2012, before they switched to digital cameras. Film cameras could be cumbersome in the field, demanding hooking up wires and multiple components, but digital ones offered better battery life, were usually more weather resistant, and enabled them to get results faster and cover larger areas.<\/p>\n

Ironically, conservationists must often rely on technology developed for hunters, Kittle said, but at least there are hundreds of cameras to choose from. Currently, they use Scoutguard SG565F cameras which have an incandescent flash (old style, bright white). \u201cThis is not de rigueur these days in remote camera work as infra-red or low-light flash is the thing,\u201d Kittle said.\u201cBut we need to identify individuals in order to estimate population densities etc. and only incandescent flash is capable of that for a moving animal.\u201d<\/p>\n

However, the technology still comes with its own share of glitches. \u201cThe camera trap is triggered by data from a highly sensitive Passive Infra-Red motion sensor,\u201d said Watson, adding that deploying this technology in Sri Lankan parks has been a steep learning curve. \u201cIn Wilpattu we found that the sun rays in the morning could interfere with the beam, and we would have 3000 shots of sunlight,\u201d she said.
\n\u201cIn the Horton Plains dew and mist would trigger the trap, in Ritigala ants were building nests inside the lens, and in the Peak Wilderness Sanctuary we have all these pictures of leopards with a spider web across one corner of the image. Thank god, they were still usable.\u201d<\/p>\n

Watson says that there are between 700 and 1000 of this apex predator across the 65,000 sq km island. \u201cThey are a keystone species, in ecological parlance,\u201d Watson told me,\u201cThey are more important to the system than their numbers would suggest.\u201d She explained that leopards are an \u201cumbrella species\u201d \u2013 because they are wide ranging animals, protecting them would mean protecting many others in the same territories.<\/p>\n

The team uses scat\u2014i.e. leopard feces\u2014analysis to understand the leopards\u2019 diet and hunting patterns. \u201cFelids have very short guts and pass out hair, bones, nails, quills etc. undigested,\u201d said Kittle. Efforts are underway to fine tune mathematical equations that can then transform scat analysis output into an estimate of biomass consumed, providing a clearer, more reliable picture of leopards\u2019 dietary choices.<\/p>\n

Kittle and Watson have watched the post-war transition with interest, and have been curious about the conflict\u2019s impact on local wildlife. Watson points out that war can lead to decimation of habitats and rampant poaching, but that in other cases \u201cmines can also keep people out\u201d, somewhat protecting wildlife from human intervention or development.<\/p>\n

Now, as people return to the formerly war torn areas in the north and east, they have begun reclaiming lands or clearing new acres in previously untouched areas like the sprawling forests of the Wanni. They\u2019re building homes and preparing the once wild land for farming. But this trend is not confined to one part of the island, and everywhere protected areas are coming under threat.<\/p>\n

\u201cI think the big concern is the pace of this whole post-war development drive,\u201d warns Watson. \u201cThere is so much we don\u2019t know, so many areas we haven\u2019t explored. We could be losing species we never even knew about.\u201d<\/p>\n

But Kittle said studying the leopard has left him \u201ctentatively optimistic.\u201d<\/p>\n

\u201cFor us, there\u2019s always this thrill, no matter how often you see the animal. You have this respect for its ability to exist in very compromised locations, often alongside people, with minimum conflict. You have to admire that.\u201d<\/p>\n
