A Walk in the Woods

     (in the Nilgiri biosphere reserve)

The Nilgiri biosphere reserve and its constituent parts - source: Wikipedia Commons
Continuing our quest to see more of the tri-state Nilgiri biosphere reserve we bused south from Mysore through the heart of three abutting national parks in three different states - Bandipur National Park in Karnataka, Wayanad Wildlife Sanctuary in Kerala, and Mudumalai National Park in Tamil Nadu. Our timing was a bit unfortunate - it was April, the driest time of the year just before the monsoon starts in late May, and most of the core areas of the parks were closed due to the increased likelihood of a careless cigarette butt thrown out of a window starting a forest fire. But upon arriving at Mudumalai National Park we found that although the core area was closed, it was still possible to see some of the buffer area on jeep tours and guided walks. So after finding a cheap but decent hotel and meeting the resident toad living under one of the beds we went out for an evening jeep safari in the lands buffering the core area of the national park from human encroachment. These areas are used for low impact human activities, such as limited grazing and fodder collection, and serve to protect the core area from such activities. The landscape in this area was very park-like - dense stands of trees interspersed with open grassy areas with closely cropped grass, probably grazed by both wild and domestic animals.

Our jeep safari was a bit of a disappointment - we didn't see much other than chital deer and some hulking vultures squatting in a tree, waiting for a pack of stray dogs to leave the corpse of a calf. Supposedly our tour guide kept getting wind of elephant sightings from other jeep drives, and so we tore back and forth trying to find an elephant for ourselves.  No luck.  We did, however, get to ride on the roof of our jeep!  



Next morning we ventured out on foot with our guide into the buffer area. The stillness of the early morning misty forest was broken by distant music from a village temple. Primary targets for the morning - elephant and tiger. In addition to the English-speaking safari organizer, we also had an inscrutable local village man with us. He wore a dohti and turban and padded through the dewy grass with bare feet. Not once during our three-hour walk did he look at or speak to us tourists. It was his job to 1) find us some wildlife, and 2) make sure we weren't eaten by/stepped on by said wildlife. Going on safari in elephant territory on foot is quite a different experience than in a jeep. As Lonely Planet puts it, hiking safaris sound great until you really consider the phrase "trampled to death".  As we slipped through the morning forest we kept our eyes open for tell-tale signs of the proximity of wildlife. These can include warning calls from other animals, broken branches, and of course, scat.  Our guide was very excited when he found this still-steaming pile of elephant poo. "Very fresh" he said. "Elephant must be close".

Sure enough, just a few minutes later, we saw it, our first wild elephant encountered while on foot.  We kept a very respectful distance from it, and because we were downwind and very quiet, our guide said that it likely didn't know we were there. Elephants have excellent hearing and sense of smell, but poor eyesight. After a few minutes, it faded into the scrub, moving surprisingly gracefully for such a big animal through the dense vegetation. I'm no expert, but this one looked to me like a young-ish female. Any thoughts, all you elephant aficionados out there? No tigers seen on this trip, sadly.  Now that would be an intense on-foot encounter!

Biligiri Rangaswamy Temple Wildlife Sanctuary

The second biosphere reserve on our itinerary was the Nilgiri Biosphere Reserve, a massive 5,500 square km area straddling the borders of Tamil Nadu, Karnataka, and Kerala. Encompassing about eight separate yet contiguous protected areas of various designations, the Nilgiri Biosphere Reserve preserves a variety of grassland and forest types in the hilly landscape of the Western Ghats in southwest India. One unique characteristic of the Nilgiri Biosphere Reserve is the prevalence of indigenous tribes, or adivasi, in and around the forests.                                                                                                  
Our first taste of the Nilgiri was through a wonderful visit to the Biligiri Rangaswamy Temple Wildlife Sanctuary, a protected area in Karnataka several hours from Bangalore. The Bangalore-based NGO and research organization ATREE (the Ashoka Trust for Research in Ecology and Environment) invited us to visit their field research station in the wildlife sanctuary. Never ones to turn down invitations to wild and wonderful places, we hopped on a bus from Bangalore to Mysore and then onward to a series of small villages inside the sanctuary  And a sanctuary it is - we actually saw wild elephants from the public bus on the way to the field station!

The wildlife sanctuary is named for and located around the Biligiri Rangaswamy Temple, a Hindu temple dedicated to the Lord Ranganatha, locally known as Biligiriranga. Sitting perched on top of a hill with a commanding view over the sanctuary's forested hills, the temple supports an abundance of simian entertainment. Walking through the monkey-infested temple grounds at the top of the hill was rather like making your way through a minefield - unpredictable monkeys rushing here, chasing each other and occasionally showing an unseemly interest in bananas I may or may not have had in my backpack.  



While staying at ATREE's field station we took a safari or two into the surrounding jungle. On our first trip we met a rather feisty young male elephant.  Lurking in the trees just off the road, he first watched our jeep for a moment and then lumbered out, head swinging and looking a mite aggressive. Our driver responded promptly, gunning the jeep down the rutted road, not enthusiastic about what an angry 10,000 lb mammal could do to his vehicle (and passengers). Also seen's include the ubiquitous langur and rhesus monkeys, chital deer, and a most impressive animal I've seen nowhere else, the Indian gaur. The gaur is the largest species of wild cattle in the world, bigger than the Cape Buffalo or American Bison. These truly massive animals are very shy, and we caught just a glimpse of two individuals as they faded into the lantana in the dim dawn light.           After the bustle of Bangalore, the BRT was a glorious retreat - the blare of bus horns replaced by bird song, the  smell of half-combusted disel fuel replaced with fresh mountain breezes.




One of ATREE’s partner organizations in the Biligiri Rangaswamy landscape is an NGO called Vivekananda Girijana Kalyana Kendra (VGKK), a social entrepreneurship organization dedicated to the sustainable development of the tribal people living in and around the biosphere reserve. In the BRT the VGKK works mostly with the Soliga, a tribal group who have lived in the forests of the BRT for thousands of years.  Their lives and livelihoods are inexorably linked to the forest in which they hunt, gather wood and forage. This largely sustainable use came under threat in the 1970s from strict wildlife and forest conservation policies instigated by Prime Minister Indira Gandhi. The 1972 Wildlife Conservation Act and the initiation of Project Tiger in 1973 have been responsible for tremendous conservation successes. However the “inviolate area” theory upon which Indian wildlife conservation is based has done enormous damage to tribal groups who suddenly find themselves evicted from land they have lived on for centuries.

Within the BRT Wildlife Sanctuary VGKK has built an “organic village” complex containing a school for Soliga children, a community hospital, and a vocational training center. The Soliga school sounds like a very rigorous institution: the children’s schedule keeps them busy from 5am until 9pm! ATREE and VGKK have also involved the Soliga in a participatory resource monitoring program, building on Soliga traditional knowledge to promote environmental education and ensure the sustainable harvest of forest resources.

The success of this community-based conservation experiment has high stakes – in January 2011 the wildlife sanctuary was designated as a “Tiger Reserve”, a very restrictive conservation category that excludes all human use of the area. This designation requires that all 574.82 sq km of the BRT be free from human habitation. In effect, 1,500 people will be evicted for the benefit of the estimated 35 tigers living in the reserve. Although the evictees will be compensated with money and property outside the reserve, many do not want to leave their ancestral land.  ATREE is helping the Soliga present a case to the Forest Department that their innovative participatory conservation strategies will protect the tigers without requiring mass relocations. The outcome of this legislation is being closely watched by conservationists of every persuasion and could well mark the beginning of a new trend in Indian wildlife conservation policy.

The Sundarbans


The unique ecosystem of the Sundarbans is highly vulnerable to climate change. Sandwiched between the freshwater flow of three major rivers from the north and the ever-shifting sea to the south, the mudflats and islands of the Sundarbans are constantly eroding, accumulating and being reshaped. One potential impact of climate change in the region is increased storm intensity. The good news is that the Sundarban mangrove forests serve as a buffer, mitigating storm surges before they reach inland areas. The bad news is the increased risk from typhoons for the four million people living in here.

The entire Sundarban ecosystem is also extremely low-lying, at or within a few meters of sea level. Current climate change projections estimate that a sea level rise of 28 cm above 2000 levels is likely to occur in the next 50-90 years. This would result in a 96% decline in Sundarban tiger habitat, with similarly dire consequences for the area's human inhabitants.

Accurate maps of the Sundarbans island system are hard to find, partially because the landscape is always shifting and maps are not accurate for very long. Another reason for the lack of detailed maps is the government's thought that good maps facilitate poachers, illegal immigrants from Bangladesh, and black-market cattle smugglers moving cows across the border from Hindu India to Muslim Bangladesh. This coarse map from the Sajnakhali Wildlife Sanctuary museum is one of the best I've seen.

When asked to identify the biggest environmental threat to the Sundarbans, many of the government and NGO officials in Kolkata and Canning with whom I spoke did not mention climate change. Rather, these experts cite human population density and poverty as much more immediate problems. The Sundarbans is one of the most densely populated areas in the world.  Over half of the region's historical mangrove forest has been cut down for firewood and other subsistence needs. The remaining forest, both inside and outside of the national park, is regularly exploited for timber, fuel, pulpwood, thatching materials, honey, bees-wax, fish, crustaceans and mollusks. The West Bengal Forest Department is responsible for the preservation of the protected areas. However even this somewhat entrenched bureaucracy recognizes the impossibility of strictly enforcing all the rules. Sundarban subsistence harvesters are extremely poor and lack alternative means of making a living.  Before the Sundarban ecosystem can in practice enjoy the full protection that it has on paper, the socioeconomic situation for local people must be greatly improved.


The relationship between local people and the Forest Department has gotten much better in recent years. Twenty years ago, villagers regularly killed wildlife that strayed out of the national park and also illegally entered the park to poach tigers and other animals. Nowadays poaching has been much reduced and villagers will turn straying wildlife over to the Forest Department. In exchange, the Forest Department has done an increasingly good job of involving local people in environmental decision-making through joint forestry management (JFM) programs. The Forest Department has also taken steps to improve socioeconomic conditions in the villages and increase resiliency to climate change by digging wells, planting mangroves along the mud embankments separating agricultural fields from the sea, and promoting economic opportunities.


From the Sajnakhali Wildlife Sanctuary we took a day-long boat cruise through the watery roadways of the Sundarbans. The 3-meter rise and fall of the tide was dramatic as the mudflats at the edge of the forest disappeared and then reappeared as the day wore on. We didn't see the famed Sundarban tiger, but encountered birds galore as well as many chital deer, the tiger's main source of food.  Right around camp we ran into the resident mongoose begging for food at the kitchen door, as well as a fat 5-ft water monitor lizard. Small fishing boats plied the water, some sticking to the legal side of the channel and some stealthy drifting through the backwaters, deep into the protected forest. These men risk more than arrest and fines by working in these areas. Sundarban tigers are notoriously predatory towards humans. Small Sundarban fishing boats are typically operated by two people, and stories abound of one man disappearing off the back of the boat with barely a splash, his friend in the prow not noticing his absence until the lull in the conversation becomes awkward.

The Journey South (the Heart of Darkness)


Kolkata is the gateway city to one of the most unique and celebrated ecosystems on the planet - the Sundarbans. The single largest block of tidal mangrove forest in the world, the Sundarbans stretches for 10,000 sq. km along the Indian and Bangladeshi coastline of the Bay of Bengal. Formed by the confluence of the Padma, Brahmaputra and Maghna rivers, this massive delta supports unique flora and fauna as well as providing critical ecosystem services to Bangladesh and the Indian state of West Bengal. 

The Sundarbans, literally translated as "beautiful forest" in Bangla, is a bizarre landscape of flat mangrove-covered islands, rivers and mudflats. Transformed twice daily by the endless rise and fall of the tides, all life here (human, plant, and animal) is adapted to the ever-present saltwater and impermanence of the land.  Due to the extreme salinity gradient between the ocean and landward sides of the delta, the Sundarbans is highly biodiverse. Additionally, the complex underwater topography created by mangrove roots provides an important nursery to young fish and crustaceans. According to the 2011 nationwide census the Indian side of the Sundarbans supports the nation's single largest population of endangered Bengal tigers.  These roughly 270 animals are uniquely adapted to their watery environment and capable of swimming long distances from island to island. 

The Indian Sundarbans are protected by multiple layers of legal designations, including tiger reserve, national park, and wildlife sanctuary. But well before these exclusionary conservation policies came into effect, the Sundarbans were home to millions of people. The area's human population now stands at over four million, mostly landless agricultural workers who depend heavily on fishing, shrimp aquaculture, and the collection of forest products like wood and honey. Harvesting wood and honey, as well as netting the shoreline for baby shrimp, often require people to illegally enter areas of protected forest. Once in the forest, in addition to damaging the integrity of the national park, these people are vulnerable to tiger attack. Sundarban tigers kill between 100-250 people every year, far and away more than in any other area in India. 

What brought me to this tiger-infested mangrove swamp, you may ask?  As part of my investigation into ecosystem-based adaptation in India, I was interested in looking into adaptation activities and actors in a variety of different landscapes.  For my study sites I chose the Indian UNESCO biosphere reserves - areas designated as having special biological and cultural diversity which seek to reconcile conservation with economic and social development. Biosphere reserves are supposed to be model landscapes in which to test and demonstrate innovative approaches to sustainable development. I was visiting the Sundarbans, the first of my Biosphere Reserve visits, to see if this was actually the case. 

But before my investigation could begin, I had to get there.  Easier said than done.  From Kolkata we caught a local train, which involved a mad, no-holds-barred scramble with the fifty other people trying to enter the carriage for a few square inches of bench space on which to park my bum.  Having secured a spot, I uncomfortably occupied it for the next three hours until our arrival in Canning, the largest town in the Sundarbans region (named after Lord Canning, Governor General of India from 1856 to 1858). From Canning we rode on the roof of an extremely overcrowded shared van for an hour to reach the end of contiguous land in the village of Sajnekhali. Piling onto a local ferry we motored across a river channel to Gosaba. A bicycle rickshaw and one more ferry later, we finally arrived on Sajnekhali island, within the wildlife sanctuary. Next post: the Sundarbans!

In Search of the Snow Leopard

Mission 2:  See a Snow Leopard

The Prelude

One fine autumn evening last year while sitting at an outdoor table at the Tip Top Teashop in Mussourie, three Hindi students began to discuss how awesome it would be to see a snow leopard in the wild.   For me, the conversation was entirely theoretical at first.  I mean, come on, how many of those things are there left in the world anyway, like six?  Such an expedition would involve expensive things like guides and good outdoor gear.  And not least of all, it’s flippin’ cold in Ladakh in February. But as we continued to discuss and research, the idea began to seem more feasible. 

The Background

Snow leopards are found in the high reaches of the Himalayan mountains and on the Tibetan plateau.  Their range stretches from eastern Afghanistan in the west, through Pakistan, Tajikistan, Uzbekistan, Kazakhstan and Kyrgystan to Mongolia and Siberia in the east, and from China in the north down through the Himalayan mountains to Nepal and India in the south.  The best place to see snow leopards in India is in the state of Jammu and Kashmir in the district of Ladakh, a land north of the main Himalayan range. The landscape here is extreme - cold, precipitous, and high, as can be seen in this photo taken from the airplane. Looking for a snow leopard here is like looking for a flea in a farmyard.

The snow leopard (Panthera uncia) is a big cat weighing  between 27 to 55 kg  Usually a solitary beast, snow leopards only travel in pairs during the late winter mating season.  Their main prey in their Indian range is the bharal (Himalayan blue sheep) that also frequent the high mountain passes of Ladakh.  Various estimates put the world-wide snow leopard population in the wild between 4,000 and 7,000, while the Indian population of snow leopards is estimated to be between 100-200 animals. (In contrast, according to the results of the 2010 tiger census, India has an estimated 1,706 tigers.) Snow leopards are notoriously difficult to study.  Their mountainous habitat, secretive nature, and perfect camouflage make sightings rare. Considered the holy grail for wildlife spotters, only around 1,000 foreigners have ever had the privilege of seeing a snow leopard in the wild.  We would be exceedingly lucky if we were to see one.

Most people who get a bee in their bonnet about snow leopards sign up for expensive guided expeditions run by a handful of eco-tourism companies.  These 10-12 day trips can set you back around $4,000, not including international airfare from your home country.  We, being cheap, decided to free-style it.  We found several sample snow leopard trip itineraries online, and from these determined that our best bet was to plan an expedition to the Rumbak valley within Hemis National Park, south of Leh.  Hemis National Park is a massive mountainous landscape, understandably one of the least visited national parks in the country.  It provides critical territory to IUCN red listed endangered animals, including the Tibetan wild ass, the black-necked crane, and wolves.  In the summer snow leopards live above the tree line between 3,000 and 6,000 meters, but in the winter, follow prey to lower altitudes.  So although it’s a bit counter-intuitive that mid-winter is the best time for snow-leopard spotting, this is when the animals are most accessible. 

The Plan

We returned to Leh after our aborted Chadar River trek and immediately began to gear up again for our second expedition.  This time we would be less mobile – one fixed camp would be set up in the Rumbak valley, midway between two side valleys called the Tarbung and Husing valleys.  These two valleys and the Rumbak valley between them is the closest thing around to a snow leopard super-highway.  Which is to say, maybe 5-7 snow leopards are sighted there a year - after thousands of man-hours of searching. Not such great odds. Like many big cats, snow leopards are most active in the morning and evening.  Every day we would rise early and be scanning the slopes in one of the two valleys by 6am.  We would return to camp for breakfast around 9:30am, and then spend the late morning and afternoon roaming the valley floors for fresh tracks and other signs.  Around 4pm we would again take up our station on a hillside, watching the boulders and snow slopes for movement or a rock at appeared to have ears.

After hiring two experienced guides and a cook, we repacked our bags and set off from Leh to Hemis National Park.  We had rented a larger kitchen tent in anticipation of needing a space to stay warm in the evenings.  It was such a bulky thing that we had to hire three tiny donkeys at the base of the valley where the road ended to carry our gear up to the camping spot.  Our first morning was spent setting up camp on one of the few flat spots in the narrow valley.  We found another group already there – a well-equiped expedition of seven clients, three guides and a number of porters organized through Zegrahm Expeditions

Our campsite in the Rumbak valley
The Chase

On our first morning we rose early and by 6:30am were scanning the slopes from a high vantage point up the Husing valley.  The grey, cold morning was utterly quite, the silence broken only by the occasional call of a bird.  We divided the hillsides around us into sections and each took responsibility for searching one area.  Around 7:30 one of the guides saw something; what he originally took to be a blue sheep was suddenly revealed to have a long furry tail. The animal disappeared behind a rock before anyone else got a look. Suddenly excited, we bounded further up the hill to try to get a look. Several minutes later, R. found tracks in the snow from two leopards travelling together – likely a mating pair. One set of tracks had a reoccurring spot of blood in one of the prints, an injury sustained from the sharp rock scree covering the slopes at that altitude.  We followed the tracks over the mountainside and the chase was on!

Knowing the snow leopards were travelling much faster than we were over the steep and rocky terrain, we still felt compelled to follow them in the hopes of catching a glimpse of them in the distance.  We trailed them for 3 hours, gaining and losing hundreds of meters in elevation as we picked our way over the shoulders of the mountains.  R., with the fortitude and sure-footedness of a young goat, bounded ahead with the guides, following the tracks as they passed over snow, scree and boulders.  I lagged behind, lacking the energy for this type of extreme trekking before breakfast.   Finally around mid-day, high on the mountainside, it became evident that we could follow no further.  The tracks disappeared down a slope too steep to follow.  Regretfully we turned back, picking our way hundreds of meters back down the mountain to camp.

The Sighting

Upon reaching camp close to 2pm, we fell upon our neglected breakfast like a pack of ravenous wolves.  My shoes were wet and my clothes were all torn up from our morning’s adventures, so after getting a little food in my belly I pulled the insoles out of my boots to dry and removed my shredded wind pants, settling down to eat in my long underwear.  Suddenly there was a commotion outside of the tent – shouts echoed up and down the valley, and suddenly people seemed to be moving, running.  I tossed aside my plate, and shoving my feet into my sole-less boots, took off down the valley with my shoe laces flapping, wearing only my long underwear and a thin sweater.  I wasn’t exactly sure what had caused the sudden urgency, but members of the other expedition were headed down towards the Husing valley, and the only thing I could think was “SNOW LEOPARD!”.

Finally reaching the opening to the valley, I could see the guides and the faster members of the two groups already sitting 50 meters up the scree slope with binoculars and spotting scopes trained high up the hillside.  They obviously had something in view, and so, pausing ever-so-briefly to tie my boots, I flung myself up the slope, terrified that whatever they were looking at would disappear before I could get a look.  I reached the group dirty, cold and half-dressed, and peering through a spotting scope at the opposite side of the valley, I saw it.  The snow leopard. 
Snow leopard spotting
The handsome beast was almost a kilometer away, stalking right along the top of the ridge line on the opposite side of the valley.  Silhouetted against the sky as it was, I could even see puffs of its hot breath condensing in the cold afternoon air.  The leopard’s enormously long and thick tail curved up elegantly behind it.  After a moment it sat down just behind the ridge line, leaving only its head visible.  I attempted to take some pictures through the spotting scope, with the following result.


You can tell that's a snow leopard, right?  Fortunately, we don't have to rely entirely on my inadequate camera technology. Our friends in the other expedition had far better equipment and were generous enough to share some of their images.  Here they are, folks.  Our view of the snow leopard, one of the rarest wildlife sightings in the world.

After resting on top of the ridge for a few minutes, the snow leopard came back towards us, descending just a little down into our valley. At one point it stopped to spray urine on a rock in a territorial scent-marking behavior.  We continued to watch, sharing the few spotting scopes between us.  Finally, after almost an hour, as dusk began to fall, the leopard disappeared into the gloom between two boulders, and we did not see it again.  Happily, we shuffled off to our camps, ecstatic to have been so lucky.

Snow leopard tracks
Shockingly, our sighting occurred on the first full day of the trip. We still had 4 days in the valley to try to replicate the experience.  Every morning and evening we braved the sub-freezing temperatures to sit on hillsides, scanning the slopes for movement.  Signs were everywhere. Most mornings we would find fresh tracks in the snow on the valley floor, sometimes passing within a hundred meters of the tents. One evening we were up on the hillside in the gathering dusk, preparing to return to camp, when we heard a low moaning cry echoing through the valley. Our guides, Jingmet and Panchok, recognized the noise as the call of a male leopard searching for a female.  We ran up the hill to a viewpoint and spent the last half hour of light scanning the valley below.  Although we heard the call several more times, landscape was completely still. The same call, kind of a choking moan, was heard during the night on several more evenings.  But we never saw one again.  After our early success this was disappointing, but we were very cognizant of our extreme luck in seeing one so early on.  It was very exciting to see the tracks and hear the calls, daily evidence that the cats were still there, slipping like ghosts through the scree and boulder fields.

And that, friends, is how we were able to join the small group of westerners who have seen a snow leopard in the wild.  Pretty awesome.
