‘A Needle in a Haystack’: A Sony S600 catches a leopard eating prey
Sometimes, things happen that are unexplainable and spooky. That goes for the following story. I have just returned from Africa and while on safari, was able to slip two camera traps in the bush (a Sony S600 and W7) at several locations. But the weirdest setup was in Tsavo East National Park in Southern Kenya not far from the infamous ‘Man-eaters of Tsavo’ site.
To get a perspective of how huge this place really is (Tsavo – East and West) is the largest national park in the world at more than 43,000 square kilometers (the size of Wales, Israel and New Jersey). Finding a leopard is like finding the proverbial ‘needle in a haystack’.
Leopard’s prey: A wild cat and a black-backed jackal
One morning as my companion, driver and guide Patrick Mjoroge and I were out on a game drive (as they are known), he spotted two leopard kills hanging in a tree by the side of the road. We stopped and saw a wild cat wedged on top of a jackal in the branches, and both ‘dead as door nails’.

The big cat for a later meal stashed these two small predators and so we waited for a while but in vain. Then it dawned on me: why not just throw my S600/SSII/1010 on the ground in a hollow piece of dead wood pointed up at the big tree. It was worth a shot! Later that day, we drove by several times but the leopard was no-where to be seen.

The carrion was still there so I decided to let it soak overnight until the next morning thinking the carnivore might come at night to eat its prize. I took a few shots of the hanging dead and the set-up, and we departed quickly not wanting to hang around obviously. The leopard on the ground is extremely fast and I was not sure how close it might be waiting, and we might just turn into dinner.
Bright and early the next morning, we drove directly to the tree and found the two kills gone. A small tree branch had fallen right in front of the cam and I thought I had missed the cat for sure. As I scanned through the images, I could see nothing but a large leg in several frames. A giraffe had almost stepped on the cam before we arrived and I could see its head up close to where the kills had been. I was a bit disappointed.

Then, I decided to scroll through again and noticed one frame was darker just before the giraffe shots. I zoomed in and almost jumped out of the truck. Low and behold, I saw spots in the crotch of the tree and then saw the leopard’s head looking down towards the cam with the jackal in its mouth. The big cat had visited late in the afternoon and the background sky was nice and blue. I was speechless for a few moments until I could talk again.

I began jumping up and down in the back until Patrick told me to calm down. I showed him the shot and we both began celebrating this remarkable camera trap event. It definitely was worth several rounds of drinks or ‘sundowners’ as they are known in Africa later at the bar in the tented-camp.

Weird is an under-statement and the ‘spirits of the wild’ had answered my wishes. I have cropped and enhanced the leopard shot so it can be seen quite clearly. Remarkable is all I can say and the little S600 did a herculean job of catching a ghost!
More set-ups to follow: The S600 also traps hyena, baboon, impala, waterbuck, and the W7 catches elephant plus a bushbaby in a hotel bar getting the largest and one of the smallest mammals found in Africa. It was an amazing trip to the ‘Dark Continent’ as it was known in the old days, and hope everyone enjoys these camera trap photographs.

The Asian Leopard: Thailand’s second largest cat
Friday, July 23, 2010 posted by Bruce 8:57 AM
WILD SPECIES REPORT
An ambush predator – solitary, stealthy and naturally camouflaged
The late French poet Robert Desnos (1900-1945) wrote a short poem entitled “The Leopard”
“If you go into the woods, beware of the leopard.
He meows in subdued voice and arrives from nowhere”
Black leopard in the late afternoon sun
The leopard Panthera pardus described by Linnaeus in 1758 is the second largest cat in Thailand. Once upon a time, leopards could be found in all the forests of the Kingdom. These felines are still surviving quite well in protected areas in the West, and some in the South. The central, eastern and northeastern regions have no reports of leopard for some time now.
A few have been reported in Phu Khieo Wildlife Sanctuary in Chaiyaphum province, but for some reason they have disappeared from most remaining forests. The reason these areas have no leopards are quite simple; prey species has been hunted out including the leopard itself for its pelt and bones, and encroachment has destroyed much of its habitat.
Sighting a leopard in Asia is extremely difficult, and even catching a rare glimpse of this very essential top predator is tough due to its solitary and stealthy behavior. However, luck can sometimes play an important part in viewing the leopard and I feel lucky to have seen and photographed them on quite a few occasions.
Leopard camera trapped in Kaeng Krachan National Park
The most thrilling or heart stopping adventure with a black leopard happened in Huai Kha Khaeng about five years ago while I was sitting up on a bluff overlooking the river. A photographic blind was erected on the rock-face about 20 meters up with a small trail that enabled me to get into the hide. It was a neat location that I had dreamed of sitting here for many years prior. The sun was bright and the weather was warm during the dry season.
About 9am, several monks down by the river passed on but did not see the camouflaged structure as they went their way. After that, I came down for lunch and set some camera traps at a mineral deposit nearby. At 2pm, I settled back in the blind and began a vigil of the river. I started to feel a bit groggy as the sun was beating down on my position. I moved my camera in to save it from the direct sunlight.
All of a sudden, I was startled by a guttural growl outside the enclosure. I stood up slightly and peering out the window came face to face with a huge round black head and yellow eyes about two meters away that penetrated my soul. My first instinct reaction; it was a big black dog. But that quickly changed as the creature stared intently at me before bounding down the trail it had come up. The big cat was gone in a split second. Of course there was not enough time to get any photographs. The incident surely is etched in my memory.

Why had the leopard come so close without smelling me? On that particular day, I was using an old hunters technique by collecting fresh wild water buffalo droppings and putting them in front of the blind, and that probably covered my scent. Maybe the leopard thought there was a newborn calf, or an old weaken animal. Or maybe it used this natural place overlooking the river to spot prey like sambar, barking deer or wild pigs that are abundant here and came up to investigate. The vantage point is on a bend in the river and one can see for quite a distance both ways.
I will never know how close I came to being attacked by a leopard but it was a heart stopper for sure. I sat motionless for quite sometime. Only a few sticks and camouflaged material separated me from a wild creature armed with fangs and claws. On that day, the spirits of the forest looked after me, or was it the ‘Spirit of the Forest’. I like to believe that was the case. I hope one day to go back and stake out this bluff, and believe this leopard is probably a resident around here. Previously, I camera trapped tiger and a yellow phase leopard not far from here.
A leopard resting on a wildlife trail
Speaking of leopard attacks, my close friend and associate Dr Lon Grassman was once seriously injured in Kaeng Krachan National Park, Phetchaburi province by a leopard while working there on a survey to camera trap and collar the big cat. When Lon released one, it looked up and turned on him in a split second mauling his legs and arms. It was a close call but he survived to carry on his work researching wild carnivores. Lon established the home range and other behavior patterns of leopards in the park.
He then moved to Phu Khieo Wildlife Sanctuary, Chaiyaphum province in the Northeast and continued this work catching and releasing quite a few golden cats, clouded leopards and a marbled cat. He eventually received his doctorate for his excellent work.
In the beginning of my profession as a wildlife photographer, I was very fortunate. The Director of the Wildlife Conservation Division of the National Parks Department (DNP) at the time, my dear friend Dr Viroj Pimmanrojnagool (now retired), had confidence in me and gave permission to enter the realm of the leopard and the tiger, something not easily acquired. Entry into wildlife sanctuaries has always been very restricted but is possible with the right qualifications. Viroj and I are still very close and I visit him from time to time at his durian farm in Surat Thani down south where he is happily enjoying retirement.
Leopard in the bamboo – my very first photo of the big cat
My first encounter with the sleek cat goes back to the beginning of my career more than a decade ago. Driving into the forest late one afternoon in Huai Kha Khaeng Wildlife Sanctuary, a World Heritage Site, the sun was low but the light still quite good for photography. The protected area is situated in Uthai Thani province and is part of the Western Forest Complex.
I was about to capture my very first Asian leopard on film. This was in my early days as a wildlife photographer with a newly acquired Nikon N90s camera and 300mm lens. I was on a learning curve that would take me into some unique natural habitats and bump into some very unusual animals around Thailand.
Leopard posing in Kaeng Krachan
About 4pm some 10 kilometers from the headquarters as I was driving in, a leopard jumped in front of my truck and bounded up the steep embankment on my right. I gently came to a halt and there looking down at me was these two big yellow eyes that brought my attention to 100 percent. In the meantime, I had already grabbed my camera and started snapping through the window as fast as possible but quickly slowed the pace concentrating on focus. After a few more shots, the spotted cat melted into a bamboo thicket and was gone. The encounter was measured in mere seconds.
I sat in the vehicle for a few minutes to catch my breath as my heart was thumping. A close encounter with a carnivore capable of tearing us apart is something that can get the blood flowing. I finally got going again as my destination was still a couple of hours away deep in the forest.
Leopard on a sambar kill – my first camera-trap photo of the feline
Arriving at the Kabook Kabieng ranger station just at dusk, the head of the station Loong Waitanyakarn, another good friend, came immediately to the truck and said, “ a sambar mother and fawn have been killed by a leopard or wild dogs not far from the station and let’s go look”.
It didn’t take me long to ponder that an opportunity had presented itself. I had a new infrared sensor for my Nikon camera and decided to set-up the unit next to the dead sambar. A new role of film was loaded and the lens focused on the mother deer. The sensor was active infrared that uses a transmitter and receiver hooked to the camera. When an animal trips the beam, the shutter is activated taking a self-portrait. At the time, this technology was rather new but I needed it to supplement my regular photography.
Black leopard posing for me at a hot spring
The next day at noon some 10 kilometers away, Loong took me to a tree stand over-looking a hot spring. The box-like structure was quite high up and it was a bit scary getting situated in the blind but finally, I settled down with my Nikon 500mm lens and camera scheduled for a three-day stint. The mineral deposit and hot springs attracts many large mammals including elephant, gaur, banteng, tiger, leopard, wild dogs, tapir and many other animals that come for the life-giving minerals, or for prey.
Black leopard at the hotspring
About 3pm, a troop of leaf-monkeys visited the hot springs for a quick drink but did not stay long. They had been spooked by something as they all panicked and gave flight in the trees up the hill. A short time later, a black leopard appeared from the top end and walked over to where the monkeys had just been. The sun was low in the sky and I could see the leopard’s pattern of rosettes through the lens that jumped out at me.
My heart began racing as the stealthy cat stopped at the top to take a drink. It stayed for about an hour. I calmed down but continued shooting changing several rolls of film and watching this magnificent creature. Just before the sun was gone, it moved closer to the tree I was in and then walked across the stream. The cat plopped down on a log and stretched out posing for me, all the while looking up at my position. I kept shooting and then it came even closer before veering off probably spooked by my scent. As the leopard moved through the forest, monkeys, barking deer and sambar barked at the predator.

I will never forget these encounters. Three leopards in two days are pretty good going for a new wildlife photographer and it was truly the beginning of many sightings and photographs of this amazing carnivore. I have seen loads of them on film while working in Kaeng Krachan. Both black and yellow phase were camera trapped in three separate locations in the interior at almost every location.
The Tenassarim Range in southwest Thailand is an absolute haven for the leopard due to a very good prey base here. Tigers also survive and have overlapping territories with the spotted cat. Both species hunt during the day and night. My old friend Suthad Sapphu, a forest ranger in Kaeng Krachan, was extremely helpful while we were camera trapping the big cats.

Without doubt, the future of the leopard depends on one thing only – the complete protection of the remaining forests where they live. If the national parks and wildlife sanctuaries remain intact with a high number of prey species, the big cats will survive. But if over-development, poaching and encroachment are allowed to continue, the large cats will eventually disappear.
Unfortunately, too much time and money is wasted by too many organizations talking about saving wildlife and their habitats, with very little actually being done. Human population growth will eventually destroy most wild places. Only true protection by some dedicated people will slow the destruction of nature’s precious wildlife and wilderness areas. It is hoped the leopard, and the tiger, will continue to survive as they have for millions of years.
Leopard Ecology:
Pound for pound, the leopard can take on some seriously large animals several times its size. The leopard is closely related to the jaguar of South America. Both have a spotted coat pattern, incidence of ‘melanism’ or black phase, and relatively short legs.
The present distribution of the leopard is restricted to Asia Minor, India, Southeast Asia, the Himalayas, Tibet, China, Siberia, and Africa. Fossils of leopards were found in Pleistocene deposits throughout Europe, the Middle East, Java, and Africa, some 1.5 million years old, indicating the leopard arrived after the tiger. These secretive cats are mainly nocturnal but in some localities, they are active in the day too. Their populations and ranges are difficult to determine but radio tracking of collared animals has shed new light on their movements and areas they live in.

The leopard is a member of the Felidae family and is the smallest of the four “big cats” in the genus Panthera, or roaring cats. The other three are the tiger, lion and jaguar. The leopard’s range of distribution has decreased radically because of hunting and loss of habitat. It is now chiefly found in sub-Saharan Africa; there are also fragmented populations in Pakistan, India, Sri Lanka, Indochina, Malaysia, and China. Because of its declining range and population, it is listed as a “Near Threatened” species by the IUCN (International Union for Conservation of Nature).
The species’ success in the wild is in part due to its opportunistic hunting behavior, its adaptability to habitats, human settlements and activity, its ability to run at speeds approaching 58 kilometers per hour (36 mph), its unequaled ability to climb trees even when carrying a heavy carcass, and its notorious ability for stealth. The leopard consumes virtually any animal it can hunt down and catch. Its habitat ranges from rainforest to desert terrains.

Big Cats in Kaeng Krachan: The tiger and leopard
Saturday, October 3, 2009 posted by admin 7:42 AM
A look at tiger and leopard evolution in Asia
At the beginning of the dry season in January, the jungle canopy is still mostly green but falling leaves begin to carpet the forest floor as the first cold snap arrives. Some species of trees start their transformation, producing a mosaic of yellows, oranges, reds, browns and greens. For the first few hours each morning, heavy fog blocks out the sun as moisture dissipates from the forest. The Phetchaburi River is crystal clear as it flows through this magnificent forest.

A large predator walks the trails seeking its next meal. Sensing danger, a muntjac barks a warning. The whole community of wild animals is on alert as macaques and langurs cry out from the trees above. A striped carnivore stalks a herd of wild pigs. The nervous omnivores squeal and panic, running through the underbrush to escape. But the big cat is lightning quick – it catches a young pig with sharp claws. The struggle is over in seconds as fangs penetrate to the spine.

The tiger has just made a kill. It lifts the lifeless prey into deep cover and devours the carcass. After feeding, the big cat seeks water for a thirst quenching drink. It will then lie down and rest until the desire to eat or drink begins again. Tigers will sometimes move great distances in search of food. But where there is an abundance of prey species, these magnificent cats continue to live in balance with nature. The average kill ratio for a tiger is about twenty unsuccessful attempts for one actual kill. At a certain time of year, the male tiger will seek out a female to carry on his legacy.

Kaeng Krachan National Park is a great wilderness that sits in the Tenassarim Range in southwest Thailand. It is one of the most beautiful protected areas left in the country. Elephants, gaur, tiger, leopard, tapir, gibbons, hornbills and literally thousands of other plants and animals still survive in a rich ecosystem that is world class.

To understand how the tiger and leopard evolved, we must go back to the beginning of these wild creatures. After the carnivorous dinosaurs died out about 65 million years ago, mammals with sharp teeth, strong jaws and claws replaced them as the top land predators. The first successful mammalian carnivores were the Creodonts that evolved during the Eocene epoch 57-35 million years ago. Creodonts ranged in size from smaller than a weasel to as big as a bear. A bear-dog also evolved during this period. These carnivores all had voracious appetites that were satisfied by large concentrations of prey species, mainly the odd-toed and even-toed ungulates that browsed and grazed the lush forests and plains of the time. The early Creodonts evolved into the modern carnivores that we know today: the bears, cats, dogs and other predators.

The order Carnivora is separated into three superfamilies: The Arctoidea includes marten, weasel, badger, otter, bear and the panda; the Cynoidea are made up of the dog, fox and the wolf; and the Herpestoidea includes the mongoose, civet, hyena and the cat. Most carnivores are dedicated meat-eaters, but some groups such as civet, panda and bear are omnivorous, eating meat and plants.

Nimravidae were the first cats to evolve in the Early Oligocene epoch, about 35 million years ago. They lasted till the Late Miocene, some eight million years ago, when huge grasslands had developed around the world. The large saber-toothed cats were the first of the family Felidae. These long-fanged felines evolved alongside huge herds of grazing mammals like antelope and cattle. There were several different species of saber-tooth, but they all became extinct about two to three million years ago.

Modern cats belong to the family Felidae and include: tiger, lion, leopard, jaguar, cougar and cheetah, and all the smaller cats such as lynx, bobcat, jungle cat, fishing cat to name just a few plus domestic cats. Wild carnivores feed almost exclusively on vertebrate prey and sit at the top of the food chain. Tiger and lion have few predators apart from man but a pack of wild dogs however are a constant threat to the large cats and their offspring. The tiger and leopard belong to the genus Panthera, or roaring cats, that include the lion and the jaguar.

Thousands of years ago when primitive humans lived off the land as hunters and gatherers, they survived by pure instinct. They killed animals for meat and skins, and also gathered many different tools and plants from the forests. As humans became more sophisticated, they used weapons to take down larger animals. Clubs, spears, knives, bow and arrows were all that separated them from almost certain death at the claws and jaws of a predator many times their size.

The possibility of being eaten by a carnivore like a tiger or leopard must have been on everyone’s mind that lived in or near the wilderness. Entering the forest where every step could be the last was like walking a tightrope. Attack normally lasted only seconds as a huge predator pounced from behind, biting the neck and causing almost instant death. Very few people survive such an incident. It must have been a scary environment to live in.
The will to survive, however, was strong and men eventually conquered his fear of the wild cats with more modern weaponry. The tables had finally turned and the predators became the hunted. As human populations and settlements grew, the forests were quickly transformed into agricultural land.

After firearms were invented, European royalty, native kings, landlords, planters, foresters, government officials and many adventurers journeyed to the forests of Asia in search of the tiger. Mostly, they came to prove their dominance over the big cat. A trophy of tiger on the wall or floor at home proved beyond doubt that the owner was the supreme species. One could boast of their prowess as a hunter.
But the fact is most hunters shot tigers and leopards from the safety of a tree-blind, vehicle or elephant back. The cats would be attracted to within gun range by cattle, buffalo or a goat used as bait. For special hunts, hundreds of local villagers were recruited as beaters, trackers and mahouts. To join a shikar (Indian word for the hunt) was the ultimate experience for the adventurous.
The same tiger as above a few moments later
More tigers have been killed for sport in India then anywhere else in the world. In the days of the Raj, it was common to see five, ten or twenty cats lying dead on the ground in front of a hunting party. The Maharajah of Surguja killed some 1,157 tigers during his reign. Some Englishmen claimed to have shot more than 100 tigers. Fortunately in 1972, the Indian government finally banned hunting because the tiger and many other species were threatened with extinction.
The most famous hunter ever to overcome his fear of the big Asian cats was Jim Corbett of India. From 1907 to 1939, he single-handedly dispatched scores of man-eating tigers and leopards. His book ‘Man-eaters of Kumaon’ is a classic. Some cats mentioned in the book had killed hundreds of people. Corbett National Park was established in his honor, and the Indo-Chinese subspecies of tiger Panthera tigris corbetti is named after him.
In Thailand, the tiger and the leopard were also hunted for sport but on a much smaller scale than in India. In the past, rural Thai people living near wilderness areas built houses high off the ground that protected them during the night. But daytime was another thing. If they worked in fields bordering thick jungle or they went into the forest, they risked their lives.
At the turn of the 20th Century as modern firearms, agriculture and transportation took hold in the Kingdom, the forests and wildlife began to disappear. Man-eaters also declined. However, during World War II along the death railway in the Sai Yok district of Kanchanaburi province there were still accounts of man-eating cats. In recent times, there has been no such record. From time to time, domestic cattle are still killed by a tiger or leopard but this is now very rare. Low wildlife densities in the forest and easy prey are the main reason for this occurrence.
Thailand is fortunate in that tiger and leopard plus another seven species of cat still survive in some of the larger national parks and wildlife sanctuaries. Kaeng Krachan National Park is one of those protected areas that still harbor the big cats. Tigers can and do kill the leopard. Although their paths do cross, normally the spotted cat will avoid the striped predator. Documentary accounts and photographs do exist of tigers eating leopards.
In 2002-2003 while carrying out camera trap work in Kaeng Krachan in cooperation with the National Parks, Wildlife and Plant Conservation Department, I was surprised and elated to see both species tripping the same cameras in several areas only days apart. In one month, four different leopards, one of them black, were caught on film. In the following month, a leopard was caught during the day, and a huge male tiger stopped and posed for the camera. Both species were using the same trail for their hunting forays. A few other protected areas like Huai Kha Khaeng and Thung Yai Naresuan wildlife sanctuaries have records of overlapping.
In Kaeng Krachan, an important discovery is that tiger and leopard hunt at all times during the day. It is usually thought they are only active in the late afternoon and throughout the night preferring to rest during the day. More research is required if we are to determine the pattern of daytime hunting by the big cats here. It is probably due to the pristine state of this forest and the lack of human activity.
Without doubt, the future of the big cats depends on one thing only – the complete protection of the remaining forests where they live. If the national parks and wildlife sanctuaries remain intact with a high number of prey species, the big cats will survive. But if overdevelopment and encroachment is allowed to continue, these magnificent animals will eventually disappear.
Unfortunately, too much time and money is wasted by too many organizations talking about saving the tiger and other wildlife, with very little actually being done. Human population growth will eventually destroy most wild places. Only true protection by a few dedicated people will slow the destruction of nature’s precious wildlife and wilderness areas. It is only hoped that the tiger and leopard will continue to survive as they have for millions of years.
Leopard – Panthera pardus
The leopard is closely related to the jaguar of South America. Both have a spotted coat pattern, incidence of melanism (black phase), and relatively short legs. The present distribution of the leopard is restricted to Asia Minor, India, Southeast Asia, the Himalayas, Tibet, China, Siberia, and Africa. Fossils of leopards were found in Pleistocene deposits throughout Europe, the Middle East, Java, and Africa, some 1.5 million years old. These secretive cats are mainly nocturnal. Their populations and ranges are difficult to determine but radio tracking of collared animals has shed new light on their movements and area they live in. ‘Spots’ is more tolerable to humans and their settlements.
Tiger – Panthera tigris
According to fossil evidence Panthera cats branched from the other Felidae about five million years ago in Asia. The first tigers originated in eastern China. Fossils of the earliest tigers date back to the Pleistocene epoch, about 1.6 to two million years ago, have been found in Henan, southeast China, and on the island of Java in Indonesia. The historic range of the tiger covered much of Asia and some of its islands.
However, humans have had an enormous impact on the geographic range of the species. The big cat only survives in 13 countries: Russia, China, India, Nepal, Bhutan, Bangladesh, Burma, Laos, Cambodia, Vietnam, Indonesia, Malaysia and Thailand. The present range is less than five percent of the tiger’s former range. There are less than 5,000 tigers left in the wild.

Heavy storms and floods have closed the visitors’ road, and wildlife has thrived because rangers kept it closed
Saturday, September 26, 2009 posted by admin 6:44 PM
First published in October 2003
Just a three-hour drive southwest of Bangkok, along Phetchaburi province’s border with Burma, lies Kaeng Krachan – Thailand’s largest national park, encompassing 2,915 square kilometers of mostly tropical broad-leafed evergreen and mixed deciduous forests. In the interior live tigers, leopards, elephants, gaur, tapir and many other amazing species. Even the rare Siamese crocodile still lurks in one of the park’s watercourses. Kaeng Krachan is one of the country’s least touched forests.
Black Leopard phase
Prior to the government ban in 1989, logging was carried out in the lowland areas of Kaeng Krachan. Timber cutters cut an 18km road into the interior from Sam Yot Mountain to transport logs from the concession areas. When logging ceased, the Royal Forest Department extended the road another 18km to Phanern Thung Mountain to facilitate visitors to Thor Thip Waterfall.
Kaeng Krachan became a popular destination, with thousands of visitors each year. But too many visitors ruined some areas in the park. Wild creatures, especially mammals, faded into the more inaccessible areas and were not often seen along the road.
In October of 2002, two back-to-back violent tropical rainstorms hit Kaeng Krachan, overflowing the park’s streams and rivers, and inundating much of Phetchaburi province. Five local villagers, along with homes, vehicles, and livestock, were swept away in the worst flooding in more than 40 years. Blame for the flash floods was placed on excessive logging of the past.
Road washed out
There was extensive devastation inside the park as well. Floods washed away many sections of the main road, and more than 50 landslides uprooted trees and blocked access by tourists. The National Parks, Wildlife and Plant Conservation Department (DNP) has to wait for funds to repair the road, and this takes time. That ended the flow of people in their noisy vehicles, and the wild creatures began to use the road in their search for food and water.
Yellow phase leopard in the interior
For the last few years I have worked with the RFD and later the DNP, to carry out infrared camera-trap surveys in Kaeng Krachan to monitor large and small mammals. Some exciting photographs have resulted. Tigers and leopards, both in black and yellow phases, have come into almost every camera trap. The big cats are also surviving in overlapping territories in quite a few areas, especially along the Phetchaburi River, and along the road close to the ranger station on Phanern Thung Mountain.
Indochinese Tiger camera-trapped
Last January, more than three months after the storms closed the road, was a great opportunity to camera-trap. Four camera-trap units were placed at Kilometres 31, 32, 33 and 35, and the units started photographing almost immediately.
Tigers and leopards were now using the road to hunt day and night, and creatures like the very rare Fea’s muntjac were also caught on film. Other animals such as Asian wild dogs, black bears, large Indian civets, leopard cats, common muntjac and porcupines were also camera-trapped.
Fea's muntjac camera-trapped
One of Kaeng Krachan’s biggest advantages (from the animals’ viewpoint) is that the rainy season makes its interior inaccessible. It is almost impossible to move in and out of the main Phetchaburi watershed area when the river is swollen by heavy rains, meaning from June to October. At present, the river is a raging torrent and only professional rope handlers could possibly hope to cross. And this doesn’t mention the leeches, which are everywhere.
Without human interference, the wildlife of Kaeng Krachan lives in total peace. The ecosystem rejuvenates itself.
An example: The staff at the national park headquarters decided to close an old logging road about 12km from the main gate at Sam Yot, securing it with a steel pipe barrier. No vehicles were allowed to enter this 9km road, which leads to important Huai Mae Sariang watershed. After about a month, I set 10 cameras along the road and nearby mineral licks. Tigers, leopards, elephants, gaur, sambar, serow, common muntjac, civet cats and porcupines made an appearance.
At one camera, four different leopards, three in yellow phase and one in the black phase, were camera-trapped. The next month, a mature leopard was caught at midday, and after that, a huge male tiger (shown in the main photograph) was captured on film. The road is now used mainly by wild creatures and forest rangers on patrol and in many places, the forest on either side has grown together.
The DNP should be commended for cleaning up the park while the road was closed. At Ban Krang ranger station alone, they collected hundreds of rubbish bags full of trash thrown into the bush by visitors.
The department has also set new regulations for visitors. Other than the headquarters area down the mountains, camping is allowed only at Ban Krang. Only day trips to Phanern Thung and Thor Thip waterfalls are allowed, and a forest ranger must accompany the visitors.
Without doubt, these measures will help Kaeng Krachan’s natural ecosystem. Due to the recent heavy rains, the park is closed once again until the beginning of the dry season next month.
These camera-trap programs have barely scratched the surface of the park’s full potential. There are still many species that surely survive in the interior. Further research and surveys should be carried out by the department to determine the diversity of this great forest.
Photo captions: The tiger, the leopard and the Fea’s muntjac are just a few examples of predators and prey that venture out on the park’s road while it is closed to tourists.
