Increasingly dangerous environment for wild elephants: An indicator species of a pristine forest
Of all the mammals in Thailand, the wild elephant is probably the most important indicator species of a disappearing wilderness. A century ago, there were more than a hundred thousand elephants found in the country when 75 percent of the Kingdom was still covered by forest. Just north and east of Bangkok, these huge mammals thrived in the marshlands and forests near the city.
But as time passed and humanity expanded creating cities and towns, roads and highways, railways, agriculture farmlands, golf courses and resorts, the home of the wild elephant began to disappear leaving many forests fragmentized and degraded. Populations of wild elephants went into serious decline. Humans are directly responsible for this loss with encroachment and poaching at the forefront. Forests and wildlife continue to disappear as we move into the 21st Century.
When Khao Yai, the first national park in Thailand was established in 1962, the Royal Forest Department (RFD) was in charge of protecting the forest. Prior to that, they controlled logging concessions and huge swathes of forest were felled in the timber business. Finally, the government stopped all logging in 1989. However, illegal tree felling is still going on to this day but on a smaller scale.

Then in 1992, the Department of National Parks (DNP) was established to look after the national parks, wildlife sanctuaries, non-hunting areas and marine national parks. There are now over two hundred protected areas nation-wide.
Since then, it has taken many, many years for the department to establish some form of protection and enforcement. Patrolling of the forests has been minimal due to many factors. Unfortunately, things have been difficult for them to look after these biospheres because of low budgets and not enough personnel. Laws are seriously outdated especially when it comes to elephants.

The history of man and elephants in Asia has been intertwined for several thousand years. These majestic creatures taken from the wild have been part of human culture and beliefs. Elephants played a major role in the wars with Burma of the past. Until recently, the elephant was not only used for logging but for transport and baggage. More recently, they are used to attract tourists at camps and in cities where people use them for begging. The domestic elephant has been abused, and very badly in some cases.
Begging elephant in Chiang Mai – Abstract.
Probably the most appalling fate for a domesticated elephant is to become a streetwalker. These magnificent creatures are forced to walk hot, dusty and polluted streets of Thai cities ‘begging’ for food and money. Stories about elephants hit by cars and falling into drainage ditches, plus other accidents have been documented.
Ten years ago, it was guesstimated that 2,000 wild and 3,000 domestic elephants were thriving in the country. Due to an increased DNP and NGO interaction in the parks and sanctuaries, wild elephants have made a bit of a comeback in some protected areas. There are now (still guesstimated) to be about 3,000 wild elephants and more than 4,000 domesticated animals. Population density surveys have been carried out in some parks but exact numbers of the wild population are still uncertain.

The biggest threat to wild elephants is still the same. Poaching males for their ivory and females for their babies. Recent kills in Kaeng Krachan National Park in the Southwest have gone on for quite sometime due to poor protection and enforcement, and numbers of elephants have dropped.
Elephants in the savanna of Kui Buri National Park.
It is quite possible that they have migrated to Kui Buri National Park further south along a thin corridor along the Burmese border. Numbers in Kui Buri have increased 100 percent in the last five to ten years, and evidence of elephants in Prak Tha Kor Reserve Forest between the two parks has been documented. This area needs to be established as a protected area.
Elephant herd in Kui Buri National Park.
The following is a typical scenario of baby elephant snatching. Gunshots reverberate explosively through the forest, panicking and scattering a herd of wild elephants. The huge beasts instinctively flee as fast as they can through heavy foliage away from the cacophony. In minutes, the forest returns to normal. But the sad fact is that humans have just disrupted the herd permanently.

A baby elephant mills aimlessly around its mother lying dead on the ground. The confused calf has no sense of danger as poachers move in to capture it to be sold on the illegal black market. The calf will likely be forced to wander city streets or work in tourist camps.

Such atrocities are still practiced by unscrupulous people intent on killing the mother solely to capture the baby. Many other animals are also hunted down in much the same way. Middleman, the ‘big-fish’ and end-use buyers perpetuate this market and seem to evade the law. When will this horror story ever stop?
A tusker and tourists in Khao Yai.
In another real-life scenario, a young tusker is killed on the road that transects the northern part of the elephant’s range in Khao Ang Rue Nai Wildlife Sanctuary in eastern Thailand. It is home to about 170 wild elephants. The road had been widened and resurfaced to enable faster speed.

During late-evening one day in May 2002, a man and woman in a pickup truck barreling through the sanctuary at high speed did not see the elephants on the road until it was too late. The truck crashed head-on into a 5-year-old tusker. The truck’s driver was killed on impact but the woman survived. The young elephant died shortly after.

This young tusker was not the first and definitely will not be the last elephant to be killed by reckless driving on this road. Eventually, the local government ordered the road closed through Khao Ang Rue Nai from 9pm to 5am. The elephants come out of the forest usually only at night and can now roam safely in their own habitat. Accidents and road-kill have dropped drastically. Definitely a role model for other protected areas with elephant-human conflicts.

Such accidents are a terrible blow to the conservation of Thai elephants, because tuskers are particularly vulnerable, being subject to hunting for their ivory. Asian ivory is finer-grained than African ivory and prized for carving into trinkets and Japanese hanko (signature seals).
Herd in Kui Buri N.P.
Much of their habitat has been taken over, mainly by pineapple, sugarcane and cassava. Villages spring up in old elephant habitat, and the trespassers expect the giants to simply fade away into the forest. But elephants can develop a taste for crops grown by farmers, and they often take what they want. Countless conflicts have arisen between villagers and the real owners of the land, whose ancestors have lived there for many thousands of years.

Elephants have been maimed and killed by poisoning waterholes, pungee stakes, gunshots, and electrocution. They have been chased out of rice paddies, mango orchards and farmlands. People use fireworks, bright lights and guns to scare them away temporarily, but the elephants are intelligent enough to lose their fear of such ruses.

These giants grow bolder and go on the rampage, sometimes killing people, tearing up villages and damaging RFD and DNP facilities. Some conservation organizations have erected new signs warning of the danger of elephants in the area.

A trip at night around some cities, one can still be greeted by a huge gray beast with a red light attached to its tail. Continuous calls for change go unnoticed by mahouts and the owners of these elephants who sneak them into tourist sites. Legislation concerning domesticated elephants remains old and out-dated, and law enforcement has also been very poor. On the positive side of things, the authorities have finally moved them out of Bangkok, but they still roam on the outskirts in some places.

It is hoped that the RFD, DNP and other government organizations will draw attention to the dire situation of Thai elephants, both wild and domestic. These noble beasts have featured prominently in almost every important historical event in the Kingdom. They are a national symbol of pride and joy. The Thai elephants’ future survival lies in the hands of the government who are responsible for these amazing giants….!
I would like to thank Andy Merk, German wildlife photographer for the lead photograph. He has been hanging around Khao Yai for the last 20 some years and has a huge collection of elephant photos from the park. He is doing a survey of trying to get a estimate of the population by identifying individual elephants by their ears, specially the male tuskers and mature females.
Creatures on the log: A giant rodent, a pitta and an eagle
Not much passed over the dead tree last month but I did get a few interesting creatures that stopped by. The Nikon D700/35mm lens/ML-3/Pelican 1150 with three Nikon SB-28s worked very well. An Asiatic porcupine crossed over, and a blue-winged pitta and then a changeable hawk-eagle with prey landed on the log. Due to the 35mm lens, it seems a bit wide with the full-frame sensor and had to crop these images. I will be putting a 50mm when I get back to the unit next month…in the meantime, the cam is working very well and looking forward to those big cats with stripes and spots….!

Recently, I pulled a Sony W30 camera trap from a mineral deposit in the Western Forest Complex and found some amazing photos of a mother tiger and her two cubs. It is very rare to see a tiger family on a trail cam. These amazing creatures usually do not hang around when it starts flashing at them…but I got some great shots shown here.

Banteng have now become quite rare in Southeast Asia but thrive in two wildlife sanctuaries in Thailand; one in the east and one in the west. Here are some shots of these beautiful wild cattle. The old bull looks like he is having a heck of time with the moths.

Awhile back, one of the members on Camtrapper.com forum (zaj56) posted on June 22, 2013 ‘some bear pics’ and had forgotten to put a memory card in his cam but the internal memory (10 shots) was able to get some very nice bear shots.

Going through my S600s recently fixing on/off switches (just posted on the forum), I found some shots on the internal memory from November 2012 on one cam and decided to have a closer look.

Imagine my surprise when I saw 10 shots including a tiger and leopard close to the cam. This means I had forgotten to put a memory card in the cam and just lucked out getting the two big cats.

The moral of this blurb: Try not to forget your memory card before deploying the cam…!
The single most aggravating thing about Sony S600s is the on-off button. These cams are really one of the best for homebrew trail camera traps and I really enjoy using them. For some reason the switch tends to bottom out and the cam cannot be turned on. I have seen so many where someone previously used their fingernail to turn it on and off, and after awhile it just collapses and will not work.
Sony S600 on-off switch repair
I like to turn my S600s on before deploying in the forest to check the time, date and other things like mode, ISO, flash on, etc, and trying to turn it on with the sensor can be iffy. There is not enough time to check anything before the sensor tells the cam to shut down…!
Solder points for switch repair
All the Sony P and W-series cams usually do not have this problem and even the S40 button is good. As most of my 600s had this problem, I came up with a simple trick to fix this. A small push-button switch and short wire is soldered onto the pad as shown in the photos. Run the wire through the buttonhole and ‘Goop’ in place. I have now fixed all my S600s like this and they are working very well.
Hope this helps those on the forum with this S600 affliction.
A new/old Canon 400D: An easy DSLR in cost and production
Canon 400D with battery grip/Pelican 1150/Snapshot Sniper SSII board/Yongnuo wireless flash trigger plus two ‘D’ cell externals.
Back in march 2012, I built and posted my first DSLR trail cam around a Canon 400D with 18-55mm kit-lens and a Yeticam board (EOS chip) in an old recycled aluminum box I had made up for Minolta 800 si SLR film camera years ago.
I was using Yongnuo wireless flash triggers tripping three Canon 270EX flashes and it was working OK when I left it. Elephants bashed the thin-tube aluminum snorkel breaking the front glass, and then it rained. And that was that…!

I then picked up a Canon 350D with the 18-55 kit-lens and got another Yeti board rebuilding the cam. The snorkel was busted again by the forest giants but it did not rain this time and I was able to get it going again with a new replacement glass (77mm UV filter) and an ‘elephant proof’ snorkel protector. This cam is presently working very close to where I camera trapped and was charged by a bull guar.

I decided to buy a second-hand Canon 400D (Rebel XT-i) body only but this time went with a fixed Canon 50mm ƒ1.8 lens. I picked up a Pelican 1150 box and one of Snapshot Sniper SSII #5 boards and hooked it up with a Canon shutter release (button removed and it has a good 90-degree plug). A 77mm aluminum tube and filter is glued to the case with Goop. A Snapshot Sniper HPWA with a black Fresnel is used with the sniper board.
Canon 400D ready for the field.
The shutter release shielded wire is ground and white is shutter and red is power. The camera is set to ‘Continuous’ and the board to trail mode. I’m getting 5-6 frames per trip and can trip as many as four-five flashes at once. I have several different locations planned for this cam. With a Yongnuo 603C wireless flash trigger with two ‘D’ cell externals and everything fits nicely in the 1150.
Flashes to be used with the Canon 400D.
I have two recycled flashes (a Canon 270EX and a Nikon SB-28) that will make up the group. Another two Nikon SB-26s on ‘stand-by’ mode will also be put into service (one with four ‘C’ cells and one with four ‘D’ cells) to see how long the respective batteries will last. A special modification is made to the SB-26s to allow regular 6-volt 4-cell packs to be used. Another mod is to unhook the ribbon to the monitor after the flash has been set-up (mostly half-power). This will reduce power consumption on the SB-26s.
Nikon SB-26s: one with four ‘C’ cells and one with four ‘D’ cells.
The Canon 400D (300, 350 or 450Ds) are not that big or expensive. There is plenty of room for a pipe through and Python locking cable. It will shoot in ‘Raw’ mode that will allow some latitude in post-processing.
As usual, I have made up an elephant proof aluminum box that will be bolted to a tree with three 3”x 3/8” stainless lag bolts from inside the box plus two 10mm Python cables. The front cover is bolted to the box using six 10mm power-torque machine screws. The flashes are in aluminum boxes with 8mm power-torque machine screws bolted to trees with the same lag bolts and Python locking cables for security.

I have another 400D that will be getting the same treatment except I have an adapter to use an old Nikon 50 ƒ1.4 manual lens. We will see what the difference is in using a plastic lens versus a glass lens. I’ll put my money on the glass out-preforming the plastic…!!
Cost of materials – cost can vary:
Canon 400D………………………………………………….. about $150 (used)
Battery pack grip……………………………………………… about $32 (new)
Canon fixed lens 50ƒ1.8 ……………………………… about $80-90 (used)
Canon Shutter release……………………………………………….. $13 (used)
Pelican 1150 case……………..……………………………………….. $30 (new)
Yonguo 603c flash triggers (a pair)……………………………… $33 (new)
Snapshot Sniper SSII board (#5 chip) & HPWA Fresnel.. $50 (new)
Total cost: about $398 plus labor and essentials (Goop, extra cam battery, drill bits, soldering tools, etc).
Hope this will give some of you camera trappers out there an incentive to build a DSLR…! The cost for some cams is not that expensive and the Canon 400D is a good choice for a first cam.
