One of Thailand’s most famous protected areas,
particularly for tigers, is Huai Kha Khaeng Wildlife Sanctuary (HKK). Over the
past twenty years, this world heritage site has received considerable
conservation support from both the Thai government and international NGOs. Long
term studies have shown the area has a healthy population of tigers (~70
individuals) with the potential for the sanctuary to restore populations across
the western forest complex of Thailand. With recovery of prey species and
continued protection, it is believed this area of Thailand could support up to
2000 tigers; with an estimated total population of 3,200 wild tigers in all of
Asia, this area is a key part of protecting tigers from extinction and
recovering populations in south and south-east Asia.

Since HKK is a wildlife sanctuary, the park is not
typically open for tourists. However, I was fortunate enough to be invited on a
3-day tour with FREELAND and park staff from elsewhere in Thailand. It was a
great learning opportunity to see how effective conservation investment has
translated into success, what problems the area currently faces, and how the
park and its allies plan to address them.

Watch out for tigers! |
Upon entering the park, one of the first things I
noticed was the charred forest floor in some areas. I suspected that the park
was using fire as part of its management strategy, a suspicion confirmed by my
FREELAND colleague and the presence of park staff watching over several fires
burning along the entrance road. Given
that the park was baking in the height of the dry season, I was somewhat
nervous that the fire could spread to other parts of the park and become
uncontrollable. Management uses these fires as a means to increase grassland,
favourable to ungulates (hooved animals) and the carnivores than prey upon them
(tigers and leopards). It’s a controversial strategy; fire is a natural
occurrence, but abuse could prove destructive.

Another curious element of the park was the
presence of rare or non-typical species of deer such as Eld’s and hog deer. I
knew something was unique about them not only because they had tags and
electronic collars, but also because they hovered extremely close to the guest
houses, paying little mind to the guests. I learned these deer were introduced
from captivity in order to bolster prey species for the park’s carnivores.
Unfortunately, I also learned that these individuals were less predator-savvy
than their wild counterparts and have become easy meals for leopards. This
explained why, underneath the guest houses, scores of hoof-prints could be seen
in the sand; deer were using human shelter to protect themselves at night from
becoming cat food. It’s one of those projects that is great in theory, but is
definitely a work in progress.

On the first night, we viewed presentations by the
park chief and assistant chief, outlining the history of the park as well as
some of the scientific research that has shed light on the park’s wildlife. The
park is one of the most biologically diverse areas of Thailand. The region’s
diversity is exceptionally high because, in addition to its high habitat
diversity, it occupies a unique position at the junction of the four
biogeographic zones of mainland South-East Asia. Many species reach the
north, south, east or western limit of their range within its boundaries and do
not occur together in any other area.

Although I couldn’t completely understand some of
the conversations, I was impressed by how the park chief conducted himself. He
seemed eager to share information with his guests and his body language
suggested he has a passion for maintaining the high reputation of the park;
however, he also spent some time asking questions and getting feedback. The
chief seemed quite committed to conservation and aware of the importance and
responsibilities of his position. He eagerly handed his card to me – for what
reason, I am not sure, as I clearly am not an important conservation figure –
but the gesture was appreciated and was indicative of his desire to remain open
to networking with other groups.

The next day, myself and my colleagues had the
great fortune of observing a monthly ranger patrol meeting with Dr. Anak Pattanavibool,
development director and significant HKK research figure from the Wildlife
Conservation Society in Thailand. Park management attended to view multi-media
reports from rangers on patrol results over the past month under the Smart
Patrol program. These presentations highlighted ranger activities and
observations on the various threats to the park. It was interesting to see how
organized and professional the rangers were at communicating their work;
although I didn’t fully understand the presentations, I was able to gain a
general understanding of the work that is being done on the ground. Afterwards,
the rangers split into groups to hold strategic planning meetings for the month
ahead, particularly to address pressing threats such as poaching and
encroachment.

Afterwards, I spent some time on my own walking
through the forest, trying to find leopard or tiger tracks, but to no avail. I
joined my colleagues on an afternoon trip to an observation tower near an open
forest field. During our arrival, I was able to see several nervous banteng (a
rare cow-like animal and tiger prey species), slip into the forest out of view.
As the sun began its slow descent behind western mountains, the group sat in
silence, straining to hear or see any signs of wildlife. Hundreds of meters
away, I could barely make out the dish-like form of a peacock advertising its
colourful feathers to any nearby females and I was able to spot a group of
jungle fowl grazing by the river. Fortunately, our patience and silence paid
off as the banteng we had initially scared off returned to the field to graze.
The group included a female and two large, macho-looking males. It seemed as
though they were attempted to court her, though the larger of the two monopolized
her attention. Fresh wounds on both suggested they were quite serious about
establishing mating rights.

As the larger of the two males strutted onto the
field, it dug its head into the dirt and tossed it upwards, producing a large
cloud. Whether this was to show its strength or free itself from the burden of
bugs, I am not sure, but it was an impressive display. He hovered over the
female imposingly and would occasionally cast an intimidating gaze in our
direction. We weren’t as covert as we had thought, but the banteng seemed
content with the large distance that separated us. I found myself astounded
that these massive bovids with such intimidating horns (along with gaur) could
be so frequently targeted by tigers as prey.

On our final day, one of our crew managed to
convince park staff to allow us entry deeper into the park and to a
particularly well-used tiger research station. On our way, we stopped
occasionally to check the dirt for tracks and, in one instance, we came across
the tracks of a leopard.

We eventually arrived at Kao Nangram
Wildlife Research Station. Here, we learned about the long history of tiger
research at Huai Kha Khaeng and how understanding of tigers in the park is
enriched by methods such as camera-trap sampling and radio-collaring. One of
the staff showed us some of the radio and satellite-collars that have been used
to track the park’s tigers and showed us recent data in Google Earth on where
tigers have been known to occur. Informed that tigers had been tracked nearby,
we were escorted by car to fresh tiger tracks and tiger scent marks, which
tigers use to advertise their territory. The scent left by the tiger was quite
fresh, a smell burned into my nostrils and memory from voluntary cleaning
duties at Jungle Cat World Zoo outside Toronto. It was quite exciting to know
that a tiger was so close and that we were in its territory.

Sadly, we had to eventually leave the park.
I was quite impressed and would have been happy to spend more time at HKK,
particularly at the research station. However, I have my own work to do with
FREELAND and don’t lament that fact one bit.
