Dinh Quan knows just the right spot to hang out on a warm day.

preferably with vines hanging within easy reach and showing no signs of
being poisonous.
Tailing behind Dinh Quan is his junior, Bien Dong, which means “South Sea”
in Vietnamese. He is learning the ropes of jungle living from his senior
who is at least 15 years old.
The two tusk buddies are wild Asian elephants living in the Dong Nai
Biosphere Reserve, a conservation area in Vietnam which includes the Cat
Tien National Park, and where an innovative project using “camera traps” is
under way to create a unique catalogue of “elephant ID cards” for the
area’s much-diminished population of pachyderms.
Pruthu Fernando, chairman of the Sri Lanka-based Centre for Conservation
and Research, told Al Jazeera that unlike human society where age and
experience confer a degree of respect, among elephants it is size and body
mass that decides their social hierarchy.
Fernando, who is an adviser to the United States-based Humane Society
International (HSI), said that when elephants reach puberty, at
approximately 10 years of age, they drift from the near-constant care of
their mothers to join other male elephants in social groups.
That is why Bien Dong and Dinh Quan had buddied up and how a photo of the
two trundling towards a waterhole was caught by motion sensor cameras in
April. The cameras are part of an elephant conservation project spearheaded
by HSI’s Vietnam chapter and local authorities in southern Dong Nai
province.
“This is the only project in Vietnam when it comes to elephants, which
provides elephant ID cards for each individual,” Nguyen Thi Mai, senior
wildlife programme manager at HSI Vietnam, told Al Jazeera.
“No one else has done this,” Mai said of the 60 “camera traps” operating in
the Dong Nai conservation area, which is located approximately two hours’
drive from Vietnam’s business capital Ho Chi Minh City.
The cameras, inconspicuously attached to the trunks of trees along tracks
that animals use to traverse the forest, have sensors that activate when
large mammals, like Bien Dong and Dinh Quan, pass by.
Images from the cameras are then compiled to create a catalogue of the
park’s individual elephants using characteristics such as age, sex,
physical traits and their general condition as a means to track their
movement and feeding habits, and monitor their health and recovery times if
they have been injured or ill.

The HSI data compiled to create the unique “elephant ID cards” consists of
more than 16,000 images collected during approximately 400 days of camera
monitoring from June 2022 onwards.
Analysis of the photographic data appears to show that there are at least
27 elephants in the conservation area, a significant increase from the
previous estimate of 14 pachyderms that were thought to form the total
population.
The data also indicates that the herd of 27 is in good condition with an
average health index score higher than elephants found in Sri Lanka, a
country with a significantly larger elephant population and where they
inhabit 60 percent of the country’s total land area.
Experts caution, however, that more detailed data needs to be collected to
supplement the camera traps in Cat Tien to determine the precise size of
the elephant population.
That is no simple task.
HSI’s senior programme manager Mai has more than 15 years’ experience
working with wildlife in Vietnam, but even she has not yet seen any of Cat
Tien’s elusive elephants in the wild, despite working in the Dong Nai
region for four years.
Images from the camera traps are the closest that Mai has come to getting
acquainted with the animals in their natural habitat.
While camera traps focused on closely identifying elephants are new to
Vietnam, they have been used in other countries around the world, such as
Thailand, India and Tanzania, as well as elsewhere in Vietnam, but
primarily to monitor wild animals at large.
The importance of producing individual identity profiles for Vietnam’s
elephants is underscored by the situation nationally, where as few as 130
elephants are still believed to be living wild, a dramatic drop from an
estimated 2,000 animals thought to roam the countryside in the early 1980s.
That means that here in Dong Nai province, Dinh Quan and Bien Dong are
among Vietnam’s second largest herd of elephants, just behind Dak Lak
province in the country’s central highlands region, which has the largest
population.
Vietnam’s conservation efforts are limited by resources and expertise, so
the HSI camera traps help fill a knowledge gap about elephants while also
training local officials in their use, Tran Thi Hoa, the national
coordinator of Vietnam’s elephant conservation programme, told a workshop
on promoting human-elephant coexistence.
High on the coexistence and conservation agenda is the issue of protection,
in terms of protecting elephants and rural communities that share the same
habitats where elephants love to roam.
Elephants in Nghe An province and Dak Lak in the Central Highlands move
internationally across Vietnam’s remote borders with part of Laos and
Cambodia. In contrast, elephants in Dong Nai move internally within Vietnam.
One method used locally to prevent elephants from stomping out of the
national park and conservation area is electric fencing – a subject that
some Vietnamese and international experts were split on at last week’s
workshop.
Conflict between elephants and residents living near the protected forests
of Cat Tien has been reported on by local media over the years, with
whimsical headlines such as, “The whole commune lost food and sleep because
the Ong Bo knocked on the door.”
Ong Bo, which translates as Mr Bo, is a respectful nickname locals use to
refer to elephants who have visited their villages looking for tasty crops
and creating mischief.
To prevent those unwanted visits and to also keep humans out of where the
elephants roam, a 75km-long solar-powered electric fence encloses part of
the reserve.
Tran Dai Nang, a ranger who works for the Dong Nai Forest Protection
Department, said there have been hundreds of conflicts reported between
local people and the pachyderms in three communes alone in the province,
according to surveys conducted from 2020 to mid-2023.
In almost half of those human versus mammal conflicts, the people involved
screamed at the encroaching elephants, made loud noises to shoo the
elephants away, and in some cases, used bright lights to frighten the
animals while others threw sharp objects, and some alerted forest rangers
to act.
The least-used strategy was to calmly talk to the elephants and implore
them to leave.
Elephants need a certain amount of space and so do humans to carry out the
necessities of everyday life, said Nang, the forest ranger.
Residents need to understand that when elephants “come to visit” their
fields and other areas, they are not going to harm them, he said.
“They are only coming to hang out with us. But it is going to require a lot
of time to achieve” that understanding, he added.
On top of diminished living space due to the reduction and degradation of
natural forests in Vietnam, human and elephant conflicts arise – as in many
other countries – from other man-made causes: encroachment on forest
habitats, poor management of conflicts when they do arise between humans
and mammals, and elephant populations not being considered in land-use
planning.
Earlier this year, Vietnam’s government decided not to allow the
construction of a highway through the Dong Nai Biosphere Reserve following
opposition from the Dong Nai provincial government amid concerns over the
effects on the region’s biodiversity.
There may also be other signs of hope for reconciliation between the worlds
of humans and elephants in Vietnam.
A research study published in 2022 found that people living around the Dong
Nai Biosphere Reserve want to coexist with their elephant neighbours.
HSI’s programme manager Mai said she hopes the photos produced by the
camera traps will give the elephants identities, and that will provide a
better understanding of their “needs and habits” and how they are affected
by human behaviours.
The elephants need their voices heard, said Mai, adding, “They have the
right to speak and express their opinion.”
