The Global Goals and Asian Elephant Conservation

The 17 Sustainable Development Goals provide a blueprint to achieve a better and more sustainable future for people and the planet. In celebration of Earth Month, we broke down all 17 Global Goals to discover how each relates back to our mission to protect and conserve Asian elephants and their habitat.

Global Goal 1: No Poverty

In developing countries where elephants roam wild, like Sri Lanka, poverty and elephants can become intertwined. Small farmers can lose their entire livelihood overnight from an elephant raid, and an 8,000 pound animal walking through a farm can destroy everything in its path.

Finding ways for farmers to make a living alongside Asian elephants is key to the survival and success of both elephants and people. Our Coexistence Project studies both sides to develop innovative ways that farmers can maintain a steady income while living peacefully alongside wild Asian elephants.

The Sumatran Elephant: Human-Elephant Conflict, Habitat Use and Home Ranges

By Gaius Wilson

The Sumatran elephant (Elephas maximus sumatranus), found only on the island of Sumatra in Indonesia, is critically endangered according to the International Union for the Conservation of Nature (IUCN). The population is decreasing with approximately 1500 elephants left in the wild in fragmented populations. Deforestation, loss of habitat and poaching for ivory are amongst the major threats to the survival of this species.

The Leuser Ecosystem (which forms a significant part of the UNESCO World Heritage site ‘Tropical Rainforest Heritage of Sumatra’) and Ulu Masen in Aceh, Sumatra are a stronghold for the critically endangered Sumatran elephant and other critically endangered wildlife (e.g. orangutans, rhinoceros, and tigers). Both Leuser and Ulu Masen are essential for the survival and conservation of the Sumatran elephant, but much of their habitat falls outside the protected areas and in the most threatened lowland forests, creating elephant human contact. This makes it critical that effective mitigation strategies are developed that take into account elephant behaviour and the use of technology such as early warning systems to reduce conflict with the local communities.

Can Asian elephants use water as a tool?

By Dr. Lisa P. Barrett

Asian elephants at the Oklahoma City Zoo

The floating object task is a puzzle that comparative cognition researchers present to animals (including humans) to study the evolution of cognitive abilities, like cause and effect understanding and the ability to use water as a tool. To solve the task and retrieve the floating reward inside, you must add water to a tube to raise the water level and reach the reward. Some primates, like orangutans have been able to solve the task by carrying water in their mouths from a drinker and spitting it into the tube to reach a peanut.

My colleague, Dr. Sarah Benson-Amram, and I presented this puzzle to elephants for the first time (Barrett & Benson-Amram, 2020). We wanted to see if elephants’ unique trunk morphology would make them well-equipped for the floating object task. Since they spray water for bathing, and hold water in their trunk as a vessel for bringing it to their mouth, we predicted that they would be up for the task. We collaborated with the National Zoo and the Oklahoma City Zoo to carry out this research. We used a tube filled about 1/3 of the way with water, baited with a floating marshmallow. As is often the case with animal research, things did not go as we expected.

Deja Vu at Dahaiyagala

by SdS

Elephants at the Pokunutenna reservoir.

When we saw the destruction, we felt that strange sensation of history repeating. We’d been here before, a little over ten years ago.

Dahaiyagala sanctuary is a little-known, nondescript little strip of forest north of Udawalawe National Park, one of the two official “corridors” that supposedly links the park to the outside world. It is supposed to lead to another forest area, which conservationists and wildlife authorities refer to as Bogahapattiya. It also borders Pokunutenna village, a hotbed of unrest with respect to human-elephant conflict. Dahaiyagala represents unfinished business to the various parties, in very different ways.

A Christmas Wish

By USW

Back in 2004, a male calf was born to the young female elephant, 458. The calf had baby tusks and this made his birth all the more special. He was named Therapuththa, or T458. We named him Therapuththa but labeled him as T458, following his mother’s ID, this is because it helps us keep track of him in the future when we catalog his movements, features and characteristics. His name, Therapuththa, was taken from ancient history: it is said that King Dutugemunu had 10 giant warriors protecting him and Therapuththa was one of the most loyal and endearing ones. The mother, 458, was often spotted with two other female elephants, who we have labelled as 040 and 041. After tracking this herd for so many years, we have unfortunately not seen any calves after Therapuththa. So he was quite special, besides being a tusker, which is rare in Sri Lanka.

Bees are Helping Thailand’s Elephants and Farmers to Peacefully Coexist – Bee Fences in Asia Part 2

A new study brings hope for reducing conflicts between elephants and farmers in Thailand

Guest post by Antoinette van de Water

Kaeng Hang Maeo district in Eastern Thailand is in an area of high human-elephant conflict. A herd of about 70–80 elephants lives between the protected areas and agricultural land, causing damage to crops almost on a nightly basis. Over four years ago, Bring The Elephant Home (BTEH) and the Phuluang Wildlife Research Station started a joint project to evaluate the effectiveness of beehive fences in deterring Asian elephants, under supervision of Dr. Lucy King. We set up a pilot beehive fence around a subsistence farm surrounded by elephant habitat and installed camera-traps to record the elephants’ reactions to the bees, which belong the species Apis mellifera, or European honeybee.

Can bees help farmers in Sri Lanka deter elephants from their crops? Bee fences in Asia – Part 1.

The tiny bee vs. the world’s largest land mammal…

Over a decade ago now, Dr. Lucy King developed the beehive fence as an elephant deterrent, capitalising on a then-recent discovery that African elephants avoided African honeybees (Vollrath & Douglas-Hamilton, 2002). The beehive fence is a relatively simple, inexpensive deterrent, aiming to be a tool that communities can use independently following set-up. The basic premise is that a series of beehives surround an area to be protected from elephants, and if elephants attempt to enter, they will disturb the beehives, causing the colonies to swarm (refer to King et al. 2009; 2017 for more details). It should come as no surprise, that the success of multiple beehive fence trials in Africa, led to a curiosity as to whether this technique could also help Asian communities experiencing comparable levels of crop-raiding.

Responsible Tourism & Ethical Elephant Experiences

Mother and calf - ethical tourismOn World Elephant Day, Trunks & Leaves is challenging travelers and travel companies alike to commit to responsible tourism practices when it comes to viewing and interacting with Asian elephants.

 For the first time in recent history, the world has slowed down, the travel industry is on hold, and humankind has a chance to reflect on the way we’re doing things and how we can improve in the future – for both humans and wildlife.

Explosive Food and What it Tells Us About Ourselves

By SdS

Somewhere, there is a hungry elephant, following her nose, wandering an ever-diminishing forest in search of food. She ventures to her usual places, finds them lacking. She wanders further from where she feels safe, considering what she may find closer to the villages nearby.

Somewhere there is a hungry person. Perhaps a farmer, perhaps a hunter. He is looking to drive away pests from his land, or maybe to earn a bit of money from bushmeat. He selects a large fruit or vegetable, say a pumpkin or pineapple. He hollows it out, hides an improvised explosive inside, leaves it where some animal will find it.

We know what happens next. Continue reading

Baby tantrums

We’ve temporarily halted field work due to the pandemic. So, we thought this was a good time to bring you some stories from our archives of field notes! In honor of Mother’s Day, here’s an incident that helped us appreciate just how little we understand about what goes on beneath the surface of an elephant’s mind. Happy Mother’s Day!

Can you tell what’s going on in this video? Well, if you know the elephants individually, there’s quite an intriguing story behind it. Read on to see what’s happening, and see if you can follow the video…
