Shared History Ties Humans and Elephants: A Tale of Two Nations

By Sateesh Venkatesh – PhD student, UCSD

The air is fresh, there is a light dew on the leaves, and the first shafts of the morning sun pierce the tree cover as our team heads out to the field. These calm mornings in the field typically start the same way, but they disguise the complexity and challenges faced at night by many of the farmers we are off to meet. Mornings for these farmers mean an interlude between nights spent defending their crops from elephants and days of hard work maximizing the production of the same crops.

My research covers two locations with remarkably similar problems, even though an ocean separates them. Outside of Thailand’s Kui Buri National Park, farmers spend their mornings preparing pineapple fields for harvest, while across the Indian Ocean in Sri Lanka, farmers near Udawalawe National Park set out to monitor a variety of different crops. Though separated by thousands of miles, these communities share a common challenge: finding ways to thrive alongside Asian elephants in an increasingly crowded landscape.

As an elephant researcher working across these two distinct regions, I have a unique opportunity to compare how variations in historical contexts and cultural structures shape human-elephant interactions in real-time. While most scientific studies rely on comparing methods and results from published literature, our research teams simultaneously monitor these two sites to understand better how anthropogenic change, climatic variation, and regional stressors impact the complex and changing relationship between humans and elephants.  

Research Sites and Local Partnerships

Our research spans two carefully selected field sites, each offering distinct insights into how humans and elephants are currently co-existing. In Sri Lanka, we work at a site established by Dr. Shermin de Silva in 2006, situated just outside Udawalawe National Park, which covers 308km2. Our Thailand field site borders Kui Buri National Park – a protected area more than three times larger at 969km2 – where our partners at Bring The Elephant Home (BTEH) have built strong community relationships over two decades. In both locations, Asian elephants and humans share resources, particularly in agricultural areas, but the historical context of these interactions varies dramatically.

A Tale of Two Histories

In Sri Lanka’s Udawalawe area, people have farmed alongside elephants for generations. The construction of the Udawalawe reservoir in 1972 led to the establishment of the national park. The area that became the park had primarily been a teak plantation rather than farmland, which meant that establishing the protected area didn’t require relocating large areas of farming communities – as can often be the case. The farmers who live around the park’s edges today are largely from families who have traditionally farmed the surrounding lands for generations, maintaining their agricultural practices and long history of living in proximity to elephants. 

In contrast, Ruam Thai Village in Thailand represents a more recent human settlement. Established in the 1970s through a government initiative, the village brought together people from across Thailand to create a new community focused primarily on pineapple cultivation, two decades before the area would be designated as Kui Buri National Park in 1999. The crop’s high international market value made it economically attractive, and it also drew interest from local elephants. The tragic deaths of two elephants from poisoning and gunshot wounds in the late 1990s prompted His Majesty the King of Thailand to establish Kui Buri as a protected area specifically for elephant conservation. However, recent research by the  Udawalawe Elephant Research Project (UWERP) and Trunks & Leaves team has revealed that elephants in both locations typically spend only about 50% of their time within national park boundaries, highlighting the critical importance of understanding and supporting coexistence in the surrounding landscapes. (See Annie’s blog on How Elephants in Sri Lanka Use Protected Areas here.)

These different historical trajectories have shaped distinct landscape patterns. Sri Lankan farms form a patchwork of individual plots interspersed with houses and fragments of forest, reflecting generations of land division and management. Ruam Thai’s layout is more structured, with a centralized residential area separated from a consolidated farming zone that borders the protected area. 

Elephant Memory and Cultural Heritage

Over an elephant’s 60-year lifespan, they build up an extensive catalog of experience across a vast landscape. Due to the social complexity of elephant culture individual experiences become part of a vast assemblage of experiential knowledge that crosses generations. We’re discovering that elephant populations may develop distinct “cultures” influenced by their interactions with human communities over generations. In Sri Lanka, for instance, elephant family groups demonstrate sophisticated knowledge of traditional movement corridors that predate current human settlements. Meanwhile, in this area of Thailand, elephants show different patterns of adaptation to the more recently established agricultural landscape. 

The concept of generational learning adds another layer to this complex relationship. Like humans, elephants can pass on behavioral responses to past experiences. In both locations, we’re observing how historical interactions influence current elephant behavior and how these learned responses might be transmitted to younger generations. 

Pathways to Harmonious Coexistence

While the challenges in each location are unique, our ultimate goal remains constant: creating environments where both humans and elephants can thrive together. In Sri Lanka, this means building upon generations of traditional knowledge about elephant movement patterns. In Thailand, it involves developing new strategies that account for the more recent nature of human-elephant interactions. 

Current initiatives in both locations show promise. Sri Lankan farmers are experimenting with crops less appealing to elephants that will allow them to use the same land, while maintaining historic elephant pathways through their lands. In Thailand, community-led initiatives in high-conflict areas are exploring converting pineapple fields to organic alternative crops that will reduce conflict and improve healthy farming.  

Looking Ahead

As our research continues, we’re working to understand what successful coexistence looks like in these different contexts. Can the traditional knowledge of Sri Lankan communities inform new approaches in Thailand? Might Thailand’s community-centered development model offer insights for Sri Lankan villages? By studying these questions across two distinct cultural and historical settings, we hope to develop more nuanced and effective approaches to fostering positive human-elephant relationships. 

The path to harmonious coexistence requires patience and understanding, but studying the shared histories of humans and elephants in each landscape provides crucial insights for future conservation efforts. As we continue our research, one thing becomes clear: successful conservation strategies must honor both the human and elephant histories that shape each unique landscape. 

New pan-Indian study of elephant genetics reveals surprises

Herd of elephants in Terai Arc Landscape

Asian elephants were once widely distributed in India, but are now restricted to four widely separated regions: the north-western (NW), north-eastern (NE), east-central (ECI), and the southern India (SI). When you undertake the population genetics study of a wildlife species, the quality of the result is related to the design of the field sampling protocol. This is to ensure that the sampling is extensive covering different areas to avoid over-sampling of more accessible populations. When we started our population genetics study of the Asian elephant (Elephas maximus L.), we planned to collect fresh elephant dung samples from across the beats and various ranges of protected forests in India. This of course often involved traversing through inhospitable and difficult terrain with a forest staff in attendance. The first problem were the elephants themselves. To get fresh dung, one had to go close to elephants for collecting samples. This often did not go down too well with some individuals who responded to the invasion by a determined charge. We were fortunate not to have suffered any mishaps and ultimately it worked out well and we were able to collate an impressive database of elephant dung samples.

Camera Trapping Elephants in Agricultural Areas

In partnership with Bring The Elephant Home in Thailand, we’re excited to share this picture diary from the field, by Brooke Friswold, who is a PhD student at King Mongkut University of Technology Thonburi!


Written by Brooke Friswold

It has been another busy month in Ruam Thai Village! We have erected ten camera traps on pineapple farms with the consent of local farmers in areas with reported high frequency of visitation and five on lemongrass farmland rented by Bring the Elephant Home.

In speaking with the farmers they were very excited and enthusiastic to share their experience: some of the farmers say that the elephants are coming most nights to their land, while others say it can be weekly or also come in waves, with times of high visitation followed by lapses in appearance. The farmers were very eager and interested to share and discuss where the best placement would be for the camera traps, the trails the elephants use to enter, and the recent visitations they had.

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.

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.

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.

When farmers and elephants compete for space

By Lena Coker

These farmers in Sri Lanka are at the interface of forest and agriculture, where most incursions by elephants occur.

In Sherpur, rural Bangladesh, as the human population increases, so does the demand for the land and natural resources that the elephants need to survive. This is a story of human-animal conflict that is repeated around the globe with many species and rural communities as they struggle to find the balance for coexistence. Continue reading

Call Combinations Differ Among Living Elephants

The living elephants – Asian elephant, African forest elephant and African savannah elephant.

Guest post by Michael Pardo

Ask most people what sound an elephant makes and they are likely to think of a trumpet. In reality though, elephants produce an incredible variety of different vocalizations. The most common call is a deep, pulsating rumble, so low-pitched that human observers sometimes feel it more than hear it. Elephants also roar—powerful, bellowing sounds that carry across the landscape. And sometimes, they give combination calls, in which one or two rumbles and roars are stitched together with no pause for breath.

I visited Udawalawe in 2014 to work with the Udawalawe Elephant Research Project, and was especially fascinated by these combination calls. Combining meaningful units into sequences with an additional meaning is a key component of human language, but there are relatively few examples of this phenomenon in other species. Listening to the Udawalawe elephants, I was struck by the fact that they nearly always produced combination calls in the same order: a single roar followed by a single rumble. Why was this? Could it be analogous to grammatical rules in human language? Or could it be as simple as an anatomical constraint that made it difficult for the elephants to produce a rumble before a roar?

The Patels Visit Udawalawe

Guest post by Yogi & Nikita Patel

We traveled to Sri Lanka to work with Trunks & Leaves in support of schools surrounding the Udawalawe National Park. We first arrived in Negombo, Sri Lanka where we were met by Deepani, who works with Trunks & Leaves, and her friend Jocelyn. We traveled by car to Udawalawe where we were joined by Sameera, the project coordinator. We visited the first Montessori preschool, operated by Sameera’s sister, Chathurika. She was gracious in showing us the school, which was closed for the holidays. She had been hard at work painting furniture and cleaning the classroom and play area for her 18 students. Her school, which is attached to her home, is surrounded by many fruit trees. Her family members supported her passion for educating children in her town.

Our next stop was school teacher Shiromi’s home. We met with Shiromi who greeted us with her family and offered the most amazing homecooked treats. We chatted about her work in the village and her school, Dimuthu preschool. We met with Shiromi again the following day, where we observed the children in her classroom. The parents were very supportive of Shiromi and came to the school with their children even though they were supposed to be on holiday. We got to sing and dance the “hokey pokey”.

India includes some of the largest populations of Asian elephants in the world: an estimated ~26 000 to 28 000 elephants distributed across four regions. Of the four regions, southern India includes the single largest population of Asian elephants in the world (~14 000) and elephants are distributed across the Western and Eastern Ghats.

I studied the ecology and behaviour of Asian elephants as part of an ongoing long-term project on elephants, the Kabini Elephant Project, which was started in March 2009 to study the social life of elephants. Continue reading
