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.

The first camera trap video we captured showed a small herd of elephants breaking through the newly installed fence. Since then, the team made several adjustments to improve the effectiveness: increasing the bee population, reducing the distance between the hives, and a low-cost trigger mechanism, which opens the hives to activate dormant bees when elephants try to break through the fence.

After spending many nights observing videos, we decided to set up a team of citizen scientists to help analyze videos. The results indicated that over 60% of the elephant groups and over 88% of the individual elephants were deterred by the beehive fence. The elephants that came close to the beehive fence showed typical signs of increased alertness and uncertainty and often slowly backed away. The farm owner reported a strong reduction in crop damage after the beehive fence was installed, as well as additional benefits including the supplemental income, pride, and skills development.

We further looked into the local communities’ attitudes towards elephants where the majority of households experienced negative encounters with elephants at least once a week including damage to crops and property. Although most farmers had not gained any benefit from living with elephants, two-thirds of the respondents reported being tolerant towards elephants, if only they would stop causing damage. This initial study indicated the need for solutions that combine elephant damage reduction with benefits for local people.

We always emphasize that beehive fencing is not a stand-alone solution. The method requires significant investment and may not work in every human-elephant conflict context. To maximize impact, beehive fences should be combined with other methods such as habitat restoration, providing access to benefits to local communities and growing crops that are unpalatable to elephants. For instance, the farm owner in this study started growing chilli and lemongrass along the beehive fence as an extra barrier, to attract bees, and as a source of income. After positive feedback from farmers, Bring The Elephant Home launched the Tom Yum project: named after the spicy, healthy Thai soup of which the ingredients (chilli, garlic, lemongrass, galangal, kaffir lime, onion, coriander) are not attractive to elephants. Like beehive fences, the Tom Yum project helps to diversify local livelihoods, create employment, and promote human-elephant coexistence.

Working on these positive projects provided a unique opportunity to learn about the complexity of HEC, fostering connections across the world, thus strengthening awareness and cooperation. It stimulated out of the box thinking, empowered farmers and showed potential ways forward to realize peaceful coexistence.

This study was a collaboration of Bring The Elephant Home Foundation, the Phuluang Wildlife Research Station, Project Dragonfly of Miami University, the Future for Nature Academy, the Elephants and Bees Project of Save the Elephants and global citizen scientists.

Editor’s Note: One of the important differences between this initiative and others in Asia is the use of non-native European honeybees rather than the native Asian honey bee, Apis cerana. The native honey bee is in decline in parts of Asia, and the potential risk of invasion by non-native bees is unknown, requiring further study.

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.

As part of Dr. King’s ‘Elephants and Bees’ project, I had the pleasure and challenge of testing beehive fences, in Dewagiriya Village, Sri Lanka. Dewagiriya is a small paddy-farming community of around 45 permanent households. It is located approximately ten kilometres from Wasgamuwa National Park which is home to more than 400 wild elephants. Elephants frequently venture outside the park, entering nearby villages to forage on crops, vegetables, and fruits. In Dewagiriya village, crop-raiding occurs year-round and community members struggle to protect their livelihoods and homes from nocturnal pachyderm visitors.

It is a unique experience turning up to a new community, to introduce the seemingly absurd idea of deterring elephants with bees. My only (very loose) connection to Dewagiriya was that the family of my field assistant’s best friend’s mother lived there. I was aware that as a female research student from middle-class, urban Australia, I was an outsider and a curiosity. I was also conscious that my textbook knowledge of human-elephant conflict in Sri Lanka was nothing compared to the lived experience of the Dewagiriya community, and that I had a lot to learn.

However, people were very welcoming and, feeling generally limited in their capacity to protect their crops from elephants, were keen to give beehive fencing a chance. I stressed that we did not know if the fences would help but expectations were high. Between 2014 and 2017, my small team of local and international field assistants and I worked with the Dewagiriya community and established Sri Lanka’s first beehive fence trial.

The community identified home gardens as particularly vulnerable to elephants, and we chose ten gardens to surround with beehive fences as well as ten ‘control’ gardens which remained unfenced. For three years, we recorded data on all elephant sightings and entries into home gardens, and on bee colonisations and hive health. Together, we built fences, fixed posts, monitored hives, and practised beekeeping. My talented, bi-lingual field assistant Supun translated back and forth as I learned about the challenges and joys of life in Dewagiriya Village, and specifically of co-existing (willingly or not) with elephants.

So, the big question: did beehive fencing effectively deter Asian elephants from crop-raiding (in Dewagiriya Village)?

Spoiler alert: there is no simple response.

The short answer is that the fences demonstrated effectiveness. Significantly less elephant incursions occurred at home gardens surrounded by beehive fences compared to control gardens, and this effect strengthened as hive occupations increased. This result was both exciting and encouraging. However, the question remains: was it enough? 43% of elephant approaches resulted in elephants entering home gardens, usually causing some damage, and creating danger for the family inside.

On reflection, (and in my personal opinion), two key barriers to beehive fence success in Dewagiriya Village stood out: (a) practical challenges of beekeeping; and (b) community motivation, willingness to participate and capacity.

Practical challenges of beekeeping

Prior to beginning our beehive fence trial, beekeeping was not common in Dewagiriya. A few elders harvested wild forest honey, and a couple of people used clay pots to attract wild bees. Overall, beekeeping was a learning curve. Teaching a new skill, at the same time as introducing a new elephant deterrent, in addition to the busy day-to-day lives farming and nights spent awake waiting for elephants, is a big ask.

Natural hive occupations were low, meaning colonies had to be purchased and transported from Kandy and Colombo, adding considerable expense to the fences. Our only option was to use the Asian honeybee, Apis cerana cerana, which is less aggressive than African or European honeybees. During the dry season, we had to provide food and water for the bees, and during the rainy season, high winds and storms disturbed the hives. As a result, hive health suffered, and colonies absconded frequently.

Honey production, which was a major incentive for participating families, was minimal. People lost interest in beekeeping or found that the practical challenges of beekeeping with hives suspended from posts, in an environment not particularly amenable to widespread beekeeping, were too great.  

Community motivation, willingness to participate, and capacity

Motivation for using beehive fences fluctuated throughout the trial. Initial excitement wavered when it took time to source colonies or when colonies absconded. When planting or harvesting, people had little time to maintain fences, rendering it a low priority when they were uncertain of fence effectiveness.

Most families felt the beehive fences slowed elephants down. They believed elephants thought the connecting wires were ‘electric’ and paused, giving people time to chase them away using ‘traditional’ techniques such as throwing firecrackers, shouting, and using torch lights. However, they were not able to rely on the beehive fences as the primary line of defence.

The relationship and dynamics between myself and the community was interesting. I often found people told me what they thought I wanted to hear, which was generally that they loved the fences. Yet actions didn’t always reflect this. It was only in my third and fourth years, that some community members felt comfortable to openly discuss challenges or frustrations with their beehive fences. These conversations typically occurred informally, while working on the fences or beekeeping together, or sharing tea or food. During more structured interviews, people reverted back to sharing only positive thoughts. While difficult to analyse in an academic context, the value of knowledge generated through informal conversation cannot be overstated.

Finally, people’s capacity to maintain and continue using their fences once our trial ended was extremely limited. Despite being relatively inexpensive compared to other techniques, no households in the community could afford to replace posts, hive parts, or colonies. After three years, only three participating families were confident in their beekeeping skills. Although we tried to set up local, ongoing support, this unfortunately did not eventuate. When I visited the village early this year (2020), only one beehive fence remained, and community leaders said they had received no assistance since 2018.

Editor’s note: Is that it for the beehive fence approach in Asia? Not quite. Stay tuned next week, for Part 2, a study conducted in Thailand!
