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.

Trialing Camera Traps 

We’re partnering with Bring The Elephant Home in Thailand to trial the potential of alternative crops to support farmers living with elephants. We’re excited to bring the first news from the field, by Brooke Friswold, who is a PhD student at King Mongkut University of Technology Thonburi!


by Brooke Friswold

The team in Thailand has been busy over the last two months – especially while director and founder of Bring the Elephant Home (BTEH) Antoinette van de Water has been in country! With the start of data collection for a subset of five BTEH rented lemongrass plots and ten community-owned pineapple plots on the horizon, equipment and methodology trialing has begun. Data collection via camera trapping is set to begin in mid-May to record baseline elephant behavior in control and experimental plots for the HECTAARE project and for Brooke Friswold’s PhD research with King Mongkut’s University of Technology Thonburi (KMUTT) in partnership with BTEH and HECTAARE.

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.

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

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.

The Consequences of Irresponsible Tourism

By Salik Ansar & SdS

Tourist feeding elephants.

September 27th is World Tourism Day, so today we offer some more reflections based on the Udawalawe experience.


Until the recent COVID-19 epidemic halted travel around the globe, the island of Sri Lanka thrived on tourism. A big part of the country’s GDP is attributed to tourism. According to Sri Lanka Tourism Development Association, 783,000 tourists visited Sri Lanka’s national parks in 2018, which is roughly 38% of the travelers who entered the country. The parks earned over 2 billion rupees (over $11 million USD) in entrance fees alone. Clearly, elephants have a huge economic value (more about this here).

Social Media & Wildlife Tourism: Powerful Tools for Good and Bad

Earlier this month, we launched the Ethical Elephant Experiences campaign to shine a light on the issues that irresponsible wildlife tourism can present and to encourage travelers and travel companies to commit to responsible practices.

Before COVID-19 halted travel, wildlife tourism was becoming increasingly popular, and elephant experiences were at the top of many people’s bucket lists. Wildlife attractions account for 20-40 percent of all tourism worldwide, with up to 6 million people visiting these sites each year. In Asia, there are over 3,800 elephants living in captivity. This is a significant number when you take into account that there are only 40,000-50,000 Asian elephants left in the wild.
