Human-elephant conflict is on the rise across Africa and is a major threat to wildlife conservation. Crops provide a highly nutritious food source, but elephants pursuing that source results in the destruction of farmer livelihoods, erodes human tolerance toward wildlife and manifests in retaliatory violence on crop-raiding elephants.
Crop conflict was assumed to be mostly carried out by a select few elephants, but managers have lacked the means to assess this at a detailed level. New research, however, offers a first look at long-term trends in crop-raiding behavior. Researchers found that habitual crop-raiding elephants are only a part of the problem.
The study was led by an international team of researchers from Colorado State University, Mara Elephant Project, Grumeti Fund, Tanzania Wildlife Research Institute, Kenya Wildlife Service and Save the Elephants. It was published Nov. 2 in the Journal of Animal Ecology.
Researchers said that the findings could help conservationists better understand elephant behavior and develop new mitigation methods to reduce human-elephant conflict.
The team used the time spent in crops each year to classify the raiding elephants’ behavior as:
Sporadic and seasonal elephants made up two-thirds of the population and accounted for 67% of agricultural use, while habitual individuals made up just 9% of the population and accounted for 32% of crop-raiding. The choice of tactics was not constant over time and elephants frequently changed tactics between years, which showed how the animals must balance the mortality risks and nutritional benefits of crop use at both daily and yearly scales. Only five of nine elephants remained habitual raiders for consecutive years.
Patterns of elephants accessing agriculture as a food source ‘remarkably consistent’
“Elephants are incredibly unique animals and populations and individuals within those populations vary markedly in the extent to which agriculture is utilized,” said Kristen Snyder, a conservation scientist at CSU and the Grumeti Fund, and a co-author of the new study. “But the patterns of how agriculture is accessed — nocturnally, and while moving quickly — is remarkably consistent across individuals and populations.”
Traditionally, researchers and managers believed only a small contingent of elephants was responsible for the majority of crop raiding, and as a result, management strategies have been designed to thwart them, explained Nathan Hahn, a doctoral student in ecology at CSU and lead author of the study.
Hahn said that the team wanted to assess how that expectation aligns with actual elephant behavior.
“It turns out crop-raiding is a lot more prevalent in the study populations than we knew previously,” he said. “In addition, patterns of conflict are complex because we saw that individuals frequently changed their agricultural use between years.”
The research team analyzed nine years of GPS tracking data from 66 collared elephants —32 male and 34 female — in collaboration with Kenya Wildlife Service and the Tanzania Wildlife Research Institute in the Serengeti-Mara Ecosystem. This ecosystem is a vast network of wildlife reserves, parks and community conservancies that straddles the Kenya-Tanzania border.
The GPS data was used to determine the extent to which each individual elephant used agriculture and assessed the animals’ perception of risk based on the raiding tactics they employed in comparison to their daily movement patterns.
A ‘silver bullet’ approach is elusive for a complex species
Jake Wall, director of research and conservation for Mara Elephant Project and affiliate faculty at CSU, said that by using GPS tracking coupled with remote-sensing agricultural spatial information, scientists now have a method for characterizing crop-raiding behaviour within a given elephant population.
“This in turn should help improve elephant crop-raiding mitigation strategies by wildlife managers,” he said.
Snyder said that the study’s findings can identify crop-raiding mitigation strategies that could have an impact and, just as importantly, eliminate those that do not suit the local context.
“In the western Serengeti, the high prevalence of agricultural use among the study population indicates that strategies targeting individual problem animals are unlikely to significantly reduce crop damage,” she explained.
Individual or small-scale approaches will make little difference if 80% of the local elephant population regularly utilize agriculture as a food source.
“Instead, solutions that prevent elephant access to farms across broad scales are required,” said Snyder.
CSU Professor George Wittemyer said that elephants employ complex, adaptive movement that balances their desire to access resources while avoiding threats. He is a senior author of this study and also serves as chairman of the scientific board for Save the Elephants.
“This research shows how that perceived balance differs between individuals, but also shifts over time for a given individual,” Wittemyer said. “This variation underpins the difficulty in solution oriented human-elephant coexistence measures. As we often find, a silver bullet is elusive for a species as complex and clever as elephants. We must be as adaptive as they are when trying to solve these problems.”

PUBLIC CONSULTATION – The Canadian federal government has launched a public consultation to hear feedback on proposed measures to restrict or end the elephant ivory trade!
Everyone is urged to participate in the consultation to provide government feedback. Please take action by sending in pre-written letter here.
VANCOUVER (July 23rd, 2021) – Elephanatics and the Ivory-Free Canada Coalition (Humane Society International, Jane Goodall Institute of Canada, Elephant and Rhino Defenders, World Elephant Day) are pleased to hear that the Canadian federal government has launched a public consultation to hear feedback on proposed measures to restrict or end elephant ivory trade.
The Ivory-Free Canada coalition along with William Shatner, Bryan Adams, Robert Bateman, and other notable Canadians are calling for a ban on the elephant ivory trade in Canada.
In the past century, the African elephant population, which is currently listed as critically endangered/endangered by the International Union for the Conservation of Nature, has declined by 96%, with leading scientists warning the population could be lost altogether within the next few decades in the absence of global intervention to disincentivize poachers.
A Canadian petition launched by the coalition has garnered 636,180 signatures asking the Canadian government to end the legal trade of elephant ivory in Canada.
Every year, as many as 35,000 elephants die at the hands of elephant ivory poachers in Africa. The African elephant population has declined by a staggering 96 percent in the last century, and African elephants are at risk of becoming extinct within a couple of decades. In March of 2021, the International Union for Conservation of Nature (IUCN) updated the IUCN Red List of Threatened Species and declared the African forest elephant to be Critically Endangered and the African savanna elephant to be Endangered. Africa’s biodiversity is already threatened, and further loss of elephant populations will have devastating consequences.
The decline of African elephants is largely driven by poaching, motivated by demand for ivory. Accordingly, a Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) resolution calls on the world community to shut down legal domestic ivory markets “as a matter of urgency”. This resolution mirrors the position of The African Elephant Coalition, which represents 78 percent of African elephant range States, as well as the position of an IUCN resolution on the closure of domestic ivory markets. Canada’s top trading partners, including the United States, China, and the United Kingdom have taken action in response.
Fran Duthie, President and Founder of Elephanatics, stated: “Tens of thousands of African elephants are killed every year to fill the global demand for elephant ivory. The world community is taking action, and more than 630,000 people have signed a petition calling on the Canadian government to ban elephant ivory trade as a matter of urgency. We encourage all Canadians to take part in the consultation and make their voices heard for African elephants.”
Robert Bateman, renowned Canadian artist and conservationist, stated: “The survival of African elephants hinges on the actions of the global community, and progressive nations like Canada have a responsibility to act accordingly. I am joining countless Canadians in calling on the Canadian government to act now and ban elephant ivory trade. I commend the government for launching a public consultation and encourage all concerned Canadians to take this critically important opportunity to speak up.”
Michael Bernard, deputy director of Humane Society International/Canada, stated: “Canada is at a crossroads and the actions we take now to protect African elephants will be remembered for generations to come. In keeping with its commitments to preserve global biodiversity and end human-induced extinctions, the Canadian government has launched a crucial public consultation. We urge all Canadians to participate and make clear that only a robust national ban on elephant ivory trade can truly help us end the senseless killing of African elephants.”
