Wildlife tourists on safari are damaging the health of elephants and making them more aggressive towards each other, according to new research.
The study, the first analysis of its kind shows wildlife tourism is making free ranging elephants more anxious because of the large numbers of people.
Hordes of tourists turning up in jeeps and taking pictures is also responsible for herds retreating away from where they are resting or feeding.
Income generated from the industry is potentially vital in the protection of animals and their habitats, but the British-led team say we need to consider its effect.

Wildlife tourists on safari are damaging the health of elephants, stressing them out and making them more violent towards each other, according to new research. Income generated from the industry is potentially vital in the protection of animals and their habitats
Over 15 months, researchers from the university of Liverpool, examined elephants in South Africa.
They found elephants were more likely to be aggressive towards other group members when there were was a large number of people.
Lead author Doctor Isabelle Szott said: ‘Tourists who wish to observe animals in their natural habitat should be aware of their potential negative effects on animal welfare.’
‘Research should investigate best practice standards to minimise such negative effects.’
Increasing numbers of tourists are interested in observing wildlife such as African elephants.
It is known captive elephants trained for riding, or performing funny tricks, often develop post-traumatic stress.
But the analysis shows wildlife tourism is making free ranging elephants more anxious and frightened.
Doctor Szcott said aggression among elephant rose in parallel with tourist pressure, with males more prone than females.
‘We found elephant herds became increasingly likely to move away with increasing numbers of vehicles present.’
Impacts of wildlife tourism on animals are not well understood but a few previous studies have found it fuels more fear, alertness, aggression, vigilance and stress behaviour in a range of animals including rhinos and bison.
‘Mega-fauna, such as African elephants, are among the most popular species for wildlife viewing, particularly for international tourists,’ she said.
‘Yet research assessing the impact of tourist pressure, in form of monthly numbers of tourists, or tourist presence, in form of vehicle presence, on elephant behaviour is scarce.
A 15 month study in South Africa found elephants were more likely to be aggressive towards other group members when there were was a large number of people, reports the Journal of Zoology
‘Elephants in unfenced areas have been reported to avoid human roads and settlements by altering their behaviour and movement suggesting active avoidance of human contact by some herds.’
The findings were based on 26 individually identified male and female elephants observed at Madwike Game Reserve in North West Province between April 2016 and June 2017.
Elephant viewing occurs almost exclusively from game drive vehicles (GDs) where elephants are encountered on roads.
This is a large, open safari truck, with a qualified field guide at the wheel, that seats up to ten people along with a ‘spotter’ at the front of the vehicle.
No more than three GDs were allowed at an elephant sighting, and the researchers’ vehicle was not included in this number.
Dr Szott said: ‘Our results show that even with regulations in place, where wildlife viewing is carried out exclusively from GDs driven by qualified guides and overall numbers of tourists viewing elephants at any time are restricted, tourism led to changes in behaviour of the viewed elephants.’

She said that elephants at waterholes could experience frustration and stress, as well as being the target of other herd members, increasing the possibility they will display aggression towards bystanders in vehicles.
A consistent minimum distance from the nearest individual, especially upon first approach, should be introduced to guidelines for wildlife viewing to alleviate the potential for conflict between tourist vehicles and wildlife, Dr Szott suggested.
‘It would further give elephant herds, or indeed other wildlife, more space and may reduce the likelihood of animals moving off, giving tourists longer, more natural viewing experiences.’
She said that reserves should monitor elephant behaviour to identify when tourist pressure has potential effects on elephant welfare and train guides to monitor behaviour and adjust minimum distances flexibly.
‘This study further contributes to a small but growing body of literature on non-consumptive wildlife tourism impacts on wild animals.’
The findings were reported in the journal Zoology.
DO ELEPHANTS HAVE HUMAN-LIKE PERSONALITIES?
New research has proven that elephants’ emotional characteristics are similar to those of humans.
It turns out the animals have distinct personalities.
They can be aggressive, attentive and outgoing.
For the study scientists asked elephant riders, or mahouts, to answer questions about the behaviors of the animals they worked with each day.
A new study has found that elephants, like humans, have distinct personalities. They can be aggressive, attentive and outgoing. Pictured is an elephant with its mahout, or rider, who the animal works with each day in Myanmar’s timber industry
Dr Martin Steltmann, who worked on the new report, explained how his team defined the traits that categorize elephants.
He said: ‘Attentiveness is related to how an elephant acts in and perceives its environment.
‘Sociability describes how an elephant seeks closeness to other elephants and humans and how popular they are as social partners.
‘Aggressiveness shows how aggressively an elephant acts towards other elephants and how much it interferes in their social interaction.’
Dr Steltmann’s team is hopeful the new research can aid in elephant conservation efforts.
