High levels of tourism can lead to a dramatic reduction in the number of cheetahs able to raise their young to independence, new research has found.

A study in Kenya’s Maasai Mara savannah found that in areas with a high density of tourist vehicles, the average number of cubs a mother cheetah raised to independence was just 0.2 cubs per litter – less than a tenth of the 2.3 cubs per litter expected in areas with low tourism.

Dr Femke Broekhuis, a researcher at Oxford University and the author of the study, surveyed cheetahs in the reserve between 2013 and 2017 to assess how the frequency of tourist vehicles affected the number of cheetah cubs that survived to adulthood.

“During the study there was no hard evidence of direct mortality caused by tourists,” such as vehicles accidentally running over cubs, Broekhuis said. “It is therefore possible that tourists have an indirect effect on cub survival by changing a cheetah’s behaviour, increasing a cheetah’s stress levels or by minimising food consumption.”

Broekhuis said she has seen as many as 30 vehicles around a single cheetah at the same time. “The most vehicles that we recorded at a cheetah sighting was 64 vehicles over a two-hour period,” she said.
