The habituation of mountain gorillas to human presence enables conservation-funding tourism but involves welfare costs during the process and ongoing welfare considerations.
Mountain gorilla habituation welfare involves an explicit welfare-conservation trade-off that conservation practitioners and ethicists have analyzed extensively. The habituation process causes chronic stress in individual gorillas over approximately two years — this is a welfare cost that cannot be denied. The benefit is conservation funding that has enabled a population recovery from near-extinction, veterinary intervention capacity that has saved individual lives from snares and disease, and anti-poaching protection that reduces the highest direct welfare threat to gorilla groups. The weight of evidence suggests that habituated gorilla groups have better survival rates and population outcomes than unhabituated groups — meaning the welfare cost of habituation is offset by welfare benefits of the protection it enables. This does not remove the ethical obligation to minimize habituation stress and ongoing welfare impacts through careful protocol design.
