Conservation Evidence: Evidence Data

Collected Evidence: Collected Evidence: Remove and relocate ‘problem’ animals One replicated, before-and-after study in India found that ‘problem’ rhesus monkeys that were translocated, alongside other interventions, survived and remained at the release sites for at least four years. One controlled, before-and-after study in Kenya found that after 16 years, most crop-raiding olive baboons that were translocated from farmland, alongside other interventions, had survived and had similar survival rates compared to non-translocated populations. One before-and-after, site comparison study in the Republic of Congo and Gaboon found that 84% of the ‘problem’ western lowland gorillas that were relocated, alongside other interventions, survived for at least four years.

One study in the Democratic Republic Congo found that chasing gorillas and using random noise resulted in the return of gorillas from plantations to areas close to protected forest.
