Collected Evidence: Collected Evidence: Implement a ‘no-feeding of wild primates’ policy One controlled, before-and-after study in Japan found that several previously increasing Japanese macaque populations declined in size and productivity after limiting and then prohibiting food provisioning.

'No evidence' for an action means we have not yet found any studies that directly and quantitatively tested this action during our systematic journal and report searches. Therefore we have been unable to assess whether or not the action is effective or has any harmful impacts. Please get in touch if you know of such a study for this action.Collected Evidencehttps%3A%2F%2Fconservationevidencejournal.com%2Factions%2F1503https%3A%2F%2Fconservationevidencejournal.com%2Factions%2F1503Tue, 17 Oct 2017 20:01:26 +0100Collected Evidence: Collected Evidence: Restrict the number of people that are allowed access to site We found no evidence for the effects of restricting the number of people that are allowed access to the site on primate populations.

One before-and-after study in the Republic of Congo found that most reintroduced chimpanzees survived over five years after human communities were resettled, from the protected area alongside other interventions.

Three studies, including two before-and-after studies, in the Republic of Congo and The Gambia found that 70% of reintroduced chimpanzees treated for parasites, alongside other interventions, survived for at least 3.5-5 years and in one case the population increased. One study in Gabon found that 33% of reintroduced mandrills died within one year after release despite being treated for parasites, alongside other interventions. Two site comparison studies in Vietnam found that most reintroduced pygmy slow lorises died or disappeared (lost radio signal soon after release) despite being treated for parasites, alongside other interventions. One before-and-after, site comparison study in the Republic of Congo and Gabon and one before-and-after study in Gabon found that most western lowland gorillas treated for parasites, alongside other interventions, survived over nine months or four years.
