Release of rehabilitated Chlorocebus aethiops to Isishlengeni Game Farm in KwaZulu-Natal, South Africa

Abstract

Chlorocebus aethiops are treated as vermin by some in South Africa, and this has resulted in injury, illness and death of hundreds of C. aethiops, with orphans being very common. Rehabilitation centres care for, rehabilitate and aim to return these monkeys to the wild. This study describes the release of 29 C. aethiops to Isishlengeni Game Farm in KwaZulu-Natal, South Africa. The troop was monitored for six months. Confirmed survival of the troop was 62%, with 17% suspected mortality and 21% of the troop unaccounted for. The release site was not ideal due to hunting activities, the proximity of dwellings and roads and the presence of a wild troop. Preparation for release could be improved through the provision of naturally occurring foods and pre-release disease screening. Post-release monitoring would greatly benefit from the use of tracking devices to allow all animals to be followed post-release.
