Measuring success in primate translocation: a baboon case study

Area of Science:

• Primate Ecology and Conservation
• Wildlife Translocation Studies
• Behavioral Ecology

Background:

• Translocation of primates is infrequently documented, making success evaluation challenging.
• Long-term data is crucial for assessing the viability of translocated animal populations.
• Wild baboon research prior to 1984 provided a baseline for evaluating post-translocation outcomes.

Purpose of the Study:

• To comprehensively evaluate the success of a 1984 wild baboon translocation event.
• To establish robust criteria for assessing primate translocation success using multiple biological indicators.
• To compare the performance of translocated baboons with indigenous populations and other translocated primate species.

Main Methods:

• Utilized 12 years of pre-translocation and 18 years of post-translocation data for two wild baboon troops.
• Established two key success criteria based on indicator measures: birth rate, death rate, mortality/survivorship patterns, body condition, parasite load, and group size.
• Employed indigenous baboon troops at the release site as an independent control group for performance comparison.

Main Results:

• The translocated baboon troops met both established success criteria, indicating the translocation effectively saved the populations.
• Post-translocation baboon performance, measured by various biological indicators, was comparable to or better than indigenous troops.
• The success of this baboon translocation surpassed that observed in other translocated primate species.

Conclusions:

• The 1984 translocation of wild baboons was a demonstrable success, ensuring the survival of the studied troops.
• The established criteria provide a reliable framework for evaluating the long-term success of primate translocations.
• This study highlights the potential effectiveness of well-planned translocations for primate conservation.
