Chacma baboons (Papio ursinus) form a part of the Cape Peninsula’s rich biodiversity. The Cape Peninsula baboons are considered to be a major tourism asset and play a potentially significant ecological role in the Cape Floristic Region.

Under the current scientific management programme, the Cape Peninsula baboon population is growing steadily (4% per year).

The population is not endangered, nor is it under threat.

The welfare of baboons rises when the conflict between baboons and urban dwellers is scientifically managed. 

In the long-term, the management goal is to reduce conflict between humans and baboons. To this end, 63 baboon rangers, funded by the City of Cape Town, work to keep baboons out of the suburban areas all year round.

Update: Baboon population - June 2019

In the June 2019 census, it was estimated that a total of 449 baboons were living in 11 managed troops on the Peninsula.

There are a further five troops which live in protected areas (National Parks) in the southern Cape Peninsula. The population of these troops is not included in this population data.

Update: Baboon population - June 2018

In the June 2018 census, it was estimated that a total of 414 baboons were living in 11 managed troops on the Peninsula.

There are a further five troops which live in protected areas (National Parks) in the southern Cape Peninsula. The population of these troops is not included in this population data.

**The Misty Cliffs individuals were included in the GOB Troop totals since January 2017, when they merged with the GOB Troop. Some individuals later returned and continue to move above and between Scarborough and Misty Cliffs. Sub-totals are shown to differentiate between the GOB Main Troop and the six individuals (three adults and 3 juveniles).

**The Constantia Troops totals are split between CT1 and CT2 from December 2017 to differentiate between the total baboons for each of these two troops from 2018. 

Update: Baboon population - January 2015

By mid-2014 it was estimated that a total of 550 baboons were living in 16 troops on the Peninsula.

Human Wildlife Solutions (HWS) is responsible for the 10 managed troops.

HWS used the December 2012 census population total as a baseline and accurately recorded birth, deaths and emigrations and immigrations to derive troop numbers among the managed baboon troops.

The latest ground count of the managed population by Esmé Beamish (Baboon Research Unit, University of Cape Town) is accurate up to the end of January 2015.

HWS will now use these counts as a baseline for future counts. They were incorporated into HWS data as of the HWS February 2015 Report.

According to these statistics 383 individuals baboons live in the 10 managed troops on the Peninsula.

The population of the Cape Peninsula managed baboon troops continues to show positive growth.

This is supported by the ratio of juveniles: adult females in the population being greater than 1.

Another positive trend is that overall mortality is lower than the previous year.

The adult baboon sex ratio (number adult males: adult females) is within the normal range for Chacma baboons (Papio ursinus) indicating a healthy male population.

Reduction in 'human-induced mortalities'

Since the implementation of scientific wildlife management, conflict between humans and baboons on the Cape Peninsula has reduced substantially.

Human-induced mortalities (e.g. baboon deaths from pellet guns, car accidents, poisoning or baboon-dog altercations) have reduced from:

  •  63% of all deaths between 2006 and 2008 to
  •  52% of all deaths between 2009 and 2011 to
  •  25% of all deaths between 2012 and 2014

In the long-term, the management goal is to reduce conflict between humans and baboons.

To this end, 63 baboon rangers, funded by the City of Cape Town, work to keep baboons out of the suburban areas all year round.

Update: Baboon population - 2013

In early January 2013, a population census concluded by Esmé Beamish of the Baboon Research Unit (BRU) of the University of Cape Town indicated that the total baboon population on the Cape Peninsula was 501.

The census covered all 16 troops in the Southern Peninsula, including the three splinter troops – Da Gama, Misty Cliffs and Zwaanswyk.
