Africa Wild

The Kgalagadi Lion Project

Husband and wife team, Maya and Otto Beukes, are spearheading a groundbreaking project that will reveal critical information on the activities of the lion population in the Kgalagadi Transfrontier Park.

This Kgalagadi Lion Project forms part of the duo’s Masters research in the field of Nature Conservation and is a collaboration between CPUT and the South African National Parks (SANParks).

The project was initiated after a survey conducted in the park, which straddles the border between South Africa and Botswana, found a skewed sex ratio in favour of lion males which could result in a collapse of the park’s lion population.

Maya and Otto will be responsible for conducting a detailed study on the lion population by collecting critical information on their demography and dietary patterns.

“This information will be used to help identify the cause of the sex skew and to inform management decisions on lion conservation in the Kgalagadi Transfrontier Park,” says Maya.

The couple has been working in the park since last year and has already collected a significant amount of data and have identified 141 individual lions.

“In October 2013 four adult female lions were fitted with GPS/VHF collars by SANParks Veterinary Wildlife and Scientific Services. We will use the collars to locate prides as well as prey remains. The collars will also be used to assist with continuous following of collared individuals and their associated prides through telemetric tracking,” says Maya.

The project will run over a two year period and is being supervised by CPUT’s Dr Frans Radloff and SANParks's Dr Sam Ferreira.

Another cat project

Thanks for posting, Toko.

Send in your handsomes and see if you get a name

it seems a nice project, thank you Toko

names already so much names to remember

will follow... in a first time

Firstly, I'm kinda annoyed that this wasn't in my inbox although I asked them to take me on the list and they confirmed.
Secondly, I'm rather disappointed not to get more info on IDed lions.

But thanks for posting, Toks.

Ja, they do not share anything from their database with the visitors

But I like the frog bit

Kalahari lions: Research sheds light on population


© Derek Keats/

Lions are threatened across their natural range, and the Kgalagadi Transfrontier Park (KTP) straddling South Africa and Botswana is a stronghold for the species.

A research project, conducted during 2013-2015 and published in April 2017, resulted in a population estimate of 246 (237–256) lions (most precise of three count methods) in the southwestern sector of KTP, which is higher than previous estimates.

Summary

A 30% population decline and 80% range reduction over the past 20 years has resulted in there being fewer than 20,000 wild lions remaining in Africa, across 65 natural populations. Ten of these natural populations are considered strongholds – and KTP is one of these ten strongholds.

Small populations of animals that are subjected to high rates of human persecution, such as Africa’s lions, have a greater likelihood of extinction, and so understanding trends in population size, age and sex is important.

Previous research over the preceding 40 years suggested a relatively stable Kalahari lion population of 517 lions in the entire KTP, but research in 2010 off a small sample suggested a male bias of 56%, compared to previous research reflecting a female bias of 58%.

The aim of this research, therefore, was to reduce uncertainty as to population size and key variables.

The research was conducted in the dune savanna semi-desert of the southwestern sector of KTP. The area of 14,250 km² covered the Kalahari Gemsbok National Park in South Africa and a buffer strip to the east, in the Gemsbok National Park in Botswana. The researchers drove 49,784 km over 26 months, with 317 days of sampling. They counted 261 individual lions, from 1,162 sightings (of which 1,022 could be identified), and recorded 11 deaths. Of the identified lions, 74 were cubs born during the survey period.

Three methods of counting were utilised, producing the following results:

1. Mark-recapture: 246 (237-256) lions

2. Track indices: 242 (176-307) lions

3. Registration study (after removing known deaths): 250 lions

The report includes a detailed discussion about each of the three methods, including shortcomings and inaccuracies.
