Sanparks gave their opinion 12 years ago 
A lot of things must have changed since then. At the moment, what are they doing? culling? The vaccine has been improved since year 2000 and probably the price is lower too if used on a large scale.
I must run and have a look at the "Culling" thread.......

I thought I had seen a "Culling" thread, but cannot find it. Can someone perhaps help?

SA planning elephant birth control

Durban - KwaZulu-Natal, home to thousands of elephants, is planning a birth control campaign for the pachyderms to prevent a population explosion that could threaten plants and wildlife.
Unlike other parts of Africa where elephant stocks have dwindled to dangerously low levels due to poaching and a loss of habitat, SA has seen its populations steadily grow through conservation, with the country pressed for room to house the massive animals with hefty diets.
KwaZulu-Natal is looking to expand a project running for more than a decade where elephant populations have been controlled by injecting cows with a vaccine that triggers an immune system response to block sperm reception.
"Slowing the growth rate will allow time to be gained to achieve other biodiversity objectives, such as land expansion, without having to cull the elephants," said Catherine Hanekom, an ecologist for Ezemvelo KZN Wildlife.
SA, which had just over 100 elephants nearly a century ago, now has more than 20 000, studies said.
Reversible
The overpopulation problem is most dire in neighbouring Botswana, home to at least 133 000 elephants, where vast forests have been lost to satiate their appetites. With a human population of two million, it has the highest elephant-to-people ratio in Africa, at one for every 14 people.
Adult elephants consume about 100kg to 300kg of food a day and most elephants in SA are in fenced-in reserves where vegetation could be decimated if populations grow too large.
"Because we have taken away opportunities, they don't have the chance to remedy the overpopulation naturally as they would through migration," said Audrey Delsink Kettles, an elephant ecologist who has been leading studies for years on contraception at Makalali Private Game Reserve.
Testing of the vaccine, administered by dart and requiring an annual booster, has been conducted at 14 small reserves. Studies have shown it is reversible, nearly 100% effective and has no adverse impact on elephant health or behaviour, Kettles said.
Contraception is seen as a humane alternative for controlling populations over the other main options of culling herds or moving them vast distances to areas with more food.
The Humane Society of the US and Humane Society International have backed the vaccine.
"Failure to control the reproduction of the species... leads to a population that exceeds the carrying capacity of the reserve and to habitat degradation," they said in statement.

According to Kruger, who don't really know how many elephant they have, this is not the case...
What is the price of the "vaccine", I wonder, and the price per administered dosage re. using helicopters and staff, I wonder?

That goes for animal and human numbers.

If the cost of catching a Rhino and treating their horn is around R 15000.00 per animal, I pressume it will be the same for an elephant. Multiply that by roughly 6000 and you have quite a hefty sum.
i do not think the coffers of Sanarks are deep enough an I do not see the good dictator, sorry doctor, spending one Rand of his "hard" earned money to take care of that.

Hey!
If it works and is affordable, great!
But the "ten year" thing tells me it is not new.
If I remember correctly the old "vaccine" does not keep the cows out of oestrus, which causes chaos in the social relationship and constant bull competition and endless mating.
Also, I don't know how much experience the American and International Humane Societies have with African paradigms?
Elephant are not stupid, to put it mildly!

Years ago the conclusion was that it was not feasable.
Maybe now it is, but it will cost a helluvah lot of Dineros and I doubt Sanparks are going to pay that.
Furthermore.
You are right.
those animales are not stjoepid at all
