Found out Department of Environmental Affairs has simply told SANParks there will be no culling of elephant in Kruger, end of story.

Elephant contraception is not an answer in reserves that has a carrying capacity of more than a few elephant. The reason why is as follows.
Elephants has a social structure consisting of a Female group, the breeding herd. Young males leave the group to roam alone or in the company of Bulls. When a female of the herd comes into oestrus surrounding males will converge, fight for mating rights, thus throwing the herd into a cycle of serious stress. If we take a herd of 10 breeding cows, this will happen not more 10 times in 3 years, taking into consideration a period of 22 months for pregnancy, and on average 14 months for weaning of calf before a female comes into oestrus again.
In the effect of contraception it will happen 10 times every 4 weeks, thus increasing stress levels of the herds to above the accepted limits and standards for a establishment where tourists will reside and come into contact with these animals.
As example, a small reserve like Mabula, this can work as there is only 1 breeding bull regular in contact with the herd, thus not too much stressfull interference. But in Kruger, or any of the other parks with normal interaction it will create a dangerous environment. This was tried in Kruger in 20 years ago with dire consequence in the crocodile bridge area in Kruger. Aggressive elephant behaviour more than normal. Tourists getting vehicles charged and trashed, etc.

Ja, I still think it may work if they can figure out a way to contracept cows via darts from helicopters.
It is simply too expensive and stressful to drug them first and what not?
Best would be to be able to sterilise bulls from the air?
Their family problems are a small price to pay vs culling, IMO?

Does not help towards a solution
Unfortunately I am afraid that poaching will resolve the problem sooner or later

At least 8000 need to be removed, Lis, depending on the results of a proper census...
Poachers won't be able to do that.
Dr Whyte is very respected and experienced, but ja, no solution...in the meantime we wait.
He is dead right about the threat to river vegetation, which is already happening seriously.
