New Census Shows Startling Decline in African Elephants
The great elephant census is out. It`s a massive project looking at the population of the world`s largest mammal across the African continent.
It found that a large percentage of African savannah elephants is gone. The reason: mostly poaching when people illegally kill animals.
Why? The tusks of elephants are ivory. The material is illegal to sell in many countries, but small amounts of it are worth thousands on the black market. So, the slaughter of elephants is hard to stop.
From Botswana, CNN`s David McKenzie took flight with the researchers.
DAVID MCKENZIE, CNN INTERNATIONAL CORRESPONDENT (voice-over):
Getting ready to fly in Botswana`s far north. Elephant ecologist Mike Chase has spent years counting savannah elephants from the sky.
MIKE CHASE, ELEPHANT ECOLOGIST:
Never before have we ever conducted a standardized survey for African elephants at a continental scale.
All right. Start counting, nice speed, nice height, well done, Tammy.
Hundreds of air crew counted elephants in 18 countries across the continent over two years.
Elephant seventh, seven elephants.
Flying the distance to the moon and then some. There were results more shocking than anyone imagined.
We spent thousands of hours of counting, flying over areas where elephants historically occurred, but no longer present in this habitat.
Killed for their ivory in seven short years up to 2014, elephant numbers dropped by a staggering amount, almost one-third. Across Africa, their numbers are crushing. If nothing changes, the elephant population will halve in less than a decade. In some areas, they will go extinct.
In some landscapes, we saw more dead elephants than live elephants.
I don`t think anybody in the world has seen the number of dead elephants that are seen over the last two years, the great elephant census. For me, this becomes a lot more personal.
We continue to check 22.
To fight the war, Botswana has mobilized the army. With more than 700 troops guarding its northern border. Patrol spent days in the bush on foot, armed with a shoot to kill policy for poaches. They`re up against a sophisticated enemy.
They`re looking for any sign of poachers. If they come across them, they`re often highly organized groups of about 12 people. Two of them could be shooters often, and those shooters are frequently foreign special forces.
Mike Chase`s research proves that if we can`t protect elephants, they will learn to protect themselves.
You can hear him snoring. Is that a he or she?
He. He`s in his prime, about 30 to 35 years of age, and it`s these young bulls that have propensity to move dramatic distances and met their trans-boundary conservation corridors.
But their satellite tracking shows that the elephants used incredible levels of intelligence to avoid poaching hot spots in neighboring countries, retreating to the relative safety with Botswana.
It`s quite incredible being this close to this animal.
It is. It certainly is.
We call this bull "Promise", for the promise that Mike Chase has made and perhaps we all should to save this magnificent species.
