There are feral camels in Australia? Why?

Numbers of wild camels in Australia have dropped by a quarter in recent years because of drought and culling, a wildlife survey shows.

The camel population was estimated at one million a few years ago, but the body tasked with controlling the animals says it has fallen to 750,000.

Introduced in the 1800s, the camels now form the world’s biggest wild herd.

But the camels cause significant environmental damage, and in 2010, the government endorsed a control plan.

The Australian Feral Camel Management Project (AFCMP) aims to reduce camel densities through culling and mustering the animals for sale.
