The aerial cull took place in Australia's largest national park, Kakadu.
Kakadu national park in Australia has seen its animal population flourish as of late. So much so, in fact, that the park just completed an aerial cull of more than 6,000 animals.
Like many of Australia's cull efforts, this one was conducted by sharpshooters in helicopters.
These sharpshooters worked for 24 days. And after just over three weeks the results were intense. In total 3,654 horses, 1,965 buffalo, almost 300 pigs, and a few donkeys were killed.
The population of feral animals in the park was becoming unsustainable. Pete Costell, the park's manager, suggests that the population of free-range wilderness animals in the park has been growing by an incredible 25% per year. "It really got to the point where they started to do some quite significant damage."
This was the first cull for the park since 2009. An additional 6,000 animals were harvested at that time.
