The Guardian is reporting that 90% of the Snowy Mountains brumbies would be culled over the next two decades, under a plan released by the New South Wales government.

The draft wild horse management plan for Kosciuszko national park aims to cut the population of wild horses in the park from 6,000 to about 3,000 in the next five to 10 years.

The population would be dramatically slashed to just 600 within 20 years, confining the wild horses to three locations inside the national park.

Current numbers of wild horses were unsustainable and the animals were damaging the park’s fragile alpine and subalpine landscapes, the NSW environment minister, Mark Speakman, said.
