NSW says it will cut feral horse numbers after survey shows runaway growth

NSW says it will reduce the number of feral horses in Kosciuszko National Park after a new survey revealed an explosion in numbers that is alarming environmentalists and the ACT Government, concerned at the threat to habitat and the water catchment.

The 2019 Australian Alps feral horse aerial survey shows that feral horses have more than doubled in numbers over the past five years from 9180 to 25,318, an increase of 23 per cent a year.

Last year NSW stopped culling the horses after passing legislation recognising their cultural and heritage value, with local National Member for Monaro and Deputy Premier John Barilaro vocal in his support for the ‘brumby’.

While the ACT Government’s review of its feral horse management plan found it had effectively prevented the re-establishment of populations in Namadgi National Park, there are concerns about the ”sustained and increased threat” from horses in the northern end of Kosciuszko National Park bordering the Territory.

NSW Environment Minister Matt Kean offered some solace to the ACT, saying the NSW Government would take steps to reduce the number of horses in the Kosciuszko National Park ”in a humane way”.

He did not say what sort of program this might entail but the current legislation rules out lethal culling, which points to removal from the park or transfer within it.

Mr Kean said the survey estimated that there were about 19,000 horses in the Kosciuszko National Park, compared to about 6,000 in 2014. “These numbers are unacceptable and unsustainable for our natural environment,” he said.

ACT Environment Minister Mick Gentleman said feral horses did not recognise state boundaries and the scientific evidence was clear that heavy-hoofed pests such as feral horses were damaging the landscape.

“I recently toured impacted areas to survey the damage and eroded waterways these heavy-hoofed feral animals cause,” he said.

“I have raised and will continue to press this issue with my State and Federal Government colleagues. We need to conserve our water quality and protect critically endangered animals like the northern corroboree frog, which lives in the moist alpine bogs of the ACT high country.”

Mr Gentleman said the integrity of the high-country areas was vital to preserve the quality of Canberra’s drinking water, and the water that flows from the Australian Alps, which contributes more than 30 per cent of inflows into the Murray-Darling system.

Feral horses that do cross into Namadgi are trapped, shot and removed but Mr Gentleman fears that if numbers keep growing the pressure on the ACT may eventually necessitate aerial culling.

National Parks Association of the ACT (NPA ACT) president Esther Gallant said feral horse numbers in the NSW and Victorian sections of the Australian Alps had multiplied unchecked to the point of destruction of crucial headwaters wetlands of the Murrumbidgee, Murray and Snowy rivers.

Two recent NPA ACT field trips into the region of Kosciuszko National Park west of the Brindabella Mountains and adjacent to Namadgi had confirmed the severity of the damage being caused by feral horses.

“The horses are trampling sensitive ecosystems, causing massive damage to native vegetation in many areas, especially to sphagnum moss, which plays an important role in maintaining water supply during dry periods by gradually releasing stored water,” she said.

Professor Gallant said the increasing numbers threatened to make implementation of ACT Government policy more difficult and costly for Canberrans.

“Deer and pigs are already damaging Namadgi National Park, although efforts to reduce the number of these ungulates – hard-hoofed animals — are underway. If we have another bushfire in Namadgi of the magnitude of the 2003 fires, there would be no possibility of recovery with large ungulates immediately devouring every bit of green regrowth.”

The review will contribute to an updated ACT feral horse management plan in 2020 that will incorporate the latest science and population numbers.

The current ACT plan is available from the Environment, Planning and Sustainable Development Directorate.

why dont you ever comment on the pigs or deer that do just as much if not more damage. I am really sick and tired of the brumbies getting the blame constantly for other feral animals that do more damage!!!! ok keep the brumbies managed but start with the pigs and deer!!! I am so over the bashing of brumbies
and I doubt very much that there are 23,000 horses in the park!!! they have probably been counted twice and considering mares ONLY have 1 foal per year and probably 40% die while having foals anyway……….

First of all I am in agreement with sustainable management of brumbies through passive capture, rehoming and fertility control. However if in 2914 there were 6000 horses and in 2019 there were 25,000 horses horsed that means there were no horse deaths in that time? does that mean even geriatric mares had foals? Does that mean each pregnancy was a live foal? Does that mean there was no predation or injuries to horses so they could not procreate? If that’s the case then 6,000 horses of which half would be female still would not equal that extraordinary number – please can someone challenge even the maths of this preposterous claim –

The impossibility of this COUNTis really worrying!!
The fact that the ACTUAL COUNT was mathematically manipulated and flawed in many ways seems to HAVE gone unchallenged by journalists!! Physically impossible for these numbers and if journalists actually did their jobs and investigated this claim they’d soon discover basic flaws and not be publishing government propaganda to cull them on manipulated data to suit their agenda

    PLEASE will you leave ecology topics like population growth rates, to professional ecologists, likewise wildlife counting. As the report explains, there is nothing implausible about the numbers. I accept that non ecologist, non mathematicians struggle to accept them because the comments show they do so. But please be honest enough to admit, you dont have the qualifications and experience.
