Maintaining strict limits on the use of bromadiolone is good news for wildlife

The Australian Pesticides and Veterinarian Medicines Authority’s (APVMA) has rejected a dangerous proposal to use bromadiolone around the perimeter of crops to control the state’s mouse plague. 

“The APVMA’s decision is a sensible result,” Nature Conservation Council Chief Executive Chris Gambian said. 

“Everybody said when this dangerous proposal was floated that bromadiolone was completely unsuitable for broadscale application. 

“Thank goodness sense and the public interest has prevailed at the APVMA. 

“The governments bizarre attempt to intervene into this mouse plague at the last moment was deeply flawed and ill considered.  

“This has been an unwelcome distraction from real task of finding safe solutions to this terrible problem.  

“We all sympathise with communities battling this plague, communities that have only recently emerged from years of drought.  

“But the last thing anybody wants is to make a bad situation worse by using chemicals that would poison wildlife food chains and potentially kill farm animals like working dogs and house cats.”  


Feral horse numbers in Kosciuszko could fall 95% under new proposal

The infestation of feral horses destroying rare ecosystems and killing threatened species in Kosciuszko National Park could be reduced by 95% if targets agreed by Nationals Leader John Barilaro today are met.

Mr Barilaro reportedly now supports reducing the feral horse population in the park from an estimated 14,000 to between 3,000 and 600, a reduction of between 78% and 95%. [1] 

“We stand ready to work with Mr Barilaro and Environment Minister Matt Kean to tackle the infestation of feral horses that is destroying fragile alpine ecosystems,” Nature Conservation Council Acting Chief Executive Jacqui Mumford said.

“We must always aim for the eradication of destructive feral pests, especially in our national parks, but total removal is possibly unrealistic. 

“Under the circumstances, a target of between 600 and 3,000 is a good range.

“There are many challenges that conservation managers and scientists face in hitting that target, not least of which is the 2018 Kosciuszko Wild Horse Heritage Act that gives wild horses special protected status.

“That law is a significant impediment to practical, science-based management of our alpine parks. 

“We encourage the government to urgently repeal the act so conservation managers can protect threatened species like the corroboree frog and their fragile mountain streams, which are being trashed by thousands of hard horse hooves every day.”

Doubling of feral-free zones throws a lifeline to threatened species

Today’s pledge to more than double feral-proof reserves in NSW to 45,000ha is a fine way to cap a year of very positive environmental pledges by NSW Environment Minister Matt Kean. 

It comes on top of commitments to add 400,000 hectares to the national parks system, double the number of koalas by 2050, and massively expand the renewable energy sector. 

“These bold measures have rightly been applauded by the general community,” Nature Conservation Council Chief Executive Chris Gambian said. 

Mr Kean’s announcement today acknowledges the sad fact that feral-proof enclosures are the only hope for some of our most vulnerable species. 

“Until we have effective ways of controlling foxes and cats, these types of reserves will be a vital conservation strategy.” 

Feral-proof enclosures have enabled the reintroduction to western NSW of several species that had become extinct in this state, including bilbies and numbats.  

Mr Kean will reportedly announce funding today [1] to expand the feral-roof reserve system in NSW from 20,000ha to 45,000ha, including:  

  • 40,000ha at Yathong Nature Reserve near Cobar Yathong Nature Reserve near Cobar  
  • 3,000 ha Ngambaa Nature Reserve near Macksville 
  • 1500-2000 hectare enclosure in the Eden Bombala region  
  •  500ha within the Castlereagh Nature Reserve in Sydney’s north-west 

These add to sites in the Pilliga State Conservation Area and Sturt and Mallee Cliffs National Parks in the far west. 

“While feral predators are a very serious threat to some of our most vulnerable species, habitat destruction is still the leading cause of species extinction,” Mr Gambian said.  

“The leadership role being played by the National Parks and Wildlife Service is very welcome 

The next opportunity is to work with private land holders to improve conservation outcomes on farms and other private land. . 

“The majority of ecosystems and threatened populations are on private land and in state forests. 

“Species will continue to decline until government policies that encourage massive habitat destruction through excessive land clearing and logging are overturned in favour of a more balanced approach.”
