 A biodiversity-crisis hierarchy to evaluate and refine conservation indicators

Nature Ecology & Evolution

New paper using a biodiversity-crisis hierarchy to evaluate Convention on Biological Diversity Aichi indicators.  There are major gaps.  Your challenge now is to find where your daily life intersects with components of the hierarchy and take action to make a change. See the video for some suggestions.

The Victorian government released the “Protection of the Alpine National Park – Feral Horse Strategic Action Plan 2018–2020 (Draft)” on the Friday before the summer break, in the hope that no-one notices.   Comments on the draft plan are due before February 2nd.

Australia’s native plants and animals are integral to the success of our society. We depend on wildlife to pollinate many of our crops. Most of our cities depend on effective water catchments to provide clean water. And medical scientists are making important breakthroughs in managing disease and health issues based on discoveries in nature. Our nature inspires us in all kinds of ways, and you can build major industries around that; the Great Barrier Reef is reportedly worth A$56 billion to the Australian economy.

It is therefore surprising to read the Australian Conservation Foundation and WWF Australia budget submission that the Australian government has slashed environmental spending by one third since 2013.

Read why this is a problem here.

There are two really easy things everyone can do to help reverse the declining trends in environmental funding. The first thing is to talk about it.  Calling all journalists, bloggers, and social media users (I think that’s everyone); report levels of environmental funding compared with what is needed to do the job.  Report and share both track-record of environmental funding and promised budgets as we approach each election.  The second thing to do is vote.  You don’t have to lie in the path of a coal-train or chain yourself to a tree as the bulldozers and chainsaws move in.  All you need to do is vote for the party that will provide the greatest support for the environment.  A massive vote for the environment will send a message to all politicians that the environment must be looked after; our livelihoods and well-being depend on it. And you can go back to voting for whatever party aligns with your principal ideology at the next election; vote for the environment once to fix the funding shortfall.

The threat posed by horses to Australia’s high country species and ecosystems grows, while the Victorian and NSW Governments decide on how to manage the problem.  The massive environmental impacts of feral horses in the alps were graphically illustrated in the submission to the Independent Technical Reference Group by Friends of Currango Inc.  They have first-hand experience of managing land in the north of Kosciuszko National Park since the 1970s, and provide an account of the changes they have observed.

The before-after photographs drive home the statistics in the review of the 2008 Kosciuszko horse management plan which reported that 76% of stream banks were degraded in areas with horses but only 11% were degraded in areas without horses.  This unambiguous damage is why the Ecological Society of Australia has called on the Premiere of NSW to rapidly reduce the number of horses throughout Kosciuszko, using aerial culling, which is the only feasible method given the size of the horse population, and is the method with the fewest welfare concerns.





The Australian Government’s threatened species prospectus was released in March, as a plan to attract investment from industry and philanthropists.  It’s a fantastic communications exercise, maybe even an essential one, but why isn’t the government funding these programs directly? And why aren’t any invertebrates in the prospectus.  We address these issues in this exciting first article from the Ecological Society of Australia comms team.




Australian Ecologists’ Letter to the NSW Premier in support of feral horse control

Public comments on the Kosciuszko National Park draft Wild Horse Management Plan, 2016 closed on the 19 August.

As reported in The Guardian, 41 ecologists, including eminent alpine ecologists and those with expertise in making cost-effective land management decisions sent a letter to the NSW Premier Mike Baird.   In the letter we expressed support for the Kosciuszko National Park Draft Wild Horse Management Plan 2016.  We strongly support a rapid reduction in horse numbers.  We also point out that aerial culling is the most humane and effective method for reducing horse numbers.  We argue that horse numbers need to be rapidly reduced to very low numbers in a shorter time frame than is currently proposed to protect fragile alpine ecosystems and species.

Review the latest news from the Ecological Society of Australia meeting on twitter #ESA15 and #ESA16

I started in my new position at Deakin University, Melbourne Burwood Campus, in the last week of August 2015.

Our paper, recently published in Proceedings of the National Academy of Sciences USA,  flags a major opportunity to avoid future damage to the natural environment. The paper highlights the ongoing risks that new pasture varieties will become invasive, degrade natural ecosystems and escalate the cost of land management.  The paper urges governments, industry and farmers to take action now so that past land management mistakes are not repeated, or made worse.You can access the paper and supporting information.  The PNAS version can be found here.

Horse management in Australia’s high country is discussed in my recent article in The Conversation, co-authored by Dr Sam Banks.  It also documents our observation of cannibal horses……….

 NEWS:  This story was the winner in the ANU’s Strategic Communications and Public Affairs annual media awards night 2014 in the category “Quirkiest/Most Unusual Story”.  

The last forest skink died recently, representing the first reptile extinction in Australia.  John Woinarski, Hal Cogger and I argue in The Conversation that the legacy of this extinction should not be a shoulder shrug.
