Game bird madness

4 11 2015

Gamecart_largeI just returned to Paris after a brief visit to the University of Aberdeen over the weekend. My hosts, Xavier Lambin and Beth Scott, were not only marvellously welcoming, I also learned a lot about the travesty that is game bird management in the United Kingdom, and especially in Scotland.

As you might already know, the Great Britons are a little cuckoo for birds — I’d even wager that the country produces more twitchers than any other country on Earth. The plus side is that there are few national taxa better censused and studied that British birds, because so many non-scientists get into the spirit of data collection. Hell, I’ve even had a play with some of their datasets.

The other side of this bird madness is not so good — I’m talking about the massive biomass of game birds reared, released and shot every year in the United Kingdom. It’s not the hunting per se with which I take issue, it’s the insane manipulation of an entire ecosystem for the benefit of a few species. Read the rest of this entry »

Killing the Koala and Poisoning the Prairie

19 10 2015


Man and the environment are meant for each other” — Tony Abbott, former Prime Minister of Australia (2014)

I know the human being and the fish can co-exist peacefully” — George W. Bush, former President of the USA (2000)

It. Has. Finally. Been. Published.

Yes, my new book with Paul Ehrlich, published by University of Chicago Press, is now available to purchase in book shops and online distributors around the world. The blog post today is a little explanatory synopsis of why we wrote the book and what it contains, but of course the real ‘meat’ is in the book. I hope you enjoy it.

In Australia, you can purchase the hard copy through Footprint Books, and the Kindle version at Amazon Australia. I also suggest that Australians might find the best deals through Booko. Electronic versions are also available through Kobo and Google Play. In the US you can order directly from University of Chicago Press, Amazon, Barnes & Noble, and many other book sellers. In the UK and Europe, the book is available from your country’s Amazon distributor. I imagine many chain and independent book sellers will be carrying the book by now, or will be soon.

My deepest thanks to all those who made it possible.

Our chance meeting in 2009 at Stanford University turned out to be auspicious, not least of which because of the publication this week of our co-authored book, Killing the Koala and Poisoning the Prairie. Australia, America and the Environment by University of Chicago Press. As a mid-career ecologist (Bradshaw) based at the University of Adelaide, it was indeed an honour to meet one of the most famous scientists (Ehrlich) in my field. With a list of books and hundreds of scientific papers under his belt, Ehrlich has been tackling major environmental issues since the 1960s. Ehrlich also has a long-time interest in Australia, having visited nearly every year during the last four decades and experienced more of the country than most Australians. Together we have observed firsthand the similarities and differences of Australia and the US, and the eyes we see through are trained as those of environmental scientists and evolutionary biologists.

So why write a book about the environmental tragedies currently unfolding in two completely different countries at opposite ends of the Earth? As it turns out, Australia and the US have much more in common environmentally than one might think, and not necessarily in a good way. Despite our vastly different floras and faunas, population densities, histories of human colonisation and soil productivities, there is an almost spooky similarity in the environmental and political problems both our countries are now experiencing. As such, we have a lot to learn about avoiding each other’s mistakes.


Australia and the contiguous US are roughly equivalent in land area, both cultures are derived originally and principally from what is now the United Kingdom, and both are examples of super-consuming, super-wasting, wealthy, literate countries. Both countries also have environmental footprints that exceed most other countries on Earth, with some of the world’s highest per capita rates of greenhouse-gas emissions, water consumption, species extinctions and deforestation.  Read the rest of this entry »

Australia’s perfect storm of negligence

17 03 2015

If, for the purposes of some sick and twisted thought experiment, you were to design policies that would ensure the long-term failure of a wealthy, developed nation, you wouldn’t have to look farther than Australia’s current recipe for future disaster. I’m not trying to be provocative, but the warning signs are too bold and flashy to ignore. Let’s just run through some of the main ones:

1. As the lambasted and thoroughly flawed 2015 Intergenerational Report clearly demonstrates, our current government has no idea about the future threats of climate change. Dragged kicking and screaming into only a symbolic recognition of some ‘distant and currently irrelevant problem’, the Abbott-oir and his intergenerational criminals are well known for killing the carbon-pricing scheme, dismantling the Department of Climate Change, pulling out of major international talks on climate-change mitigation and installing a half-arsed, ineffective policy that will do nothing to stem our emissions. Combine that with comments like “coal is good for humanity“, and it’s easy to see how our current leaders have little idea about the future mess they’re creating.

2. Not content just to kick the shit out of any meaningful climate action, our government has also turned its back on any renewable energy target, and facilitated the fossil-fuel barons to dig more coal out of the ground. While South Australia’s Royal Commission on the nuclear fuel cycle is a welcome candle in the climate change-mitigation darkness here, it is far from becoming a national priority any time soon.

3. As has been well documented, the Abbott-oir ship of fools has also done whatever it can to turn back decades of environmental protections in less than six months of taking office. Everything from opening up national parks for exploitation, failing to protect marine sanctuaries, limiting environmental checks to promoting logging in World Heritage Areas, there is little room for hope that our crumbling environmental system will improve at all in the near to long term.

What’s in a name? The dingo’s sorry saga

30 01 2015

bad dingoThe more I delve into the science of predator management, the more I realise that the science itself takes a distant back seat to the politics. It would be naïve to think that the management of dingoes in Australia is any more politically charged than elsewhere, but once you start scratching beneath the surface, you quickly realise that there’s something rotten in Dubbo.

My latest contribution to this saga is a co-authored paper led by Dale Nimmo of Deakin University (along with Simon Watson of La Trobe and Dave Forsyth of Arthur Rylah) that came out just the other day. It was a response to a rather dismissive paper by Matt Hayward and Nicky Marlow claiming that all the accumulated evidence demonstrating that dingoes benefit native biodiversity was somehow incorrect.

Their two arguments were that: (1) dingoes don’t eradicate the main culprits of biodiversity decline in Australia (cats & foxes), so they cannot benefit native species; (2) proxy indices of relative dingo abundance are flawed and not related to actual abundance, so all the previous experiments and surveys are wrong.

Some strong accusations, for sure. Unfortunately, they hold no water at all. Read the rest of this entry »

Help Hawaii’s hyper-threatened birds

You wouldn’t want to be a bird in Hawaii. There are more avian species threatened with extinction there than anywhere else in the USA. After humans arrived, some 70+ species have become extinct, and 31 are listed as threatened with extinction. In addition, 43% of 157 species are not native; among land birds, 69% are introduced species.

My friend, Cali Crampton asked me to promote their new crowdfunding project to reduce the threat of feral rats on Hawaiian birds. Please help if you can.

The Kaua‘i Forest Bird Recovery Project, a collaborative project of the Hawaii Department of Land and Natural Resources, Division of Forestry and Wildlife, the University of Hawaii Pacific Cooperative Studies Unit, and Garden Island Research and Development, has announced the launch of a crowdfunding and outreach campaign to generate support for protecting the native birds of Kaua’i by controlling rats with humane, self-resetting rat traps.

The campaign, named “Birds, not Rats!” runs through to 31 January 2015, with goals of increasing awareness of the threats that rats pose to birds and native ecosystems, and raising at least $10,000 for rat control through many small, individual donations.

Hawai’i is at the epicentre of the current global extinction crisis. Of the original 130+ native Hawaiian bird species, many have been lost forever, and only 11 are not yet endangered. Today, Kaua’i is home to eight native forest bird species, three of which are federally listed as endangered: the puaiohi or small Kaua’i thrush, the akeke’e or Kaua’i akepa, and the akikiki or Kaua’i creeper. Populations of these birds have plummeted as much as 90% in the last five years; the akikiki and the puaiohi now number fewer than 500 individuals, and the akeke’e numbers fewer than 1000 individuals. The Kaua’i Forest Bird Recovery Project’s goal is to reverse these declines. Read the rest of this entry »

InvaCost – estimating the economic damage of invasive insects

7 11 2014

insectinvasionThis is a blosh (rehash of someone else’s blog post) of Franck Courchamp‘s posts on an exciting new initiative of which I am excited to be a part. Incidentally, Franck’s spending the week here in Adelaide.

Don’t forgot to vote for the project to receive 50 000 € public-communication grant!

Climate change will make winters milder and habitats climatically more suitable year-round for cold-blooded animals like insects, but there are many questions remaining regarding whether such insects will be able to invade other regions as the climate shifts. There are many nasty bugs out there.

For example, the Asian predatory wasp is an invasive hornet in Europe that butchers pollinating insects, especially bees, thereby affecting the production of many wild and cultivated plants. I hope that we all remember what Einstein said about pollinators:

If bees were to disappear, humans will disappear within a few years.

(we all should remember that because it’s one of the few things he said that most of us understood). The highly invasive red fire ant is feared for its impacts on biodiversity, agriculture and cattle breeding, and the thousands of anaphylactic shocks inflicted to people by painful stings every year (with hundreds of deaths). Between the USA and Australia, over US$10 billion is spent yearly on the control of this insect alone. Tiger mosquitoes are vectors of pathogens that cause dengue fever, chikungunya virus and of about 30 other viruses. We could go on.

Most of these nasty creatures are now unable to colonise northern regions of Europe or America, or southern regions of Australia, for example, because they cannot survive cold temperatures. But how will this change? Where, when and which species will invade with rising temperatures? What will be the costs in terms of species loss? In terms of agricultural or forestry loss? In terms of diseases to cattle, domestic animals and humans? What will be the death toll if insects that are vectors of malaria can establish in new, highly populated areas?

We’ve proposed to study these and others from a list of 20 of the worst invasive insect species worldwide, and we got selected (i.e., financed!) by the Fondation BNP Paribas. In addition, the Fondation BNP Paribas has selected five scientific programmes on climate change and will give 50,000 € (that’s US$62,000) to the one selected by the public, for a communication project on their scientific programme. This is why we need you to vote for our project: InvaCost. Read the rest of this entry »

It’s not all about cats

20 10 2014

Snake+OilIf you follow any of the environment news in Australia, you will most certainly have seen a lot about feral cats in the last few weeks. I’ve come across dozens of articles in the last week alone talking about the horrendous toll feral cats have had on Australian wildlife since European arrival. In principle, this is a good thing because finally Australians are groggily waking to the fact that our house moggies and their descendants have royally buggered our biodiversity. As a result, we have the highest mammal extinction rate of any country.

But I argue that the newfound enthusiasm for killing anything feline is being peddled mainly as a distraction from bigger environmental issues and to camouflage the complete incompetence of the current government and their all-out war on the environment.

Call me cynical, but when I read headlines like “Australia aims to end extinction of native wildlife by 2020” and Environment Minister Hunt’s recent speech that he has “… set a goal of ending the loss of mammal species by 2020“, I get more than just a little sick to the stomach.

What a preposterous load of shite. Moreover, what a blatant wool-pulling-over-the-eyes public stunt. Read the rest of this entry »
