South Australia’s tattered environmental remains

State budget percentage expenditures for health, education and environment

South Australia State budget percentage expenditures for health, education and environment

Yesterday I gave the second keynote address at the South Australia Natural Resource Management (NRM) Science Conference at the University of Adelaide (see also a brief synopsis of Day 1 here). Unfortunately, I’m missing today’s talks because of an acute case of man cold, but at least I can stay at home and work while sipping cups of hot tea.

Many people came up afterwards and congratulated me for “being brave enough to tell the truth”, which both encouraged and distressed me – I am encouraged by the positive feedback, but distressed by the lack of action on the part of our natural resource management leaders.

The simple truth is that South Australia’s biodiversity and ecosystems are in shambles, yet few seem to appreciate this.

So for the benefit of those who couldn’t attend, I’ve uploaded my slideshow for general viewing here, and I understand that a podcast might be available in the very near future. I’ve also highlighted some key points from the talk below: Read the rest of this entry »

Eye on the taiga

24 03 2014

boreal damageDun! Dun, dun, dun! Dun, dun, dun! Dun, dun, daaaaah!

I’ve waited nearly two years to do that, with possibly our best title yet for a peer-reviewed paper: Eye on the taiga: removing global policy impediments to safeguard the boreal forest (recently published online in Conservation Letters).

Of course, the paper has nothing to do with cheesy Eighties music, underdog boxers or even tigers, but it does highlight an important oversight in world carbon politics. The boreal forest (also known as taiga from the Russian) spans much of the land mass of the Northern Hemisphere and represents approximately one quarter of the entire planet’s forests. As a result, this massive forest contains more than 35% of all terrestrially bound carbon (below and above ground). One doesn’t require much more information to come to the conclusion that this massive second lung of the planet (considering the Amazon the first lung) is a vital component of the world’s carbon cycle, and temperate biodiversity.

The boreal forest has been largely expanding since the retreat of the glaciers following the Last Glacial Maximum about 20,000 years ago, which means that its slow progression northward has produced a net carbon sink (i.e., it takes up more atmospheric carbon that it releases from decomposition). However, recent evidence suggests that due to a combination of increased deforestation, fire from both human encroachment and climate change, mass outbreaks of tree-killing insects and permafrost melting, the boreal forest is tipping towards becoming a net carbon source (i.e., emitting more carbon into the atmosphere than it takes up from photosynthesis). This is not a good thing for the world’s carbon cycle, because it means yet another positive feedback that will exacerbate the rapid warming of the planet. Read the rest of this entry »

Lose biodiversity and you’ll get sick

14 03 2014

dengueHere’s a (paraphrased) recommendation I did recently for F1000 about a cool avenue of research I’ve been following for a few years now. Very interesting, but much, much more to do.

The core concepts of conservation ecology are well-established: we know that habitat lossfragmentation, invasive species, over-exploitation and of course, climate change, are bad for biodiversity. This well-quantified scientific baseline has led the discipline recently to embark on questions pertaining more to the (a) implications of biodiversity loss for humanity and (b) what we can do to offset these. A recent paper by Morand and colleagues addresses perhaps one of the most compelling reasons that human society should appreciate biodiversity beyond its intrinsic value; as biodiversity degrades, so too does human health.

Some argue that the only way to convince society in general that biodiversity is worth protecting is that we link its loss directly to degrading human health, wealth and well-being. Confirmation of such relationships at a variety of spatial and temporal scales is therefore essential. Morand and colleagues used data from a variety of sources to test two predictions: (1) that the number of infectious disease should increase as overall biodiversity increases and (2) that biodiversity loss, inferred from species threat and deforestation data, should increase the number of infectious disease outbreaks in humans. Using data from 28 countries in the Asia-Pacific region, they confirmed both predictions. Read the rest of this entry »

Alliance of Leading Environmental Researchers and Thinkers

11 03 2014

ALERTIf you’ve been following this blog or my Twitter feed over the last few weeks, you’ve surely noticed a few references to A.L.E.R.T. – the Alliance of Leading Environmental Researchers and Thinkers. You might also have asked yourself, what exactly is ALERT, and is it something I should pay attention to?

Today’s post attempts to explain this new organisation, and hopefully convince you that the answer to the second question is ‘yes’.

Several months ago, a slightly cryptic e-mail from eminent conservation biologist, Bill Laurance, arrived in my inbox. It asked – what do you think of this logo (see associated image)? A few e-mails later and a couple of minor tweaks, and we ended up with what I thought was a pretty cool logo for this new ‘ALERT’ thing. It wasn’t until quite some time later that I finally understood what Bill was attempting to create.

Is ALERT a news aggregator, a blog, an advocacy group, a science-communication resource or a science-policy interface? Why, yes it is!

Australia’s (latest) war on the environment

3 03 2014

monkYes, the signs were there, but they weren’t clandestine messages written in the stars or in the chaos of tea-leaf dregs. We saw this one coming, but Australians chose to ignore the warning signs and opt for the American political model of extremism, religiosity, plutocracy and science denial.

Enter the ‘Tea Party’ of Australia – the ‘new’ Coalition where reigning Rex perditor Prime Minister Tony The Monk Abbott1 has, in just a few short months, turned back the clock on Australian environmental protection some 40 years.

Yes, we saw it coming, but it wasn’t a tautological fait accompli just because it concerned a ‘conservative’ government. It’s difficult to remember, I know, that conservative governments of yesteryear implemented some strikingly powerful and effective environmental legislation. Indeed, it was the former incarnation of the Coalition government that implemented the once-formidable Environmental Protection and Biodiversity Conservation (EPBC) Act under the direction of then Environment Minister, Robert Hill. A colossus of sorts, the EPBC suffers from many ailments. While it’s the only really bitey environmental legislation we’ve got, that colossus is a lumbering, limping giant missing more than a few teeth – it needs a complete overhaul.

As most Australians are unfortunately aware, The Monk repeatedly and defiantly promised to repeal the Labor-government carbon price implemented in July 2012, despite the absolute necessity to tax the heaviest pollutersWhile somewhat sheepish about his recent climate disruption denialism following his election in 2013, a denialist he remains:

Incentivise to keep primary forests intact

7 02 2014

The Amazon rainforest. Photo by Rhett A. Butler

I know – ‘incentivise’ is one of those terrible wank words of business speak. But to be heard by the economically driven, one must learn their guttural and insensitive language. I digress …

Today’s post is merely a repost of an interview I did for the new series ‘Next Big Idea in Forest Conservation‘. I’m honoured to have been selected for an interview along with the likes of Bill Laurance and Stuart Pimm.

Consider this my conservation selfie.

An Interview with Corey Bradshaw What is your background?

Corey Bradshaw: I have a rather eclectic background in conservation ecology. I grew up in the wilds of western Canada, the son of a trapper. My childhood experiences initially gave me a primarily consumptive view of the environment from trapping, fishing and hunting, but I learned that without intact environmental functions, these precious resources quickly degrade or disappear. This ironic appreciation of natural processes would later lead me into academia and the pursuit of reducing the rate of the extinction crisis.

I completed my first degrees in ecology in Montréal and the University of Alberta, followed by a PhD in New Zealand at the University of Otago. After deciding to pursue the rest of my career in the Southern Hemisphere, I completed my postdoctoral fellowship at the University of Tasmania. Multiple field seasons in the subantarctic and Antarctica probably assisted in a giving me a burgeoning desire to change gears, so I left for the tropics of northern Australia to begin a position at Charles Darwin University. Being introduced there to conservation greats like Navjot Sodhi (sadly, now deceased), Barry Brook and David Bowman turned my research interests on their ear. I quickly became enamoured with quantitative conservation ecology, applying my skills in mathematics to the plight of the world’s ecosystems. Nowhere did the problems seem more intractable than in the tropics.

I am now based at the University of Adelaide (since 2008) and have a vibrant research lab where we apply our quantitative skills to everything from conservation ecology, climate change, energy provision, human population trends, ecosystem services, sustainable agriculture, human health, palaeoecology, carbon-based conservation initiatives and restoration techniques. How long have you worked in tropical forest conservation and in what geographies? What is the focus of your work? Read the rest of this entry »

Terrestrial biodiversity’s only chance is avoided deforestation

24 01 2014

farming forestsToday I was shocked, stunned and pleasantly (for a change) surprised. Australia has its first ‘avoided deforestation’ carbon farming project.

It is understandable that this sort of news doesn’t make the Jane & Joe Bloggs of the world stand up and cheer, but it should make conservation biologists jump for bloody joy.

So why exactly am I so excited about the setting aside of a mere 9000 ha (90 km2, or 10 × 9 km) of semi-arid scrub in western New South Wales? It’s simple – nothing can replace the biodiversity or carbon value of primary forest. In other words, forest restoration – while laudable and needed – can never achieve what existing forest already does. We know now from various parts of the world that biodiversity is nearly always much higher in primary forest, and that the carbon structure of the forest (especially below-ground carbon) can take centuries to recover.

Another problem with restoration – and if you’ve ever been involved in any tree planting yourself, you’ll know what I mean – is that it’s incredibly expensive, time-consuming and slow. Wouldn’t it make more financial sense just to save forests instead of trying to rebuild them?

Of course it is, so the logical conclusion from a conservation perspective is to save primary forest first, then worry about restoration next. The problem is, there are few, if any, financial incentives for keeping forests standing in the private sector. The stumbling rise of the carbon economy is a potential resolution to this problem, although neither the Kyoto Protocol nor most national carbon-trading schemes adequately account for the carbon value of existing forests.

Up until today, even Australia didn’t have any examples.

You know it’s hot when it’s too hot to ….

My post’s title might be a good candidate title for a punk song in the 2030s (maybe by a re-incarnation of the Dead Kennedys).

I am currently sitting under my solar-powered ceiling fan as Adelaide is declared the world’s hottest city (and not in the funky, cultural, fun way), and I can’t help but contemplate climate change models predicting the fate of biodiversity over the coming decades. Because it’s far, far too hot to work outside, I’m perusing the latest interesting articles on the subject and I came across this recent little gem.

Also recommended on F1000Prime by Ary Hoffman, the paper, Using physiology to predict the responses of ants to climatic warming, by Sarah Diamond and colleagues touches on many aspects of climate predictions that need to be considered. I summarise these briefly here.

While no physiologist, I have dabbled in the past, although up until quite recently I didn’t see that physiology per se had much to do with conservation. It turns out that climate change has spawned an entire sub-discipline called ‘conservation physiology‘, which focuses inter alia on how species can/will/might respond and adapt to a warmer, climatically disrupted world.

What struck me about Diamond & colleagues’ paper was that yet again, it’s not as simple as heat-stressing a species experimentally and making a prediction on its future distribution (ecology is complex). No, the complexity comes in various forms that makes each species a little different from each other. Using North American ant species subjected to various warming scenarios in large (5 m) enclosures, they found the following: Read the rest of this entry »

Essential role of carnivores on the wane

10 01 2014

This interesting review has just come out in Science, and because I was given a heads-up about it, I decided to do a F1000 recommendation. That’s more or less what follows, with some additional thoughts.

Ripple and colleagues can perhaps be excused for stating what might appear to many ‘in the biz’ to be blatantly obvious, but their in-depth review of the status of the world’s carnivores is a comprehensive overview of this essential guild’s worldwide plight. It not only represents an excellent teaching tool, the review elegantly summarises the current status of these essential ecosystem engineers.

The world’s 245 terrestrial carnivores might seem to be ecologically redundant to the informed given their natural rarity, low densities and cryptic behaviour, but nothing could be farther from the truth. Ecologists have only within the last decade or so revealed the essential ecosystem functions of these species (see former posts on here, here and here). The review focuses on the largest and most well-studied species, but the trends likely apply across most of the order. Read the rest of this entry »

More species = more resilience

8 01 2014

reef fishWhile still ostensibly ‘on leave’ (side note: Does any scientist really ever take a proper holiday? Perhaps a subject for a future blog post), I cannot resist the temptation to blog about our lab’s latest paper that just came online today. In particular, I am particularly proud of Dr Camille Mellin, lead author of the study and all-round kick-arse quantitative ecologist, who has outdone herself on this one.

Today’s subject is one I’ve touched on before, but to my knowledge, the relationship between ‘diversity’ (simply put, ‘more species’) and ecosystem resilience (i.e., resisting extinction) has never been demonstrated so elegantly. Not only is the study elegant (admission: I am a co-author and therefore my opinion is likely to be biased toward the positive), it demonstrates the biodiversity-stability hypothesis in a natural setting (not experimental) over a range of thousands of kilometres. Finally, there’s an interesting little twist at the end demonstrating yet again that ecology is more complex than rocket science.

Despite a legacy of debate, the so-called diversity-stability hypothesis is now a widely used rule of thumb, and its even implicit in most conservation planning tools (i.e., set aside areas with more species because we assume more is better). Why should ‘more’ be ‘better’? Well, when a lot of species are interacting and competing in an ecosystem, the ‘average’ interactions that any one species experiences are likely to be weaker than in a simpler, less diverse system. When there are a lot of different niches occupied by different species, we also expect different responses to environmental fluctuations among the community, meaning that some species inherently do better than others depending on the specific disturbance. Species-rich systems also tend to have more of what we call ‘functional redundancy‘, meaning that if one species providing an essential ecosystem function (e.g., like predation) goes extinct, there’s another, similar species ready to take its place.

Biowealth: all creatures great and small

4 12 2013

Curious Country flyer“So consider the crocodiles, sharks and snakes, the small and the squirmy, the smelly, slimy and scaly. Consider the fanged and the hairy, the ugly and the cute alike. The more we degrade this astonishing diversity of evolved life and all its interactions on our only home, the more we expose ourselves to the ravages of a universe that is inherently hostile to life.”

excerpt from ‘Biowealth: all creatures great and small’ The Curious Country (C.J.A. Bradshaw 2013).

I’ve spent the last few days on the east coast with my science partner-in-crime, Barry Brook, and one of our newest research associates (Marta Rodrigues-Rey Gomez). We first flew into Sydney at sparrow’s on Monday, then drove a hire car down to The ‘Gong to follow up on some Australian megafauna databasing & writing with Bert Roberts & Zenobia Jacobs. On Tuesday morning we then flitted over to Canberra where we had the opportunity to attend the official launch of a new book that Barry and I had co-authored.

The book, The Curious Country, is an interesting experiment in science communication and teaching dreamed up by Australia’s Chief Scientist, Professor Ian Chubb. Realising that the average Aussie has quite a few questions about ‘how stuff works’, but has little idea how to answer those questions, Ian engaged former Quantum star and science editor, Leigh Dayton, to put together a short, punchy, topical and easily understood book about why science is good for the country.

Yes, intuitive for most of you out there reading this, but science appreciation isn’t always as high as it should be amongst the so-called ‘general public’. Ian thought this might be one way to get more people engaged.

When honoured with the request to write an interesting chapter on biodiversity for the book, I naturally accepted. It turns out Barry was asked to do one on energy provision at the same time (but we didn’t know we had both been asked at the time). Our former lab head, Professor David Bowman, was also asked to write a chapter about fire risk, so it was like a mini-reunion yesterday for the three of us.

King for a day – what conservation policies would you make?

29 11 2013

CrownI have been thinking a lot lately about poor governance and bad choices when it comes to biodiversity conservation policy. Perhaps its all that latent anger arising from blinkered, backward policies recently implemented by conservative state and national governments in Australia and elsewhere that leads me to contemplate: What would I do if I had the power to change policy?

While I am certain I have neither the experience or complete knowledge to balance national budgets, ensure prosperity and maintain the health of an entire country, I do have some ideas about what we’re doing wrong conservation-wise, and how we could potentially fix things. This is not meant to be an exhaustive list – it is more a discussion point where people can suggest their own ideas.

So here are 16 things I’d change or implement (mainly in Australia) if I were king for a day:

Medieval Canada threatens global biodiversity

25 11 2013

harper_scienceArtists, poets and musicians make us feel, viscerally, how people destroy what they do not understand. Logic and observation led E. O. Wilson to conclude: ‘If people don’t know, they don’t care. If they don’t care, they don’t act.’

Whether you feel it in one of Drew Dillinger’s poems1 or visualise it from the sinuous beauty of mathematical equations, the song remains the same. Scientists are critical to the present and future of the biosphere and humanity, but if — and only if — we are free to communicate our findings to the voting public.

Galileo did not have that right. Scientists in totalitarian regimes of today still lack it. And now, incredibly, some of Canada’s top scientists have lost that right2,3,4.

That is not the Canada I immigrated into. Rewind the tape to 1983. I am a young immigrant, ecstatic that my family has gained entry into the country. We all have mixed feelings; we love our home country of Mexico and are sad to leave it, yet we look forward to being part of Canada’s open-minded and science-loving spirit. The tape runs forward and not all turns out to be as advertised. Still, for the next 23 years Canada remains a damn good place, ruled by governments that, imperfect as they might have been, were not obsessed with burying science.

Fast forward the tape to 2006. Stephen Harper’s newly elected and still ruling Conservative Government hits the ground pounding punches in all directions. Almost immediately, the Conservatives begin to implement one of their many Machiavellian tactics that aim to turn Canada into a petro-state6,7: downgrade science as irrelevant to evidence-based decision making. Ever since, Canadian federal scientists have seen their programs slashed or buried. Those who manage to hang on to their jobs are strictly forbidden to speak about their findings to the media or the public8,9,10,11.

Cleaning up the rubbish: Australian megafauna extinctions

15 11 2013

diprotodonA few weeks ago I wrote a post about how to run the perfect scientific workshop, which most of you thought was a good set of tips (bizarrely, one person was quite upset with the message; I saved him the embarrassment of looking stupid online and refrained from publishing his comment).

As I mentioned at the end of post, the stimulus for the topic was a particularly wonderful workshop 12 of us attended at beautiful Linnaeus Estate on the northern coast of New South Wales (see Point 5 in the ‘workshop tips’ post).

But why did a group of ecological modellers (me, Barry Brook, Salvador Herrando-Pérez, Fréd Saltré, Chris Johnson, Nick Beeton), ancient DNA specialists (Alan Cooper), palaeontologists (Gav Prideaux), fossil dating specialists (Dizzy Gillespie, Bert Roberts, Zenobia Jacobs) and palaeo-climatologists (Michael Bird, Chris Turney [in absentia]) get together in the first place? Hint: it wasn’t just the for the beautiful beach and good wine.

I hate to say it – mainly because it deserves as little attention as possible – but the main reason is that we needed to clean up a bit of rubbish. The rubbish in question being the latest bit of excrescence growing on that accumulating heap produced by a certain team of palaeontologists promulgating their ‘it’s all about the climate or nothing’ broken record.

Translocations: keep it in the family

31 10 2013
Prairie dogs (Cynomys spp.) comprise 5 species native to North American grasslands. Rather than a ‘dog’ (‘perrito’ or ‘little dog’ in Spanish), this animal is a squirrel (Sciuridae) adapted to ground life. In particular, black-tailed prairie dogs (C. ludovicianus) inhabit the plains between the Frenchman River in Canada and the Mexican stretches of the Sonoran and Chihuahuan deserts. Individuals have a maximum length of 40 cm and weigh up to 2 kg. The global population is currently estimated at some 18 million individuals over an area that has waned by 90% relative to historical ranges. The species is IUCN ‘Least Concern’ and shows a global ‘decreasing’ trend as a result of ongoing habitat loss and fragmentation due to urban development and farming, and susceptibility to Yersinia pestis – a bacteria that causes plague in prairie dogs and other mammals including humans.Colonies, known as ‘coteries’ (from French), are made of several family clans that live in contiguous territories. Clans include one or two males, and several females and juveniles [7]. Females show strong philopatry, while males are the ones that colonise new territories, or mingle with existing clans. Such dispersion pattern, along with daughters deliberately avoiding incest, minimises inbreeding [8]. Burrows consist of >10-m tunnels in which temperatures remain between 5 and 25 ºC irrespective of above-ground temperatures. Prairie dogs are genuine landscape architects with their network of burrows largely increasing edaphic, botanic and zoological diversity [9]. The pic shows two black prairie dogs in Wind Cave National Park (South Dakota, USA) (courtesy of Lisa Savage).

If you have lived in different suburbs, cities or even countries, you will be well aware that changing residence feels very different whether you do it on your own or with someone else. In the latter case, you might have to share tasks, and key decisions have to be made on the basis of everybody’s needs. The situation is analogous when managers decide to move a group of animals or plants from one place to another – so-called translocation.

Translocations involve human-assisted movements of organisms into an area (i) that holds an existing population of the same species (re-stocking), or (ii) where the species has been extirpated (re-introduction) or (iii) is outside its historical distribution (introduction) [1] – this terminology follows 1993 IUCN’s Criteria [1, 3], but is unstable, e.g., see [2]. The rationale behind translocations has obvious merits (e.g., to promote population growth following overharvesting, attenuate human-predator conflicts, rescue endangered species) [2]. However, translocations are complex and have a long record of failed attempts in the history of conservation biology, so the resulting waste of resources has prompted a recent re-appraisal of methods [1-3].

Debra Shier investigated the nuisances of a translocation of a social species such as the black-tailed prairie dog (Cynomys ludovicianus) [4]. Shier tagged, sexed and determined (via capture-recapture and field observations) membership to identified family clans in 973 individuals from Vermejo Park (New Mexico, USA). She then introduced clans to ten dog-free sites with soil quality and vegetation cover akin to the historical distribution of the species. In five of those sites, Shier translocated family clans (4 to 7 individuals per clan) and in the other five sites she freed clans made up of members being picked up randomly (1 male, 2 females, 2 juveniles). During a period of 9-10 months after translocation, Shier monitored the behaviour of females and ultimately re-captured all introduced individuals. She found that 50% of the dogs had survived translocation, and assumed that the remainder had died since individuals rarely disperse more than three km from their natal area, and aerial surveys spotted no dogs in a four-km perimeter around the point of release.

Conservation: So easy a child could do it

13 09 2013

child's playI don’t like to talk about my family online. Call me paranoid, but there are a lot of crazy people out there who don’t like what scientists like me are saying (bugger the evidence). Yes, like many climate scientists, I’ve also been threatened. That’s why my personal life remains anonymous except for a select group of people.

But I’ve mentioned my daughter before on this blog, and despite a few people insinuating that I am a bad parent because of what I said, I am happy that I made the point that climate change is a scary concept of which our children must at least be cognisant.

My daughter’s story today is a little less confronting, but equally enlightening. It’s also a little embarrassing as a scientist who has dedicated my entire research career to the discipline of conservation biology.

As a normal six year-old without the ability to refrain from talking – even for a moment – I hear a lot of stories. Many of them are of course fantastical and ridiculous, but those are just part of a healthy, imaginative childhood (I am proud to say though that she is quite clear about the non-existence of fictitious entities like faeries, easter bunnies and gods).

Every once in a while, however, there are snippets of wisdom that ooze out from the cracks in the dross. In the last few months, my daughter has independently and with no prompting from me come up with two pillars of conservation science: (i) protected areas and (ii) biodiversity corridors.

DNA barcoding plants with citizen science

28 08 2013

hikingI was contacted recently by Oscar Jaslowski of Microryza (a web platform that allows scientists to post research  ideas and collect contributions from web visitors) about a project getting underway in Alaska by Ellen Jorgensen of Genspace. He suggested it might make a good post for, and I agreed. Thanks for the contribution, Ellen & Oscar.

There’s nothing so final as watching the bush pilot take off in his tiny plane, leaving you stranded in the Alaskan backcountry. We had plenty of food for a three-day expedition, but no satellite phone or any other way to contact anyone. In Alaska, the phrase ‘primordial indifference’ pretty much sums up your relationship with the vast, glacier-carved landscape. Mother Nature does not care if an ant like you lives or dies.

Our destination, the Skolai Valley, is located about 480 km (300 miles) east of Anchorage, in the heart of Wrangell-St. Elias National Park. At a whopping 5.3 million hectares (13 million acres), it is the largest national park in the United States, and probably one of the least-visited. Much of its forbidding territory is snow-covered and similar to the Himalayas. In fact, the size of the massive ice fall that towers over the town of McCarthy, the origin of our flight, is exceeded only by one near Mt. Everest. But winding through the glaciers and snowfields are alpine valleys that are a backpacker’s dream. And Genspace, the nonprofit science-based organisation that I direct, was lucky enough to have received funding in 2012 to launch this expedition to Skolai.

Our  mission: to barcode wild Alaskan plant life. Two of us headed down into the river valley and the other two climbed up to the level of the mountain pass to survey more alpine vegetation. We were carrying portable plant presses – normally something too bulky for backpacking, but necessary for this trip. Read the rest of this entry »
