A convenient truth: global push for carbon-based conservation

19 05 2014

Eucalyptus viminalis (Manna Gum) - leaf, adultI’ve just written an article for the Australian River Restoration Centre‘s RipRap magazine, and they have given me permission to reproduce it here.

The brave, new green world of the carbon economy hasn’t exactly taken off as desired. Perhaps it’s because it wasn’t really planned from the outset, or maybe it is still too abstract for most people to accept, digest and incorporate into their daily lives. An emergent property of society’s generally slow awakening to the challenge of climate disruption, is that it will be a long time before we accept its full suite of incarnations.

The infant carbon economy is, however, well and truly alive and kicking, so it is important to try and plan for its growing influence on our decision making. Bumps in the road aside, the carbon economy has mostly been a blessing (actual and potential) for biodiversity conservation projects the world over.

In principle, the aim of the carbon economy is rather straight-forward: charge people a certain amount for each unit of carbon dioxide equivalents they release, and then use that money to develop approaches that further increase carbon sequestration or limit emissions. It’s a ‘build-it-and-they-will-come’ framework, where increasing financial impetus to restrict emissions is enhanced by society’s evolution towards better approaches and technology.

The operational side of the carbon economy is unfortunately much more muddled, with vested interests and political gaming weakening its implementation. Nonetheless, we persevere. Read the rest of this entry »





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 the podcast of my slideshow for general viewing here. I’ve also highlighted some key points from the talk below: Read the rest of this entry »





Incentivise to keep primary forests intact

7 02 2014

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 Mongabay.com 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

Mongabay.com: 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.

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.

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:

Quantity, but not quality – slow recovery of disturbed tropical forests

8 11 2013

tropical regrowthIt is a sobering statistic that most of the world’s tropical forests are not ‘primary’ – that is, those that have not suffered some alteration or disturbance from humans (previously logged, cleared for agriculture, burned, etc.).

Today I highlight a really cool paper that confirms this, plus adds some juicy (and disturbing – pun intended – detail). The paper by Phil Martin and colleagues just published in Proceedings of the Royal Society B came to my attention through various channels – not least of which was their citation of one of our previous papers ;-), as well as a blog post by Phil himself. I was so impressed with it that I made my first Faculty of 1000 Prime recommendation1 of the paper (which should appear shortly).

As we did in 2011 (to which Phil refers as our “soon-to-be-classic work” – thanks!), Martin and colleagues amassed a stunning number of papers investigating the species composition of disturbed and primary forests from around the tropics. Using meta-analysis, they matched disturbed and undisturbed sites, recording the following statistics: Read the rest of this entry »





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.
