Eye on the taiga

24 03 2014

Dun! 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 »

Terrestrial biodiversity’s only chance is avoided deforestation

24 01 2014

Today 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.

Brave new green world: biodiversity’s response to Australia’s carbon economy

12 03 2013

I’ve had a busy weekend entertaining visiting colleagues and participating in WOMADelaide‘s first-ever ‘The Planet Talks‘. If you haven’t heard of WOMADelaide, you’re truly missing out in one of the best music festivals going (and this is from a decidedly non-festival-going sort). Planet Talks this year was a bit of an experiment after the only partially successful Earth Station festival held last year (it was well-attended, but apparently wasn’t as financially successful as they had hoped). So this year they mixed a bit of science with a bit of music – hence ‘Planet Talks’. Paul Ehrlich was one of the star attractions, and I had the honour of going onstage with him yesterday to discuss a little bit about human population growth and sustainability. It was also great to see Robyn Williams again. All the Talks were packed out – indeed, I was surprised they were so popular, especially in the 39-degree heat. Rob Brookman, WOMADelaide’s founder and principal organiser, told me afterward that they’d definitely be doing it again.

But my post really isn’t about WOMADelaide or The Planet Talks (even though I got the bonus of meeting one of my favourite latin bands, Novalima, creators of one of my favourite songs). It’s instead about a paper I heralded last year that’s finally been accepted.

In early 2012 at the Terrestrial Ecosystem Research Network (TERN) symposium in Adelaide, the Australian Centre for Ecological Analysis and Synthesis (ACEAS) put on what they called the ‘Grand Challenges’ workshop. I really didn’t get the joke at the time, but apparently the ‘grand challenge’ was locking 30 scientists with completely different backgrounds in a room for two days to see if they could do anything other than argue and bullshit. Well, we rose to that challenge and produced something that I think is rather useful.

I therefore proudly introduce the paper entitled Brave new green world: consequences of a carbon economy for the conservation of Australian biodiversity just accepted in Biological Conservation. The online version isn’t quite ready yet (should be in the next few weeks), but you are welcome to request a preprint from me now. If you attended (the surprisingly excellent) TERN symposium in Canberra last month, you might have seen me give a brief synopsis of our results.

The paper is a rather in-depth review of how we, 30 fire, animal, plant, soil, landscape, agricultural and freshwater biologists, believe Australia’s new carbon-influenced economy (i.e., carbon price) will impact the country’s biodiversity. Read the rest of this entry »

Get boreal

7 06 2012

I’ve been a little quiet this last week because I’ve had to travel to the other side of the planet for what turned out to be a very interesting and scientifically lucrative workshop. After travelling 31 hours from Adelaide to Umeå in northern Sweden, I wondered to myself if it was going to be worth it for a 2.5-day workshop on a little island (Norrbyskär) in the Baltic Sea (which, as it turned out, didn’t have internet access).

The answer is a categorical ‘yes’!

Many of you know that I’ve dabbled in boreal forest conservation in the past, but I could never claim any real expertise in the area. Hence it came as something of a shock when Jon Moen of Umeå University asked me to attend a specialist workshop focused loosely on making the plight and importance of the boreal forest more widely acknowledged. I dragged my feet initially, but Jon convinced me that I could add something to the mix.

It was a small workshop, but well-represented by all boreal countries save Norway (i.e., we had Russians, Swedes, Finns, Canadians and Americans – this Australian was indeed the odd one out). We also had a wide array of expertise, from carbon accountants, political scientists, political economists, native cultures experts, ecologists to foresters. Our mandate – justify why we should pay more attention to this globally important region.

Just how important is the boreal forest? We managed to unearth some little-appreciated facts: Read the rest of this entry »
