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.

Too small to avoid catastrophic biodiversity meltdown

Chiew Larn

One of the perennial and probably most controversial topics in conservation ecology is when is something “too small’. By ‘something’ I mean many things, including population abundance and patch size. We’ve certainly written about the former on many occasions (see here, here, here and here for our work on minimum viable population size), with the associated controversy it elicited.

Now I (sadly) report on the tragedy of the second issue – when is a habitat fragment too small to be of much good to biodiversity?

Published today in the journal Science, Luke Gibson (of No substitute for primary forest fame) and a group of us report disturbing results about the ecological meltdown that has occurred on islands created when the Chiew Larn Reservoir of southern Thailand was flooded nearly 30 years ago by a hydroelectric dam.

As is the case in many parts of the world (e.g., Three Gorges Dam, China), hydroelectric dams can cause major ecological problems merely by flooding vast areas. In the case of Charn Liew, co-author Tony Lynam of Wildlife Conservation Society passed along to me a bit of poignant and emotive history about the local struggle to prevent the disaster.

“As the waters behind the dam were rising in 1987, Seub Nakasathien, the Superintendent of the Khlong Saeng Wildlife Sanctuary, his staff and conservationist friends, mounted an operation to capture and release animals that were caught in the flood waters.

It turned out to be distressing experience for all involved as you can see from the clips here, with the rescuers having only nets and longtail boats, and many animals dying. Ultimately most of the larger mammals disappeared quickly from the islands, leaving just the smaller fauna.

Later Seub moved to Huai Kha Khaeng Wildlife Sanctuary and fought an unsuccessful battle with poachers and loggers, which ended in him taking his own life in despair in 1990. A sad story, and his friend, a famous folk singer called Aed Carabao, wrote a song about Seub, the music of which plays in the video. 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.

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 ConservationBytes.com, 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 »





Biogeography comes of age

22 08 2013

penguin biogeographyThis week has been all about biogeography for me. While I wouldn’t call myself a ‘biogeographer’, I certainly do apply a lot of the discipline’s techniques.

This week I’m attending the 2013 Association of Ecology’s (INTECOL) and British Ecological Society’s joint Congress of Ecology in London, and I have purposefully sought out more of the biogeographical talks than pretty much anything else because the speakers were engaging and the topics fascinating. As it happens, even my own presentation had a strong biogeographical flavour this year.

Although the species-area relationship (SAR) is only one small aspect of biogeography, I’ve been slightly amazed that after more than 50 years since MacArthur & Wilson’s famous book, our discipline is still obsessed with SAR.

I’ve blogged about SAR issues before – what makes it so engaging and controversial is that SAR is the principal tool to estimate overall extinction rates, even though it is perhaps one of the bluntest tools in the ecological toolbox. I suppose its popularity stems from its superficial simplicity – as the area of an (classically oceanic) island increases, so too does the total number of species it can hold. The controversies surrounding such as basic relationship centre on describing the rate of that species richness increase with area – in other words, just how nonlinear the SAR itself is.

Even a cursory understanding of maths reveals the importance of estimating this curve correctly. As the area of an ‘island’ (habitat fragment) decreases due to human disturbance, estimating how many species end up going extinct as a result depends entirely on the shape of the SAR. Get the SAR wrong, and you can over- or under-estimate the extinction rate. This was the crux of the palaver over Fangliang He (not attending INTECOL) & Stephen Hubbell’s (attending INTECOL) paper in Nature in 2011.

The first real engagement of SAR happened with John Harte’s maximum entropy talk in the process macroecology session on Tuesday. What was notable to me was his adamant claim that the power-law form of SAR should never be used, despite its commonness in the literature. I took this with a grain of salt because I know all about how messy area-richness data can be, and why one needs to consider alternate models (see an example here). But then yesterday I listened to one of the greats of biogeography – Robert Whittaker – who said pretty much the complete opposite of Harte’s contention. Whittaker showed results from one of his papers last year that the power law was in fact the most commonly supported SAR among many datasets (granted, there was substantial variability in overall model performance). My conclusion remains firm – make sure you use multiple models for each individual dataset and try to infer the SAR from model-averaging. Read the rest of this entry »

Saving world’s most threatened cat requires climate adaptation

23 07 2013

The Iberian lynx is the world’s most threatened cat, with recent counts estimating only 250 individuals surviving in the wild. Recent declines of Iberian lynx have been associated with sharp regional reductions in the abundance of its main prey, the European rabbit, caused mainly by myxomatosis virus and rabbit haemorrhagic disease. At present, only two Iberian lynx populations persist in the wild compared with nine in the 1990s.

Over €90 million has been spent since 1994 to mitigate the extinction risk of this charismatic animal, mainly through habitat management, reduction of human-caused mortality and, more recently, translocation. Although lynx abundance might have increased in the last ten years in response to intensive management, a new study published in Nature Climate Change warns that the ongoing conservation strategies could buy just a few decades before the species goes extinct.

The study led by Damien Fordham from The Environment Institute (The University of Adelaide) and Miguel Araújo from the Integrative Biogeography and Global Change Group (Spanish Research Council) shows that climate change could lead to a rapid and severe decrease in lynx abundance in coming decades, and probably result in its extinction in the wild within 50 years. Current management efforts could be futile if they do not take into account the combined effects of climate change, land use and prey abundance on population dynamics of the Iberian Lynx.

Guilty until proven innocent

18 07 2013

precautionary principleThe precautionary principle – the idea that one should adopt an approach that minimises risk – is so ingrained in the mind of the conservation scientist that we often forget what it really means, or the reality of its implementation in management and policy. Indeed, it has been written about extensively in the peer-reviewed conservation literature for over 20 years at least (some examples here, here, here and here).

From a purely probabilistic viewpoint, the concept is flawlessly logical in most conservation questions. For example, if a particular by-catch of a threatened species is predicted [from a model] to result in a long-term rate of instantaneous population change (r) of -0.02 to 0.01 [uniform distribution], then even though that interval envelops r = 0, one can see that reducing the harvest rate a little more until the lower bound is greater than zero is a good idea to avoid potentially pushing down the population even more. In this way, our modelling results would recommend a policy that formally incorporates the uncertainty of our predictions without actually trying to make our classically black-and-white laws try to legislate uncertainty directly.

The economy worse off since 1978

3 07 2013

Can’t eat money

I was only a little tacker in 1978, and as any little tacker, I was blissfully unaware that I had just lived through a world-changing event. Just like that blissfully ignorant child, most people have no idea how important that year was.

It was around that year that humanity exceeded the planet’s capacity to sustain itself in perpetuity1. As I’ve just discovered today, it was also the same year that the per-capita Genuine Progress Indicator (GPI) peaked.

Now for a little detour and disclaimer before I explain all that. I’m not an economist, but I have a dabbled with the odd economic concept and bolted-on economic sub-routine in a few models I’ve written. Some would argue that conservation (i.e., the quest and methods needed to conserve biowealth) is almost entirely an economic pursuit, for economics is the discipline that attempts to explain (and modify) human behaviour. I tend to agree insofar as we now know enough on the biological side regarding how species become threatened and go extinct, and what kind of things we need to do to avoid losing more of the life-support system provided by biodiversity. Being completely practical about it, one could even argue that the biology part of conservation biology is complete – we should all now re-train as economists. While that notion probably represents a little hyperbole, it does demonstrate that economics is an essential endeavour in the fight to conserve our home.

Almost everyone has heard of ‘GDP’ – the Gross Domestic Product – as an indicator of economic ‘performance’, although most people have little idea what it actually measures (I’m including businesspeople and politicians here). GDP is merely the sum of marketed economic activity, which is only one small facet of the economy. For example, growing a tomato and preparing a salad for your family with it is not included, yet buying a frozen meal in the supermarket is. Even an oil spill increases GDP via increased expenditures associated with clean-up and remediation, when clearly it is not a ‘good’ thing for the economy on the whole because of the lost opportunities it causes in other sectors.

I fucking love biodiversity

18 06 2013

A corker of an idea, and post, from Diogo Veríssimo.

I don’t like biodiversity. I like beef lasagna, I like the British museum and I like everything Jules Verne ever wrote. When it comes to biodiversity, it’s different. I think about it all the time, try to be close to it and suffer emotional distress when I think of it going irretrievably away. This is LOVE.

Understanding how to get this passion across effectively has always been one of my main goals. That is why my research has focused on the links between marketing and conservation. But recently I started feeling a bit more empowered to take this mission seriously, and all thanks to the Facebook page I fucking love Science. This page became an internet sensation amassing more than 5 million fans and engaging frequently over 4 million users in any given week. Forget the New York Times and National Geographic, this is the real deal.

So I wondered, why can’t I do the same for biodiversity? The idea lingered in my head until I read a recent paper by McCallum and Bury on Google search patterns, which shows how even during the United Nations Decade on Biodiversity we are failing to mainstream biodiversity and its associated issues. If fact, people seem to be less interested. Whatever we are doing is clearly not working. So why not give this concept a try? And so I fucking love Biodiversity (IFLB) was born.

Australia’s national parks aren’t ‘national’ at all

14 06 2013

Yarra-Ranges-National-Park-AustraliaFollowing our The Conversation article a few weeks ago about the rapid demise of national parks in Australia, a few of us (me, Euan Ritchie & Emma Johnston) wrote a follow-up piece on the Australia’s national park misnomer (published simultaneously on The Conversation).

Australia boasts over 500 national parks covering 28 million hectares of land, or about 3.6% of Australia. You could be forgiven for thinking we’re doing well in the biodiversity-conservation game.

But did you know that of those more than 500 national parks, only six are managed by the Commonwealth Government? For marine parks, it’s a little more: 61 of the 130-plus are managed primarily by the Commonwealth. This means that the majority of our important biodiversity refuges are managed exclusively by state and territory governments. In other words, our national parks aren’t “national” at all.

In a world of perfect governance, this wouldn’t matter. But we’re seeing the rapid “relaxation” of laws designed to protect our “national” and marine parks by many state governments. Would making all of them truly national do more to conserve biodiversity?

One silly decision resulting in a major ecosystem disturbance in a national park can take decades if not hundreds of years to heal. Ecosystems are complex interactions of millions of species that take a long time to evolve – they cannot be easily repaired once the damage is done.

Almost overnight, Queensland, New South Wales and Victoria have rolled back nearly two centuries of park protection. What’s surprising here is that many of our conservation gains in the last few decades (for example, the Natural Heritage Trust, the National Reserve System, the Environment Protection and Biodiversity Conservation Act and a national marine reserve network) originated from Coalition policies.

Conservation hypocrisy

28 05 2013

Another soul-searching post from Alejandro Frid.

Confession time. This is going to be delicate, and might even ruffle some big feathers. Still, all of us need to talk about it. In fact, I want to trigger a wide conversation on the flaws and merits of what I did.

Back in March of this year I saw a posting for a job with the Smithsonian Conservation Biology Institute (SCBI) seeking a ‘conservation biologist to provide expert advice in the design and implementation of a Biodiversity Monitoring and Assessment Program (BMAP) in northern British Columbia, Canada’. The job sounded cool and important. I was suited for it, knew northern British Columbia well, and loved the idea of working there.

But there was a catch. The job was focused on the local impacts of fossil fuel infrastructure while dissociating itself from the climate impacts of burning that fuel, and involved collaborating with the fossil fuel company. According to the posting, this was not a new thing for the Smithsonian:

Guided by the principles of the Convention on Biological Diversity, SCBI works with a selected group of oil and gas companies since 1996 to develop models designed to achieve conservation and sustainable development objectives while also protecting and conserving biodiversity, and maintaining vital ecosystem services that benefit both humans and wildlife.

Given that climate change already is diminishing global biodiversity and hampering the ecosystem services on which we all depend, the logic seemed inconsistent to me. But there was little time to ponder it. The application deadline had just passed and my soft-money position with the Vancouver Aquarium Marine Science Centre was fizzling out. So I applied, hastily, figuring that I would deal with the issue later, if they ever got back to me. Read the rest of this entry »





Our national parks must be more than playgrounds or paddocks

24 05 2013

Convo TweetsIt’s interesting when a semi-random tweet by a colleague ends up mobilising a small army of scientists to get pissed off enough to co-write an article. Euan Ritchie of Deakin University started it off, and quickly recruited me, Mick McCarthy, David Watson, Ian Lunt, Hugh Possingham, Bill Laurance and Emma Johnston to put together the article. It’s a hugely important topic, so I hope it generates a lot of discussion and finally, some bloody action to stop the rapid destruction of this country’s national parks system.

Note: Published simultaneously on The Conversation.

It’s make or break time for Australia’s national parks.

National parks on land and in the ocean are dying a death of a thousand cuts, in the form of bullets, hooks, hotels, logging concessions and grazing licences. It’s been an extraordinary last few months, with various governments in eastern states proposing new uses for these critically important areas.

Australia’s first “National Park”, established in 1879, was akin to a glorified country club. Now called the “Royal National Park” on the outskirts of Sydney, it was created as a recreational escape for Sydney-siders, with ornamental plantations, a zoo, race courses, artillery ranges, livestock paddocks, deer farms, logging leases and mines.

Australians since realised that national parks should focus on protecting the species and natural landscapes they contain. However, we are now in danger of regressing to the misguided ideals of the 19th Century.

Parks under attack

In Victoria, new rules will allow developers to build hotels and other ventures in national parks. In New South Wales, legislation has been introduced to allow recreational shooting in national parks, and there is pressure to log these areas too. Read the rest of this entry »





A carbon economy can help save our species too

20 05 2013

money treeWe sent out this media release the other day, but it had pretty poor pick-up (are people sick of the carbon price wars?). Anyway, I thought it prudent to reprint here on CB.com.

Will Australia’s biodiversity benefit from the new carbon economy designed to reduce greenhouse gas emissions? Or will bio-‘perversities’ win the day?

“Cautious optimism” was the conclusion of Professor Corey Bradshaw, Director of Ecological Modelling at the University of Adelaide’s Environment Institute. He is lead author of a new paper published in the journal of Biological Conservation which reviewed the likely consequences of a carbon economy on conservation of Australian biodiversity.

“In most circumstances these two very important goals for Australia’s future – greenhouse gas emissions reduction and biodiversity conservation – are not mutually exclusive and could even boost each other,” Professor Bradshaw says.

“There are, however, many potential negative biodiversity outcomes if land management is not done with biodiversity in mind from the outset.”

The paper was contributed to by 30 Australian scientists from different backgrounds. They reviewed six areas where Australia’s Carbon Farming Initiative could have the greatest impact on biodiversity: environmental plantings; policies and practices to deal with native regrowth; fire management; agricultural practices; and feral animal control.

“The largest biodiversity ‘bang for our buck’ is likely to come from tree plantings,” says Professor Bradshaw. “But there are some potential and frightening ‘bioperversities’ as well. For example, we need to be careful not to plant just the fastest-growing, simplest and non-native species only to ‘farm’ carbon.

“Carbon plantings will only have real biodiversity value if they comprise appropriate native tree species and provide suitable habitats and resources for valued fauna. Such plantings could however risk severely altering local hydrology and reducing water availability.”

Professor Bradshaw says carefully managing regrowth of once-cleared areas could also produce a large carbon-sequestration and biodiversity benefit simultaneously. And carbon price-based modifications to agriculture that would benefit biodiversity included reductions in tillage frequency, livestock densities and fertiliser use, and retention and regeneration of native shrubs.

Help us restore a forest

12 04 2013

plantingI’m not usually one to promote conservation volunteer opportunities, but this is a little different. First, I’m involved in this one, and second, it’s very near to my home. As you might know, the Mount Lofty Ranges area has had about 90 % of its forests destroyed since European settlement, with a corresponding loss of ecosystem services. We need smart restoration on massive scale, and Monarto is one place where we can develop the best practices to achieve this goal. We really do need some help here, so I encourage anyone in the Adelaide area with an interest in evidence-based forest restoration to lend us a hand.

The Monarto Restoration Project will provide an internationally recognised opportunity to experience and engage with wild Australia as it was.

Our aim is restore and expand habitats at Monarto to represent what used to exist in the region before clearing for agriculture and the introduction of pest species. Monarto used to be teeming with wildlife. The remnant vegetation at Monarto is unique as it is located at the cross-over of two vegetation communities (the Mt Lofty Ranges and Murray Mallee). This means it provides important habitat for a range of threatened bird and plant species. However, there are still a number of species in danger of being lost from the area, so we need to focus on restoring habitat to support them too.

We provide an opportunity to see the bush in a way that is no longer possible in most parts of Australia. We hope to help you see what we have lost and encourage you to participate in conservation. It gives us the opportunity to include everyone in on-ground conservation work and pass on skills that can be applied beyond a day or this project. With your help we can reduce the impacts of pest species on the property and re-introduce some of the native species that are now locally extinct. Read the rest of this entry »

A tough little Eucalyptus porosa – one day soon this entire ex-paddock will be filled with carbon-guzzling natives. Note the plot markers in the background.

I had a great morning today checking out the progress of our carbon-biodiversity planting experiment out at Monarto Zoo. What a fantastic effort! Briony Horner and her team have made some amazing progress.

If you haven’t read about what we’re up to, here’s a brief re-cap:

Late last year we were awarded an Australian Research Council (ARC) Linkage Project grant in which we proposed to examine experimentally the cost-benefit trade-off between biodiversity and carbon using a replicated planting regime. The approach is quite simple, but it will take many years to pay off. What we are asking is: how many different species and in what densities are required to restore a native woodland from an over-grazed paddock that provide the biggest long-term biodiversity and carbon benefits simultaneously for the lowest costs?

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

12 03 2013

carbon farming 2I’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 »
