Road traffic is a threat to Tasmania’s few health devils – increased truck traffic in the Tarkine won’t help. Rhys Allen

Just a week before Christmas, Environment Minister Tony Burke approved Shree Minerals’ mine near Temma in the Tarkine region of north-west Tasmania. Perhaps he hoped the announcement would get lost in the Christmas and New Year “silly season”, because this approval is likely to be extraordinarily controversial: the mine is in an area currently proposed for World Heritage listing and is also in the last remaining stronghold of the Tasmanian devil.

The Tasmanian devil is threatened with extinction by an infectious cancer. Since its first discovery in north-eastern Tasmania in 1996, the cancer has inexorably spread westward, reducing Tasmanian devil populations by at least 80%.

Only the north-west remains undiseased. There are indications that the devil populations in the north-west have slightly different genetic composition from those in the remainder of Tasmania and may perhaps harbour some individuals with genotypes resistant to this lethal disease.

Tony Burke’s press release and his approval of 18 December explicitly recognise the threat that this mine will pose to Tasmanian devils: the developers are required to donate $350,000 to the Save the Tasmanian Devil Program Appeal to compensate for the mine’s unavoidable impact.

Within the limited area of the mine site itself, there will certainly be impacts on wildlife, including devils. More seriously, the ore will need to be trucked out by road for about 150km. Almost all of this distance will be through habitat of undiseased Tasmanian devils.

As scavengers, devils are particularly susceptible to being killed on roads, as they feed on the carcasses of other animals, such as possums or wallabies, which have previously been run over. As anyone who has driven in Tasmania will know, roadkill of Tasmanian Devils is not new. The problem is that its impact on the viability of the species as a whole is much greater now than it has been in the past, given that roadkill is additional to mortality imposed by facial tumour disease. This and other proposed mines will substantially increase total vehicular traffic in the remote north west of Tasmania.

The approval contains several conditions intended to mitigate this threat of roadkill to devils. These include an obligation to report all incidents of roadkill, a requirement that most travel to and from the mine site must occur during daylight hours and reduced speed limits of 50 km/h or less close to the mine site. But most of the distance mine trucks will travel through devil habitat on their way to port will be outside the reduced-speed-limit area.

A penalty of $48,000 will be applied to each Tasmanian devil in excess of two per year killed on the road by mine vehicles. This sounds a strong disincentive in principle, but I wonder what will happen in practice. There will be an even stronger incentive for vehicle operators to simply throw a carcass off the road into the bush rather than admit to killing a devil and incurring this substantial financial penalty.

More generally, this example highlights a problem with Australian environmental regulation. Up to 10 mine developments are currently proposed for the Tarkine area. The impact of each one individually might perhaps be acceptable in terms of increased risk of impacts on Tasmanian devil populations. But the impact of all 10 in aggregate will certainly be much less acceptable.

If mines are evaluated individually, we risk a scenario of “death by 1000 cuts”. The appropriate way to evaluate the risk would be to take all of the proposed developments together and assess whether the joint effect of all can be handled without unacceptable risk to biodiversity conservation.

The fact that this mine development has been approved individually does not give me confidence this approach will be taken.

    Tasmania needs the money from these mines. I suspect the northwest devils would eventually succumb to the disease. If so a mine moratorium simply delays the inevitable. Like the New York flu and humans we're all going to get it eventually. The devils may have to be protected in refuges as with other iconic species. Hopefully some road-smart devils will survive and pass on their survival instincts.

      No John. Tasmania does not 'need' the money from the mines at all. Tasmania - or some people in it - 'wants' the money from the mines, and will continue to survive without it.

      On the other hand, the devils 'need' the mine to stop, otherwise they may not survive.

      I think that makes the choice pretty clear. People should stop being greedy - there is more to life than a bigger flat screen TV you know.

      Well said Mike. As with previous govt industry support in Tassie; such as logging, mining, ship building, casino's etc... these projects gain govt support and benefit a few investors. The average Tasmanian ends up footing the bill and watching their natural heritage disappear. Much of Macquarie Harbour is poisoned from tailings continuing to flow down the King River. You would think the decision makers would have learned from the Gunns fiasco as well.

    The same pattern occurs over and over again. We have an environment minister who makes big announcements suggesting he cares about something - heritage listing for the Kimberley, protection of Tassie forests, strategic assessment for the great barrier reef, the world's biggest marine reserves - and then it turns out they are fig leaves behind which it's business as usual; give the mining industry everything they want; impose conditions that are 'stringent' or 'rigorous' (vomit words!) - and probably…

      It matters to any sensible evaluation of risk. To answer Whyn's question, the ratio is very roughly 1:10 (if figures at http://en.wikipedia.org/wiki/Tasmanian_devil are reliable). Let's assume a way over the top worst case scenario, and say mine traffic will constitute an extra 1% traffic in NW Tas (it's actually orders of magnitude less than that; NW Tas is quiet, but not that quiet). That might make the ratio 1.01:10 (notwithstanding the mine traffic is only during the day, and devils are nocturnal). Even if you got all 10 or whatever mines up, it's then 1.1:10.

      A significant additional threat? Seriously?

      Well Bill, if you want to have a serious discussion about risk, you can't just make up numbers. And if you are going to quote from a source (well - Wikipedia anyway), then you should not just cherry pick the bits you like and discard the bits you don't.

      Why didn't you use this quote, for example:

      "A study in the 1990s on a localised population of devils in a national park in Tasmania recorded a halving of the population after a hitherto gravel access road was upgraded, surfaced with bitumen and widened."

      or this one:

      "The vast majority of deaths occurred in the sealed portion of the road, believed to be due to an increase in speeds"

      or this:

      "Devils have often been victims of roadkill when they are retrieving other roadkill."

      A signifiant addtional threat you ask? The evidence would say yes.

      The reference I gave (chosen mainly because it gave the most accessible summary of the information I utilised) cites the paper you list, among many others. Far from being contradicted by it, it has been used in deriving the estimates I represented. The key is difference in scale, and the word 'localised'.

      I note you didn't quote the part of the abstract which goes on to talk about the effectiveness of countermeasures to minimise devil impacts. These have clearly informed the conditions imposed by regulators e.g. the requirement for mine operators to remove devils from the road even if they didn't hit them.

    Utter bilge. One example: "the ore will need to be trucked out by road for about 150km". Just one minor detail the author left out: almost all of this is ALREADY PUBLIC ROAD. In other words, the ore trucks are only an incremental addition to existing traffic. This is why 'most of the distance mine trucks will travel through devil habitat on their way to port will be outside the reduced-speed-limit area', otherwise you'd have the ludicrous situation of mine trucks crawling along at 50 km/h with traffic banked up behind struggling to overtake at 80 or more.

    And for those as keen as the author to impugn the honesty of truck drivers, there will be frequent inspections and vehicle camera monitoring for compliance with the roadkill conditions.

    Demands that all mining projects in the region be 'assessed together' are also utterly unworkable and unreasonable. The various projects are at very different stages of development and certainty, and are being undertaken by several different companies. It's also condescending and ignorant in the extreme to assume that the various (many) approval processes and regulators for any future mines won't take the impact of existing and simultaneously developing operations into account.

      It's hardly a stunning revelation that company directors are concerned primarily with the interests of their shareholders. Indeed they're obliged to be, by law - no matter what their nationality. That's why we have regulations and conditions. But what Nolan is effectively saying is 'it doesn't matter what conditions you set, we don't trust you to comply with them anyway, because you're miners, and you're foreign.' Not a sustainable starting point for rational evaluation.

      The conditions imposed by Tony Bourke (not Brian, as previously written) are totally inadequate because open cut mining and nature conservation are antithetical; they cannot co-exist. Open cut mining, you may have noticed, leaves little but a hole in the ground and toxic run off.

      The foreignness issue is significant in so far as there is now a global professional bourgeoisie whose commitment is only to its own engrossment. This class knows no national, regional or local interest; it is not accountable to any community or constituency.

      Still, I daresay that the board of directors of Shree Minerals could point to what the East India Company did to India as the source of their inspiration.

      So you will have to forgive us all if we say that we don't actually give a damn about the interests of the mining company, the directors, or their shareholders. We are concerned primarily with the Australian environment and it's native animals.

      No Bill - it does not NEED the money. It wants it. I think you need to look up the definition of 'need' and 'want' in the dictionary.

      And you ask: "Unless you're happy for the rest of the country to fund half a million people to manage the place as a national park."

      First of all, that's a nonsensical statement; no-one is proposing that half a million people become park rangers. But if you are asking if I am happy for my taxes to fund the protection of the Tasmanian bush - you betcha!!!

      Some parts of the country are always going to cost more then they generate in taxes and wealth. That is the way it is now, the way it was in the past, and the way it will be in the future. And we should be making rational decisions about what we are going to protect from development, and be prepared to pay the cost of doing so.

      I am - and I strongly suggest that a lot of others are happy to do so as well.

      Bill, it might also be worth noting that, while mining does generate export revenue, it seems to do so largely at the expense of other Australian industries (note recent downsizing at Bluescope Steel as an illustration) because high commodity prices have, in the end, been jacking up the Oz dollar on international exchanges and thereby making other export industries uncompetitive.

      Frankly, mining starts to look like little more than economic churn.

      And, while I don't inherently object to foreign investment, the evidence of the percentage of profits going overseas from mining versus many other industries is unimpressive. Add in the residual damage that the locals get lumped with remediating and it starts to look as if mining, though profitable in the short term, is not that smart an economic strategy at all.
