Scientists are accidentally helping poachers drive rare species to extinction
If you open Google and start typing “Chinese cave gecko”, the text will auto-populate to “Chinese cave gecko for sale” – just US$150, with delivery. This extremely rare species is just one of an increasingly large number of animals being pushed to extinction in the wild by animal trafficking.
What’s shocking is that the illegal trade in Chinese cave geckoes began so soon after they were first scientifically described in the early 2000s.
It’s not an isolated case; poachers are trawling scientific papers for information on the location and habits of new, rare species.
As we argue in an essay published today in Science, scientists may have to rethink how much information we publicly publish. Ironically, the principles of open access and transparency have led to the creation of detailed online databases that pose a very real threat to endangered species.
We have personally experienced this, in our research on the endangered pink-tailed worm-lizard, a startling creature that resembles a snake. Biologists working in New South Wales are required to provide location data on all species they discover during scientific surveys to an online wildlife atlas.
But after we published our data, the landowners with whom we worked began to find trespassers on their properties. The interlopers had scoured online wildlife atlases. As well as putting animals at risk, this undermines vital long-term relationships between researchers and landowners.
The endangered pink-tailed worm-lizard (Aprasia parapulchella). Author providedThe illegal trade in wildlife has exploded online. Several recently described species have been devastated by poaching almost immediately after appearing in the scientific literature. Particularly at risk are animals with small geographic ranges and specialised habitats, which can be most easily pinpointed.
Poaching isn’t the only problem that is exacerbated by unrestricted access to information on rare and endangered species. Overzealous wildlife enthusiasts are increasingly scanning scientific papers, government and NGO reports, and wildlife atlases to track down unusual species to photograph or handle.
This can seriously disturb the animals, destroy specialised microhabitats, and spread disease. A striking example is the recent outbreak in Europe of a amphibian chytrid fungus, which essentially “eats” the skin of salamanders.
This pathogen was introduced from Asia through wildlife trade, and has already driven some fire salamander populations to extinction.
Fire salamanders have been devastated by diseases introduced through the wildlife trade. Erwin Gruber Rethinking unrestricted accessIn an era when poachers can arm themselves with the latest scientific data, we must urgently rethink whether it is appropriate to put detailed location and habitat information into the public domain.
We argue that before publishing, scientists must ask themselves: will this information aid or harm conservation efforts? Is this species particularly vulnerable to disruption? Is it slow-growing and long-lived? Is it likely to be poached?
Fortunately, this calculus will only be relevant in a few cases. Researchers might feel an intellectual passion for the least lovable subjects, but when it comes to poaching, it is generally only charismatic and attractive animals that have broad commercial appeal.
But in high-risk cases, where economically valuable species lack adequate protection, scientists need to consider censoring themselves to avoid unintentionally contributing to species declines.
Restricting information on rare and endangered species has trade-offs, and might inhibit some conservation efforts. Yet, much useful information can still be openly published without including specific details that could help the nefarious (or misguided) to find a vulnerable species.
There are signs people are beginning to recognise this problem and adapt to it. For example, new species descriptions are now being published without location data or habitat descriptions.
Biologists can take a lesson from other fields such as palaeontology, where important fossil sites are often kept secret to avoid illegal collection. Similar practices are also common in archaeology.
Restricting the open publication of scientifically and socially important information brings its own challenges, and we don’t have all the answers. For example, the dilemma of organising secure databases to collate data on a global scale remains unresolved.
For the most part, the move towards making research freely available is positive; encouraging collaboration and driving new discoveries. But legal or academic requirements to publish location data may be dangerously out of step with real-life risks.
Biologists have a centuries-old tradition of publishing information on rare and endangered species. For much of this history it was an innocuous practice, but as the world changes, scientists must rethink old norms.

Adani Carmichael mine to get six-year holiday on royalties, report says
Activist groups warn that swathes of farmland are at risk since the holiday would cover the Galilee basin and two other undeveloped mining regions
The Adani Carmichael project will reportedly receive a reduced royalty “holiday” offer from the Queensland government under a policy that activists say would subsidise other vast new coal projects that imperil swathes of farmland.
The state treasurer, Curtis Pitt, declined on Friday to confirm a report by the Australian that the Palaszczuk government had settled on a plan to give Adani a pause in royalties for up to six years.

Signed into law by Theodore Roosevelt in 1906, the Antiquities Act has been used by 16 presidents – eight Republicans and eight Democrats – to safeguard millions of acres of exceptional public lands and waters, including outstanding fish and wildlife habitat that provides some of the best hiking, camping, floating, hunting and fishing in the nation.
On 26 April, however, President Donald Trump signed an executive order mandating the review of 27 national monuments nationwide, launching an unprecedented reassessment by the Interior Department.

It’s no secret that human development frequently comes at a cost to other creatures. As our urban footprint expands, native habitat contracts. To compensate for this, most Australian governments require developers to invest in biodiversity offsetting, where habitat is created or protected elsewhere to counterbalance the impact of construction.
Researchers monitored hundreds of nest boxes used to offset habitat loss. Mason Crane, Author providedAlthough biodiversity offsetting is frequently used in Australia – and is becoming increasingly popular around the world – we rarely know whether offsets are actually effective.
That’s why we spent four years monitoring the program designed to offset the environmental losses caused by widening the Hume Highway between Holbrook and Coolac, New South Wales. Our research has found it was completely ineffective.
Map courtesy Google/The Conversation, CC BY-ND Trading trees for boxesThe roadworks required the removal of large, old, hollow-bearing trees, which are critical nesting sites for many animals, including several threatened species. To compensate for these losses, the developer was required to install one nest box for every hollow that was lost – roughly 600 nest boxes were installed.
Wild honeybees occupied many nest boxes. Mason Crane, Author providedMany of the boxes were specifically designed for three threatened species: the squirrel glider, the superb parrot and the brown treecreeper. We monitored the offset for four years to see whether local wildlife used the nest boxes.
We found that the nest boxes were rarely used, with just seven records of the squirrel glider, two of the brown treecreeper, and none of the superb parrot. We often saw all three species in large old tree hollows in the area around the boxes we monitored.
Even more worryingly, almost 10% of the boxes collapsed, were stolen or otherwise rendered ineffective just four years after being installed. Perversely, we found that invasive species such as feral bees and black rats frequently occupied the nest boxes.
The offset clearly failed to deliver the environmental outcomes that were promised. Indeed, researchers have been concerned for some time now that offsetting can be misused and abused.
What can be done?It’s worth noting that research supports using nest boxes as a habitat replacement. However, they may never be effective for species such as the superb parrot. It’s not quite clear why some animals use nest boxes and others don’t, but earlier monitoring projects in the same area found superb parrots consistently avoid them.
Still, concrete steps can – and should – be taken to improve similar offset programs.
First, the one-to-one ratio of nest boxes to tree hollows was inadequate; far more nest boxes needed to be installed to replace the natural hollows that were lost.
There also was no requirement to regularly replace nest boxes as they degrade. It can take a hundred years or more for trees to develop natural hollows suitable for nesting wildlife. To truly offset their removal, thousands of boxes may be required over many decades.
An old hollow-bearing river red gum. Trees like this are vital habitat for many species. Peter Halasz/Wikimedia commons, CC BY-SASecond, nest boxes clearly cannot compensate for the many other key ecological values of large old trees (such as carbon storage, flowering pulses or foraging habitat). This suggests that more effort is needed at the beginning of a development proposal to avoid damaging environmental assets that are extremely difficult to replace – such as large old trees.
Third, where it is simply impossible to protect key features of the environment during infrastructure development, more holistic strategies should be considered. For example, in the case of the woodlands around the Hume Highway, encouraging natural regeneration can help replace old trees.
Tree planting on farms can also make a significant contribution to biodiversity – and some of these may eventually become hollow-bearing trees. A combination of planting new trees and maintaining adequate artificial hollows while those trees mature might be a better approach.
Being accountable for failureWhen an offset program fails, it’s unlikely anyone will be asked to rectify the situation. This is because developers are only required to initiate an offset, and are not responsible for their long-term outcomes.
In the case of the Hume Highway development, the conditions of approval specified that nest boxes were to be installed, but not that they be effective.
Despite the ecological failure of the offset (and over A$200,000 invested), the developer has met these legal obligations.
This distinction between offset compliance and offset effectiveness is a real problem. The Australian government has produced a draft policy of outcomes-based conditions, but using these conditions isn’t mandatory.
The poor results of the Hume Highway offset program are sobering. However, organisations like Roads and Maritime Services are to be commended for ensuring that monitoring was completed and for making the data available for public scrutiny – many agencies do not even do that.
Indeed, through monitoring and evaluation we can often learn more from failures than successes. There are salutary lessons here, critical to ensuring mistakes are not repeated.

Manifesto guide: which party will do the most for cycling?
We compare the manifesto pledges of the Conservatives, Labour, Liberal Democrats, Ukip and the Greens to see who comes top on cycling policy
Amid fevered discussions of Brexit, the NHS and social care, not to mention the suddenly renewed importance of security and tackling terrorism, it might seem a bit niche – almost frivolous – to ask what the party manifestos are saying about cycling.
But I’d argue it’s interesting and worthwhile for a couple of reasons. To begin with, as I’ve endlessly argued on this blog, getting significantly more people on to two wheels can bring enormous benefits to the nation.

Documents suggest that a major spill from the Rover pipeline in Ohio described as 2m gallons of ‘drilling fluids’ might now be more than twice as large
The oil company behind the Dakota Access pipeline is facing intense scrutiny from regulators and activists for a series of recent leaks across the country, including a major spill now believed to be significantly bigger than initially reported.
Documents obtained by the Guardian suggest that a spill from the Rover pipeline that Ohio regulators originally described as 2m gallons might now be more than twice as large. The revelation was included in a legal challenge activists filed on Wednesday to block the natural gas pipeline run by Energy Transfer Partners (ETP), the corporation that operates the controversial Dakota Access pipeline and is now facing numerous government fines and violations.

A new study helps civil engineers account for ongoing climate change in infrastructure design
People who work on building infrastructure understand the risks of climate change. As the Earth warms, new stresses are applied to our buildings, bridges, roads, houses, and other structures. Some of the obvious threats to infrastructure are from extreme weather including heat waves, storms, and intense rainfalls. There are some other less obvious threats, and many of the threats vary by location.
Regardless, the planning for infrastructure relies upon a reasonable estimation of future climate changes. To help quantify such an estimate for the civil engineering community, a recent paper was published by the Institution of Civil Engineering Journal of Forensic Engineering (I was fortunate to be a coauthor). The article was prepared with the collaboration of Dr. Michael Mann from Penn State University and Dr. Lijing Cheng from the Chinese Institute of Atmospheric Physics.
Most Queensland voters oppose taxpayer support for Adani coalmine – poll
59% give thumbs down to state or federal assistance for Carmichael mine as state government faces factional fight over whether to give project a royalties holiday
Queensland voters have given the thumbs down to taxpayer support for the controversial Adani coalmine, with 59% saying they were opposed to state or federal assistance.
A new poll of 1,618 Queenslanders taken by ReachTel indicates 57% of the sample objected to a loan for a rail link between the mine and Abbot point, which is championed by the federal resources minister Matt Canavan.
