Environmental sustainability: a thoroughly Conservative notion

An excellent post by Peter Burnett; hopefully the greater ‘we’ can move these insights into movement toward united action for environmental protection.

Sustainability Bites

In the face of a worsening global crisis, can’t we find some common ground?

By Peter Burnett

‘The Environment’ has been a major public concern for more than fifty years now. Surveys consistently place the environment among the issues of greatest social concern, while numerous scientific reports continue to document a general and ongoing environmental decline. What’s more, the effects of environmental decline are becoming increasingly obvious, not only through intense heat, drought and cyclones, but also as previously unknown phenomena such as multiple coral bleaching events and arctic wildfires.

With all this concern and things
getting worse, you’d expect action, but paradoxically, having gained
considerable momentum in earlier years, environmental policy seems to be moving
more slowly as the problem worsens, like an icebreaker that slows and
eventually becomes stuck as it moves further into the pack ice. Even the Paris
climate agreement of 2015, which looked at the…

“We are the first generation to fully understand climate change and the last generation to be able to do something about it” – global warming reaches 1°C

WMO Secretary-General Petteri Taalas, WMO climate statement: past 4 years warmest on record

Greenhouse gas emission are continuing to increase, temperatures over the past four years have been the warmest on record. The oceans are hotter, higher, and more acidic than ever, and arctic sea-ice keeps on shrinking. Meanwhile,  many parts of the world are being ravaged by tropical storms, floods and heavy rains, heatwaves, droughts, snowstorms, and wildfires, many likely results of climate-change-related changes in global atmospheric and ocean circulation.

Unfortunately, it seems we have now passed a point of no return. The average global temperature has already reached approximately 1°C above pre-industrial levels, and the UN has warned that global attempts to ensure fossil fuel emissions peak by 2020 will most likely fail. Indeed the target will not even be reached by 2030, unless drastic measures are taken.

This is the world we are living in. But it’s not all over yet.

Vehicle tracks are predator highways in intact landscapes: new publication

Our recent paper in Biological Conservation provides an eerie insight into the cryptic impacts of development in otherwise relatively intact landscapes. Aided by a crew of intrepid volunteers, I spent over a year and walked over 560 km, surveying the activity of three mammalian predators — dingoes, cats, and foxes — on and around unsealed vehicle tracks in the largest remaining temperate woodland on earth: the Great Western Woodlands. What I found was startling.

The Great Western Woodlands are largely wild and dominated by natural processes. However, a number of threats to this ecological jewel exist, including a vast network of roads and vehicle tracks supporting an active economy of mineral exploration and extraction. We captured images of our study predators by motion-sensor cameras, and collected scat and print observations as further evidence of their activity, to understand how the presence of roads and tracks affect their activity.

We found that predator activity was between 12 and 261 times greater on roads compared with off-road, making roads (even very simple bush tracks, composed of only two wheel ruts through vegetation) ‘highways’ of predator activity. We also found many other intriguing phenomena, including different patterns in different vegetation types and using different detection methods, and peaks in predator activity at substantial distances away from roads.

With predators having major influences on their prey as well as how ecosystems function in a wider sense, these findings indicate that even apparently minor disturbances can lead to major ecological changes. Furthermore, these trends are likely to apply to many other ecosystems around the world, with global ramifications. At the same time, having this knowledge can also help us to understand how to manage and mitigate these impacts better. 

The paper is available for free till December 29th at: https://authors.elsevier.com/a/1Y1Mk1R~eAsRA.

So the next time someone you walk down a simple road through the bush… consider what else has walked that way too, and what it might have preyed upon along the way.

Thank you to my co-authors, who were also my PhD supervisors, for their incredible inspiration and support for this research, and the incredible field volunteers I recruited. A big thank you also to the funding agencies and organisations that helped make this work possible – they are detailed in the ‘acknowledgements’ section of the paper.

What about the ugly things?

Addressing bias in conservation efforts: through song!

A big thank you to the Wilderness Society of Australia for this fabulous clip. And thank you to all the ugly (and not so ugly) things that make our planet tick! Rock it out!

The three most dangerous narratives in conservation

In the blog ‘Thinking Like a Human‘:

An excellent piece about the stories we live and work by… and thinking carefully about their implications. Thanks Chris Sandbrook!

Thinking like a human

Emery Roe, an American policy scholar, first developed the idea that ‘narratives’ – stories about the world and how it works – are used in policy making processes to cut through complexity and justify a particular course of action. We are a storytelling species, and people find it easy to understand and get behind a compelling story with strong internal logic and a beginning, middle and end. Once a narrative has taken hold they can be very difficult to shake off, at least until an even more compelling ‘counter-narrative’ arrives on the scene. A classic example from resource governance is the ‘resources will be over-exploited unless they are in private ownership’ narrative, based on Garrett Hardin’s 1968 Tragedy of the Common’s article. It took decades of careful scholarship, and ultimately a nobel prize for Elinor Ostrom, to demonstrate that this narrative was compelling, influential, and wrong.

There are numerous narratives…

Planning for population persistence in the face of ecological traps

­My tweetentation (presentation via tweets) for the Inaugural @ARC_CEED Centre of Excellence for Environmental Decisions Twitter Conference #CEEDTC2018. To view on Twitter click here. @kerenraiter

Abstract: We’re using emerging information on species distribution, dispersal & genetic variation combined with insights into varying effects of different land management – incl. ecological traps, to provide cross-tenure decision support for ensuring endangered lizard persistence.


1/6: Integrating population viability & complex threatening processes such as ecological traps, into systematic conservation planning can improve the effectiveness of conservation plans, and encourage land manager engagement : Dror Hawlena Risk Management Lab.


overview wordle 1



2/6 We explore the challenges of conservation planning in the face of complex realities for critically endangered Israeli fringe-fingered lizards: we modelled species distribution and show devastating historical habitat loss followed by threats of a new sort…


2. SDM



3/ ‘Desert tree’ projects create ecological traps: habitats that lizards quickly colonize, but where the lizards are quickly predated due to trees providing perches for predatory birds. A relatively small area of ‘trap’ can drain lizards from the surrounding landscape

3. ecological trap


4/6 We are developing simulations to model ecological trap effects on population dynamics and advise land managers how to avoid driving the lizards to extinction. Trap effects vary between species. Collaborators sought!
4. Trap simulation


5/6 Eco-trap simulations will be integrated into landscape population viability analyses informed by genetic analysis of dispersal, geneflow, and population structure, as well as emerging information on grazing, defense-force, agricultural and climate change impacts.


5. My plan



6/6 Integrating these factors will extend the theory and practice of conservation planning; provide cross-tenure decision support for interested stakeholders to help avoid extinction and maximize endangered lizard (& sub-population) persistence. Collaborators invited.
