GREATER GLIDERS THREATENED WITH EXTINCTION

 Greater Gliders, a nocturnal species and the world’s largest gliding marsupial, weigh up to 1.3 kg and are capable of gliding up to 100m through a forest. Once abundant in eucalypt forests throughout Queensland, NSW and Victoria, the species was federally listed as endangered in July 2022.  

Professor David Lindenmayer, a world-leading expert in forest ecology and biodiversity conservation, said recently, “Forty years ago when my colleagues and I did spotlighting surveys, the southern greater glider was the most common animal we’d see. Now, this amazing species is endangered. In many areas it is hard to find; in others it has been lost altogether.”

Glider populations declined by 80% in the last twenty years as a result of habitat destruction – including forest destruction, bushfires and climate change.  Gliders are amongst the range of species relying on tree hollows which can take over 100 years to develop.  So old growth forest provides the required habitat of large tree hollows where they shelter and breed.

Recently the role of NSW Forest Corporation (Forest Corp) logging in destroying endangered species habitat for Greater Gliders and Koalas has been highlighted with community members reporting numerous breaches of regulations which are supposed to offer some protection for these species.   Breaches in Styx River SF and Sheas Nob SF are amongst the latest reported.

Although the NSW Environment Protection Agency (EPA) has imposed fines on Forest Corp for breaches, environmentalists are concerned that the prosecutions and fines are not enough to bring Forest Corp into line and that effective action is needed from the Environment Minister and Premier to stop the habitat destruction.

One of the community groups campaigning to stop forest destruction is the Blicks River Guardians which last Friday at Billys Creek celebrated 150 days of saving the Greater Gliders in Clouds Creek SF.  The Guardians have identified over 40 gliders to date in bushfire impacted older forests along Billys Creek and the Blicks River in areas scheduled for industrial logging by Forest Corp.

Campaigners like the Guardians are urging people to call for effective Government action to stop the destruction.

POLES APART

A minor furor has just erupted causing North Coast politicians to come out in support of the beleaguered timber industry yet again.

This time it’s over the decision by Essential Energy to replace timber power poles with more fire-resistant synthetic poles.

While the debate rages over the economic loss incurred by the industry versus the never-ending cost of replacing rotting, termite-ridden, and burned-out wooden poles, incurred by consumers, the common-sense solution of putting the lines underground, receives little support.

 The official response to calls for power lines to be relocated underground is that it’s too costly. Energy providers argue that overhead lines are easier to repair, resulting in faster power restoration after outages. This argument appeases consumers but ignores the fact that underground cables are far less prone to the most common cause of disruptions, extreme weather events. It also ignores the fact that the frequency and intensity of those extreme events, including bushfires, are increasing and will continue to increase with climate change.

One factor supporting the underground option is the routine maintenance cost of overhead lines, a figure I couldn't find. However, Essential Energy’s 2022-23 annual report revealed some eye-opening facts. They conducted over 297,000 pole inspections, 67,830 drone flights along 32,000km of powerline, with over 830,000 inspection photos taken, and presumably analysed.

As well, vegetation was removed from almost 187,000 spans of powerline, removing more than 20,000 hazard trees, with a further 9,991 spans inspected for bushfire-related vegetation maintenance.

During that same financial year 7,638 poles were replaced along with more than 15,000 wooden cross-arms.

The cost is clearly phenomenal, but despite all of that, Essential still reported 24,657 unplanned power outages during that period, placing considerable doubt over the cost-effectiveness of that maintenance program.

More than half of the ACT’s power network is underground, much of it planned when the city was founded a hundred years ago. So clearly it can be done.

 No one seriously advocates for the immediate placement of all power underground, but surely it should be considered in the planning for all new developments.

REASONS FOR HOPE

Many people feel  overwhelmed by what is happening on a variety of fronts – in relation to the crises in the natural world, to escalating climate change, to horrific wars, to violence in our communities, to economic hardship and to political stupidity and incompetence.  To some people the possibility that things could or will improve does not seem likely.

Dr Jane Goodall is not one of these people.  She is a world-renowned primatologist, ethologist and environmental advocate who has just conducted a speaking tour on reasons for hope in Australia and New Zealand.

Over many years Dr Goodall, who conducted groundbreaking research on chimpanzees in the Gombi forests in Tanzania, has worked extensively on conservation and animal welfare issues.  In order to encourage others to be involved in seeking positive change, she founded important international organisations – the Jane Goodall Institute (1977) and her youth program Roots and Shoots (1991).

Speaking before her recent tour she said, “Today’s young people – they’re so excited and empowered.  We’re listening to their voices.  That gives us reasons for hope.  I love Australia and New Zealand with its rich biodiversity and proud First Nations heritage.  It will be tremendous to catch up with old friends and meet some of the young leaders making a difference through Roots & Shoots.”

Major issues that she believes need addressing are loss of biodiversity and climate change. Another is the need to raise people out of poverty in countries where abject poverty is driving habitat clearing for reasons like the sale of timber or the need for cropland.

A major reason for hope, she says, is that nature is very resilient and, if it is allowed to recover, or is helped to do so, it will recover over time.  She has seen that in the area surrounding the Gombi Stream National Park in Tanzania.  Her other major hope lies in young people who, when committed to change, work enthusiastically towards it and also have the very important power of influencing their parents and others in the community.

Jane Goodall’s positive message is inspiring.
