The Gully’s urban periphery – discovering a female Blotched Blue-tongue Lizard

Friday, February 28th, 2025

Within just a minute’s walk from The Habitat Advocate base we happened upon some wonderful local wildlife. 

It was a native Blotched Blue Tongue Lizard in this case (scientific species name Tiliqua nigrolutea).   It was 10th February 2025 (summer) in the late hot afternoon around 6:30pm AEDT, so the sun was still up in the western sky; this given sunsets in late summer at this time of year are as late as 8 pm, some two hours hence.   So, this happenstance timing made sense, but a rare sighting these days.

 

This particular lizard was not easy to then photograph due to it subsequently retreating from the footpath (after we went back for our camera) and retreating into the camouflage cover of the grassy verge behind for safety.

 

Upon our initial sighting, this lizard had been laying in the middle of the footpath sunning itself – being a cold-blooded lizard (‘ectothermically’ that is; not the human malice variety).

This one we think is female – telling from the comparatively small head size and its thicker tail root.  It was not a native Shingleback Lizard (scientific species name Tiliqua rugosa) since such species has a stubbed tail land prefers the habitat plains inland from the Great Dividing Range, and are not found in the Blue Mountains region, whereas Blue Tongues are. 

The location was on The Gully’s urban periphery, yet wholly environmentally within the broader Gully Water Subcatchment, where The Habitat Advocate is based.  So nice to see wildlife in one’s neighbourhood – we share local wildlife’s neighbourhood.  

We provide hyperlinks below to further information and clearer images about this lizard species.

Anyway, it was a pleasurably welcomed and encouraging sighting.

Such sightings however are increasingly rare around these parts these days due to Council’s habitat destruction – pretty much since Council has existed since its origins in Katoomba in 1890, then in 1947 re-branding itself Blue Mountains City Council from being a two adjacent regional municipality/shire councils.   Then from November 2000 after the Blue Mountains region was declared an international World Heritage Area, this local Blue Mountains Council has bizarrely extolled its contradictory perceived virtues of being a city within a World Heritage Area – what espousing urban sprawl development and high-rises amongst Eucalyptus habitat?

We bought our house in 2000, which had there since the 1920’s.  So, we did not build into bush, but rather it was long existing ‘in-town’, and so technically we just recycled and renovated it.  It had had only lawn back and front, but since 2001 we have created an onsite forest and restored much local habitat on site, So, no more grass and we then gave away our lawn mower!

One also recalls that on 13th February back in 2017 around 5:30 pm during a 47o Celsius unseasonal heatwave weather event across New South Wales, observing a large native Eastern Brown Snake (scientific species Pseudonaja textilis) of almost 2 metres in length scurrying across the scorching road surface of our street into the cooler shade of our forested front garden.  Well, we chose not to garden or water there for a week afterwards and warned our neighbours.  However, we immediately reported this snake sighting to the volunteer-based Wildlife Rescue Service (WIRES) for safety guidance and we spoke to one of their trained snake catchers who gave us helpful and reassuring advice over the phone.

Also, when we first moved in where we are, one had to contend with a native Blue Mountains Funnel Web Spider (scientific name Hadronyche versuta) ground nest in our then unkempt backyard, also unfortunately the native Brown Broadfooted Marsupial Mouse (scientific name is Antechinus stuartii) family over the back fence that we observed, eventually sadly perished.

But it beats living in increasing sprawling concreted, treeless sterile Sydney human megalopolis.

The Pilliga Forests

.

The Pilliga‘, also traditionally known as ‘The Pilliga Scrub‘ is a vast western woodland – the largest continuous remnant of semi-arid woodland in temperate New South Wales, Australia.  The Pilliga comprises the largest remaining area of native forest west of the Great Dividing Range, covering about 500,000 hectares between the Namoi River in the North and Warrumbungle Ranges in the South.  The Pilliga is part of the Brigalow Belt South bioregion. Australian land mass is divided into 85 bioregions. Each bioregion is a large geographically distinct area of similar climate, geology, landform, vegetation and animal communities. [Read More]

The Pilliga is characterised by native white cypress and iron bark forests, broom bush plains, vivid spring flowers and abundant fauna.  The forest contains at least 300 native animal species, with at least 22 endangered animal species including such favorites as the Glossy Black-Cockatoo, Squirrel Glider, Koala, Pilliga Mouse (Pseudomys pilligaensis) and Rufous Bettong, and at least 900 plant species including species now widely grown in cultivation as well as many threatened plant species. The forest spans about 3,000 square kilometres of land. Some towns that surround the forest include Narrabri, Pilliga, Gwabegar, Baradine, Coonabarabran, Boggabri and Baan Baa.  Some areas of the forest, particularly in the Western Pilliga, are completely dominated by “cypress pine” (Callitris spp.), however there are a vast number of distinct plant communities in the forest, some of which do not include Callitris pine. Another dominant sub-canopy genus are the Casuarinas, while Eucalypts dominate the canopy throughout the forest. Much of the area is State Forest under the management of the New South Wales Government, which effectively means that it is unprotected.

The name ‘Pilliga’ (or ‘Billarga‘) is an Aboriginal word meaning swamp oak (Casuarina trees).  The name was borrowed back in the mid 1800’s as the name of one of the original grazing runs, near where the town of Pilliga now stands. [This theory is contracted by Les Murray in his Forward in Eric Rolls‘ seminal 1981 book ‘A Million Wild Acres‘, who accounts at page iv…”the Pilliga (from Kamilaroi peelaka, a spearhead”).

The geology of the area is dominated by the Pilliga Sandstone, a coarse red/yellow Jurassic sandstone containing about 75% quartz, 15% plagioclase and 10% iron oxide,[2] although local variations in soil type do occur. Sandstone outcrops with basalt-capped ridges are common in the south, while the Pilliga outwash areas to the north and west are dominated by alluvial sediment from the sandy, flooding creeks.

.

There is a vast network of roads throughout the scrub, many of which are former forestry roads. The forest once supported a large forestry industry in the surrounding towns (harvesting mostly cypress pine and ironbarks) however this has been greatly scaled back since 2005 when much of the forest was set aside for environmental conservation by the NSW government.

According to the Narrabri Shire Visitor Information Centre, the Pilliga Forest… ‘is one of the largest native cypress forests in Australia and hosts an abundance of wildlife including koalas,  kangaroos, possums, echidnas, goannas, emus and its very own species of mouse, the Pilliga Mouse.  The area is renowned for its glorious wildflowers which can be found in the Forest year round, with particularly impressive displays in Spring. The Baradine Community has developed three wildflower routes through the Forest. The “Wildflowers of Baradine and the Pilliga’.

‘The Pilliga’..after rain

.


 

‘Prolific rain on the northwest plains of New South Wales

quickly results in a swelling of rivers and creeks,

followed by a profusion of growth and renewal.

.
Many centimetres of very welcome rain covered the black soil grazing pastures and agricultural properties

surrounding the village of Baradine over the first weekend of February, 2010.

We were there to witness this amazing natural event.
Sheets of water rapidly cover the vast plains,

draining into gullies and creeks, and filling rivers.

Many outlying unsealed roads become impassable,

and the town is temporarily isolated.

But life goes on with relative normality,

albeit with joyous appreciation of the blessings the downpour will bring.’

The Pilliga’s history of colonial exploitation

.

‘Following many thousands of years of Aboriginal occupation, European settlers started arriving around the early 1830’s. These settlers established grazing runs throughout the forests, which then comprised a few well-scattered large trees over a grassy understorey. Aboriginal burning and grazing by Kangaroo Rats had kept the forest floor clear of regeneration until that time.

The introduction of cattle and sheep resulted in significant ecological changes. The soils deteriorated and the mix (and grazing quality) of the native grasses changed. The Kangaroo rats were displaced. The 1970’s and 1880’s produced a prolonged drought that saw most of the grazing runs abandoned. Then, during the late 1880’s and early 1890’s, there was a succession of good seasons and, in the absence of grazing pressure and regular burning; massive regeneration of native cypress and eucalyptus took place across much of the Pilliga.

The spread of rabbits to the area in the early 1900’s prevented any further regeneration events in the Pilliga until the introduction of myxomatosis in the 1950’s. With the demise of the Rabbit, a new pulse of young cypress and eucalypt seedlings was able to get up and away.

The cypress regeneration from the late 1800’s forms the basis of the timber industry operating from the Pilliga today. The 1950’s and subsequent growth is being managed to provide a sustainable supply of timber to industry for generations to come. In 1999, there were over 150 jobs dependant on the timber resources of the Pilliga and the industry provides the backbone of many small communities on the fringe of the Pilliga.

Between the 1920’s and mid 1990’s, over 5 million railway sleepers were cut from ironbark grown in the Pilliga.

Ironbark is still used to produce fence posts and drops for electric fencing systems, where the non-conductivity of its heartwood provides a unique advantage.’   [Source:  ^http://narrabri.net/Document1.aspx?id=1872]

The endemic ‘Pilliga Mouse’

Endemic‘ means found naturally nowhere else on the planet.

The Pilliga Mouse (Pseudomys pilligaensis ) is a small native murid rodent found in the Pilliga Forests ecosystem.  It is listed as Vulnerable in Australia and is endemic to the Pilliga Forests of New South Wales.

The Pilliga Mouse is very sparsely distributed and appears to prefer moist gullies, areas dominated by extensive coverage of low grasses and sedges, broombush and areas containing an understorey of kurricabah (Acacia burrowii) with a bloodwood (Corymbia trachyphloia) overstorey. It is nocturnal and appears to live in burrows.

Its main threats are from logging operations that destroy the understorey particularly broombush, inappropriate fire regimes (broadscale and frequent bushfire management), predation by ferals (foxes, cats and wild pigs/boars)

The Pilliga… now threatened by Mining

‘Eastern Star Gas coal seam expansion in Pilliga under federal investigation’

(Article on ABC Rural, 20110721, ^http://www.abc.net.au/rural/news/content/201107/s3274633.htm]

.

The Federal Government is investigating whether Eastern Star Gas is in breach of the Environment Protection Biodiversity Conseration Act at its coal seam gas project in NSW’s Pilliga forest.

The project is expected to result in the first large-scale coal seam gas operation in NSW.  The Pilliga forest is the largest remaining temperate woodland in eastern Australia.

Chief Executive Officer of the National Conservation Council, Pepe Clark is calling on Santos, which owns Eastern Star Gas, to either desist or defer work until they have Federal approval.

‘Pilliga coal seam gas developments breach Federal environmental law: report’

(Article by Nature Conservation Council of NSW, 20110719, ^http://www.nccnsw.org.au/media/pilliga-coal-seam-gas-developments-breach-federal-environmental-law-report)

.

‘Eastern Star Gas has conducted coal seam gas exploration and production activities in the Pilliga forest without seeking federal assessment on matters of national environmental significance, according to a report by the Northern Inland Council for the Environment, The Wilderness Society and the Nature Conservation Council of NSW.

The report, Under the Radar, was released today following the recent purchase of Eastern Star Gas by one of Australia’s largest domestic gas producers, Santos.

“Eastern Star Gas has undertaken extensive coal seam gas exploration and production without seeking federal approval. This is likely to have damaged the habitat of iconic threatened species such as the Pilliga Mouse and the Regent Honeyeater,” said Warrick Jordan, Campaign Manager at the Wilderness Society Newcastle.

“Santos is taking on the most environmentally destructive and contentious gas project in NSW. As the new owner, Santos should look carefully at the damaging impacts of this proposal and immediately desist or refer all existing operations in the Pilliga for proper assessment.

“We are asking Tony Burke to immediately ‘call-in’ all existing Eastern Star Gas operations in the Pilliga under federal environment laws. Eastern Star should not be able to get away with destroying our natural heritage,” he said.

The Under the Radar report found coal seam gas operations in the Pilliga have cleared more than 150ha and fragmented 1,700ha of bushland, drilled 92 coal seam gas wells, constructed 56.6km of pipelines, and operated 35 production wells without seeking approval under the Federal EPBC Act. These activities have occurred in habitat for federally-listed threatened species, such as the South-Eastern Long-eared Bat.

“Under Commonwealth legislation, any potential impacts on nationally-threatened species must be referred to the Environment Department for approval. Eastern Star Gas has been flying under the radar to avoid this process in the Pilliga,” said Pepe Clarke, CEO of the Nature Conservation Council of NSW.

“Eastern Star has recently applied for Commonwealth approval for a large new coal seam gas field in the same area of the Pilliga as existing operations. If these future operations trigger federal environment laws, then so do the existing operations and Santos should immediately cease those operations and be refer them to the Federal Government”,” he said.

“The question remains, will Santos continue Eastern Star’s reckless attempts to turn the iconic Pilliga Forest into an industrial coal seam gas field? If Santos can’t be trusted to abide by environmental laws now, they cannot be trusted to manage the environmental impacts of NSW’ biggest coal seam gas development,” said Carmel Flint, of the Northern Inland Council for the Environment.

Under the Radar report summary

The Federal Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) makes it illegal to undertake an activity that has, or is likely to have, a significant impact on matters of national environment significance. These prohibitions are set down in Part 3 of the EPBC Act 1999, in s18 and s20 respectively.

There are at least 24 matters of national environmental significance, as defined by the EPBC Act, which occur within the Pilliga Forest section of the Eastern Star Gas Petroleum Exploration Licence 238 and Petroleum Assessment Lease 2. These include known, likely, and potential habitat for 15 nationally threatened species (4 endangered, 11 vulnerable), and known or potential habitat for 9 migratory birds listed under international conventions.

Environment groups have conducted a detailed assessment of the likely impacts of current coal seam gas activities in the Pilliga Forest on matters of national environmental significance, by applying the Guidelines for Significant Impact set down by the Department of Sustainability, Environment, Water, Population and Communities (SEWPaC). These are the same guidelines that should have been applied by Eastern Star Gas to assess the impacts of the activities.

The following coal seam gas activities have been undertaken in PEL 238 and PAL2:

1. The drilling and on-going management of more than 92 coal seam gas bores and coreholes

2. The conduct of 482km of seismic surveys

3. The construction and management of 56.6km of gas and water gathering pipelines

4. The development and management of five production fields, encompassing 35 production bores

5. The construction and management of a gas-fired power station at Wilga Park, including an upgrade of the station from 10MW to 40MW

6. The construction and operation of 1 reverse osmosis unit

7. The construction and management of 13 major water treatment dams/impoundments and numerous drill ponds

8. The discharge of treated produced water into the Bohena Ck, part of the Murray-Darling Basin.

9. The bull-dozing of numerous roads and tracks to facilitate the construction and operation of works listed above.

None of these activities, nor the whole action combined, has ever been referred to the Federal Government for consideration of the likely impacts on federally-listed species under the EPBC Act 1999. There is no Federal approval in place for the action.

The environmental impacts of these activities include: direct destruction of at least 150ha of native vegetation that is habitat for federally-listed species; heavy fragmentation of an area of 1,700 ha of native vegetation leading to the spread of invasive species; creation of artificial watering points at more than 13 different locations representing a risk to wildlife; introducing numerous sources of pollution through the use of chemicals and the handling and disposal of produced water; direct alteration of the ecology of a creek system for up to 22km; increased fire ignition sources and introduction of a flammable gas into an already fire prone environment; an overall disturbance footprint across 44,700ha of bushland.

Applying the Guidelines for Significant Impact, the report concludes that the impacts on federally-listed species are likely to be significant because of the intensity at which they have occurred, as well as:

  • The extraordinary national and international conservation significance of the environment in which it is occurring;
  • The sensitivity of the ecosystem given the scale of extinctions that have already occurred in the mammal fauna and the scale of decline now evident in the bird fauna;
  • The substantial geographic area affected;
  • The high cumulative impact in the context of other threats (other mining and gas developments, background clearing rates, climate change, invasive species, logging, and high intensity and frequent fires);
  • The low level of confidence with which the impacts are understood; and
  • the context in which it occurs of a heavily cleared and highly fragmented landscape with very low levels of reservation.
  • The measures put in place by Eastern Star Gas to avoid or mitigate impacts are inadequate to prevent such impacts, and their effectiveness is uncertain and not scientifically established.

‘Farmers see threat in $900m Santos buyout’

(Article by Ben Cubby and Brian Robins, in Sydney Morning Herald, 20110719, ^http://www.smh.com.au/environment/farmers-see-threat-in-900m-santos-buyout-20110718-1hlq7.html)

.

‘A GAS exploration company chaired by the former deputy prime minister John Anderson will be bought out for $900 million, in a move expected to pave the way for the first large-scale coal seam gas drilling operation in NSW.

The resources giant Santos will buy Mr Anderson’s Eastern Star Gas, which has plans to drill more than 500 gas wells in the Pilliga scrub, near Narrabri, the largest surviving remnant of temperate woodland in eastern Australia.

The plan has already sparked fierce resistance from some farmers, who have said they will lock their gates rather than allow drilling rigs on their grazing land. Many are concerned that the controversial fracking technique, which can lead to groundwater contamination, will be used.

Santos said it recognised the objections people had to coal seam gas drilling, and would campaign to win public support.

”We are confident these issues can be addressed,” said the chief executive, David Knox. ”We’re going to set the right pace and bring [the community] along, as we prove things up … We recognise the criticality of working with local communities.”

Last month Santos launched a television advertising campaign, saying that coal seam gas was ”a fuel for the future” and that the company had previously forged good relationships with rural land-holders.

Mr Knox said the federal government’s introduction of a carbon price would increase demand for gas instead of coal, which generally had higher greenhouse gas emissions.

The acquisition will make Santos the state’s biggest holder of coal seam gasfields.

Opponents say the construction of hundreds of wells, and a network of roads linking them, would industrialise the landscape. ”What’s being allowed here is an uncontrolled experiment on the Australian environment,” said Drew Hutton, a campaigner with the anti-coal seam gas group Lock the Gate Alliance.

Initial surveys prepared for Eastern Star indicate the area is home to many threatened animal and plant species, including the Pilliga mouse, black-striped wallaby, glossy black cockatoo, painted honeyeater and barking owl.

From the beginning of June the Moree Plains Shire Council has placed a 60-day moratorium on seismic surveys, drilling or exploration for coal seam gas, to allow the council and community time to study the implications of proposals.

A report produced by the Wilderness Society said the project was of national significance and should be independently assessed by the federal Environment Minister, Tony Burke.

“The Pilliga project, if it proceeds, will have a devastating impact on the environment,” said a Wilderness Society campaigner, Warrick Jordan.

”It will clear 2410 hectares of valuable bushland across the eastern Pilliga, including in a state conservation area, pose risks to the Great Artesian Basin, produce massive amounts of saline water, and the associated pipelines and wells will impact surrounding agricultural areas.”

The Nature Conservation Council of NSW also said that work already done on the site meant it should be referred to the federal government.

Tony Pickard, a farmer whose land falls within the proposed gas well area, said the first he had heard of the proposal was on a government website that showed dots on his land representing gas wells. Mr Pickard has vowed not to allow drilling on his land.

A NSW Greens MP, Jeremy Buckingham, is travelling through the state speaking to people who oppose coal seam gas extraction.

”To have an energy giant like Santos move in and take over means that the project is much more likely to go ahead,” Mr Buckingham said.

‘Under the Radar – new report lifts the lid on Eastern Star Gas operations’

– Article by The Wilderness Society, [Source: ^http://www.wilderness.org.au/campaigns/coal-seam-gas/under-the-radar-new-report-lifts-the-lid-on-eastern-star-gas-operations] .

‘Eastern Star Gas has been trashing parts of the Pilliga since 2004, avoiding environmental laws in the process. A new report by the Wilderness Society, the Northern Inland Council for the Environment, and the Nature Conservation Council has exposed this scandal.

The Pilliga Forest is home to a host of threatened species, including the Pilliga Mouse and the Regent Honeyeater. Many of these species are listed under the federal Environmental Protection and Biodiversity Conservation Act.

When a company wants to develop a project on a site with nationally listed threatened species, they are required by law to refer the project to the federal environment department.

Eastern Star Gas has been exploring for and producing coal seam gas in the Pilliga Forest since 2004. This has resulted, amongst other actions, in the clearing of 150 hectares of forest, fragmentation of a further 1700 hectares, and the dumping of waste water into creeks.

The Under the Radar (1.35MB – pdf) report concludes that Eastern Star Gas has impacted threatened species habitat, and should have sought federal environmental assessment for its operations. All current and proposed activities should be suspended, and assessed by the Commonwealth Environment Department.

Eastern Star Gas, after ignoring environmental legislation, now wants to build the biggest coal seam gas project in NSW in the Pilliga. They promote this destructive project as environmentally friendly and well managed.

Eastern Star has been exposed as a company that will get away with what it can if it thinks no-one is looking.

Well, now we are watching, and we’ll be ensuring, with your help, that the unique Pilliga Forest won’t become an industrial wasteland.’

‘A national treasure or an industrial wasteland?’

– Article by Carmel Flint in the Colong Bulletin, No. 241, July 2011, pp.1-2,  reproduced with premission of The Colong Foundation for Wilderness, Inc.
.

Coal seam gas has recently emerged as a massive threat to the future of the Pilliga Forest, in north-west NSW.  The Pilliga is located between Narrabri and Coonabarabran, and covers an extraordinary 500,000 hectares of intact and contiguous bushland.

The Bibblewindi water pollution ponds are one of ten constructed during the Pilliga ‘exploration’ phase.
So far there are 1,100 well heads planned for gas extraction just in the eastern quarter of the Pilliga alone.

One tends to run out of superlatives very quickly when it comes to the conservation significance of the Pilliga.

It is the largest temperate woodland left in eastern Australia and the southern recharge area for the Great Artesian Basin. It’s surface waters flow into the rivers of the Murray-Darling Basin. It is the single most important biodiversity refuge area remaining in the NSW Wheat-Sheep Belt.

The Pilliga is home to more  than 25 threatened or migratory species that are listed under federal laws and at least 48 threatened species under NSW law. It includes the only known population of the endemic Pilliga Mouse, the largest Koala population in western NSW and the only known Black-striped Wallaby population in western NSW. It represents the national stronghold for populations of the Barking Owl and the Southeastern Long-eared Bat within eastern Australia.

It is an internationally recognised Important Bird Area, with particular significance for the Painted Honeyeater and Diamond Firetail. It is also recognised as an important part of the East Australian Bird Migration System, and is located in the Brigalow Belt South bioregion which is one of only 15 biodiversity hotspots recognised by the Federal Government across the nation. It is mostly public land, either State Forest, State Conservation Area or National Park, and it has recognised wilderness values.
Coal seam gas companies have been conducting exploration in the Pilliga for about 10 years now, and they have already done considerable damage. Under the guise of exploration, they have to date drilled 92 coal seam gas wells, constructed 46.2km of pipelines, conducted 394.2km of seismic surveys, constructed 1 gas compression station and 1 reverse osmosis unit, developed five pilot production fields encompassing 35 boreholes, produced and delivered gas to a local power station, constructed
10 major water treatment dams/impoundments, discharged produced water into a local creek system and bulldozed numerous roads and tracks.  This, however, is just the tip of the iceberg. In April this year Eastern Star Gas applied to the Federal Government for
an environmental approval to move to full production in the Pilliga Forest.

They want to put in 1,100 wellheads and 1,000km of pipelines across the eastern section of the Pilliga, clearing at least 2,410 hectares and fragmenting 85,000 hectares.

.

Associated with this proposal are two pipelines – one to a proposed gas-fired power station at Wellington and another to a proposed new LNG export facility at Newcastle. By incorporating the first ever major LNG export facility, this Pilliga proposal will effectively open up the whole state to a massive expansion in coal seam gas.  And, if that is not enough,  it is very clear that this is only  the beginning of the project.  Having reviewed the data on  coal seam gas potential across the companies full exploration licence (PEL238) we estimate that they will ultimately drill 7,100 boreholes, develop 7,000km of pipeline and clear more than 8,000 hectares of land across the Pilliga Forest and farmlands to the north.
Coal seam gas will destroy, fragment and degrade the integrity of this natural treasure. It will transform a thriving, living ecosystem into a heavy industrial zone with massive impacts on fauna and flora. It will dramatically increase fire risk and forever
change the nature of this wildflower wonderland.

.

If you don’t accept such an appalling transformation, then please act now to do something about it.

The ensuing explosion has caused extensive and heated debate ever since amongst historians, ecologists, environmentalists, poets and writers. Now reprinted in a commemorative 30th Anniversary Edition for a new generation of readers and against the backdrop of renewed and urgent concern about climate change, it includes Tom Griffiths’ seminal essay, The Writing of A Million Wild Acres, and a foreword by Les Murray drawn from his work Eric Rolls and the Golden Disobedience.

Here is a contentious story of men and their passion for land; of occupation and settlement; of destruction and growth. By following the tracks of these pioneers who crossed the Blue Mountains into northern New South Wales, Eric Rolls – poet, farmer and self-taught naturalist – has written the history of European settlement in Australia. He evokes the ruthlessness and determination of the first settlers who worked the land — a land they knew little about.

Rolls has re-written the history of settlement and destroyed the argument that Australia’s present dense eucalypt forests are the remnants of 200 years of energetic clearing.

Neither education nor social advantage decided the success of the first settlers, or those squatters, selectors, stockmen and timber getters who helped grow the Pilliga forest. Few men were more violent than John Macarthur, few rogues more vigorous than William Cox, few statesmen more self-seeking than William Wentworth.

Rolls’ environment teems with wildlife, with plants and trees, with feral pigs; with the marvellous interaction of insects and plants, rare animals and birds. The lovely tangle which is the modern forest comes to life as Rolls reflects on soils, living conditions, breeding and ecology.

Winner of the prestigious Age Book of the Year Award, A Million Wild Acres is also an important account of the long-term effect man – both black and white – has had upon the forest.’

The story of the Pilliga forest is one of advance, disappointment and retreat by pastoralists and then by small farmers“. [Les Murray]

May Santos and its Eastern Star Gas venture follow suit and show The Pilliga the respect it so long deserves.

‘Save Pilliga – NSW’s Largest Temperate Woodland’

— by Cate Faehrmann May 25, 2011

Introduction

Eastern Star Gas has applied for approval under both state and federal regulations to develop a massive coal seam gas field of around 550 gas wells in the State Forests of The Pilliga. Commonly known as the ‘Pilliga Scrub’, this unique woodland is near Narrabri in northern NSW. The gas project is set to clear over 2,400 hectares of native vegetation and will forever change the landscape of the Pilliga.

The Pilliga Scrub is a highly significant area in terms of the state’s biodiversity. It is known to be the largest continuous remnant of semi-arid woodland in temperate New South Wales and contains many threatened animal and plant species such as the Pilliga Mouse, Black-striped Wallaby and South-eastern Long-eared Bat.

Email the Minister now and ask him to protect the Pilliga Scrub from coal seam gas.

Black-striped Wallaby, a mostly nocturnal animal under threat from land clearing, and now, coal seam gas.

The gas field and the related infrastructure proposals (including two major regional pipelines) have been determined to be ‘controlled actions’ under the Environment Protection and Biodiversity Conservation (EPBC) Act. This means they will require the approval of Minister Tony Burke and the Federal Department of Environment. There is also a proposal from Eastern Star Gas being referred for a LNG export processing facility at Kooragang Island at Newcastle.

At the NSW Government level, the projects are being assessed by the Department of Planning under Part3A. The Director General’s Requirements (DGRs) for the environmental assessments were issued in December 2010, but this was not made public until after the recent state election. You can view them here.

This is the biggest coal seam gas field ever proposed in NSW and the first ever LNG export facility in the state. However, it looks to be just the beginning. Eastern Star Gas, headed by former Nationals Leader and Deputy Prime Minister John Anderson, has not revealed their full plans for the area. Coal seams extend underneath almost the entire Pilliga Scrub, and this initial proposal covers 85,000ha of a 500,000ha vegetation remnant. Extrapolating these figures, 550 wells now could mean as many as 3,000 wells in the future. You can read more about the EPBC referrals for the Narrabri Gas Field here at the Federal Environment Department’s website.

The four project components

  1. Development of a major coal seam gas field in the Pilliga Scrub
  2. A pipeline from Narrabri to Wellington (via Coolah)
  3. A pipeline from Coolah to Newcastle
  4. An LNG export facility at Kooragang Island at Newcastle

Existing activities

Eastern Star Gas Limited (ESG) is the operator of the Narrabri CSG Joint Venture (NJV). Some 35% of the CSG interest in PEL 238 is strata titled to Santos. The Chairman of ESG is John Anderson, former National Party politician. The Narrabri Coal Seam Gas Project is being developed by the NJV.
ESG developed the Wilga Park Power Station in 2004, and supplied it with gas from the Coonarah Gas Field on private land to the north of the Pilliga.
In 2006, a number of closely spaced well production pilots were developed in the Bohena and Bibblewindi fields in the Pilliga Scrub. In 2008, approval was granted for a gas pipeline from the pilot wells in the Pilliga to the Wilga Park Power Station and the expansion of the power station. The expected supply of gas from the Coonarah Gas fields did not eventuate, and the station has been utilising production gas from the pilot wells.  The NJV currently has an MOU with ERM Power for the provision of gas to a new gas fired power station at Wellington over a 20 year period commencing in 2013.

Gas field development

The proposed gas field development area covers approximately 85,000 ha and includes Pilliga East State Forest, Bibblewindi State Forest, Jacks Creek State Forest, and Pilliga East State Conservation Area, plus some small areas of Crown Land and private land. The project aims to produce, process, compress and transport CSG from within Petroleum Exploration Licence 238, Petroleum Production Lease 3 and Petroleum Assessment Lease 2.

The project proposal includes the following:

  • 550 production well sets, initially, on a 500m spacing
  • 1,000 km of gas and water gathering systems (ie pipelines)
  • access tracks (through the Pilliga Forests)
  • a co-located gas processing and compression plant
  • a centralised water management facility
  • Ancillary infrastructure such as offices and workshops.

Impacts

The gas production will clear at least 2,410 hectares of native vegetation!

The area that is being targeted includes:

  • A rich variety of heritage sites, including a rock shelter, burials, a grinding groove, scarred trees, open sites, stone artefact scatters and isolated finds.
  • An Internationally recognised Important Bird Area.
  • Known or likely habitat for 25 nationally listed threatened species and five nationally listed Endangered Ecological Communities.
  • Known or likely habitat for 48 state-listed threatened species and five state-listed Endangered Ecological Communities including:
  • Pilliga Mouse – known only from the Pilliga Scrub, this nationally vulnerable species has a total distribution of only 100,000 hectares. It will be severely impacted by the direct habitat loss, increased predation, and fragmentation leading to impacts on dispersal.
  • Black-striped Wallaby – endangered in NSW, the northern Pilliga is the only known location of this species in western NSW. Requiring dense vegetation, it is extremely vulnerable to clearing, fragmentation and increased predation.
  • Malleefowl – considered endangered in NSW and nationally vulnerable, has been recorded previously in eastern Pilliga. It is highly vulnerable to increased predation and fire.
  • South-eastern Long-eared Bat – the Pilliga Scrub is recognised as the likely national stronghold for this vulnerable species (NSW and Federal). It prefers large, intact stands of native vegetation, and is at risk of fragmentation, loss of hollow trees, and uncovered saline ponds. Numerous other threatened bat species face similar risks from the proposal.
  • Glossy Black Cockatoo – a very significant western population of the Glossy Black Cockatoo occurs in the Pilliga Scrub.
  • Squirrel Glider, Koala and Eastern Pygmy Possum – which are all likely to be severely impacted by the direct habitat loss, fragmentation (and particularly its impacts on mobility and dispersal), and increased predation.
  • Grey-crowned Babbler, Diamond Firetail, Hooded Robin, Speckled Warbler – and numerous other declining woodland birds for which the Pilliga represents a major refuge area. Those species are all threatened by increased fragmentation and predation.
  • This area of the Pilliga Scrub is prone to severe, high intensity fires that burn very quickly through vast areas. The proposal to have a massive compressor facility located in the Pilliga, and 550 well production sets, represents a very serious fire risk and has the potential to render a regular Pilliga hot burn to a catastrophic level.

Water resources

The Eastern Star Gas proposal suggests that it intends to use lateral drilling rather than hydraulic fracturing (fracking), but it does not explicitly prohibit or rule it out. There is inadequate assessment of the impacts on groundwater and aquifers, including the Great Artesian Basin. The proposal is extremely vague as to what it plans to do with the water that is produced as a by-product of the extraction process. Currently it states that it will use “a combination of storage and evaporation with tertiary treatment and discharge (environmental flows) for co-produced water management”. Produced water contains a range of naturally occurring substances that are likely to be harmful to the environment and human health. It is highly saline, and can also contain toxic drilling and fracturing chemicals. Eastern Star Gas commits to the development of a Water Management Strategy, but in the absence of such a strategy it is not possible to assess the potential impacts on biodiversity or the environment of produced water.

Take action to save the Pilliga Scrub

The Pilliga campaign will no doubt be the next big fight to protect biodiversity in NSW. The coal seam gas industry is expanding rapidly, and governments are largely taking the advice of industry on the environmental impacts.

As a first step, please send a message to the Federal Environment Minister requesting he reject the project under the EPBC Act. You can write your own personal email by contacting him here. Or simply fill out the form here to send him a generic message.

As the Greens environment spokesperson, together with my colleague Jeremy Buckingham as the Greens mining spokesperson, we’ll be building a campaign to save the Pilliga from coal seam gas and to protect its unique biodiversity. Check back here soon for more information on how you can help save the Pilliga Scrub.

‘Pilliga forest new CSG battlefront’

By Kate Ausburn, 20110618

.

The Pilliga State Forest in northern NSW will be turned into a gas field if the government approves Eastern Star Gas‘s (ESG) mining proposal for the region.  The proposal set out by ESG seeks to develop the Pilliga into the state’s largest coal seam gas (CSG) project.

The development would include the drilling of more than 1000 gas wells and the clearing of vast stretches of native bushland to make way for gas pipelines and other associated infrastructure, such as a water treatment facility and access roads.  ESG is already carrying out smaller scale gas development in the Pilliga, as the operator of the Narrabri CSG Joint Venture.

In 2006, ESG developed coal seam gas production pilot wells in the Pilliga.  A gas pipeline was also approved and built to carry gas from these wells to the Wilga Park Power Station, which was built by ESG in 2004.
As well as the wells now used to produce gas, some capped, unused gas wells remain behind barbed wire fences in cleared areas of the Pilliga.  At least one expansive pond holding wastewater produced by coal seam gas extraction sits amassing algae on its surface.
ESG’s plans for large-scale expansion of coal seam gas operations in the Pilliga have been criticised by environmental groups and landowners from the region.

The Greens NSW environment spokesperson Cate Faehrmann explained the scale of ESG’s proposal: “The proposed gas field development area covers approximately 85,000 hectares and includes Pilliga East State Forest, Bibblewindi State Forest, Jacks Creek State Forest, and Pilliga East State Conservation Area, plus some small areas of Crown Land and private land.”

Despite the NSW government’s recent introduction of “transitional agreements” to regulate the expanding coal seam gas industry, ESG’s Managing Director David Casey is hopeful about the future of his company’s proposal for the Pilliga.

In a May 25 Open Briefing document, Casey said ESG continues to “monitor opportunities and development pathways with a view to ensuring early commercialisation of the project for the benefit of shareholders …

“Currently, our best estimate is that Federal and NSW regulatory approvals will be in place … in early 2012.”

However, The Wilderness Society’s Warrick Jordan said on June 16 that “given the scale of the project and current uncertainty over NSW mining and planning policy” ESG’s timeline would be difficult to fulfil.

“Estimates of state and federal approval being in place in six months appear wildly optimistic
,” he said.

“The assessment requires full community consultation and proper consideration of environmental impacts on 85,000 hectares of forest, 1600 km of pipeline, a RAMSAR wetland, the marine environment, and the Great Artesian Basin.”

Local community and environmental groups came together on June 9 to tour the Pilliga and discuss campaigning strategy to minimise risks associated with coal seam gas and safeguard the environmental integrity of the region.

The coalition of groups will combine their efforts to campaign against expansion of coal seam gas mining in the Pilliga.

The Wilderness Society said on June 16:

“The project area in the Pilliga is a recharge area for the Great Artesian Basin and includes habitat for threatened species, endangered ecological communities, and an area protected under legislation for its natural values.”

Community Solidarity:

The Coal Seam Gas industry is selfishly exploiting Australian resources for corporate profit, much of which is channelled to foreign owners and investors offshore. In the process, coal seam gas exploration, drilling, fracking and the carcinogenic B-TEX chemicals used are destroying Australia’s natural environment and arable land – bulldozing habitat and spewing salt above ground, while below ground chemically poisoning Australia’s Great Artesian Basin and ground water.  The industry is one of extreme discretionary greed and arrogance, perpetuating local environmental rape, pillage and plunder.

If you think your area is the only one concerned about coal seem gas , think again.

The following communities around Australia are being exploited by coal seam gas corporations:

  • Camden, NSW

  • Helensburgh and the Illawarra, NSW

  • Pilliga, NSW

  • Liverpool Plains, NSW

  • Wellington, NSW

  • Gunnedah Basin, NSW

  • Gloucester, NSW

  • Broke, NSW

  • Wollombi, NSW

  • Northern Rivers, NSW

  • Cooper Plains, SA,

Introduced fire & cats killing The Kimberley

Thursday, March 24th, 2011
Golden Bandicoot is under threat of extinction in The Kimberley.

.

“Australia has the worst extinction record for mammals of all countries in the world (Johnson 2007), and has international obligations (Convention on Biological Diversity 2006) and national commitments (Commonwealth of Australia 1999) to avoid species extinctions.  Meeting these obligations will require effective and ongoing conservation management.”

[Source: Priority threat management to protect Kimberley wildlife, p47,CSIRO Ecosystem Sciences, Feb 2011, Australia]

.

.

.

At 6am on 1st June 1990, I started my prepared and serviced HT Holden outside my father’s place in Melbourne and executed my planned drive mission across to Adelaide then up the Centre to Kununurra in the East Kimberley.  I was 26; I had saved up.  I was on a mission to get my commercial helicopter license and to work in cattle mustering in the Kimberley in the process to ‘get my hours up’.

The Kimberley was a very hot and steamy; a world away from temperate urban Melbourne.

Well, after some months and growing up in a remote landscape, I did achieve  my license with Golden West Helicopters, then did some mustering. I took risks, recalling pivot turns over isolated beaches and I learnt a lot…what city kids should.

Some memories that will remain with me (until my memory doesn’t) are the waking to East Kimberley bird calls from the pilot shack at the red dusty caravan park down the road from Kununurra Airport.  When building my cross-county and low-level endorsement hours up, I will never forget flying the R22 low over wild rivers full of long lizards (crocs), or slowly navigating the thick mist at 50 foot AGL at dawn, or flying free over the wide rugged red rock landscape, or finding the eagles nest on a remote hill miles off in some north westerly direction from Kununurra.  My memory of the Kimberley is of a wild special place, like Emma Gorge and the amazing remote drive to Wyndham – so isolated – so free.  But it is the unique bird calls that recur in my memory of the magic natural tropical home of The Kimberley.

So when I now later learn that the Kimberley and its scarce wildlife are under threat, I have no hesitation posting the following article to advocate the urgency of the Kimberley’s wildlife conservation.

The Kimberley is indeed like nowhere else!

~ Editor

.


.

According to the findings of a current ecological study and report published in February 2011 by the CSIRO and The Wilderness Society:

up to 45 native species in the Kimberley region will die out within 20 years if no action is taken”.

.

The report found that the two most destructive threats to survival of native species are:

  1. Feral cats

  2. Frequent large scale fire regimes   (deliberate or neglected)

.

It has called for an immediate cash injection of $95 million to save wildlife like the Golden Bandicoot, the Scaly-tailed Possum and the Monjon Rock Wallaby from extinction.  Even with the current $20 million per year spent on Kimberley conservation the region is still set to lose some 31 native animals, according to the report.

The report is a culmination of collaborative ecological research and workshops was undertaking across the Kimberley region by scientists with the CSIRO’s Ecosystem Sciences, along with The Wilderness Society,  Australian Wildlife Conservancy, Fenner School of Environment and Society (ANU), and The Ecology Centre at the University of Queensland.  Its authors from these organisations include Josie Carwardine, Trudy O’connor, Sarah Legge, Brendan Mackey, Hugh Possingham and Tara Martin.   Regrettably,  the only contributing organisations permanently based in the Kimberley appear to be the Kimberley Land Council and Environs Kimberley.  Perhaps this is half the problem; the other half being ye ol’ lack of political will, because surely Australia has plenty of taxpayer funds in circulation.

If ever the ecological precautionary approach principle was a vital precondition of human actions, the Kimberley is the place where it most applies.  The recurring theme throughout the report is the lack of comprehensive survey data from the region.  Ecologically, the Kimberley is grossly data deficient.  Consequently, humans know not what they do, nor what the impact of what they do is, nor how close the thirty odd threatened and endangered native animals are to regional extinction.

The Scaly-tailed Possum (Wyulda) , Monjon Rock Wallaby and the Cave-dwelling Frog are thought to be uniquely endemic to the region, so if they are wiped out from the Kimberley, as a species they will become globally extinct, like the Tasmanian Tiger (Thylacene) and the Dodo.

.

Due to human encroachment and habitat destruction across northern Australia and the ferals and destructive practices they have brought with them, the still mainly wild Kimberley remains the last survival refuge for many of Australia native at-risk species.

Native vertebrate fauna of the Kimberley like the Northern Quoll, Golden-backed Tree-Rat, Golden Bandicoot, Gouldian Finch, Spotted Tree Monitor, Western Chestnut Mouse, and Stripe-faced Dunnart are at serious risk of extinction.

.

Priority Threat Management Actions for The Kimberley

.

Experts identified key broadscale threat management actions for improving wildlife persistence (p5):

1.    Combined management of fire and introduced herbivores! – feral donkeys, cattle, horses, pigs
2.    Eradication, control, quarantine of weeds! – rubber vine, gamba grass, mesquite, passionfruit
3.    Control of introduced predators! (particularly feral cats)

.

“The single most cost-effective management action would be to reduce the impacts from feral cats (at $500,000 per bioregion per year) with a combination of education, research and the cessation of dingo Baiting.”        [p.6-7]

.

While anticipated to have low feasibility of success, the feasibility has not been started nor tested.

“The next most cost-effective action is to manage fire and introduced herbivores (at $2–7 million per bioregion per year); this action is highly feasible and, if implemented effectively, would generate large improvements in probabilities of persistence for almost all wildlife species.” [p.6-7]

Threats to The Kimberley from ‘Bushfire Management’

.

“Frequent, extensive and very hot fires in the Kimberley affect its ecosystems in several ways. They change the structure and composition of vegetation, endangering some species of plants and removing important wildlife habitat refugia. They also leave the ground unprotected from the heavy monsoonal rains, causing soil erosion and later stream sedimentation.”

Inappropriate fire regimes pose a threat to biodiversity in the Kimberley and across northern Australia (e.g. Bowman et al. 2001; Russell-Smith et al. 2003). Historically, Indigenous people managed fire throughout the region, which included fine scale prescribed burning across a variety of vegetation types and around important cultural and food resource sites, such as rainforest patches. This most likely resulted in a mosaic of burnt and unburnt vegetation and provided buffers against unplanned wildfires around critical biodiversity refuges (Environmental Protection Authority 2006).

.

These fire patterns have been replaced in the past few decades with one that is increasingly dominated by extensive and intense mid to late dry season fires. As a consequence, the mean age (and variance) of the vegetation has declined (Legge et al. 2010).

Altered fire regimes interacting with other degrading processes, especially over-grazing, have led to structural and floristic change in vegetation, declines in vegetation cover and critical resources such as tree hollows. They are also associated with increased soil erosion after heavy rains (doubled erosion rates have been recorded in similar situations in the Top End of the Northern Territory (Townsend and Douglas 2000), leading to increased sedimentation in stream beds. These changes have severe negative impacts on native flora and fauna (Vigilante and Bowman 2004; Legge et al. 2008). Extensive flat savanna areas are more vulnerable to large intense fires, as there are fewer inflammable refugia such as rocky areas.

Without appropriate management, the impacts of fire are likely to increase as the region is predicted to become even more fire prone with ongoing climate change (Dunlop and Brown 2008)”. [pp.11-12]

Threats to The Kimberley from ‘Feral Cats’

.

“Invasion by feral predators has contributed to range reductions and population declines of many native animals in Australia; small to medium sized mammals have been particularly affected. The primary feral predator in the Kimberley is the domestic cat. Cats have possibly been present in the region since the 1880s and were established by the 1920s (Abbott 2002).

The number of cats occurring in the Kimberley is unknown due to difficulties in survey, although a radio-tracking study at Mornington Wildlife Sanctuary suggests there is one individual per 3 km², each eating 5–12 native vertebrates daily. If this population density of cats occurred throughout the region there would be over 100,000 individuals present, consuming at least 500,000 native animals every day (Legge unpublished data).

There is some evidence that dingoes, as a top predator, can help control the negative effects of smaller predators like foxes and cats (Glen et al. 2007; Johnson and VanDerWal 2009; Letnic et al. 2010; Kennedy et al. 2011). The regular baiting of dingoes is therefore likely to exacerbate the problem of introduced feral predators (Wallach et al. 2010).” [pp.13-14]

.

“The Kimberley is a national priority in this effort to avoid further extinctions due to its intact suite of wildlife species, including many endemics, and its role as a refuge for an increasing list of species that are declining or have been lost in other areas of northern Australia.” [p.47]
