Not Just Bandicoots! – Hans Brunner

Not Just Bandicoots.

Bandicoots are a unique marsupial abut the size of a young rabbit and are closely related to the much adored bilby. Females have a pouch like kangaroos but their pouch is opening backwards so that the young have to get in and out through the “backdoor”. This is because bandicoots dig in the soil for grubs and, hence, would fill their pouch with soil.

They have a long nose with a highly developed olfactory system. Their long nose is lined with lots of sensitive receptors and neurons in order to detect food buried deep in the soil. They can detect the exact location of a grub 20 cm deep under the soil and pin-point exactly to it when digging for it.They dig very rapidly with their long fore-claws and within seconds they find their meal.

In addition, their conical diggings left behind are of great importance to the environment (Patricia Flemming etal). These diggings increase soil turnover, alter plant community composition and structure, trap rainwater for better water infiltration, capture bio-mater for nutrient cycling, and add to fungal and seed dispersal.

The presence of diggings can also prevent tree mortality and tree-die-off while the dispersal of fungal spores will speed up leaf-litter break down and so reduce the fire hazard.

Sadly, bandicoots are extremely vulnerable to the introduced predators such as dogs, foxes and cats as well as the reduction and fragmentation of their habitat. They are now on the national endangered list. One would think that the extreme usefulness and aesthetic value of these cute animals would be enough to want them to be protected at all cost but thus is not the case.The problem: they are not as popular as a kangaroos, or a koalas and are not quite like bilbys.

The Eastern Barred Bandicoot is one of Victoria’s most endangered marsupials, with over 99% of their native grassland habitat cleared for agriculture and urban development. The species in Victoria is now classified as ‘Extinct in the Wild’, and small Eastern Barred Bandicoot populations only exist due to captive breeding programs in wildlife parks and key locations around the state.

Southern Brown Bandicoot’s declining numbers in south east Victoria

THE federal Department of the Environment earlier this was trying to take the southern brown bandicoot off its threatened species list. However, Federal Environment minister Greg Hunt rejected claims his government doing this. He was responding to an article pub­lished in The Times last month (‘Bandicoot under threat from govt’, The Times 26/1/15).

In 2001 when the species was put on the endangered list, a SBB recovery groups was establish and they were selected as the flagship species in the Western Port Biosphere Reserve, to receive special attention. Hundreds of people, including scientists and government agencies, private consultants and landholders had workshops, and the Victorian government created strategy after strategy to protect them, but nothing worked.

A proposal for habitat corridors for the SBB in the draft Biodiversity Conservation Strategy, released in 2011, was withdrawn by the State Government and revised using consultation. The proposal is that there should be at least two 80m wide corridors leading to reserves to the south and reserves or Green Wedge land to the east – to ensure the sustainability of the species. The former Growling Grass Frog corridor along Clyde Creek should be reinstated.

There is too much of the Biodiversity Conservation Strategy that’s left to the Precinct Structure Planning process, rather than an independent role of a monitor to ensure impartiality.

In March 2014, the Coalition state government removed habitat corridors from its plans to protect the southern brown bandicoot in the southeast. and DEPI and Parks Victoria declared a secret war on Southern Brown Bandicoot ~ April 2014

Once common in the south-east, now, just two viable populations remain in the region – at Royal Botanic Gardens in Cranbourne and in undeveloped parts of Koo Wee Rup at the northern end of Western Port. A third population on Quail Island in Western Port has been decimated by wild pigs released on the island by hunters. The SBB is listed as an important component of the Ecological Character of the Western Port Bay Ramsar site and there is continuity of local populations of bandicoots with areas traversed by the Koo Wee Rup Bypass

They proposed to conduct regulars fox and cat control programs in the Pines for the protection of this species, knowing very well that SBB’s are not there anymore.(Already costing well over $ 100.000.00) They refuse to install a predator-proof fence around the Pines which is the only realistic way to protect the SBB in the Pines ones re-introduced. (They just want that money)

Ecologist Hans Brunner, from Frankston, has been involved with Southern Brown Bandicoots (SBB) for more than 40 years. He vividly remembers finding SBB all over the Mornington Peninsula, in the Frankston area, and especially in the Pines Flora and Fauna Reserve which had the larges and strongest colony in the region. Sadly, they have silently disappeared and in many places they’ve become extinct!

How could this happen?

Local wildlife expert Mr Legg said evidence of SBB populations recovering in a couple of places in Australia was no reason to remove legal protection. He had “reluctantly watched the crash and local extinction of SBB populations across the southeastern suburbs of greater Melbourne and within the Western Port catchment” over the past three decades.

The SBB is facing strong competition from housing growth, and urbanisation. The number of dwellings in Mornington Peninsula Shire is forecast to grow from 84,177 in 2011 to 95,955 in 2026. It’s the housing industry that’s become Victoria’s greatest growth industry, and the urban growth boundary is a slippery concept, that keeps expanding with population growth.

At least $120,000 was spent on fox and cat control, while some SBBs remained. It was unsuccessful. Protecting SBB in the region is a grand failure. What’s needed are large reserves surrounded by predator-proof fences. Some insurance colonies are need, with the rest surviving in the wild.

What’s to be gained by de-listing the SBB? Money will be saved by not having to spend in fox and cat control, and developers will be given more permits to build housing.

Jennifer Cunich, executive director of the Property Council, of course would not endorse any expansion of wildlife corridors. She dismissed any science, and any scheme would be of little benefit. It would be like a brewery recommending an AA group!

The SBB is restricted to remnant and exotic vegetation along drains and road reserves in the project area and surrounding landscape which provides cover from predators.

The VicRoads Bypass alignment intersects habitat for the SBB along the existing Healesville Koo Wee Rup Road to the south of Manks Road and core habitat of the Dalmore Koo Wee Rup Cluster of bandicoots at Railway Road/disused South Gippsland Railway Line and levees of the Bunyip River Drain Complex.

There’s no room for complacency, or sitting back watching decline. What’s needed now is to repopulate the Pines Flora and Fauna Reserve, and protect the colonies at Cranbourne Botanic gardens. Australia has the highest mammal extinction rate of the modern world, and any “fauna” reserve and green wedges must have local native species. It’s easy to say there are “plenty” elsewhere, but extinction is a process, not one event, and allowing local extinctions is part of a process that MUST stop!

The Southern Brown Bandicoot Dilemma- Hans Brunner

The SBB dilemma

For the last 13 years, the nationally endangered Southern Brown Bandicoot has been proclaimed with great hype and expectation as a flagship species in the local biosphere region. They were still prevalent on the Mornington Peninsula and in the Frankston area including the Pines. Sadly, because of incompetence and to a degree of unwillingness by DEPI and Parks Victoria, this species has now become totally extinct on the Pen. and in the Frankston area including the Pines.

The Southern Brown Bandicoot Recovery Group (SBBRG) was also not able to arrest this loss. Their current strategies to just provide corridors for them in order to restore them to where they have been lost has also failed. Wildlife corridors are extremely appealing to most people, but there is very little understanding of the many implications and difficulties involved. For example, what fauna species are still there to use them, is the vegetation type suitable along the whole length of it and can the wildlife to use it be properly protected form dogs, foxes, cats and cars etc. And where would such a linkages come from and lead into. Is it worth to construct expensive infrastructures for the animals that may be left in the area.

In one instance, $20m dollars were spent on underpasses in the Pines for the Southern Brown Bandicoot but there were no bandicoots left to use them.

During a recently held Biolink Forum at the RBGC the great enthusiasm and passion for these links has not changed. The SBBRG still insists to just only relay on providing corridors for bandicoots. Some of the proposed corridors are at least ten km in length and without fences to protect the animals from predators.They recommend to use “functional wildlife corridors between state nature reserves and to wildlife corridors in Frankston from the RBGC” but at the same time believe that fencing of the Pines is a lost cause and time could be better spent on other issues. Why then, create a 10 km long corridor from the RBGC to the Pines and to other similar distant places when there is no intention to re-introduce and properly protect bandicoots in the Pines and in those other reserves? When considering that we have dismally failed to protect bandicoots in at least 12 conservation reserves on the Pen. and in Frankston, it begs the question whether they can realistically be expected to just survive in narrow,long and unprotected corridors.

Fortunately, some people of the Natural Resources Conservation League of Victoria agree with me and recommend “Fencing of key nodes looks likely being one of the immediate priorities. This would include the Pines first and foremost”.

If this type of absolute protection for bandicoots is not accepted, then. the other currently recommended strategies of just corridors will create a much greater threat to bandicoots then that of dogs, foxes, cats, cars and developers put together!

As if it could not get worse. There are suggestions to introduce the Eastern Barred Bandicoot onto Churchill Island, French Island, Woodley School Reserve and even onto Quail Island, all being habitat that should be reserved and used for the SBB’s.

It looks like our flagship species, the SBB is now well and truly torpedoed and sunk and the governments at all levels do not seem to care.

Urban sprawl threatens Southern Brown Bandicoots — Western Port Bay, Vic

SouthernBrownBandicoot_creditReinerRICHTER

Ecologist Hans Brunner:

Bandicoots, the problems and the answer.

MY CONCERN IS the survival of Southern Brown Bandicoots (SBB) east of Melbourne and especially within the biosphere region around Western Port Bay. This is the site where during the last twenty odd years 95% of them were lost. The reason for the loss of the SBBs was the combination of incompetent and unwillingness by the then governments of Department of Environment and Sustainability, and Parks Victoria, failure to properly protect them there.

(So the very government agencies we expect to uphold the protection of wildlife and habitats are actually failing!  Promoting urban sprawl now is endemic to our culture, our economy?  Editor)

And now, the new Department of Environment, Land, Water & Planning (DELWP) plans to create a large new urban estate adjacent to the Royal Botanical Gardens Cranbourne (RBGC) called the Botanic Ridge & Devon Meadows. This area was previously covered with prime bandicoot habitat land — and now have to be somehow compensated for.

(Strange how the names of some streets and housing estates take on names that represent exactly some of the natural features lost under concrete — “botanic” and “meadows”, editor.)

Since then. I have attended four workshops with DELWP, SBB experts, public servants and environment consultants, about 25 people per session.

I was extremely disappointed that DELWP still insists in the continued use of only narrow corridors as a compensation for the loss of all the SBB habitat. I have earlier explained to them in great detail why these narrow corridors will definitely not be suitable for SBBs. Unfortunately, there seems to be absolutely nothing that I could do to change their mind. They were also not prepared to apply an actual Population Viability Assessment (PVA) to the area. All they did was talk about the use of it, but did not apply it, in order to prove that SBBs could safely survive in these conditions for at least the next hundred years! To me, this looked like 90% of political overbearing and only 10% of environmental input. No way could a PVA pass a test here and neither can artificial and narrow corridors be used for SBBs.

I have therefore consistently insisted that SBBs can now only be properly secured within large reserves surrounded by a predator proof fence. There are several such reserves suitable for this purpose such as the Pines, the Langwarrin Reserve and the Briars. SBBs can then be safely protected from dogs, foxes, feral cats and from competition from rabbits. Why has so much gone wrong with DELWP? Is there not one person among them who understands and loves SBBs enough to give them the deservedly highest protection available?

I now urge DELWP to urgently carry out their obligation and to put those SBBs safely into some large reserves the same way they are protected in the RBGC. I will be extremely frustrated if this is not done. Only the highest possible protection for them can now do.
