Climate Change Less Threatening to Declared Reserves?

April 2, 2008 By neil

Last August, a panel of scientists from the Australian Greenhouse Office and the CSIRO (Commonwealth Scientific and Industrial Research Organisation), called on the federal and state governments to expand the number of nature reserves in Australia in a bid to protect animal populations from climate change.

Following on from Queensland’s climate-linked plan of doubling its declared reserves, the Federal Government has now pledged $180 million to expand the National Reserve System.

“Today’s announcement will help protect key habitats at a time when native species such as the mountain pygmy possum, tree kangaroos and hare wallabies need them most – as they struggle to adapt to the impacts of climate change,” Mr Garrett said.

WWF‘s Protected Areas Policy Manager, Dr Martin Taylor, said the $180 million funding boost was a promising step toward saving Australia’s wildlife from a “decade of neglect”.

“National parks and nature reserves are the proven best and most secure method of arresting declines of threatened wildlife toward extinction and buffering nature against climate change,” Dr Taylor said.

A little over 11 per cent of Australia is presently reserved, which is apparently less than many developing countries. However, associating declared reserves with protection unfairly suggests Australia is eighty-nine percent unprotected.

The irony of the entire exercise is that it is underpinned by an environmental ethos, held by the majority and enunciated through the bidding of elected representatives, but only if others pay it for. As far as I know, there has never been a transfer of reserved land into private-ownership for improved protection. It has only ever been the other way. Australia incrementally increases its reserve system, leaving an ever-decreasing off-reserve portion.

Perhaps a more inclusive and cost-effective national approach would be possible if our elected representatives represented the protective interests of land-holders off-reserve.

Beyond Media Headlines: The Key Issues for the Macquarie Marshes

February 26, 2008 By jennifer

Media reports yesterday** correctly drew attention to the fact that there are levy banks within the Macquarie Marshes and that they are depriving key wetland areas of water.

But the stories went on to lump upstream legal and planned irrigation development that makes allocations for environmental flows with legal and illegal levies on grazing land within the marshes. Some levies within the marshes are currently blocking designated environmental flow water from reaching the northern nature reserve.

Some of the media reports suggest a need for more studies, but the solution may simply be to bulldoze levies so that environmental flow can get through to the nature reserve.

Other issues within the marshes that require action, rather than more studies include:
1. Preventing the trampling of bird nesting sites by cattle, and
2. Addressing the general issues of overgrazing.

The Macquarie Marshes is a large non-termial wetland in central western New South Wales covering about 200,000 hectares. Most of this area (88 percent) is privately owned and grazed. There are two publicly-owned nature reserves where cattle are excluded and which are Ramsar-listed, meaning they are considered of international importance for migratory bird species.

The most definitive recent publication on the ecology of the Macquarie Marshes is:

Report reveals illegal Murray-Darling irrigation. By environment reporter Sarah Clarke
Scientists say the flood plains are being sucked dry and there is no legislation in place to stop further development.
A new report has exposed major flaws in the management of key rivers and flood plains along the Murray Darling Basin. Satellite images of a key wetland in north-western New South Wales reveal more than 2,000 kilometres of earthworks have carved up the waterway. While some of the channels and levees may have been authorised, others are considered illegal and are diverting water into irrigation and farming.

NSW vows crackdown on Murray-Darling earthworks
The New South Wales Government says it will crack down on unauthorised earthworks in the Macquarie Marshes in the state’s north-west. A report by the University of NSW found that more than 2,000 kilometres of channels, levees and dams are carving up the Macquarie Marshes and diverting water into irrigation and grazing areas.

Wetlands in a flap after the rains
February 25, 2008
Birds are winning the battle of the marshes, writes Daniel Lewis.
Wading through Monkeygar Swamp, with magpie geese honking in the sky above, even a vicious bite from the odd leech can’t wipe the smile off Ray Jones’s face.
There’s enough water for significant bird breeding in his beloved Macquarie Marshes for the first time since 2000, and the National Parks field officer is on a high after depressingly dry years.
“When you see these geese taking off you can’t help but smile,” Jones says. A fellow parks employee recently told him: “This is the first time I have seen you smiling for years.”

Blue Gums in Grose Valley Healthy After Back-Burning

February 3, 2008 By jennifer

Just over a year ago media reports indicated the Blue Gum Forest of the Grose Valley was “hanging in the balance” because of a wildfire made “more intense, unpredictable and extensive by massive backburning operations”.

I trekked into the forest today and was surprised and pleased to see a beautiful forest with little evidence of fire damage.

As I struggled up the steep escarpment on my way out of the valley, I passed a couple descending into the valley and I asked if they were planning to visit the Blue Gum Forest.

“Yes,” replied the women, “At least what is left of it”.

Like me, and so many Australians, she believed the media reports that the forest had been badly damaged. As we passed I suggested she would be pleasantly surprised by what she saw.

Why has reporting in the popular press been so negative? Was the state of this iconic forest misrepresented as part of a wider campaign against back-burning?

Melbourne Benefits from Killing Barmah Brumbies

September 24, 2007 By neil

Public submissions in response to the Draft Feral Horse Management Plan for Barmah Forest close today.

The plan proposes the removal of horses from the Barmah Forest firstly by using lure and trap techniques over two years, which will commence following the approval of a final plan. The removal program would be reviewed annually and all feral horses are proposed to be removed from the Barmah Forest within five years of the program commencing. The involvement of key stakeholders will be through comment on this draft plan. The feral horse removal program will be managed jointly by the Department of Sustainability and Environment and Parks Victoria.

In a note from Angela Downey of the Great Divide Team:

Earlier this morning we received notification that the Victorian Government and their able assistants, not content with killing the Legend of the Man from Snowy River, by their banning of the Mountain Cattlemen and their Barmah counterparts, it seems now they are set to remove another icon of Victoria’s heritage under the guise of saving the environment and questionable animal humanity reasons.

On Monday members of Parks Victoria will set about removing 150 brumbies from the Barmah Forest which covers an area of 75,000 acres. It is claimed this small number of horses are causing severe damage over this huge area.

A decision was made to remove the animals from the park following this years harsh drought and with another to possibly to follow, with the implication that this small number of brumbies would place the environment and the resident native fauna under undue stress due to competition for feed and water. Many of the horses live in small family groups and are spread throughout the park. No doubt it has been a harsh year for them and many of the other animals.

However no mention has also been made of the contribution to the lack of feed made by other feral animals such rabbits, wild pigs, goats, foxes, dogs and cats all of which inhabit the forest. Such other feral animals often have massive explosive populations and cause direct and monumental damage to the environment.

An option of using helicopters with snipers on board to do the deed was considered but due to the potential of a similar outcry such as the furor over the Guy Fawkes National Park slaughter of 2000. During that episode many horses were shot but died a slow and agonising death from bullet wounds.

The Victorian National Parks propose to round up the Barmah brumbries, destroy any stressed and old animals on site and remove the rest to the abattoirs.

These animals would be obviously suffering due to the current dry conditions as would the native fauna. . They are more than happy to leave the suffering native fauna to their own devices in the Park while also making little impact on the removal of other feral fauna with populations of thousands which happily munch their way through tonnes of native flora and fauna, digging holes, slopping around in bogs, and bulldozing their way around the Park.

The removal of the Brumbies will have little impact on the environment of the Park. One has to question the governments motives in removing this small population of an Australian icon and part of our heritage.

If Parks Victoria are actually so concerned with the plight of the brumbies there are other options out there.

Further recommendations have been made by the Victorian Environment Assessment Council in its River Red Gum Forests Investigation Draft Proposals Paper (which states):

Domestic stock grazing has occurred in Barmah forest for several generations. The average of 2000 (summer) and 800 (winter) head of cattle agisted in the forest has been reduced in response to recent drought conditions, culminating in the destocking of the forest for the 2007 winter term. There are also 7 current grazing licences covering a total of 78 hectares and with a total carrying capacity of 112 Dry Sheep Equivalent that would be included in the proposed national park. Grazing with domestic stock is incompatible with national park status and will not be permitted in the proposed park. As well as domestic stock, Barmah forest is also grazed by feral horses and deer which, together with feral pigs, should also be promptly removed from the proposed national park to protect its highly significant natural values.

In Chapter 4 of the report, Social, economic and environmental implications, a candid expression of economic impact is made:

A team of consultants led by Gillespie Economics was commissioned by VEAC to independently assess the social and economic implications of VEAC’s proposed recommendations. The consultants concluded that the proposed recommendations would result in a net increase in economic value to Victoria of $92 million per year excluding the costs of environmental water. The breakeven price for environmental water would be between $1320 and $2880 per megalitre. Most of the benefits from the proposed recommendations result from non-use values for environmental protection, which are heavily dependent on adequate environmental water. These benefits would accrue mostly to people outside the Investigation area, especially in Melbourne, while the costs of the proposed recommendations would be largely borne within the Investigation area particularly in the areas near where public land timber harvesting and grazing are focussed. The towns of Cohuna, Koondrook, Nathalia and Picola are likely to be most sensitive to these effects, as they would be occurring in the context of the contraction of local economies and populations in these areas that has been experienced in recent years.

This is yet another abrogation of environmental responsibility in a seemingly endless succession, as defined within the Intergovernmental Agreement on the Environment 1992.

As people and communities are included in the definition of the environment, the threat of serious or irreversible socio-economic damage (as identified by the consultants) should bring the precautionary principle into play. Under the policy principle of intergenerational equity, the present generation should ensure that the health, diversity and productivity of the environment is maintained or enhanced for the benefit of future generations. And, environmental goals, having been established, should be pursued in the most cost effective way, by establishing incentive structures, including market mechanisms, which enable those best placed to maximise benefits and/or minimise costs to develop their own solutions and responses to environmental problems.

The Cumulative Impact of Rainforest Research

September 9, 2007 By neil

Pig-exclosure.jpg

In the late 1990’s, a scientific ‘pig-exclosure’ project was established in the Cape Tribulation section of the Daintree National Park. The project involved the construction of an 80 metre square fence, anchored aggressively to the ground with steel trimmer bar and pegs. The site selection encompassed much of the very restricted, endangered and previously studied laurel, Endiandra cooperana.

The purpose of the project was to collect comparative data, inside and outside the exclosure, to quantify the adverse impacts of feral pigs upon seedling recruitment rates of an endangered plant species.

Criticisms of the project at the time included the accessibility by piglets into the exclosure through the mesh squares, the obstruction to cassowaries in a known corridor, proximity to two roads and the contention that even blind Freddy could see that pigs were damaging to seedling recruitment rates.

Despite these concerns the project proceeded and there it remained for many years. Eventually, the land manager agreed to remove the construction, but was so under-resourced it dismantled only one corner section and middle panel on each side, leaving around eight 30-metres sections of fence in the rainforest, where they remain to this day.

Mammal-chute(2000).jpg

In around the year 2000, another scientific study was carried out in the vicinity of the pig-exclosure project. This one sought to capture the primitive rainforest macropod, Musky-rat Kangaroo Hypsiprymnodon moschatus. The methodology required the placement of several hundred metres of plastic barrier through known habitat, stretched to form walls with strategic openings every thirty or so metres. The animals would familiarise themselves with the openings and after a period of adjustment, cages would be placed at the openings into which the animals would be herded by the research scientist. Once caged, they would be analysed and genetic material collected from hole-punched tissue from the ears of specimens.

Mammal-chute(2006).jpg

More recently, another similar project was transferred to the same locality from rainforest in the Cyclone Larry affected areas. Different plastic barriers were constructed, for the same purpose, but this time the project sought to map the liberation of captured animals by gluing a cotton reel to the released subjects so that the thread would leave a variety of passages that could be compared relative to the adjacent roadway, to determine whether roads had a quantifiable impact on evasive mammal behaviour.

All very interesting projects, but why are the researchers abandoning their materials in the forest?

Mountain Cattlemen Defy Government Ban

January 8, 2006 By jennifer

Last June the Victorian State Government banned cattle grazing in the Alpine National Park. A protest website emerged at about the same time.

According to the most recent newsletter from this website:

Several small mobs of cattle are continuing to move slowly across the Alpine National Park. This is a week-long protest by many Mountain Cattlemen’s families against the loss of their grazing licences and subsequent treatment by the Victorian Government.

While the focus was on one of the small and symbolic herds yesterday, today it is becoming apparent that there are several groups of cattlemen, each with a small mob of cattle. This protest is clearly being supported by mountain cattlemen from all sides of the Alpine National Park, all wanting a return to alpine grazing.

The cattle and their drovers will be on the track for the next seven days as they travel to the annual Cattlemen’s Get-Together to be held at Rose River near Whitfield next weekend. The cattle are not in the Park to graze, they are travelling through.

The protest is being fully supported by lobby group Country Voice and the Mountain Cattlemen’s Association and many other groups concerned at the direction the Victorian Government is taking with public land and national park management

These small mobs are travelling on the original stock routes and bridle tracks across the Victorian High Country. The mountain cattlemen have been banished by the Bracks’ Government from the Alpine National Park for its political gain but at Australians cultural expense. end quote

According to Peter Attiwell quoted at my blog post of 16th June last year:

The critics of alpine grazing use science to support the basic tenet that grazing is incompatible with use of the land as a national park, as encapsulated in the slogan ‘National Park or Cow Paddock?’. The slogan is totally misleading. A cow paddock, once abandoned, will never return to the ecosystem that was destroyed to create it.

In contrast, there is no evidence that cattle grazing in the High Country has eliminated rare and threatened species, nor has species composition or diversity been irrevocably altered. Indeed, 170 years of controlled cattle-grazing has left by far the greater part of the High Country in excellent condition. Clearly, at the long-term and landscape levels, cattle grazing over some part of the High Country can be accommodated within management plans to achieve specific goals without an irreversible deterioration in biodiversity. end of quote

It is interesting to ponder that grazing was only allowed in about 15 percent of the Alpine National Park. Many may argue that there should be no grazing in National Parks. But what about Ramsar Wetlands? Most of the Ramsar Wetland listed Macquarie Marshes is grazed and there is evidence that this is having a significant negative impact, click here for earlier blog post.

We have a very adhoc and political approach to environment protection in Australia.
