Great lockdown reading 3: Castlemaine’s first environmental conflict

One of the heroes in Marjorie Theobald’s narrative is Gold Commissioner Captain John Bull. The author builds on her previous research on one of the problems he faced:

Decaying puddler, Cobblers Gully: it’s picturesque now, but in its day it was a menace to the health of people and the environment.

‘As concern for the environment as we understand it today did not exist on the goldfields, it comes as a surprise that  in early 1855 Captain Bull took a stand on precisely these grounds. He sent to each puddling machine proprietor an edict that from the 31 March 1855 these machines would be banned from the main creeks in his district. This was necessary, he said, to safeguard the water supply of Castlemaine, the operations of miners using conventional methods, and the health of the creeks and flats generally. The problem was that the end product of the puddling machine process was a murky treacle-like sludge which had begun to pollute the creeks and choke the flats…

‘The reaction of the puddling machine men was swift. They (argued) that they had invested large sums of money in the erection of machinery, that puddling was important to the economy of the goldfields…and that such an edict would effectively shut down all future technological development in the industry…’

In this face off of environmental and community health on the one hand, and the economy on the other, guess who won? Of course, the alleged conflict between the economy and the environment and health is a false one, but it’s tenacious all the same, as we are seeing at this very time…

Oceans of blossom, thousands of questions

The photo below shows fields of Woolly Wattle south of the Wewak Track, east of Porcupine Ridge. The wattle is interesting (and beautiful, of course) for the fact that its blossom can vary from pale yellow to dense lemon colour, often on the same plant.

Also interesting, in this case, are the blackened tree trunks, the result of a management burn in 2010. Before this fire, the burn zone was open woodland, with an understorey of tussock grass and shrubs. Now it’s virtually impenetrable, a dense thicket of Hedge Wattle, Woolly Wattle, eucalypt saplings and other growth.

Oceans of Woolly Wattle (Acacia lanigera) framed by the blackened trunks of eucalypts burned by DELWP in 2010. The message is: fire has a complex biological role in our bushland, and reduction burns sometimes produce rampant regrowth in the medium term.

Compare the above with the photo below taken in the same zone after the 2010 burn. At the time FOBIF was shocked at the severity of the fire, which killed many large trees.

The same zone, November 2010: the intense fire has produced dense regrowth, probably the most impenetrable in the region

The lesson to be drawn from these two photos: fire can regenerate as well as destroy. We don’t know what effect this management exercise has had on the zone, biologically, because we haven’t seen the before/after monitoring…if there is any. From the point of view of fuel reduction, however, it seems to have been counter productive.

This is not an argument against fuel reduction burns. But it is an argument for exercises which are better resourced, better researched and, perhaps, better managed.

New find in Muckleford Forest!

A small population of a daisy-bush never found in Mount Alexander Shire before (as far as we know) has been discovered in bushland to the north of Newstead. Found growing under Grey Box and Yellow Gum trees, the erect daisy-bush stands 30cm tall with lilac flower-heads approx 10mm diameter. Experts at the Royal Botanic Gardens Herbarium in Melbourne identified it as Olearia floribunda Heath Daisy-bush.

Perhaps why it hasn’t been noticed before is that when the Heath Daisy-bush is not bearing flowers, at a distance you could easily mistake it for two other local species
which are abundant in the same area – Cassinia sifton Coffee Bush/Drooping Cassinia, or Ozothamnus obcordatus Grey Everlasting. These 3 species are all in the daisy family (Asteraceae), but they each have very different flowers so you would never get them mixed up if they were flowering.

OK, it’s not a cascade, but it’s the best we can do…

The gouged and eroded gullies of our region are a heritage of the gold rushes, a time when an unknown quantity of topsoil was lost through deforestation and creeks were scoured for gold. There are a few reminders, however, of how creeks might have looked in former times: rock walls and formations suggestive of flowing creeks and permanent pools. One such is pictured below, after last week’s rain: chain of ponds in the Railway Dam catchment. It’s not Niagara, but for the moment it’s the best we can do–and right now it’s rich in mosses, lichens and fungi.

Rock wall with water, Tunnel Hill, April 26: ‘waterfalls’ like this rarely flow, but they are reminders of a time when our waterways were more reliable and abundant.

FOBIF goes around, again

FOBIF has made a submission to the inquiry by the Inspector General for Emergency Management [IGEM] into the 2019-20 Victorian fire season. The inquiry is broad, ranging over topics like education, operational responses, evacuation planning, the use of the Australian Defence Forces, and many others. Our brief submission focused on two of terms of reference: resourcing of land management, and the biodiversity implications of fuel reduction. The substance of the submission is below:

We wish to offer a brief submission to the enquiry under two categories:

1 In the context of bushfire preparedness, assess the readiness and responsibilities of statutory agencies, Local Government and State Government bodies.

In our view land management in Victoria is seriously underfunded. A quick check of the budgets of Parks Victoria over the last ten years, for example, will show an effective decline in funding, even though the responsibilities of Parks staff are wider—there are a nearly a million more people in the state than there were ten years ago.

Large Yellow Box hollowed out by DELWP fire, Railway Dam Road, April 2020. It’s not Department policy to destroy large trees, but it inevitably happens in reduction burns…

One of the consequences of this funding inadequacy is that fuel reduction exercises tend to be crude and unnecessarily damaging. We note the following, from the Carter enquiry into the disastrous Cobaw fire of 2015, a reduction burn escape:

‘Interviews [with DELWP staff] also revealed that there is a resignation by staff that district resources and budgets are tight and this may result in resources at a burn being “thin”. The Investigation Team noted that many of the staff interviewed commented that the resourcing for the  Lancefield-­‐Cobaw  burn  was not optimal however “we do what we can with what we have” or “we are just used to managing with what we have”.’

We have heard this story from fire managers many times. For example, we have yet to see a fuel reduction burn which does not unintentionally destroy large trees [contrary to Department policy]: this is because managers don’t have the person power to survey the zone in question and institute measures to protect such valuable assets.

We urge IGEM to strongly recommend adequate resourcing to both DELWP and Parks Victoria.

2 Review … all opportunities and approaches to bushfire preparedness, including different methods of fuel and land management (for example ‘cool burning’, mechanical slashing, integrated forest management, traditional fire approaches) to protect life and property as well as ecological and cultural values.

All of the above approaches have their merits. Our concern is that in recent years, especially during the time of the five per cent burning target, most fuel reduction efforts have been directed at ‘cool burning’ .

This is the tree pictured above. It’s almost certain to fall. The biodiversity implications of reduction burns are largely unknown. Although managers are increasingly aware of this, a disturbing number are overconfident that the bush ‘always comes back.’

All too often ‘cool burns’ have been very hot, with resultant dense regrowth of flammable bush]. Fuel in such cases has not in fact been reduced. We could point out many cases where one side of a track, recently burned, is dense with wattle and eucalypt regrowth; while the other, unburned, is open grassy woodland.

We urge that where fuel reduction burns take place, they should be done in small area lots, allowing careful assessment of both fuel loads and environmental values. Too often in the past the Department has drawn lines on a map and lit a fire without too much concern about the biodiversity impacts of the exercise. The result is suggested in the 2019 State of the Environment report:

‘Biodiversity impacts from planned fires and bushfires at regional and statewide scales are currently unclear. An approach to monitor biodiversity responses (flora and fauna) to fire at multiple scales (regional and statewide) is missing.’

We realise that reduction burns in small patches could be an expensive exercise. Our question is, how valuable is public safety and the environment we live in?
