Fire: it’s not just a matter of fuel reduction

Fire officers met the public in a lengthy consultation session on the draft Fire Operations Plan [FOP] through the afternoon and evening of last Tuesday [August 11] in Bendigo.

An excellent link to the relevant documents with comments on the FOP in the Muckleford-Maldon area can be found in the Muckleford Forest Blog. In addition to burns discussed there, FOBIF is most interested in proposed burns in the Taradale, Tarilta and Fryerstown areas.

Aninteresting feature of the consultation was the display of Risk Landscape material. Readers will remember that this is the system most likely to replace the current crude five per cent burning target.

It was clear from discussions with officers that as far as on ground work is concerned, it’s early days with this system. For example: as is clear from the map above, most of the ‘priority fuel load’ areas in our region are on private land: yet we were told on Tuesday that negotiations via the CFA and municipal councils to undertake systematic fuel reductions in these areas are not far advanced: and that nothing had yet taken place on the ground in the Mount Alexander shire.

Into the valley

A solid group of FOBIF walkers led by Richard Piesse dropped in to the Tarilta Valley from Porcupine Ridge on Sunday in brisk but fine winter weather. There was good bird watching and plenty of fungi on show, and the valley is showing fair but patchy recovery from DSE’s disastrous 2012 fire exercise.

Taking a break by the Tarilta Creek.

The group left the valley via the impressive rock cleft and waterfall ridge [which, unfortunately, rarely sees much water – see first photo below], and wound its way through an isolated subsidiary valley to the Great Dividing Trail.

Noel Young sent us the following observations:

The bird life was fairly active in the area, and I was able to identify the following either by site or call:
Thornbill flocks, White throated Treecreeper, Golden Whistler, White eared Honeyeater, Grey Shrike-thrush, Spotted Pardalote, Long billed Corella, Sulphur crested Cockatoo, Crimson Rosella and Horsfield’s Bronze Cuckoo. 

 Two Black Wallabies crossed the Porcupine ridge road on the way in.

 I didn’t attempt a plant list, but there were several species of wattle flowering, including an unusually common occurrence of A gunni. (Ploughshare), a number of flowering Sundews, and an occasional Hovea and white or pink heath flowers. No flowering orchids were found as far as I know.

Roadsides: is scalping just management on the cheap?

Following its objections to roadworks scalping valuable vegetation from the Fryers Ridge, FOBIF has written to the Environment Minister asking for clarification of policy on vegetation management of roadsides.

The letter reads, in part:

“Forest managers have told us that, though this method of vegetation management is not ‘ideal’, budgetary restraints prevent them from using more labour intensive methods—like selective removal of obstructive vegetation, or moderate grooming. Further, there seems to be a common assumption in the Department that ‘priority to safety’ means absolute disregard for environmental values, when it should mean: careful management of vegetation to maintain sight lines and encourage sensible driver behaviour.

Fryers Ridge, July 2015: the road is the strip in the background. Managers plead that budget restrictions mean that 'scalping'--scouring the earth--is the only option they have in managing roadside vegetation.

Fryers Ridge, July 2015: the road is the strip in the background. Managers plead that budget restrictions mean that ‘scalping’–scouring the earth–is the only option they have in managing roadside vegetation.

“Our group is fully aware of the necessity to maintain proper fire access roads, and to manage adjacent vegetation to minimise the likelihood of accidents. We believe, however, that this should be done with minimum of disturbance to  environmental values. We assume that Victoria adheres to the common principle ‘avoid, minimise, mitigate and lastly offset’ in its road management policy?

“Given that managers often justify crude practices by appealing to budget limitations, we have four questions:

  1. What is the Department’s [and the Government’s] policy on roadside scalping?
  2. What is the Department’s 2015-6 budget for a. Forest management and b. conservation reserve management, compared to the same figures of 2005-6?
  3. Do the native vegetation clearance regulations which have been the subject of recent community consultation apply to the Department’s own managers?
  4. Is there any monitoring of the effects of roadside clearing on the environment?”

As this post is being written, controversy sputters over the destruction of 900 ancient river red gums as part of improvements to the Western Highway: seemingly another exercise by government in which ‘safety’–or in this case, speed–sweeps aside any other considerations.

Clearing: a regulation problem

The state government is reviewing native vegetation clearing regulations, which readers will remember were weakened by the previous government on the grounds of loosening red tape. The terms of the Review can be seen here.

As part of the review, FOBIF representatives and members of other conservation groups, DELWP, the CMA, developers and organisations like bee keepers, farmers, miners and prospectors, attended a consultation session at DELWP Epsom on July 22 to discuss the issue.

As can be imagined from such a disparate gathering, it seemed that almost everyone has an issue with current clearing regulations, but often for conflicting reasons.

Some of the issues raised in the meeting were

  1. Lack of resourcing – (staff and funding). This impacts on
  • Accuracy of mapping: Department maps are often desktop interpretations based on priorities under the environment protection laws [Environment Protection and Biodiversity Conservation Act/Flora and Fauna Guarantee], with no input of local knowledge. The maps are often wrong, sometimes to the advantage of the environment, sometimes to the advantage of developers; this leads to widespread lack of faith in the process.

Does frequent fire damage the soil?

A study presented at Melbourne University Burnley on August 5 offered strength to an argument that’s been going around for a long time: that high frequency severe fire damages soil. The argument has often relied on common sense and anecdotal evidence, but until now there’s been little rigorous analysis of the facts. This study remedies the deficiency:

‘[The] study investigated the effects of 27 years of repeated low-intensity prescribed burning in dry sclerophyll eucalypt forests in south-eastern Australia, focusing particularly on litter and soil Carbon and nitrogen (N). Four prescribed fire treatments designed as factorial combination of two fire seasons (autumn and spring) and two fire frequencies (high frequency – burning in 3-yr cycle and low frequency – burning in 10-yr cycle) and un-burnt Control were studied…

Severe management burn: a Melbourne University study has shown that such an exercise, repeated at 3 year intervals, causes severe soil damage.

Severe management burn: a Melbourne University study has shown that such an exercise, repeated at 3 year intervals, does ‘reduce key indicators of soil productivity’.

‘This study provides empirical evidence that high frequency prescribed fire does indeed reduce key indicators of soil productivity, and therefore that longer burning interval (c. 10 years) may be required to maintain a long-term ecological balance in dry sclerophyll eucalypt forests or similar forest ecosystems.’

Studies like this are a sobering reminder that long term damage to the forest is built into a major part of the current fire defence system: namely, the Asset Protection Zone, which under current policy is set to be burned every three years. For a long time managers have conceded that these areas of land are ecological sacrifice zones.

In theory the detail of the research can be found through a webinar at : https://unimelb.zoom.us/j/611678161            but we found the link difficult to access.

The future, and how to deal with it…

The North Central Catchment Management Authority is holding a series of forums on climate change, the natural environment and sustainable agriculture in the region through August. The Castlemaine forum will be held at the Campbell’s Creek Community Centre at 7 pm on August 31.  A light supper will be provided. Contact the CMA to RSVP for catering purposes [info@nccma.vic.gov.au or phone (03) 5448 7124]. The CMA’s Climate Change Mitigation and Adaptation Plan can be found here.

And a seminar in October organised by the Royal Society, Melbourne University and the VNPA will look at the likely effects of climate change on water, fire frequency, weather events, dry forests, and numerous other subjects connected to the theme of biodiversity. An impressive range of scientists will speak at the seminar. The program document introduces the subject in this way:

‘Assuming ongoing high levels of global greenhouse gas emissions, temperatures in Victoria [in 2050] would be 1.2° to 2.5°C warmer than recent decades. Around the state, temperatures above 40°C in summer would occur two to four times more frequently, and

Presentation on local butterflies

Julie Whitfield of Bendigo is an environmental consultant with a passion for butterflies, and she will be guest speaker at Newstead Landcare’s next meeting, Thursday 20th August.

As a recipient of a prestigious Winston Churchill Fellowship Julie recently had the pleasure of exploring conservation projects for butterflies in the USA and the UK with the dream of bringing these models back to Victoria to apply with our local groups.

Julie will provide a presentation on these experiences and on the butterfly species likely to occur in the Newstead area, and their role in local ecosystems.

Mount Alexander Shire has a few populations of the extremely rare Eltham Copper Butterfly which has an extraordinary relationship with a particular ant species and Sweet Bursaria shrubs. Julie will introduce you to this marvel as well as to some of our more common local butterflies.

All are welcome to attend the talk on Thursday 20th August at 8 pm at Newstead Community Centre (gold coin donations appreciated). No need to book in – just come along, discover and be inspired!

Mysteries, activities

A full house turned up at the Ray Bradfield rooms for the FOBIF AGM last Monday to hear Sarah Lloyd talk about slime moulds , mysterious life forms which are neither slime nor moulds. Sarah interspersed her entertaining talk with beautiful photos of these living things which are not plants, or fungi, and have some qualities which could put them in the animal world: that is, that they move about, eat things, and leave excrement behind them. She also projected a quite spectacular poster of line drawings of microscopic species by German naturalist Ernest Haekel and tossed off the information that movements of slime moulds might provide models for human transport systems. Discussion took unexpected turns when one audience member claimed to have kept one as a pet, and another drew comparisons with life forms evoked in science fiction stories. Samples were passed around the audience, and we can report that—unlike in the not quite famous Steve McQueen SF horror movie The Blob— no one was devoured by the specimens on show.

Sarah is author of the irrepressible guide, Where the slime mould creeps, obtainable from the Fungimap bookshop . In introducing Sarah, Cassia Read described her work as ‘an ode to nature’. Sarah lives in the forest on Black Sugarloaf  Mountain in Tasmania, where she has been conducting detailed studies of the mountain environment for many years–a year long study of the dawn chorus, a detailed record of local fungi, and occasional publications like Life in the shadows, the natural history of Black Sugarloaf, and The Blue Tier, a natural history. 

The meeting started with a photo montage on Doug Ralph, founding president of the Friends, followed by a report by FOBIF President Marie Jones. Marie thanked members for their work during the year, and gave a brief run down on the group’s activities: we are actively engaged in lobbying DELWP on forest management issues, take a keen interest in planning matters which may affect the health of our bushlands, and have lately taken on successful education programs for young people, from primary school to teenagers. Our recent field guide to mosses has almost sold out, and a second, revised edition is in preparation; we are also preparing a guide to local eucalypts. Our monthly walks continue to attract very healthy numbers.

After the treasurer’s report, Secretary/Public Officer Naomi Raftery declared all committee positions vacant, and conducted elections. Nominations had been received for all positions before the meeting, and according to the constitution, all nominees were therefore declared elected:

President: Marie Jones; Vice President: Neville Cooper; Secretary: Naomi Raftery; Treasurer: Lynette Amaterstein; Ordinary members: Elvyne Hogan, Frank Panter, Bronwyn Silver, Bernard Slattery.
