Remember the thinnings trial?

The ecological thinnings trial was conducted about 15 years ago in four locations in the box ironbark region. Locally the thinnings plot is in the Diggings Park along Morgans Track, between the Chewton-Fryerstown Road and the White Gum Track.

The principle behind the trial is as follows: devastation of the forests following the gold rush led to the destruction of most large trees, and regeneration of dense stands of saplings. The original woodland structure of reasonably widely spaced large trees was thus replaced by what we mostly have now: forests dominated by relatively spindly trees. These forests are naturally thinning themselves, with the gradual death of weaker trees, but the process is taking a long time. The thinnings trial is designed to hasten the process, by taking out relatively weak trees, thus allowing the better trees to grow more robustly, and thus creating a healthier woodland structure.

Section of the thinning trial near Morgan’s Track…

The project had a biodiversity aim: that is, it was intended to produce a better environmental outcome, not just straighter trees.

FOBIF did not oppose the trials, though we thought it was just as well to let nature do the thinning over time, and we were sceptical of the capacity of managers to maintain a credible monitoring program over a long enough period of time to show how effective the program was going to be.

Well, so far, so good, as far as the monitoring is concerned. A recent paper by researchers from Parks Victoria, DELWP and the Arthur Rylah Institute has given an account of the story so far in the thinnings plots. The conclusion of the paper is that tree growth in the plots is significantly higher than in adjacent control areas:

‘Three thinning treatments, differing in their density and pattern of retained trees, were compared with controls to determine the most effective approach for restoring these systems and increasing the rate of recovery for biodiversity benefits. The thinning treatments applied different retention levels of stems, one which reflected conventional silvicultural practice and two designed to reflect a patchy forest structure. The response of tree diameter growth to thinning treatments, for multiple tree species, was examined approximately a decade after thinning. All three thinning treatments increased tree growth-rates similarly (0.32–0.57 cm/yr), compared with the controls (0.2–0.27 cm/yr). These data suggest that the choice of thinning treatment may not be critical for accelerating tree growth, and land managers can focus more strongly on the treatment that provides the best overall outcomes for biodiversity.’

…nearby section of unthinned bushland. The principle behind the project is that thinning produces a more natural and biodiversity rich woodland structure.

There’s a long time to go, of course: in a drying climate, and with poor soils, growth rates are slow.

The paper is jointly written by Geoff Brown, Andrew Murphy, Ben Fanson and Arn Tolsma. Unfortunately it’s not available online.

Black Saturday, ten years on: what’s changed?

The March edition of the VNPA’s Parkwatch magazine is now online, and can be found online here.

The magazine has numerous articles of interest, but we particularly recommend the section where the magazine looks over the Bushfire Royal Commission’s recommendations for action, and assesses how well these recommendations have been followed:

  • Improve community education, the effectiveness of warnings and strategies for safe evacuation.
  • Establish a comprehensive approach to shelter options.
  • Upgrade emergency management, including fire path prediction and the revision of lines of authority.
  • Upgrade the capacity to respond to fire ignitions, including aerial response.
  • Power lines should go underground.
  • There should be a commitment to research and effective action on arsonists.
  • Planning and building controls need strengthening.
  • Improved fuel reduction burning effectiveness.
  • Implementing the recommendations.

For each of these recommendations, the report is mixed: and the magazine concludes as a general comment: ‘The Implementation Monitor for the commission’s recommendations, Neil Comrie, pointed out that the 67 recommendations shouldn’t be considered in isolation. Rather, all identified strategies to protect life (as a priority), infrastructure and the environment should be considered together. Despite its limitations, fuel reduction planning continues, to a large degree, in isolation from other very useful strategic options.

‘And climate change is still the elephant rampaging through the room.’

Central West forests: sorting out what the public thinks

The Victorian Environment Assessment Council has released a summary of responses to its draft recommendations on the Central West forests. The summary can be found here.

The consultation is an interesting example of a public body sounding out opinion as part of its decision making process. In addition to a widely representative reference group, and direct communication with landholders with an interest in the areas in question, VEAC conducted drop in sessions in the region, and invited submissions:

‘In total, 2698 written submissions on the draft proposals paper were received. Approximately 24 percent were from Melbourne, 20 per cent from in or near the investigation area, 19 per cent from other parts of rural and regional Victoria, and 3 per cent from interstate;34 per cent were submitted with no location information. 137 submissions were from organisations and the remainder were from individuals.’

There were 1500 identical [ie, pro forma] submissions. Of these, 919 opposed the creation of a Wombat National Park, and 618 were pro forma submissions prepared by the Victorian National Parks Association. These supported the draft recommendations plus the creation of a national park in the Mount Cole area. The individual submissions reveal a wide variety of often contradictory views, which the council will have to account for in its final recommendations. Some of the submissions showed a degree of cynicism about the Council’s independence, but as far as we can tell, the process has been pretty transparent. Given our own cynicism about aspects of the Victorian Government’s ‘engage Victoria’ process, we were interested in VEAC’s comment on the way it considered the public’s views:

Because submitters do not constitute a representative sample of the population, recommendations are not based on the number of times a comment or viewpoint was submitted; rather, it was what was in the submissions that counted.’

The final report will be delivered to the Minister in June.

Want to be in the Easter bird check?

BirdLife International has identified areas of conservation importance around the world as Key Biodiversity Areas (KBAs). This includes KBAs right here in our region. Our KBAs were designated especially for their importance for two special birds, Diamond Firetail and Swift Parrot, and cover both public and private land.

The three KBAs in the Mount Alexander Shire are Clydesdale-Strangways, Sandon-Strathlea and Muckleford-Newstead.

Sandon State forest: Sandon is one of the key biodiversity areas in our region, along with Clydesdale-Strangways and Muckleford Newstead.

Birdlife’s Easter health check takes an annual snapshot of the threat and conservation actions of the areas that matter most to birds. BirdLife compares results between KBAs across Australia and around the globe. The results are extremely valuable, especially for identifying species decline and targeting conservation work.

BirdLife is looking for local people to complete a 2019 Easter health check for each KBA. To help, Connecting Country is running a workshop on Friday 12 April 2019 in Newstead.   Greg Turner from BirdLife Victoria will talk through the process for our part of the Bendigo Box Ironbark area. Geoff Nevill from the Muckleford Forest Friends Group will also talk about his group’s work in the region.

This annual check is all about assessing habitat and its threats. Anyone with an interest in landscape restoration is most welcome to come along and get involved, whether you’re a beginner or an experienced birdwatcher. Come  to this workshop to learn how you can participate in the Easter Health Check: 

  • Learn about the KBA’s in the Mount Alexander Shire.
  • Find out about KBA Easter Health Check – what it is and how to do it.
  • Meet other people working with KBAs.

Where: Newstead Community Centre Mechanics Hall, 9 Lyons St, Newstead VIC, on Friday 12 April 2019: 9.00 to 11.30 am. It’s free, with morning tea and refreshments provided.

Here’s a pretty picture: tell us how nice it is

FOBIF has made a reluctant submission to the current government consultation on forest management. Our reluctance is based on two concerns:

  1. These consultations increasingly look like popularity polls, along the lines of the Herald Sun’s daily polls on subjects like, ‘Are the young people of today irresponsible?’ In any case, being voluntary, they’re not necessarily a reflection of the community’s views.
  2. The questions in this consultation are either patronising or they try to force respondents into expressing preferences they may not want to express: for example, they ask respondents to ‘prioritise’ ‘conserving plants and animals’ and ‘providing jobs’. This is the old ‘jobs versus the environment’ hoax, and we don’t accept it.

Nevertheless, we had a go. Here is the substance of our submission. The questions are the ones provided by the consultation, and are in italics:

1 How can we protect and improve our forests for all Victorians?

By properly resourcing forest managers, and having them well advised by good research.

2 What benefits do you want future generations to gain or enjoy from Victoria’s forests?

Victorians should be able to benefit from the role of our forests in catchment protection and water supply; they should also be able to enjoy the beauty and biodiversity of our forests. Governments should vigorously pursue plantation timber, to obviate the need to log our native forests.

Fire: another submission

FOBIF has made a late submission to the Bushfire Management consultation [see our previous post], after our representatives attended ‘drop in’ consultations in Castlemaine and Bendigo this month. The substance of our submission is set out below:

  1. The poor quality of the maps supplied for this process, both online and in the hard copies available at the ‘drop in’ sessions, was such that we are unable to comment in detail on the three options offered in this consultation.
  2. We are quite unclear as to the manner in which DELWP will make up its mind about the three options offered. Discussions with your representatives did not clear up this matter:
  3. It’s obvious—we hope—that DELWP could not be running a crude popularity poll, particularly since online consultations like this are not necessarily representative of the public as a whole.
  4. In any case, we do not see that this consultation will add much to the dozens of such consultations which have taken place over the years. We ourselves have attended innumerable meetings and submitted dozens of submissions on the subject of the many fire operations plans developed since the 1990s. We do hope that this consultation will not take place in isolation from those previous efforts.
  5. In the light of the above, we submit that DELWP should take heed of the findings of the Royal Commission Implementation Monitor, and conduct a carefully conceived risk reduction strategy, not dominated by preconceived notions involving scorched earth strategies.
  6. In the light of this, it seems to us that some combination of options B and C might be an appropriate approach to take.

However, as we have repeatedly emphasised over the last 20 years, everything depends on the detail of the implementation:

Burns Hill – a recovering landscape

There was a good turnout for the first FOBIF walk this year despite the hot weather. The 5km trek began at the Chewton Shop and followed Forest Creek to the Monster Meeting site. It was then up Burns Hill with terrific views over the township to the south and along the reef to Trapps Gully before coming back down along the Forest Creek. 

Marie Jones who led the walk has been involved for decades in the revival of the Forest Creek area. She gave an excellent running commentary on the impact of mining and white settlement in the area and the extensive rehabilitation undertaken by the local Landcare group and others. Marie also gave us a rundown of the historical significance of the Monster Meeting site and handed out the newly produced Chewton Domain Society pamphlet, ‘The 1851 Monster Meeting of Diggers at Forest Creek’.

Thanks Marie for leading a wonderful walk which introduced walkers to little unknown trails so important in our history and so close to town.

As explained in an earlier post the April and May FOBIF walks have been swapped. The next walk (21 April) will now be led by Julie Hurley or Rex Odgers starting out from Warburton Bridge. As usual meet at Continuing Ed at 9.30 or at 9.50 at Warburton Bridge, Glenuce.

Another reason to slow down…

Travellers on the Pyrenees Highway east of Newstead will have noticed that work is under way on Vicroads’ wire rope project. A last minute series of meetings between local residents and road engineers has failed to bring any further modification to the project, which will involve significant vegetation removal.

Discussions are ongoing on possible speed reduction changes on this winding stretch of the highway, notable for animal crossings. Vicroads, as in the past, is curiously reluctant to reduce speed limits on its roads. We thought we’d just offer another reason to take the matter more seriously.

The photo below shows an Australian Common Longnecked turtle rescued from the road in Strangways. The mud on the shell suggests that the turtle had just come out of a local dam and was perhaps looking for a better refuge nearer the Loddon.

Australian common longnecked turtle (Chelodina longicollis), Strangways, March 10: these creatures undertake perilous journeys in search of better water body refuges

The Bendigo Field Naturalists’ excellent Frogs and Reptiles of the Bendigo district says of this species, ‘It can live in semi-permanent waterholes and survive summer drought by digging into soil or leaf litter of drying water bodies and aestivating. Alternatively they go in search of a better water body, a behaviour that leads to them being killed on roads and trapped by fences.’

In this case the driver was able to avoid the turtle because he was travelling relatively slowly. As we’ve pointed out before, the animal carnage on our roads is eloquently present in the form of many corpses, most visibly of kangaroos and wallabies. Smaller animals aren’t so obvious, but they are there.

Another reason for slowing down, especially on minor roads.

The remarkable world of wild orchids

Newstead Landcare are delighted to present a talk by Emily Noble on ‘The remarkable world of wild orchids’ at 8.00pm on Thursday 21st March at Newstead Community Centre.

As the Secretary of the Field Naturalists’ Club of Ballarat, Business Manager of the Ballarat Environment Network, Coordinator of the 540ha Clarkesdale Bird Sanctuary in Linton for Birdlife Australia, and proud owner of a bush block south-west of Ballarat that is home to at least fifty different wild orchids, Emily has ample opportunity to pursue her interest in orchids and their interactions with the co-habitants of their environment. Trying to catch these interactions on camera provides her with many unexpected insights into their ecology, helping inform her conservation activities, and providing a source of ongoing wonder.

Come along to learn more about these remarkable plants and their fascinating relationships with their world. All are welcome to Emily’s presentation and supper afterwards. There will be no business meeting to sit through. A gold coin donation would help us cover costs.
