Get in on the ground storey

Posted on 29 August, 2022 by fobif

Interested in digging a bit deeper into the ‘problem’ of leaf litter?

Remember: it’s the stuff which is a fire risk, and should be cleaned up…or it’s the stuff which keeps moisture in the soil, and prevents erosion…or maybe it’s both?

You might want to delve into this question by checking out The Ground Storey, a little book published by Goulburn Broken CMA. You can find it online here.

The book is directed at property owners, and has practical info on the importance of leaf litter for biodiversity–and how to manage it to reduce fire risk.

In Sebastopol Gully: that stuff lying on the ground isn’t rubbish. It’s biodiversity heaven.

Interestingly, the book takes up the challenge put by the NSW Threatened Species Scientific Committee:

‘Clearing of leaf litter and fallen logs, often associated with clearing and/or burning of the understorey for clearing, removes habitat for a wide variety of vertebrates and invertebrates which live in the leaf litter and in the fallen logs – including reptiles, small mammals, invertebrates, for example, spiders, molluscs, millipedes, ants etc. These impacts may affect ecological functioning. Loss of the leaf litter also exposes bare soil which will be susceptible to soil erosion and drying, and hence affects the soil biota, and may make sites more vulnerable to weed invasion.’

In other words, leaf litter has a value: it should not be thoughtlessly removed. The Goulburn-Broken book carries some eloquent info on this theme.

And the fire risk? Check chapter 7 in the book.

Water and wattle

Posted on 26 August, 2022 by fobif

Despite the damp weather lately it is rather nice out in the bush if you like water or wattle or preferably both.

The photos are around Tarilta Creek and the two well known and lesser known falls there which are usually dry, taken last Tuesday (23rd August).

A stroll through the Metcalfe NCR

Posted on 22 August, 2022 by fobif

Good numbers rocked up for FOBIF’s August walk through the Metalfe Nature Conservation Reserve yesterday. This small reserve features beautiful open valleys of grassy woodland, the understorey dominated by Wallaby Grass.

Part of FOBIF’s walking group in the reserve, which features quiet open grassy valleys.

The reserve, unusually for this region, carries no Stringybarks, giving it quite a distinctive appearance, especially given the large number of unusually old Long-leaf Box eucalypts. Leaders Barb Guerin and Lionel Jenkins organised a stimulating route through some idyllic valleys before ending in a stroll along the high ridge which bisects the reserve, with glimpses of fine views across to the west. They also cleverly arranged excellent walking weather, brisk with great patches of bright sunshine. There’s an abundance of Hovea in flower, and although the fungi season is ‘over’, there was enough around to keep the eyes to the ground.

Our thanks to Barb and Lionel for a great stroll through a perhaps under appreciated gem of a reserve. Next month’s walk is in the Muckleford forest. Check the program for details.

Signs of the ancient and dynamic Earth

Posted on 22 August, 2022 by fobif

Photo1: The once horizontal sandstone layers are now almost vertical – folded and tilted by shifting tectonic plates.

The mysterious sandstone layers of Castlemaine and Chewton are one of the most defining characteristics of the local bush. Like the bones of some ancient earthly animal, they form a pattern of upstanding ribs that hold clues to the land’s long evolution. Under a microscope, the sandstone is made up of untold billions of sand grains, and many have the distinctive features of grains derived from a granitic terrain – most probably the ancient Gondwanan mountains that rose to our west some 480 million years ago. The mountains were weathered down and rivers carried grain after grain to the ocean floor further east, showing us recycling is nothing new!

Having survived that little trauma, the grains remained happily undisturbed for 40 million years in their ocean floor beds. Then suddenly they were subjected to the relentless forces of plate tectonics. All the layers were squashed between the ancient Gondwana continent margin and the palaeo-Pacific tectonic plate to the east. These forces just happened to be east-west and so all the folded layers now run north-south forming a handy visual compass for our ramblings in the bush.

The sandstones of the bush might look ancient and immovable but they remind us of our dynamic Earth and the constant recycling of, well, everything!

Photo 2: The sandstone is stained by iron-bearing minerals and is cut by cracks, called joints

Here’s an answer–Oh…but what was the question?

Posted on 22 August, 2022 by fobif

FOBIF has received an answer from Forest Fire Management to its submission on current plans for management burns in this area.

We print the answer in full below. You can check to see if it answers any of the questions in our submission.We don’t believe it does.

This kind of exchange, or non-exchange, is an example of one of the problems of ‘consultation’: questions are asked, answers are given…but there doesn’t seem to be any connection between the two.

Part of the problem is that we, and other concerned groups, keep asking questions about specific places: and we want specific answers to these questions. Either the Department doesn’t have the answers, or the officers don’t actually have the time to pay attention to each submission. The result casts doubt on the value of the ‘consultation’ process.

Looking north from the Wewak Track, August 2022: the dark green is carpets of Matted Bush-pea. Is it a high fire risk? The area is slated for ‘fuel reduction’, but it seems impossible to get details through the consultation process as to how the burn will be managed.

Readers can judge for themselves. Here’s the DELWP response to our submission:

‘Thank you for your letter explaining your concerns regarding fuel reduction burns listed on the Loddon Mallee Joint Fuel Management Program (JFMP) 2022/23-2024/25.

‘Strategic Fuel Breaks (SFB) work together with our zoning by establishing areas of reduced fuel that support planned burn operations to be conducted adjacently. The SFB program has been developed in conjunction with our planned burning program.

‘We carry out a range of on-ground preparation works before the burn to ensure that the planned area is safe to ignite when the conditions are right. Planned burn preparation is essential for the safety of fire crews and the community. Preparation works may include raking around trees to protect habitat trees, removing hazardous trees to make the burn safer for fire crews, grading the existing roads and tracks to improve access and reduce the risk of the burn escaping. We’ll adjust ignition and monitor fire behaviour to meet appropriate burn objectives, which is supported by the advancements in weather forecast products, burn prescriptions and smoke modelling.

‘Forest Fire Management Victoria (FFMV) continues to collect fuel hazard data pre and post burn for a selection of our high priority burns in the Asset Protection (APZ) and Bushfire Moderation (BMZ) Fire Management Zones, covering at least 20 per cent of burns. We collect this information as part of our tracking of progress toward strategy implementation and into inform our understanding of fuel recovery rates. For example, we have also used this fuel hazard data, collected over many years in Box-Ironbark forests, to update our fuel models used for decision making.

‘As part of the Victorian Bushfire Monitoring Program, FFMV is working to improve our specific understanding of fire effects on the environment – this includes both planned burning and bushfire. In the Box-Ironbark forests, there is a statewide project that the Department of Environment, Land, Water and Planning has contracted the University of Melbourne to undertake through the Bushfire Hazards Cooperative Research Centre. This work commenced early in 2021.

‘We look forward to future constructive collaborations with the Castlemaine community and encourage you to continue to share data and your concerns with us as we endeavour to find the balance between protection of communities and the environment from bushfire.

Yours sincerely’

Reminder about FOBIF AGM on 12 September

Posted on 15 August, 2022 by fobif

As outlined in a previous post, the FOBIF AGM will be held in the Ray Bradfield Room on 12 September beginning at 7.30. After a short time for AGM formalities Patrick Kavanagh will deliver on talk on Photographing Nature. Patrick has contributed to all of our FOBIF photography shows. He describes his interest in photograph in the following words:

I live in the woodlands of Central Victoria, where I am so often amazed and moved by the natural wonders that surround me. The vastness of the night sky, the magic of a small bird safe to come so close, the other-worldly grace of an insect, the purity of refraction in a dew drop on a moss. With my camera, I try to hold onto some of these extraordinary glimpses and to share them.

FOBIF’s walks guide: an update!

Posted on 8 August, 2022 by fobif

Parks Victoria is currently undertaking landscaping works around the Garfield Wheel in the Castlemaine Diggings NHP. These have changed the nature of the signage in the area, and therefore affect the directions we have given for Walk 8 in our book, 20 walks in the Mount Alexander region.

New landscaping around the Garfield Wheel foundations: though unfinished, they’re already an improvement to the precinct…and will be even better if they eliminate weeds in the area.

As at August 7, the directions to proceed from the wheel towards the Welsh Village in this walk are as follows: take your bearings from the Goldfields Track sign (pictured). Walk forward (direction Castlemaine) about a hundred metres to the yellow topped walk post. Disregard it, and take the track about 10 metres to its right, currently marked by dark posts, with no signage. This is the Dirty Dicks track. It takes you past various mining works, and is marked by grey posts.

As the works around the wheel and on Dirty Dick’s track are completed, we are assuming that this track away from the wheel will be more clearly signposted.

The works around the Wheel are part of a project to improve access to the Welsh Village. So far, they’re looking good. We have hopes that before they’re finished, Parks will have eliminated the Bridal Creeper infestations in the precinct.
