A walk in any weather

No, the Mount Tarrengower walk on Sunday wasn’t cancelled!

Instead of huddling at home, FOBIF walkers had the pleasure of seeing the bush in its quiet, misty late-winter mood. In the soft light we saw the bright green resurrected mosses, the richly blue-grey lichens, and many tiny signs of spring coming soon. Early Nancies are flowering, many lilies are about to burst into flower, and several wattle species are covered in fattening buds: Golden, Varnish and Black Wattles amongst them.

Spring is coming, and Early Nancies are telling us so.

From the camp area, we walked off track on a contour around the north-western flank of the Mount.  Between the large granite slabs and tors, we saw several shrubs: the delicate green flowering tubes of the rock correa, Correa glabra, the white-flowered Pimelea linifolia and the Flat-leaf bush pea, Pultenaea platyphylla. Frances Cincotta added to our appreciation with succinct pointers for recognising the different shrubs and several Eucalypt species.

Further on we found several rock wells on the granite slopes: a great educational reminder from the First People of Mount Tarrengower about water and its necessity in our dry climate.

Frances Cincotta gestures hypnotically: it helps to have a guide, especially to the rare plants.

We didn’t need the big view from the Fire Tower. The lack of cars and the shifting misty light on a perfect Cherry Ballart were rewards enough for the climb to the summit.

Getting things into perspective: Aboriginal rock well on Tarrengower.

Thanks to Gen Blades and Lisa Hall for their leadership, Frances for her knowledge and several amateur geologist participants for sharing their interest in the granite and the hornfels.

Next month’s walk is a detailed look at Kalimna Park. Check the website for details.

Listen while you walk . . .

As part of the new Campbells Creek missing link project, Rob Law from Friends of Campbells Creek has created a ‘soundtrail’. It starts at the Forest Street entrance to the walk and continues through to the end at the Campbells Creek playground.

Living alongside the creek, Rob has noticed that since the missing link of the track was opened, there has been an increase in use. The increase has been at least a 600 per cent. The accompanying soundtrail was launched a couple of months ago and already scores of people are downloading and listening to it along the trail. Relevant signage along the creek is coming shortly.

Map showing the walk and where the recordings are triggered.

The technology used is a phone app called ‘soundtrails’ that you can download. As you walk along the trail, the app uses GPS to trigger the audio on your phone. Walkers can listen to stories about the creek, its ecology, history and values, as well sounds of nature from different times of day and spread throughout the year.

To operate the app, visit soundtrails.com.au/campbells-creek and download the app from the Apple Store or Google Play. You will need to use headphones. Once you are at either end of the track, just open the app.

“The goal of this project is to invite people down there to spend some time, getting to know it, slowing down and listening more deeply, rather than just passing through for exercise, because it’s much more than that. Through doing this project, I uncovered all of these amazing people who live here, who have some knowledge of the creek that is specific. There are a range of different perspectives as well, from children through to people that have been here their whole lives and are in their 80s, which gives that sense of how the place changes over time as well.

I’ve been down there a lot with my kids and their friends and spending time in their world and watching how for them, they are already very immersed in it, and we kind of have this separation, but they are very much in the place. I think that’s important for adults to think about how we relearn that, there is no boundary for them between their imaginative world and what we call the real world. Being able to tap into that sense of wonder that they have and we forget about as we become adults.”
(Rob Law quoted in the Midland Express 3/7/2025)

In a two minute recording on the app seven year old Ralph Maguire-Law explains the life cycle of the red eye cicadas that live along the creek.

Bizarre, weird, unbearable, impossible, obviously unacceptable…but true

Ever been irritated by the rubbish dumping thing? Of course, most people are—and most people wonder: what kind of person would dump rubbish in beautiful places like our bushlands?

But there’s another dimension to this problem: it starts at the source.

Plastic dominated rubbish pile at the Railway dam a few years ago. FOBIF has an extensive collection of photos of similar rubbish all over our region. Of course, dumpers are to blame, but the real problem starts at the production point.

Here are some fun facts: in 1950, the world produced 2 million tonnes of plastic. In 2022, the figure was 475 million tonnes; at present rates of increase, it will top 1000 million tonnes by 2060.

As if these figures weren’t bad enough, consider this: of the above quantities, 9% is recycled, about 50% ends in landfill, 19% is incinerated…and 22% slops around the planet, most dangerously in the oceans: it’s been estimated that 15 tonnes of plastic is dumped in the sea every minute!

And, of course, it’s hard not to notice that a large part of the stuff dumped in our bush is plastic.

How can such insanity persist? Guess what: it’s because plastic is ‘cheaper’ than alternative substances! And convenient, of course. If you have the stomach for some terrifying stats about Australia’s plastic use, check here.

There’s a UN conference in Geneva right now to try to hammer out a treaty to limit plastic damage: for more details check here.

And if you want to sign a Greenpeace petition urging Australia to commit to such a treaty, check here.

Write a letter to our politicians

Wombat Forest Care have had success writing to politicians about Victorian Environmental Assesment Council (VEAC) matters. They have started a letter writing campaign to prompt the government to legislate the Central West Parks without delay.

Can you write to Maree Edwards, The Hon. Steve Dimipoilos and The Hon Jacinta Allan to legislate Mt Cole-Pyrenees and Wellsford Forests immediately, as recommended by VEAC?

These forests contain important plant and animal commumnities. According to VEAC, the variety of vegetation types in the Mount Cole–Pyrenees block provide habitat for a high diversity of flora and fauna, with 51 rare or threatened plants and 48 threatened animal species having been recorded here. Seventeen species that are part of the threatened Victorian temperate woodland bird community have been recorded in this block.

The Wellsford block provides habitat for a high diversity of flora and fauna including 32 rare or threatened species and a further seven members of the threatened woodland bird community.

Please email-

A walk in history: Malmsbury Coliban Channel.

It was a welcome sunny day for an enjoyable and interesting walk along section of the
Coliban channel near Malmsbury. Author of the book, The Coliban Main Channel: A Walking Guide, Stephen Charman, shared details from his extensive historical research &  love of walking. The walk focused on the Malmsbury section of the seventy kilometre long channel, which goes from Malmsbury reservoir to Crusoe Reservoir in Bendigo. We set off from Malmsbury Reservoir Picnic Ground and followed the main channel, where Stephen pointed out features of the infrastructure of the channel, both past and present. We observed remains of diversion channels, a story of how overflow from a slaughterhouse was managed by a wooden bridge, now concrete,so that the contaminated water did not flow into the channel. The Coliban River was often in proximity and the sight and sound of running water near Ellis falls was a lovely spot to stop for some morning tea. The walk was a glimpse into the movement of water across this dry landscape over the past two hundred years. Looking at this huge piece of infrastructure raises many issues that relate to the impact of our manipulation of the landscape.

Nothing to see here…Hang on!

If you’re crossing the Forest Street footbridge over Campbells Creek this month, you might want to cast your eye down to the downstream edge of the bridge. Those nondescript streaks of shades of green are colonies of three different moss species. The remarkable thing about this apparently ordinary scene is that council staff regularly come along here and scrape the moss off…and regularly it comes back, colonising an apparently inhospitable concrete surface. In its way, it’s a kind of heroism.

Council versus moss, now in its umpteenth season: Silver Moss and Cushion Moss regrowing after repeated removals…

The grey green moss is Bryum argenteum (Silver Moss). It’s common in Castlemaine streets, and is found on every continent on earth, including Antarctica. In a few weeks it will produce some picturesque spore capsules—but you’ll have to get down on your knees to see them properly. The deeper green is Grimmia pulvinata (Cushion Moss). It’s found from Siberia to the southern regions of Chile. Its spore heads are visible already.

Grimmia pulvinata with new spore capsules, Campbells Creek footbridge: it doesn’t matter how often it’s scraped off, it comes back as good as ever.

FOBIF’s field guide, Mosses of dry forests in south eastern Australia, has just been reprinted in a revised edition, including for the first time common names to go with those ferocious scientific tags. This guide, produced as an experiment in 2014, has proved tenaciously popular, and has now gone through 6 reprints.
