Report on Kalimna walk Sunday 16th August

It seemed that everyone who turned up for our FOBIF walk today commented on how beautiful the day was – glorious Central Victorian sunshine and a BOM promise of 17O. So it was a happy crowd who gathered in Kalimna Park for a short walk to explore and enjoy getting to know the Castlemaine bush better; to hone in on our observation skills of the bush around us – from the details of plants to the broader landscape.

Our guides, Chrissi and Frances, led us to three slightly off-road sites where ecological surveys had been conducted in 2019. At the first site we looked down and explored the bush floor, looking for plants we didn’t know or which just interested us. Chrissi introduced us to a wide range of reference material to aid our exploration and become familiar with the plants. We discussed the difference between Hovea and Hardenbergia, marveled at the mosses and lichens and tried to avoid treading on the abundant chocolate lilies from which, hopefully in a couple of months will provide an explosion of scent and colour. And still the sun shone….

At our second stop Frances gave us suggestions to help understand eucalypts, especially Red Box, Grey Box and Long-leaved box, by looking up at the foliage as well as wandering round the trunks to pick up leaves and buds for identification. Meanwhile a Scarlet Robin flitted amongst the branches keeping an eye on us. Generous discussions ensued about birds and plants and ecological influences.  And still the sun shone…

A broader landscape view of the bush was the focus of our last site. Chrissi invited us to think about the influence of such things as slope, aspect, vegetation layers and provoked us to question what might be the relationships between them. Such questions can increase our understanding of the bush we see and add to our enjoyment.

As we gradually wandered back to the cars the sun was still shining and it was wonderful to see the bush starting to bloom.  We should now be more attuned to the bush we love to explore on foot. Thank you, Chrissi and Frances for sharing your knowledge. And thanks to the sunshine – a perfect day for being introduced to the emerging Spring around Castlemaine.

Walk and plant identification session – this Sunday 16th August at Kalimna Park  

Whether you are new to the area or new to ecology, this walk is all about where to begin, what to look out for and how to grow your knowledge of local plants and ecological processes in the Castlemaine region. Over a stroll through Kalimna Park, local ecologists Chrissi Charles  and Frances Cincotta will teach you how to begin to identify native plants, discuss some of the ecological processes for why plants grow where they grow, and share some of the digital and analogue tools that are readily available to help you learn more about the native botanical world around you. Please bring along any plant identification books if you would like to use them – we will also bring some to share. 

For inquiries please contact: Chrissi Charles 0433 718 246

Meet at Community House at 9.30am. Alternatively, you can meet at 9.40am on the Kalimna Road: https://maps.app.goo.gl/WEMPK8ceQTGn7cVj6

Second report on the Tarilta Creek walk, 21 July 2026

Chris Green has sent a report on FOBIF’s Tarilta Creek walk. We thought we would post this as well as the previous Tarilta Creek report especially as Chris has included some terrific photos. 

A Foray into Tarilta Creek

Eight intrepid walkers, led by Jeremy Holland braved a frosty Castlemaine morning and made our way through sunny clear-air to our start point on Sawpit Track 2.5kms NE of Lalgambuk (Mount Franklin).

The walk was a 14km circuit initially heading NE along a section of the Goldfields Trail through ridgetop woodland. We then traversed nor-westerly, via moss floored tributary valleys with numerous clearwater filled pools and glistening waterfalls, finally reaching the substantial Tarilta Creek. This creek has beautiful grassy flood-plain clearings and large trees. We followed beautiful Tarilta Creek upstream for about 4 kms, involving many interesting slippery creek crossings. As the creek became narrower, with more exposed bedrock our path required negotiation of steep scree slopes and occasional fallen trees. The circuit was completed via vehicle tracks over shallowly undulating country through open woodland to our cars.

The highlights of the walk were many, and included:

  •  The verdant moss-filled gullies, peppered with gems of fungi everywhere.
  • Tarilta Falls with its amazing display of anticlinal structure and deeply sculptured cave formations.
  • The abundant crystal, clear water holes and streams, a legacy of recent flooding.
    The tranquil grassy floodplain-clearings along Tarilta Creek with giant gum trees, some maybe a 100 years old.

We noticed:

  •  the almost complete absence of historic gold mining activities;
  •  overgrown, historic access tracks probably made by timber cutters decades ago;
  •  the increasing gorse, as we approached the headwaters of Tarilta creek;
  •  and the deeply incised central channel with in the Tarilta Creek floodplain (probably an adjustment to the landform within the last 200 years).

An overlay, on this walk was being witness to a large-scale ground-hugging mist phenomena.

We had noticed from the highest point lookout along the walk, a strange dense mist to the NW, seemingly near Lake Cairn Curran.

On our return drive home looking west from the northern slopes of Mt Franklin we saw a strange looking ground-hugging cloud formation.

On approaching Guildford we became swallowed up by a dense mist sitting in the low lying Loddon River valley floor. The air became clear again on approaching Castlemaine. But a few minutes later, Castlemaine became engulfed in the same dense mist.

 

Inspired to see this mist from above, the writer headed for summit of Mount Tarrengower near Maldon at sunset to witness an amazing site.

A lake of choppy white cloud spread across the landscape with areas of higher ground rising as dark silhouettes.

Short walk on Mt Tarrengower (or Dharrang Gawa) report by Liz Martin

A large group set out from the side of Mt Tarrengower on a chilly, but sunny day yesterday for FOBIF’s annual ‘short walk’.  Bernard and Deirdre Slattery led the walk ably assisted by our experts, including Christine Henderson on geology, Frances Cincotta on plants and Joy Clusker on fungi.

We set out to look at the geological history of Mt Tarrengower. The rock caps consisting of the hornfels rocks were abundant around the top area but the granite rocks that rose as magma appeared lower down.  We had several terrific viewpoints as we wandered around the contours of the mountain looking out to misty ranges and we could see as far as Mount Macedon. 

The research about the geology came from the book Six Peaks Speak by Barry Golding and Clive Willman. 

Dharrang Gawa‘s geological makeup has given it two different faces revealed by walking either side of the summit. Large granite boulders are predominant on the way up , but then you encounter dense rocks called hornfels.  The huge area of the Harcourt Batholith includes Mt Alexander and was formed when the magma was hot.  Once the magma rose it baked the surrounding sandstone and mudstone and this metamorphosed the rocks above into hornfels.”   We were able to clearly identify the difference between the granite and the hornfels. 

“The hornfels were hard and used to create stone tools by Dja Dja Wurrung and also formed part of Maldon’s building history being used in gutters and buildings including the Maldon Holy Trinity Church.” 

We also found lots of fungi and some lovely striped greenhoods in amongst the rock ferns. These three photos were taken by Joy Clusker and are left to right: Large-striped Greenhood, Earthstars and Belly Buttons.

Early wildflowers were blooming including Early Nancy and Rice Flowers. The eucalypts were mostly Long-leaf Box, Grey Box and Yellow Box. 

Some players from the women’s footy team, the Castlemaine Falcons, joined us.  Thanks to everyone who added to our local knowledge of the geology and natural features of Mt Tarrengower. A very enjoyable walk of 3 kilometers with time to look at the small plants and fungi while identifying the granite and the hornfels, and even do a little weeding!

Tarilta Creek Walk Report by Ros Woodburn, 19 July 2026

What a glorious, still, blue Winter ‘s day. A huge thank you to Jeremy Holland, our fearless leader of total 8 walkers for 14km: up and down the tightly knit hills and gullies, along roads, a part of the Goldfields Track, over rocks, around fallen logs, along mossy emerald waterlines (minor tributaries of Tarilta Creek), a bit of gorse, waterfalls x2, and then finally lots of zig-zagging across and upstream on Tarilta creek … yep – approximately 10+ crossings. All so varied in such a small geographic area. Some parts with green golf course like openings beside the trickling waters under stately, up to 40m tall candlebarks and stringybarks. (Not to mention the “glorious” golden gorse specimen shrubs as we rounded the snub of a ridge from shadow to sunshine later in the afternoon. And yes, some less “glorious” gorse in thickets further upstream along a section of the now steeply sided Tarilta Creek).

The group chatter was varied (only a touch of politics) and usually gently humming as our group meandered (… stumbled???). Geology was always stirring bewilderment from the initially quite white sandy track to rocky lichen covered steep slopes to the vertical break in a watercourse allowing clear viewing of an anticlinal folding. There was a wide variety of wattle species, many of the birds mainly identified by their calls and such beautiful flashes of colour in the fungi – oh so magical in the gentle grey of the rich Box-Ironbark Forest.
