The track was a bit stony and tree-root riddled at the start, but towards the top of the 2km walk the journey was easier to negotiate. There were a few larger rocky outcrops but that did not cause too much effort to pass through. The past fires in late 2019 had left much of the forest blackened with many of the older trees severely damaged as well. However, a lot of the bush was recovering and clumps of fresh eucalypts sprouting out of the sides of the trunks. It lifts the spirit to see this growth after the fire devastation. The grass trees Xanthorrhoea had spouted fresh upright grass-like leaves and many had formed a flowering spike, but alas we were a few weeks short of the prime blooming period and missed out on birds and bugs feeding on the tiny flowers.

Looking around it was hard to imagine that we were standing on what was once an active volcano. The eastern part of this volcano once spread over the Fassifern Valley, Boonah, and even to Ipswich. The western side spread towards Warwick.
The return 2km journey was mostly downhill and quicker than the upward journey. However, there were a few stops to see fauna, at one in particular a male Rose Robin was seen.
The picnic spot soon had a large circle of Field Nats seated around to chat and compare photos, notes and generally socialize. Thanks to all who attended including new members and guests.

Notes on Vegetation and Other Things at Mt Mathieson by the President
Our first outing since the Covid-Crash was a very pleasant affair. Everyone was ready for some fresh air and company. It was good to check-out this particular landscape after the fires late last year.
Cunningham’s Gap area was repeatedly hit by serious bush-fires. Some areas seemed to be totally devastated, with lots of black dead trees, whilst some areas were nice and green with minimal coppicing. Most areas though were blackened, with lots of resprouting going on. Of course, some big trees fell down and some large logs disappeared into a pile of ash.

The burnt understorey was a mass of regenerated weeds mixed with natives. Inkweed (Phytolacca octrandra) was thick and it shows the resilience of weed seeds to remain dormant for decades, waiting for a fire to release them. Silvereyes were having a ball with the quickly ripening fruit – they go from green to black. Another weed (or perhaps a native – some botanists think it is native) was Indian Weed (Sigesbekia orientalis) with tiny yellow flowers. Indigo (Indigofera australis), a native, was prolific and almost ready to start flowering.
The drier areas are dominated by Tallowwood (Eucalyptus Microcorys) and some Yellow Stringybark (E. acmenoides) and the understorey was thick with younger trees. They were all black sticks but resprouting from the base. I did notice a lot of fresh galls on the new branch tips. They were small ball-shaped growths coloured green or white or red. Once again it shows how some organisms (gall wasps or mites) wait a long time, perhaps decades, to go through their lifecycles.

Of particular note were the Grass Trees (Xanthorrhoea latifolia?). They were in flower everywhere. The flower arrangements – comprising a scape (or tall woody stalk good for making temporary walking sticks) and a spike with tiny white flowers – were not very tall. They were in a rush to flower, so didn’t have much time for making tall spikes.
With so much growing going on, insects were still busy and the birds seem to have stayed for winter – they usually leave and come down to my place closer to the coast. Yellow-faced Honeyeaters were common, which is quite unusual.
