Outing Report - Koala Crossing, Flinders Peak, 19 May 2018

Camouflaged Bearded Dragon

On our May outing 21 members from the Fassifern and Queensland Field Naturalists Clubs met at the Queensland Trust for Nature property, Koala Crossing. This property is situated at the base of Mt Flinders, 5km from the township of Peak Crossing. It joins the Flinders-Goolman Reserve and is the largest remaining stretch of open eucalypt forest in the region. Koala Crossing provides an important linkage for koalas in South East Queensland and the property is managed according to national koala recovery action plans.

The property has four different ecosystems, one of which has an ‘endangered’ biodiversity status, and another is ‘of concern’. These ecosystems are able to support a large variety of fauna including the koala, the powerful owl and the brush-tailed rock-wallaby. Not that any of these were seen on the day.

The first walk was on a track that wound its way down to a little dry offshoot of Sandy Creek then curled up to higher ground. The creek is well-named as the sandstone rock of the area weathers into a sandy bed. On the rocky ridges conglomerate rock with quartz was evident and we examined some petrified wood embedded in a type of silt or mudstone. At the top of the ridge we came across a very dozy Bearded Dragon sleeping in the grass.

Lunch was a very social time with talks about the local district, and the koala program by the Queensland Trust for Nature. Almost 100,000 koala fodder trees have been planted since 2015.

Scarlet Jezebel (Delias argenthona)

Later a ridge on the southern section of the property was explored. This had a mixture of Spotted Gum (Corymbia maculata) and Narrow-leaved Ironbark (Eucalyptus crebra) with small stands of Brush Box (Lophostemon confertus) and Moreton Bay Ash (Corymbia tessellaris) interspersed here and there with Bat-wing Coral Tree (Erythrina vespertilio) and Broad-leaved Kurrajong (Brachychiton australis). Here we saw some of the more open woodland bird species, such as Weebill, Speckled Warbler, Jacky Winter and White-throated Honeyeater. There was also both Scarlet and Black Jezebel butterflies in the higher canopy and a couple of Tailed Emperor butterflies rushed through hardly giving us time to identify them.

Tailed Emperor (Charaxes sempronius)

Overall 42 species of birds were recorded on the day, including the Speckled Warbler which is not often seen as it usually forages very quietly in the leaf litter. It is well camouflaged too, being brown and cream with dark brown stripes and streaks. Surprisingly for the time of year 16 species of butterfly were recorded. The Long-tailed Pea-blue being one of the more cryptic ones in the grass.

Some Grasses: Threeawn Speargrass (Aristida vagans). This grass likes eucalyptus communities on rocky and sandy soils. Flowering and fruiting all year.

Pitted Bluegrass (Bothriochlaoa decipiens). Prefers low fertility soils receiving above 500mm annual rainfall.

Barbed Wire Grass (Cymbopogon refractus). A grass native to eastern Australia, widespread and common, prefers lighter, poorer soils. The leaves give off a spicy, lemon-ginger smell when crushed. Habitat for small mammals and frogs. The seeds are eaten by rosellas.

Black Speargrass (Heteropogon contortus). A tropical, perennial tussock grass and a valuable pasture species across much of its range however it has also been responsible for the elimination of the wool industry over much of Australia due to the seeds becoming embedded in the wool and skin of sheep, devaluing the wool and killing the animals. Also troublesome in the socks and skin of bushwalkers.

Slender Rat's Tail Grass (Sporobolus elongatus). Found in higher rainfall areas it is more common on lighter, well-drained soils. In drier areas, it is more common along sandy creek-lines or on heavy clays of the plains.

Outing Report - "Bindarrabi" Camp, Koreelah NSW, 20-22 April 2018

It was an enthusiastic band of campers and day-trippers who met at a favourite spot for our annual April camp. Showers a couple of days prior brought out a variety of fungi, brightened the mossy rocks to a brilliant green, and adorned the lacy grey-green lichen covering the tree trunks with tiny drops of moisture. The banks beside the track down to the creek pools were lush with maidenhair ferns and large arching branches of the soft bracken Calochlaena dubia. Tiny terrestrial orchids were observed and photographed. 

 One of the walks was to the top of Koreelah Gorge with its picturesque scenery and nearby heath vegetation.

Another walk was along the Grey Gum Track. The flora members were kept busy identifying the trees, understory and wildflowers.  Colonies of the lovely mauve flowers of one of the Plectranthus mixed with bright yellow Bulbine vagans drew our attention. A frog was disturbed amongst the litter on the trail and was photographed and identified as a Great Barred Frog.

The orchid enthusiasts found and photographed a number of the tiny terrestrial orchids but not all were as easy to see.

The wonderful camp facilities - bell tents for those who did not have their own accommodation, (the upper class in the club opted for this), the large, well set up camp kitchen, hot showers and clean eco toilets as well as the variety of habitats and wonderful scenery on this property, and good company  – made for a very comfortable and enjoyable few days.
