Outing Report October 2020: "Highwoods" East Jimbour

 Over several years now I have had the privilege of visiting a property owned by my good friends Martin and Karen Ambrose from Dalby. It is a great spot for the natural historian and is situated off Loves Road, East Jimbour in the southern section of the Brigalow Belt Bioregion. This bioregion holds a good number of Queensland’s rare and threated species of flora and fauna and has been greatly impacted since white colonis-ation, as it also contains extensive areas of deep, black cracking clay soils ideal for crop growing and the pastoral industry. As one local farmer once put it to me, “the soil here (on the Darling Downs) is so rich you could eat it with a spoon”. The Ambrose property is about 10 minutes’ drive from the small township of Jimbour and Jimbour House from whence the Prussian explorer Ludwig Leichhardt commenced his ill-fated journey to the Gulf in 1848.

Martin and Karen purchased the property towards the end of 2012 and named it “Highwoods” after a farm once owned by Karen’s parents in East Sussex in England. The area of the Ambrose property, part of a larger subdiv-ided block, is 77 hectares (188 acres). The main attraction that clinched the deal was the extent of remaining dry bottle tree scrub and the number of magnificent specimens of Queensland Bottle Tree Brachychiton rupes-tris remaining on the property. The Ambrose family are keen conservations and environmentalists and, as well, Martin was keen to try his hand at raising a few head of beef cattle to carry him into his retirement post QPWS. To these ends they have carried out extensive improvements to the property’s infrastructure including the fencing off of areas of remnant scrub and dams to exclude cattle and for the preservation of the local fauna and flora. At any one time, depending on the vagaries of the cattle market and climate, Martin runs about 20-35 Angus steers purchased at about 180kgs and marketed around 330kgs. They are run for about eight months on mainly couch and Rhodes Grass, also Green Panic and Buffel Grass waxing and waning depending on season. Bottle tree scrub occupies about 25% of “Highwoods”. African Boxthorn and feral Pigs are the major pest species on the property.

Fellow TFN member Mark Weaver and I met the main contingent of Field Nats in Jimbour on the morning of the outing around 9.15am after which we took the short drive to “Highwoods” to commence what proved to be very enjoyable day in good company. Martin has been assiduous in maintaining a list of the fauna on his property since moving there and now, after Trish and Lisa’s efforts, has an embryonic flora list to grow. The list now stands at 174 vertebrate species with the main taxon being birds (129 species), 151 invertebrate species with moths and butterflies being their main representatives at 119 species due to Wesley Jenkinson’s efforts. Aside to a few weeds and a couple of ferns the flora list stands at 50 thanks to Trish and Lisa. A list of the birds, plants and most of the invertebrates seen on this day will be appended to this report as composed by Ben, Trish and Glenda, respectively.

A few of the highlights of our day worth a mention include our flushing of an Eastern Barn Owl during our morning walk that. Unfortunately it disappeared into a hollow bough before we could indulge ourselves with a good look. The other bird of the day was a single Diamond Dove seen on the shore of one of the property’s dams. Martin had seen this bird in the same location a few days before and it was a new species for the property list. Fortunately, everyone got a good look, and some took photographs of this bird. This same dam is one that Martin has excluded his stock from and is a haven for wildlife. The water is clear, and you can easily see the Curly Pondweed in its depths with its surface presently covered in the pretty flowering Swamp Lily (Water Poppy) and the yellow-flowered Water Primrose. I’m particularly attracted to this dam, as it’s the haunt for a few favourites of mine, the Red-bellied Black Snake and Plum-headed Fiches although, sadly, none were seen on this day. We did, however, record a good number of odonates here, which is another mob I’m enamoured to. We recorded 10 species comprising the damselflies Red and Blue Damsel, Wandering Ringtail, Aurora Bluetail, Common Bluetail and Eastern Billabongfly plus the dragonflies Australian Emperor, Blue Skimmer, Scarlet Percher, Wandering Percher and Common Glider. The Wandering Ringtail and Eastern Billabongfly were new for the property list as was the Eastern Sedgefrog recorded by Robert Ashdown at this dam. Another “new” invertebrate found on the day was the exotic dung beetle, the Grey Dungball Roller Sisyphus spinipes, native to Central and Eastern Africa that was imported during CSIRO’s extraordinarily successful dung beetle programme. Whilst Australia’s dung beetles generally bury their breeding boluses, that can be of various configurations, the Grey Dungball Roller follows in the tradition of the Sacred Scarab Scarabaeus sacer associated in Egyptian mythology with the divine manifestation of the Sun God, Khepri. These ancients saw in this beetle’s trundling of its round dungball a direct association with Khepri’s rolling of the sun across the sky. The Grey Dungball Roller’s beautifully spherical dungballs are quite common on “Highwoods” stashed on the surface under grass tussocks, along edges of logs etc.

After our morning’s walk we retired to the Warden’s cottage for lunch. The resurrection and restoration of this cottage has been one of Martin’s main innovations. It was originally constructed in Edward Street in Dalby by the Red Cross where cooked meals were prepared for the homeless and disadvantaged. Later it was moved to Jimbour in a failed attempt to establish a bed and breakfast behind the local store and where it gradually fell into disrepair. Martin purchased it for $1000 and moved it to “Highwoods” and has restored it to its former glory. The outhouse arrived by a similar circuitous route rescued from oblivion on an abandoned homestead site near Moonie. It, too, has been restored to its former glory – if an outback dunnie can be considered in any way glorious? After lunch some of us headed off on another walk whilst others remained at the cottage, as it was now getting quite hot. The afternoon was mainly passed in botanising and Trish would be far more qualified in commenting on the highlights of this aspect of our outing. If I can be so bold, I do remember her getting quite enthused about a tree that she eventually confirmed as the Rose (Crow’s) Apple

Owenia venosa. More than that is beyond my very limited botanical knowledge to relate. I do like plants though, despite what might appear my cavalier attitude here. After we returned from this walk the shadows were lengthening but everyone seemed to have enjoyed the day and there are plans in the offing for a return in the late summer/autumn of the New Year with the option of a campout. Looking forward to that already.

Invertebrates at Jimbour (by Glenda Walter)

Due to the dry weather, not many invertebrates were found on “Highwoods”, the property of Martin and Karen Ambrose at Jimbour. However, I’m sure this will change as soon as rain falls in the area. I photographed three species of ants, two of which were identified by users of the iNaturalist website. A small nest of a species in the genus Meranoplus were found under a dead log. Their common name is “Cautious ants”, appropriate as they moved slowly about, quietly shifting their pupae when disturbed. This was in contrast to the ants in the genus Campon-otus, also identified by an iNaturalist user, which tripped over each other, dashing madly in all directions when I invaded their rock shelter.

Three leaf beetles were found, family Chrysomelidae. Calomela pubiceps is an attractive green beetle which was found on an Acacia tree and for which there are few records; it was identified by Martin Lagerwey, Leaf Beetle expert. A second leaf beetle was identified only to tribe level, Luperini, in the Galerucinae subfamily, also by an iNaturalist user. Many leaf beetles feed only on specific plants, but I was unable to recognise the vegetation on which this one was seen.

Mantids have recently hatched, and the three I saw were tiny nymphs. The burying Mantis, Sphodropoda tristis, when very young curls the abdomen up over its back. It is so named for the female’s habit of burying her eggs in soil or leaf litter. Diana Ball spotted a large and colourful paper wasp, Polistes stigma townsvillensis which was untypically crawling on the ground near our feet while we lunched.

Fourteen spider species were photographed, but many were tiny juveniles. Diane Pagel found several nests of tiny black-spotted pink spiders, recently hatched but too small to identify. Anastasia saw a very small spider egg sac hanging from a fence. This was identified from a Field Guide as belonging to a small orb weaver, Argyrodes alannae. A female of this species was found in the bushes nearby. Anastasia also found a large female spider, Trichonephila plumipes, suspended in her golden web between trees.

Bird list: “Highwoods”, East Jimbour, Sunday 04 October

Despite our early start, about 20 attendees assembled at Jimbour, where Rod Hobson and Mark Weaver met us, to lead us to Martin and Karen Ambrose’s property 10 kilometers to the north-east. Here, Martin and Robert Ashdown were waiting. [These four had spent the previous day on the property, and, bird-wise, they achieved a tally of mid-50s of sightings. So, we had a target for our fine weather, if somewhat breezy, day ahead.]

As we turned into Love Rd (the property’s access road), a Sulphur-crested Cockatoo head, crest excitedly displayed, popped out of a hollow in a roadside tree, as if registering disapproval of this early morning intrusion by our procession of eleven vehicles, thereby interrupting its Sunday morning sleep-in. Once past our much-put-out cockatoo, our day produced a further 34 species on the property (a little short of our aspirational target set the previous day).

Welcome Swallow, Tree Martin, Rainbow Bee-eater, Noisy Miner, Apostlebird, Noisy Friarbird, Striped Honeyeater, Spiny-cheeked Honeyeater, Brown Honeyeater, Yellow-faced Honeyeater, Striated Pardalote, Olive-backed Oriole,

Crested Pigeon, Diamond Dove, Yellow-rumped Thornbill, Little Yellow Thornbill, Superb Fairy Wren, Variegated Fairy Wren, Willy Wagtail, Magpie Lark, Double-barred Finch, Red-tailed Black Cockatoo, Galah, Pale-headed Rosella, Little Corella, Black-shouldered Kite, Grey Butcherbird, Pied Butcherbird, Barn Owl, Wedge-tailed Eagle, Channel-billed Cuckoo, Australian Raven, Crow (unknown species), Australasian Grebe (nest & well-grown baby).

October Speaker Report: USQ Associate Professor John Dearnaley on the topic “Mycorrhizal Associations of Australian Plants”

 Fungi are referred to as the Fifth Kingdom and are more closely related to animals than plants even though many of them grow in soil. They have thread-like cells called “hyphae” which are composed not of cellulose but of chitin. It is estimated that worldwide there are more than 1 million species, about 100,000 of which have been described – many habitats have not been explored, and paid mycologists are rare.

The economic importance of fungi includes their value as high protein food, medicinal use, and as bio-controls. The downside is that they can cause disease, are poisonous in some cases, and can negatively affect our food. They are decomposers and recyclers. Fungal spores are invisible to the naked eye and can be found on every surface in our world.

The word mycorrhiza is derived from Greek words meaning “fungus root”. Symbiotic association between fungi and plants is present in about 80% of plants – fungal mycorrhiza live in or on plant roots, bringing with them nutrients such as water, phosphate, zinc and copper in return for sugar – some plants are highly depen-dent. Most mycorrhizal fungi don’t produce fruiting bodies, so are currently identified by the sequencing of their DNA and comparison to a large data base.

The four types of mycorrhizal association are:

·         Arbuscular mycorrhizas (AM) where mycorrhiza are found on the outside and inside of the plant roots. They are found in association with native plants such as ferns and allies, cycads, Araucaria spp., and Angiosperm families such as Asteraceae, Fabaceae, Mimosaceae, Rutaceae, Solanaceae and Poaceae. Fossilised remains dating back to 400 million years ago have been found – plants and fungi evolved side by side.

·         Ectomycorrhizal (ECM) association – the mycorrhiza form a sheath around plant cells rather than invading them. Examples include all Eucalypts, and species of Casuarina. Eucalypts are not fussy about their fungal partners, and may associate with fungi such as Amanita, Boletellus, Cortinarius, Russula, Pisolithus and others. Fruiting bodies of these fungi may be sometimes seen under trees or projecting from the trunks or roots.

·         Ericoid mycorrhizas (EM) form a loose mantle on plant roots, with coils inside the cells. Examples are plant families Ericaceae and Epacridaceae, heaths and heathers.

·         Orchid mycorrhizas (OM) form coils inside the plant cells. Orchidaceae is the largest plant family, and members are very specific and fussy about their fungal associations - the presence of a suitable fungus controls the distribution of the plant. In addition, the seeds of some orchids such as Dipodium spp. (hyacinth orchids) require certain fungi to germinate. Some orchids even have a three-way association with a Eucalypt and an ectomycorrhizal fungus, making the orchid parasitic on the Eucalypt! Orchids such as Gastrodia sesamoides and the Bootlace Orchid Erythrorchis cassythoides cannot produce their own food, but are dependent on wood-rotting fungi, Campanella spp. and Gymnopus spp. respectively. These are often seen on dead Eucalyptus trees.

Some plants don’t require the services of fungi to live and grow. These include Brassicas, saltbush, sundews, Banksias and Grevilleas. Appropriate mycorrhizal fungi added to agricultural crops can improve nutrient uptake, drought tolerance, and pathogen defence. They play important roles in both natural and agricultural/ horticultural systems. Our thanks to Associate Professor Dearnaley for his informative and interesting presentation, which included many more examples than have been listed here.
