In support of common names – we are losing our vernacular

December 1, 2022 by mccgadmin

 We are losing some of our most colourful and descriptive language.  What is worse we are replacing names of our plants, birds, mammals and fish with names we cannot pronounce, spell inaccurately and have no idea what they mean as very few of us have the necessary background in Greek or Latin. What’s more we are using these scientific names inaccurately in our general usage.

Dendrobium bigibbum is our Queensland floral emblem.  I couldn’t find out what or who was bigibbum. What’s more nearly any Cooktown orchid you happen to buy from our nurseries won’t be a scientifically accurate specimen of Dendrobium bigibbum as it is likely to be at least a selected horticultural Cooktown Orchid cultivar or even a hybrid – neither deserving a scientific label.

What about our faunal emblem the Koala. There may be a few who know it as Phascolarctos cinereus, but Koala’s much easier.

The birders have made an effort to simplify our bird names and have a standardised list of common names of all our Australian and most of the world’s birds. There are claims Scientific names are unique, while there are many common bush-names for the same species. However, there is also some credibility in the view that scientists are changing their names of our flora and fauna to an even greater degree now they are using DNA to sort out the vague divisions of some of our species. For instance a Google search showed our Queensland bird emblem, the Brolga’s scientific name was Antigona rubicundra, Antigone rubicundra and Grus rubicundra in three different current articles. In the past it has also been Ardea rubicundra, Grus antarctica, Matahewsia rubicundra and Grus australasianus. Hardly a history of consistency comparable to the stable common bush-name of Brolga.

Language evolved about 50,000 years ago allowing us to communicate better to assist humans to hunt, farm and defend themselves in a harsh environment. Many languages developed. Some independently and some as local dialects of established languages. Unfortunately many very workable languages have died out and it is reckoned 90% of our languages have gone. We are going the same way with the use of scientific names taking over local common names especially in the horticultural field.

A “Greenie” – Scaly-breasted Lorikeet

We are replacing very descriptive names in a language we all understand with Greek or Latin derived names very few of us can comprehend. The binomial nomenclature system is great for scientists as in theory it means every species has a unique name that should be understood by other scientists no matter what language they speak. However, these are for scientists and it is much clearer for most of us to communicate with names we can pronounce and understand and are descriptive in our own language.

A few years ago you could go to a local nursery and ask for a Red Bottlebrush. A few of us knew it was a Callistemon viminalis and it was generally grown from seed and it was representative of C. viminalis. Now go to a nursery and it should be listed as Melaleuca viminalis as the scientists have changed its name again. But now you will find all sorts of M. viminalis with different colours, shapes and heights as they have been cloned by Horticulturists who have bred or selected different forms that really should be labelled M. viminalis c.v. (cultivated variety), or Melaleuca viminalis (hort) or Melaleuca X (hybrid).

Isn’t it much clearer if you just ask for a Pink or Red Bottlebrush. Much more descriptive.

Red Bottlebrush “Captain Cook”

The Moggill Creek Catchment area was settled by farmers growing fruit and dairy farming that had far more contact with nature than most of our residents do today. They had names for our trees, birds, mammals, fish and reptiles that were well understood and very descriptive. These are highly likely to be lost in another generation.

Our  Trichoglossus haematodus (or is it  Trichoglossus moluccanus) is a Rainbow Lorikeet. To a Brookfield local a few years ago it was a “Bluey” to distinguish it from a “Greenie”,  a Scaly-breasted Lorikeet. A Corymba maculata was a “Spotty”, a Spotted Gum and a Tropidonophis mairii was a Keelback snake.

Sure, they may be called by some other name in another area, but we have our own names (language) in our own area. The names were far more understandable and descriptive than the scientists’ Greek and Latin names. The Priests in olden times used Latin so the masses were ignorant and relied on them to interpret the Gospels. Are the scientists still using foreign tongues we can’t easily translate to keep us ignorant of the wonderful world of nature and causing us to lose our local vernacular?

Moggill Magic – Old Gold Creek Sawmill Forest Walk

November 13, 2022 by mccgadmin

The Grand Opening Event is to be rescheduled again. Unfortunately parliament will be sitting on Dec 3rd so our officiating guest is now unavailable.

The new date is expected to be March 4th 2023 but will be confirmed closer to the date.

 

Please join us for the offical grand opening of the walk.

Officiated by Elizabeth Watson-Brown MP Greens Member for Ryan

When:

Saturday 4th March 2023
10 am – 12 pm
Where:
The Cottage, Gold Creek Reservoir Carpark, End of Gold Creek Road, Brookfield, QLD 4069

Book your free ticket through Eventbrite 

 

A new attraction in the Moggill Creek Catchment has been the result of the foresight and hard work of Gordon Grigg who lives next door to where the Gold Creek Sawmill operated from 1919 to 1923.

Gordon began the project about two years ago and it is already a very pleasant walk that will appeal to native plant enthusiasts and bird watchers. The area is remnant Dry Rainforest and Vine Scrub and retains many of the species common to this fast-diminishing landform that used to be prevalent in the Moggill Creek Catchment.

The Walk is an easy stroll and is located just before the entrance to the Gold Creek Reservoir at the top of Gold Creek Road and access is from the parking area.

Gordon was aware of the area which has an amazing range of trees, some of considerable size, and so far, 100 species have been identified and 200 of both saplings and mature specimens labelled. Previously the area was difficult to access with heavy Lantana undergrowth until Gordon and Andrew Ness developed a sinuous track through it and employed some contract weeders to ‘break the back’ of the clearing job.  Subsequently Robert James and Keith Rickart have become regular contributors to maintaining the track and clearing the worst of the weeds. The mulched pathways have been located around the few remaining remnants of the sawmill and through the forest, some of which was planted by Gordon’s Upper Gold Creek Bushcare Group (Section 9) about 20 years ago. There are a lot of mature trees, which were there before the sawmill was operating in the early 1920s and there is a lot of regrowth, including some surprising finds including a beautiful unidentified fern that cropped up in the middle of one of the paths after the recent rains.

Unidentified fern growing after recent rains at the Sawmill Walk

While there is little recorded about the sawmill, it employed about 12 men and contributed to quite a sizable community and a school was established at the end of Gold Creek Road during this time.  By 1923 the immediate area had been logged out of suitable trees and the sawmill was moved on to another area. Now the main evidence is the large concrete platform for the steam engine that operated the mill and some smaller relics scattered around the site, including a huge flywheel thought to be a governor for the sawmill engine.

Gordon was able to secure a grant of $10,000 which was used for Lantana clearing and labelling of specimen trees.  Gordon has worked closely with Andrew Wilson, who has identified the tree species and helped with the labelling.  High quality aluminium labels have been used for many of the trees and further temporary labelling has been used which will be replaced with permanent labels when funds are available.

Birders can expect to see some interesting birds in an early morning visit to the Sawmill Walk. Rarities such as the Black-breasted Button Quail and the White-eared Monarch have been found in the area and Spotted Quail-thrush and Wompoo Fruit-doves are relatively common. Swamp Wallabies, Pademelons and Mountain Brushtail Possums are known to frequent the area. It provides such excellent habitat, that as more people visit the Sawmill Forest Walk more interesting animal and plant species are sure to be found.

The Gold Creek reservoir is a well-known birder and bush walker location and as the Sawmill Forest Walk becomes better known it will be a valuable extra attraction for visitors thanks to Gordon and his helpers.

Wildlife Matters – Two Jezebels

November 6, 2022 by mccgadmin

At first glance these butterflies could be mistaken for each other. Both occur locally.  They are similar in size and have the same colours on both upper and underside, yet there are subtle differences between these two adult butterflies. Firstly, they belong to different families. The Black Jezebel (Delias nigrina; on right) is a member of the Pieridae, whereas the Jezebel Nymph (Mynes geoffroyi; on left) belongs to the Nymphalidae.Their wing patterns differ. Additionally, compare the hindwings and you’ll discover that the outer edge of the Black Jezebel’s is rounded whereas on the Jezebel Nymph’s hindwings irregular extensions or projections appear, quite different to the ‘tails’ of Swallowtails.

Both butterflies lay their tiny eggs in clusters. Once emerged, the larvae remain social when feeding. At the time of pupation, the Jezebel Nymphs stay together in groups, and you can see substantial numbers of chrysalises hanging from branches. In contrast, the Black Jezebels seek out solitude.

While adult butterflies are opportunistic when seeking nectar, their larvae are dependent on specific food plants. Locally Jezebel Nymphs rely on the availability of Native Mulberry (Pipturus argenteus), found in or at the edge of dry rainforest and currently doing well in riparian areas. The Black Jezebel larvae choose and depend on mistletoes for their wellbeing, all parasitizing eucalypts, wattles, paperbarks, she-oaks and other trees. Both butterfly species are common in Brisbane and on the wing throughout the year.

Can you identify these butterflies of Moggill Creek using the MCCG Digital Field Guides?

Which of them is the odd one out?

1.

2.

3.

ANSWERS:

  1. Caper Gull (Cepora perimale)

  2. Caper White (Belenois java -female)

  3. Caper White (Belenois java -male)

    The Caper Gull (Cepora perimale) is the odd one out, the other two are both Caper Whites – female and male of the same species. However, the strong yellow colour in the photo of the female Caper White fades quickly after hatching.

Wildlife Matters

October 9, 2022 by mccgadmin

Wonderful Waterways

There’s more than meets the eye in our creeks. In the Moggill Creek Catchment, there are at least 20 species of native fish and countless more macroinvertebrate species, a.k.a. water bugs. A specialist group called the Creek Health Monitoring Project (CHMP), part of the Moggill Creek Catchment Group, have been monitoring local waterways since 2011. Results from water quality testing, macro-invertebrate and fish surveys indicate a remarkably resilient ecosystem. This can be highlighted by consistent findings of sensitive water bugs like caddis fly nymph which sensationally hollow out sticks to create an impressively camouflaged home. Sensitive water bugs like the caddis fly would not be able to exist in polluted waterways so their presence is an indicator of good waterway health.

During a CHMP event, trained team leaders oversee native fish surveys, where it is common to gaze the magnificent colour of Crimson Spotted Rainbow or Pacific Blue Eye up close. Surveys from the previous two years have recorded 602 fish with 317 of these being native species and 285 being exotic species.

Despite the relative health of our local creeks, there are many risks and things we can avoid to help native fish and water bugs thrive. Car washing should be done in such a way that the water, which could contain harmful chemicals from the washing liquid and oil, doesn’t run off to the drain and into the creek. Another thing to resist is releasing any fish into waterways. Any fish released, native or not, could be carrying harmful diseases that will disrupt and threaten the balance of the creek.

The CHMP team will hold surveys again in November 2022. Follow MCCG on Facebook or email [email protected]  subject ‘add to mail list’ to stay up to date or get involved in waterway health monitoring.
