Comment on Todd River: Trees in, buffel out by Alex Nelson.

Fred the Philistine’s comment repeats an age-old misconception of the state of the Todd River bed.
In general it isn’t blocked by saplings and sand. The main impediments to the free-flow of the water are causeways, these act to impede the current and cause sediment to deposit on the upstream sides.
Conversely scouring of the river bed occurs on the downstream side which sometimes exposes the water table; and in these conditions permit a larger number of young trees to germinate and grow than might normally be the case. No such problem pertains to bridges.
Many people, including long-term locals, are under the impression the Todd riverbed in town (mainly adjacent to the CBD) is unnaturally high.
The old river gums clearly tell a different story, as many of them have exposed roots which indicates the river bed has actually gotten lower.
Also, there are old river gums adjacent to the Todd River which clearly show that inundation of the surrounding land is a natural feature of the central town area.
The best example of this is the old Parsons Street river gum but also those next to the Memorial Club carpark, too. In addition, there once used to be other river gums in Todd Street (as old photos clearly show) which were cut down in the late 1940s.
River gums only germinate and begin to grow naturally in conditions of inundation so it is obvious the central area of Alice Springs has been inappropriately developed across a natural floodplain.
Historically there is now significantly less widespread flooding occurring in Alice Springs in the past few decades than what was observed in the earlier period of last century, and in large part this is due to the lowering of the Todd riverbed.

Todd River: Trees in, buffel out
Keep in mind that there was a concerted effort to eliminate buffel and couch grass in the Todd River from the Taffy Pick Crossing to Heavitree Gap 15 years ago, which (if I recall correctly) was part of the Alice-in-10 program.
The project cost about $400,000 and involved Aboriginal workers. The grass was mainly slashed and sprayed with Round-Up.
There was also removal of sand and silt build-up at Heavitree Gap. This was intended to be the beginning of a program of systematic removal of exotic grasses and other weed species along the entire length of the Todd River from the Telegraph Station to Heavitree Gap.
Both my father and I commented in the media at the time this will prove to be a waste of public effort and expense.
Our predictions proved correct – there was no more funding made available for this work, other than sand excavation of the Todd River adjacent to the town centre combined with upgrading of the Wills Terrace Causeway in 2006.
There also was no follow-up to the grass control work near Heavitree Gap. Here we go again …
In reply to Laurie Butcher’s comment about Glyphosate (Round-Up and related weedicides), there’s no obvious long-term adverse impact on the environment from the use of these chemicals. However, there’s plenty of evidence (especially in Australia) that some of the target weed species are developing resistance to this chemical.
I first started using Round-Up for buffel and couch grass control in the early 1980s when our family lived at the CSIRO Field Station (now Centre for Appropriate Technology). It cost $30 per litre at the time. I achieved complete control of theses grasses in the area around our home but after we departed in 1988 there was no further management of that ground, consequently both grasses have returned to dominance exactly as they were before I controlled them.
Prior to living at CSIRO at Heath Road, our family resided at AZRI next door (then called the AIB Farm).
It was during this time that extensive work was undertaken by the Soil Conservation Unit and AIB Farm management to achieve dust control through the establishment of buffel grass.
This was mainly done for the benefit of passenger jet airliners at the Alice Springs airport which required clean air for safe operation (yes, we can blame tourism just as much as pastoralism for the systematic introduction of buffel grass in our region).
I started gardening when I was six years old (1969), and amongst the first weeds I had to contend with was buffel grass.
I recall at first I didn’t know what to do because everyone in those days thought this was a good plant – anyway, I can reasonably claim having the longest continuous experience with controlling buffel grass of any person in Central Australia.
If anyone wants to see a good example of what can be achieved with sustained control of buffel and couch grasses, both from spraying and chipping – and consistent follow-up – go take a wander through the grounds of the Olive Pink Botanic Garden.
I’m proud to be the person who was the major contributor to achieving this result, during my time of working there from 2000 to 2008.

Is it just me, or is it the case that the “Boundless Possible” embarrassment has suffered a swift death, consigned quietly to the wheelie bin of history?
Ah yes, a government elected into office that promised us all greater standards of honesty and accountability; but no, it’s just business as usual, that we’ve long endured for decades in the Northern Territory.
It really makes no difference who’s in charge.


Four dogs suspected poisoned with 1080
@ Ruth Weston (Posted September 7, 2018 at 1:08 pm): Sodium fluoroacetate is the commercially produced 1080 poison, and is closely related to potassium fluoroacetate, the poisonous chemical found in a wide variety of plant species.
Both chemicals have the same effect, disrupting the Krebs Cycle (or Citric Acid Cycle) which disrupts the ability of cells to metabolise carbohydrates, fats and proteins for energy production.
It was biochemist Ray Murray, based in Alice Springs with the Animal Industry Branch from 1954 to 1966, who first identified the naturally occurring 1080-based compound that occurs sporadically in poison Gidgee (Acacia georginae) which plagued the beef cattle industry in the east of Central Australia and across the Queensland border.


Stagnant CBD; industrial land, rental shortage; houses hold
The photo caption “The ANZ Bank has relocated from this prime Todd Street North site, opposite the Visitor Centre, to Gregory Terrace” serves – perhaps inadvertently – to emphasise the “moving of deckchairs” in the CBD, as the Visitor Centre itself was relocated to its present site a few years ago from its former Gregory Terrace location adjacent to the Civic Centre … and that particular building, the former Queen Elizabeth II Infant Welfare Clinic, that was heavily modified and opened to great fanfare in 1997 as the new Visitor Centre, remains steadfastly vacant.
Aside from the shift of the ANZ Bank (which, incidentally, opened its doors on its former Parsons Street site in August 1962, exactly 56 years ago) and the recent Wicked Kneads shop on the opposite corner now up for sale, there has also been the closure recently of two nearby hairdresser businesses, too – one of which was for sale for a long time but obviously attracted no serious interest.
Just yesterday, walking along Gregory Terrace, I was shocked to see “For lease” notices plastering the windows of La Casalinga restaurant, a long-standing business in this town and even something of an institution.
This town has weathered significant economic downturns on previous occasions – the mid 1970s, the late 1980s and early 1990s – but I’ve never seen the relocation of so many businesses (the “shifting of deckchairs”) on such a scale as has been occurring in recent years. It’s quite a phenomenon.
This situation is concurrent with the only significant new developments – the Green Well Building in Bath Street and the multi-storey Supreme Court building in Parsons Street – being occupied by government departments and instrumentalities, to the detriment of existing commercial lease stock in town. These developments, along with the re-opening of Todd Street North to traffic again, have done nothing to arrest the decline of the CBD, notwithstanding all the hype and propaganda of government and the private sector arguing in support of them.
Recent history quite clearly shows that the proposed National Indigenous Art Gallery will prove NOT to be the economic nirvana for this town. Exactly the same rationale was given for the developments of the casino almost four decades ago, the major hotel developments in the 1980s and the Alice Springs Desert Park in the 1990s – clearly none of these institutions, either on their own or altogether, have assisted in averting the current decline of our town, and there is no reason or evidence to show that the gallery will prove to be any different.
On the contrary, it will be yet another expensive long-term burden for the taxpayer to bear.


Town Council riven by conflict, lack of leadership
@ Alex Hope (Posted August 15, 2018 at 11:43 am): You may not be aware just how true is your remark “party politics have always been a part of the town council.”
Here is the slogan for one candidate in the first town council by-election (for two vacancies) for March 24, 1973: “THIS IS YOUR … ALP CANDIDATE IN SATURDAY’S COUNCIL ELECTION. VOTE 1 HADDON, D.J.”
As it turned out, Dennis Haddon came third in the poll on that occasion; however, when Alderman Paul Everingham resigned from the town council in early July 1973, instead of going to another by-election it was decided to appoint Dennis Haddon to replace him.
Anybody who knows the history of Territory politics will appreciate the irony – but wait, there’s more: When Paul Everingham stood as a candidate for the first town council election campaign in June 1971, his election advertisements were authorised by “Peter Edward John Gunner, Stuart Highway, Alice Springs”. Yes, it was current CM Michael Gunner’s grandfather.
