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

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.

Todd River: Trees in, buffel out
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.

Turn rock-throwing into backflips: how community can help
I smile at the circularity of Rainer Chlanda’s preferred location of a youth hub without walls at the “courthouse lawns” (DD Smith Park), adjacent to the Alice Springs Police Station (the former Greatorex Building) and across the road from the local magistrates courthouse.
I say “circularity” because the first drop-in centre for youth on the streets at night was located in the old police station on that corner where the courthouse now stands. Established in 1976, it was named “Danny’s Place” and lasted all of no more than a year when it was forced to shut down to make way for the said courthouse.
And from that time on, youth drop-in centres, real or proposed, have bounced around from one site to another all through town; including an old house in the north end of Todd Street that was demolished to make way for an office block (now called Eurilpa House), the empty Turner Arcade – the last shop there was Grandad’s icecream shop, a once popular hang out for kids of my generation, also in the north end of Todd Mall (that was my suggestion, nearly 30 years ago) which was later bulldozed to make way for expanding Alice Plaza and new carparking spaces; and even the abandoned waterslide site in the early 1990s, which instead was demolished to make way for infill real estate development (Mercorella Circuit, near the YMCA).
We have decades of recent history of kids in trouble (or causing it) being shunted from pillar to post. As a society, history shows we’re not really fair dinkum about resolving this issue.
Sadly, there is nothing new in any of this – Rainer’s father and his colleagues were reporting on these kinds of issues 40 plus years ago, and it continues unabated to the present day.


Wakefield insists on Anzac Oval, ignores majority
@ 5 Minute Local (Posted June 14, 2018 at 5:41 pm): Definitely living up to your pseudonym. Your suggestion is not a new idea – it’s been raised several times since the early 1970s.
The last occasion was when the construction of the railway north to Darwin was being finalised in the late 1990s-early 2000s when there was significant lobbying of the NT Government to re-route the railway around Alice Springs, including by the Alice Springs Town Council.
I also took up the cudgels on this issue as an individual and was publicly criticized by a local CLP member, notwithstanding the same member several years earlier had himself advocated the removal of the rail yards out of the town centre and to re-route the eventual railway to Darwin via west of the town.
These pleas were rejected by the government as being too late or too expensive (it would have added about three per cent to the overall cost, from memory). There’s no prospect of this happening now.

@ John Bell (Posted June 13, 2018 at 7:51 pm): John, the only sacred trees on the Melanka site would be (or are) two old river red gums near the southeast corner adjacent to the intersection of Stuart Terrace and Gap Road.
None of the other trees I’m aware of on that site are local native species nor predate the construction of the Melanka Hostel.
This includes the towering lemon-scented gums of which the majority are now dying or dead as a consequence of lack of care and the extended dry conditions.
Consequently the trees don’t pose any significant issues for redevelopment of most of that area, at least as far as sacred sites are concerned.


Wakefield insists on Anzac Oval, ignores majority
@ Hal Duell (Posted June 12, 2018 at 7:59 am): Hal, I’m still in the process of collating information. Gathering the history pertaining to this location is rather like measuring a piece of string but it all adds up to demonstrating the considerable heritage value of this site, the extent of which I think will surprise many people.
The nomination for heritage listing of the oval and school will definitely proceed.
The fact that this issue has blown up in the NT Government’s face demonstrates the stupidity of over-reliance on advice from vested interests (with no regard for anything except their bank accounts) and overpaid outside “experts” who have no background in local knowledge.
Once again we see the consequences of the corporate amnesia that afflicts this town and Territory, and history shows it makes no difference which party is in power.


Cemeteries could be turned into parks
There is another method of burying the dead which is also held to be environmentally friendly, it is called “promession”.
According to the Wikipedia entry on this subject, it’s a system of disposal of bodies of much more recent origin (two decades ago) than alkaline hydrolysis (19th century).
It involves cryogenic freezing of bodies in liquid nitrogen to -196°C (in effect, crystallising them) after which vibrations are applied that shatter them in minutes into fragments.
This material in turn is freeze dried and all metal or other non-natural components (eg. fillings, artifical joints) are removed.
The final stage involves “the dry powder being placed in a biodegradable casket which is interred in the top layers of soil, where aerobic bacteria decompose the remains into humus in as little as 6 to 12 months.”
Invented in Sweden, it’s a method already expressly adopted in South Korea and has expressions of interest from up to 60 other countries.
I think promession also deserves consideration as an option for burials.
