COVID-19 / Australia / 7th October 2020 Update
Here’s a summary.

Grass
Got me thinking about grass in horticultural terms and how come you can mow it and it keeps growing.
Maybe I should have paid more attention in the plant physiology lectures at school.
Anyway, grasses are monocots ie. their seeds contain a single (mono-) embryonic leaf known as a cotyledon. There are approximately 60,000 species of monocots.
This makes them distinct from the other class of plants, dicots whose seed has two embryonic leaves or cotyledons. There are about 175,000 known species of dicots encompassing most common garden plants, shrubs and trees, and broad-leafed flowering plants.
So how come you can mow grass and it keeps growing when other plants don’t?
A plant produces new cells in a place called the meristem. The production of new cells together with the enlargement (division) of these new cells is the source of growth in a plant.
The meristem of many monocots is in the "crown" of the plant which is right at soil level.
The meristem of dicots is at the end of each shoot.
Therefore if you "mow" the dicot, you cut off the source of growth and new growing points must emerge from buds along the stem. Dormant buds contain inactive meristems which begin growth when the buds above it are removed.
This generally calls for strategic pruning.
Therefore, you can mow the monocot grass but not a dicot, if you want the latter to keep growing, that is.

Cicadas
There are more than 200 Australian species, most of which belong to the one large family, Cicadidae.
Here they spend most of their life underground as nymphs for around 6-7 years.
When the nymph reaches full size it digs its way to the surface and generally emerges about nightfall in late spring or early summer. It then climbs onto a tree trunk or other object and sheds its skin for the last time with the fully-winged adult leaving its old empty nymphal skin behind.
The life of adult cicadas is very short, lasting only a few weeks. After mating, the adult female cicada lays its eggs which hatch into small wingless nymphs.They fall to the ground and burrow below the surface. Here they live on the sap from plant roots for a period which may last several years.
Cicadas are notorious singers. In fact they are the loudest insects in the world. The song is a mating call produced by the males only.
Many species of cicada sing during the heat of the day.
Many of their common names were initially given to them by children. As a result cicadas probably have the most colourful common names in the insect world. Some of these include: Black Prince, Double Drummer, Floury Baker, and the Green Grocer or Yellow Monday.
Australian journalist Peter FitzSimons wrote in the memoir of his childhood, “the black prince was valued at three cherrynoses, four floury bakers, five yellow mondays or a thousand green grocers.”

Bushfire Season 2020/21 Starts
Most of the losses occurred after a myriad of dry lightning strikes in mid-August ignited a massive outbreak of fires.
Fire worries were also developing on Monday across Southern California although it was unclear how strong predicted Santa Ana winds would be. Heat and extreme dryness were expected to be problematic nonetheless.
Australia is sending 55 specialised firefighters to California mainly in leadership roles for up to a month.
They include operational commanders to supervise teams on the ground, as well as heavy plant supervisors to work with crews that clear land to make fire breaks.There has also been a request for a small group of specialised aircraft managers.
The last La Niña occurred from 2010-2012 and brought widespread flooding and record rainfall. The BOM said its modelling currently suggested the latest event would be strong but would not reach the same intensity.
The BOM also said that the Indian Ocean Dipole was also in negative territory and five out of six surveyed models indicated it would remain in a negative phase during October.
Both La Niña and a negative Indian Ocean Dipole typically increase the chance of above average rainfall across much of Australia during spring.
An active La Niña would also reduce the bushfire risk this season slightly, but would not eliminate it.

100 Beach Challenge Revisited
Three years on, COVID-19 and the ‘keep a towel distance apart' rule makes spreading out along the coast more important than ever, especially over the current school holidays and eventually Christmas.

COVID-19 / Australia / 22nd September 2020 Update
The first to seal its frontier was the Marshall Islands. Samoa, Tonga, Kiribati, Palau, Micronesia, Tuvalu, Nauru, Vanuatu, Cook Islands and the Solomon Islands, followed. Six months on, when most of the world is ravaged by the corona virus, these island nations remain virus free
Eighty per cent of islanders live rurally, many with no connection to the global economy or the tourism industry.
The resumption of international tourism would present an enormous health threat but add little to their material living standards.
Many indigenous Tahitians opposed the reopening, but were overruled by their French administrators.

Fatso, the Fat-Arsed Wombat.
Although mainly nocturnal, wombats sometimes venture out to feed on cool or overcast days. They are not commonly seen, but leave ample evidence of their passage, treating fences as minor inconveniences to be gone through or under and leaving distinctive cubic poo. Hit one on the road and it can do lots of damage to a car. We see the occasional road kill around here but have never seen one in the bush. Our neighbour thinks he has some around the creek but has only seen burrows.Which in turn brings us to ‘Rampaging‘ Roy Slaven and H.G Nelson, the alter egos of John Doyle and Greig Pickhaver, well known locally for their satirical sports commentating on radio and as well as their TV programmes eg. Club Buggery. People actually turn their TV sound off and watch games while listening on the radio. Their football commentary show (both Rugby League and Australian Rules) called The Festival of the Boot was, without fail, hilarious. A newer programme is called Bludging on the Blindside is just as funny.
In 2000 the Olympics television broadcaster, Channel 7, gave Roy and HG a nightly post Games show called The Dream. They were let loose to make the trivial serious and the serious trivial.The show was a raging success and had cult following and became essential viewing for two hours from 11pm.
They too were not happy with the official mascots and introduced us to Fatso, the Fat-Arsed Wombat as a more suitable replacement.
Fatso too became a raging success and despite rumblings from the Australian Olympic Committee virtually took over the unofficial mascot role, even making it onto the dais for some medal presentations.
As a result of his popularity a small statue of Fatso was placed outside the stadium with other Olympic memorabilia.
The Sydney Olympic Park Authority has seen fit to mark the 20-year anniversary of the Games by commissioning a new statue and putting the big-bottomed marsupial back on his public shrine, where he belongs.

Dwarf Grapevines Fruit All Year
An unexpected by-product of the dwarfing gene is it allows the vine to continuously fruit, if provided the right conditions.
Initially the discovery was used as a research tool, allowing scientists to breed different varieties with special traits in a shorter amount of time but they are now considering its commercial application.
In Australia, the fresh grape season runs for six to seven months, starting in November, peaking in February and March, and closing in May.
Australia is then a significant importer of grapes from the United States from June to December.
Now, with an opportunity to supply fresh grapes all year round, both domestically and internationally, the CSIRO is looking for businesses partner.

The vines small stature and continuous fruiting made them ideal for greenhouse operations and could be trained to grow vertical or laterally, similar to tomatoes.
When microvines are grown in a greenhouse, the control conditions allow the plants to the continuous flowering and fruiting all year round.
The plants are only dwarf in vine size and their yield is comparable to field-grown table grapes.
The berries are slightly smaller than the big ones seen in the shops, but are not an abnormally small.
They offer flexibility to rotate varieties, and their rapid growth means farmers wouldn't lose time planting or switching to others varieties, with a microvines fruiting in six months as opposed to three years for field-grown grapes.
The CSIRO is even considering introducing the microvines to nurseries to be sold as household plants.
They may not have the same continuous production, but would be great in a small pot plant on the balcony or in the home garden.

Australian Bushfires / Arson / Setting the Record Straight
That story went around the world, seized on by the Murdochs’ London Sun, tweeted in America by Donald Trump Jr, rehashed by Fox News star Sean Hannity on his website, and promoted on Fox News as the real cause of the fires.
Even the right wing politicians in our government jumped on the band wagon.
Craig Kelly, a Federal Government MP said “with the majority of these fires we’ve had unprecedented numbers of people being arrested and charged with arson offences. Now arson is not caused by climate change.”
George Christensen, another government MP said “the cause of the fires is certainly man made, it’s just not man-made climate change. It’s man-made arson that, to me, almost borders on terrorism.”
The New South Wales Bushfire Inquiry’s very recent 460-page report has a table listing all the significant bushfires in the state last season.
The table lists 32 major fires and finds that debris burning started three, power lines started two, equipment and a shredded tyre started another two, one was undetermined and all the rest (including ‘our ‘ Currowan fire) were caused by lightning strikes.
And the number started by arson?
Of course not!
