Buugger that. I would rather see my house blown away than have to deal with the mmess golden canes leave(mind you I hate gardening anyway so I mmay be biased with that comment). They also are a favourite home for rats which I find is another reason to avoid them. As flylady said though they do provide very good protection and even if they fall they are not that heavy.

We had a clump of the larger yellow bamboo with the green stripe (don't know what the name of it is )growing at the back of our house and the entire clump of Bamboo got blown straight out of the ground root ball and all during the first part Yasi.

I thought Bamboo was a plant adapted to tropical weather and high winds ... but i guess i may have been wrong.
How big was the Bamboo clump?

The clump was a good 2 1/2 years old and the root ball was about 1.2mtrs x m.2mtrs and about 30 cmtrs deep.
some of the other larger bamboo that we have didn't get blown out of the ground but they ended ep twisted mangled and even snapped, and bamboo has quite good tensile strength.

is see the statistical prediction website http://www.meteo.nc/espro/previcycl/cyclA.php?type=gen#1
is predicting/ probability of "something" in weeks 2 and 3 (only a 10% chance..)

From further reading of a library book about Permaculture they have expanded the placement of the bamboo to have like a layered defence. i.e. large trees about 3x times the distance from the house as the maximum height; so a 10 metre high tree would be planted a minimum of 30 mtres away from the house. As you got closer to the house clumps of bamboo offset to each other so that they form a semi soldid barrier. Smaller varieties to leeward moving back into a denser larger variety at the back.

Golden Canes are just another palm not a bamboo. They are filled with water, very heavy but are not chainsaw proof. I cut what was left of ours down after the Yasi and poisoned the roots. What a bloody mess they made - never again. Oh and don't be tempted to plant Mahogany Trees ethier. They did a sterling job of snapping off about 5 metres above the ground and destroying my carport roof.

Bamboo is useless as a wind defence because it typically does exactly as you described and the whole root ball tears from the ground due to its very shallow root system and upper weight.

I've seen footage of entire forests of it destroyed in Typhoons in Asia.

I agree with you SBT about the African Mahogony, we had 5 very large ones in our backyard and all snapped of in Yasi about 1 metre above ground.
What a mess to clean up,luckily we are on an acre and they were planted well away from the house. Being original Mexicans (south of the border) we got advice when we got up here and was told they were a great shade tree and grew quick, they did, but we were not told of their instability in a Cyclone.
Needless to say they will not be replaced with anything. 5 less to clean up next time.
Only downside is they did protect our house a bit from the wind and we don't have that buffer now.

Since my last text I have checked my email and have received a reply from Harden Up.
They have now added Cyclone Tessi to our area.
Also a long letter of explanation about the name and an apology to anyone who felt it was a slap in the face. (their words not mine)
Going by what they said its about trying to make people become more responsible for themselves in times of disasters and less dependent on others eg: emergency services.
To get people to think about what they need to do in these times (emergency kit,evacuation plan) and be prepared to help yourself as its not always possible for others to help you.
They also acknowledge that most people in the North prepare for these events on a yearly basis and this is what they are trying to achieve state wide.

continued model runs of something forming over fiji or west of fiji 7 days out though. is this from the current low retrograding back towards fiji? Or, something forming from the moisture off the solomons?

The knowledge gained on this Forum is invaluable. Very helpful to know the formula for safe distances when planting trees around the house.
Before we get too busy with cyclone watching, I have another question...
I have learnt on this forum that storm surge is one of the most dangerous components of a cyclone. Any ideas on how many metres from the high tide mark should be safe to build a house (from the storm surge of a Cat 5). The land is 3-4 metres above sea level, facing NW?

Probably start a new thread here and if the mods don't like it they can move it. I find teh whole Australia AOR pretty restrictive which was one of the reasons i asked for this forum to be created. So Yeah just start a new thread.

Hi Guys,

There were some earlier posts on plants and cyclones and I thought I should give you some pointers.

The first step towards having cyclone resistant trees is in your soil. Make sure you dig a really big hole for your trees, especially in new subdivisions where a small amount of topsoil has been placed onto the local soils. If you have used a post hole digger make sure you rough up the sides of the hole to stop roots from chasing each other around the hole. Trees will benefit from less frequent and deeper waterings, which will force them to put their roots down deeply seeking water.

African mahoganies don't stand up to winds due to their pathetically small root ball in comparison to their tops. About five tree species caused most of the damage around Townsville in Cyclone Yasi. There was a report written about this - google Yasi,tree, Ergon and Calvert to find the report.

To find out the best wind resistant trees in your area look for trees growing in areas that are subjected to rough weather - look in the flood plains along creeks, the ridges along the top of mountains and exposed areas along beaches. In Townsville you can see the Melaleuca leucandendra at the base of Ross River Dam that get bashed around by flood waters every year and are still standing strong. Anything that is still growing along exposed areas of the Strand or Pallarenda should be tough.

When a cyclone is nearing and you decide to do some pruning open up the plant to allow the wind to pass through it, and keep your pruning symmetrical. Also don't water your garden in the days leading up to the cyclone as a waterlogged soil does not have any strength.

Windbreaks are explained in the factsheet below:
www.pir.sa.gov.au/__data/assets/pdf_file/0004/39127/Windbreaks_for_the_Upper_South_East.pdf - 2010-04-07

JCU also has a listing of tress and winds:http://www-public.jcu.edu.au/discovernature/choosingplants/index.htm

The new TSR forceast(Nov 2011)for cyclone activity in the Australian region:
TSR Nov forecast

The thick of it....

20% above average cyclone activity increased from 10% in the October forecast.

Forecast probabilites(see link for climatology probs, aka averages):

Activity-

70% above average.
25% near normal
5% below normal

Land fall-

45% above avergage
36% near normal
19% below normal

sounds not too bad...or not too good depending on what side of the coin you are?

On a loco note... er, I mean local note, so boring..... if the ridging dosen't stop I will go insane....but it is more than welcome back once cyclone season starts.... by me anyway! smile

163E - 13S is looking like deveopment too. upper level low feeding colder NW winds into the area above the surface trough. Must be quite a dry upper as the instability is rapidly intensifying.

175E and 165E looks quite good, is the upper low your talking about poncho at 155E, or is that something else
