We can help stop Didymo

[access4WD]

Probably we should now carry in our vehicles,
A 5 litre Pressure Spray unit with a mixture of Water and 5% detergent premixed. That way at the completion of river trips on the river bank before leaving we can Check, Clean & Dry.

Also note in any one day a river trip should only be in one river system, so say doing a trip in the Waipara, then do not stop of and drop into another river on the way home.

The following will be of interest of 4WD people It was been circulated before I think, however a reminder to us all is not a bad thing:-

Information for 4WD Vehicle users:- (please visit http://www.biosecurity.govt.nz/didymo )

Before leaving a waterway,
Check: check items for clumps of algae. Leave any debris that is found at the waterway.
Clean: Clean all items for at least one minute with one of the following:
• Hot (60°C) water
• 2% solution of bleach
o A 2% solution is 200ml of product with water added to make ten litre
• 5% solution of salt
• 5% solution of dishwashing liquid
• 5% solution of antiseptic handcleaner
• 5% solution of nappy cleaner
o A 5% solution is 500ml or 2 cups, with water added to make ten litres.

All these items can be found at your local supermarket. We recommend that you use products that are biodegradable.

Dry: If cleaning is not practical, dry the item to the touch and then leave drying for an additional 48 hours.
Specific cleaning methods have been developed for some freshwater activities.

Vehicles should be cleaned thoroughly, including spraying the underside of the vehicle, tyres and any other parts of the vehicle that have had contact with water with a decontamination solution. Use a solution of 5% detergent. Commercial carwashes with an underside spray would be suitable.

The decontamination solution should be left on for at least one minute and may then be rinsed off with water that has come from a town water supply.

Tyres Tyres which have backed into streams or been used for stream crossings must be carefully checked for clumps within the treads and then scrubbed, soaked or sprayed and flushed with a decontamination solution of 5% dishwashing detergent, ensuring that there is a contact time of at least one minute. They may then be rinsed using water that has come from a town water supply.

[Mark]

Well it looks as though it's time for us North Islanders to start taking a bit of extra care when traversing multiple waterways as well.

Didymo found in North Island
Biosecurity agencies are on full alert after signs of the noxious algae didymo were found in four of the central North Island's most pristine rivers.

i blame it on the fishing people and kayakers which makes me feel better . at my last job at OPC i installed 2 salt water tanks that every thing that went into the water went into like kayaks shoes life jackets canoes etc .every group would do it when they got back , and if they were crossing more than 1 river each day they would carry a bleach solution with them ,and they have been doing that for probaly 2 years or more, it is a pity more people didnt take as seriously as it sounds like we have river snot here now and in the rivers that surround my house whakapapa and wanganui rivers.

Good to have another reminder, I am sure we are all doing our best and Just like the Verroa Bee mite (was in the north island and DOC and the Govt did not attempt control) when it did arrive in the South Island, it was identified and the SI Bee keepers have been able to control it and even DOC admit the affected area in the south island (infected hives) is reduceing.

We can slow its spread between river systems but there need's to be research into controlling it in a existing river system the Univercity of Canterbury had great success but the labour hors in managing it was too high for the Government.

Not sure why they do not have people on the Dole and Injury benefits work for the enviroment Easy work just time.

The spread is inevitable and it was going to happen sooner or later.

Whilst I am in full support of being vigilant we cannot stop birds and completely decontaminating a boat, rod or vehicle is pretty hard.

To see Rock snot floating down what was a lovely river is not nice and tends to isolate the places where we want to go for a BBQ or picnic. A real shame that nothing is being done about it.

If infected with didymo, rivers could made be off-limits to the public or, in certain circumstances, have a copper solution washed through them to kill the algae.

They talk about this, but have they actually tried it on a river?

It is my understanding that they are/have conducted limited trials deep down south. Some natural solution that doesn't effect the other plant/ animal/ fish life. Somebody down that way might be able to fill in the blanks.....

perhaps raise the issue at the next ORE beer nights.....

Jerry that sounds like a Tui add, "YEAH RIGHT!!"

ORE Beer nights are about drinking beer, eating burnt sausages, slagging each other off and having a good time. A bit like NON Assn trips really but with less driving.

Perhaps you should organise a special meeting at Marks place to discuss the Didimo issue (who came up with that name, sounds like a Pokemon). You can bring a slide show and everything.

The spread is inevitable and it was going to happen sooner or later.

Just like gorse, deer, rabitts, stoats, nissans and the rest of it once it gets here it just spreads till its everywhere

[NJV6]

Yep afraid so.

From what I understand there is no eratication and control being what the 1st post here said, ckeck, clean, dry.

Best results I have seen is a flood. not enough to eradicate or anything that lucky - just cleans up a good part for a while. Worst looking thing is when the river drops in the summer and you get white mats covering what is normally river.
