Re: Canal du Midi

He does have a chip on his shoulder, and I know that he is not the only one concerned about the trees, but he is the only one I know who is at least trying to do something.

I didn't know Veolia were taking over from VNF.

Do you have any further information on this, please?

I suppose this will mean a near doubling of prices, as happened when Lyonnaise des Eaux, a similar conglomerate, took over our water supply. If so, maybe there will be some commensurate improvement in maintenance of the canal itself, like a bit of dredging and repair of banks.

Enforcement of speed limits would be major improvement, too. A friend in one of the hire companies tells me they charge a higher price for time run at over a certain rpm, but that the difference has no effect at all on most customers. My theory is they are the same slobs who hog the roads in their "prestige" cars.

Re: Canal du Midi

Just to advise, John has changed the red on green text which some found objectionable on his site http://www.canaldumidi.net:80/

He can answer any other comments or suggestions via the email address on the site (bottom of page)

Maybe Jonzjob could answer my question about Veolia?

Re: Canal du Midi

Bit on the slow side but I have only just read this thread.

Whilst I appreciate some of the anger at cutting down these trees perhaps a bit of research on the specific disease might highlight the necessity to tree this very seriously and quickly. I believe the 'injections' are more to do with testing a possible antidote rather than any attempt to kill the tree but of course you must have an already ill tree to test on. Sadly they don't appear to be working.

The disease, Ceratocystis platani is very virulent and can be spread by many different means hence the protective methods required. The problem is people being people and possibly the lack of educating those that use the towpath on a day to day basis and of course the holiday makers who take their holidays on or by the canal just spreads the disease further. Then there is the elements of course and in particular the wind as these are spores. The only way to eradicate this is to cut and burn hoping that in doing so you can save the good ones.

English readers may find the following information of interest.

Ceratocystis fimbriata f. platani is a wilt pathogen causing pronounced xylem staining, severe wilting and tree mortality. Staining can extend longitudinally in the sapwood at a rate of 50–100 cm per year and can reach the heartwood along the medullary rays. Infected trees exhibit sparse chlorotic foliage and sometimes sunken, elongated or lens-shaped bark cankers that can become roughened and black with age. Infection commonly occurs through fresh wounds, although transfer between trees can occur across root contacts.

For unknown reasons the disease seems to have become less significant in the United States in recent years, but in south-east France and Greece there have been serious losses of shade trees, with infected trees dying within 3–7 years. This pathogen poses a significant risk as it affects a key urban amenity tree species and can be spread easily through the movement of infected cuttings. It also produces resiliant, long-lived spores which can persist in soil and unsterilised pruning tools. As the disease mainly proliferates through human activity the spread can be limited by sourcing plant material from regions free of the disease, and by disinfecting pruning tools with alcohol. Larger agricultural equipment such as terracing machinery should be jet-washed with water to remove any contaminated soil. Affected trees decline so markedly that it is unlikely that the disease could be overlooked, so it is unlikely that if it has reached the United Kingdom it would remained undetected. However, if readers are aware of any trees exhibiting such symptoms we would be grateful for further details. (Further information can be found in Walter, 1946, Griffin, 1968, Vigouroux, 1979 and Panconesi, 1981)

I seem to remember some time back a load of these trees were found to be infected, they were in Windsor park and have been destroyed, Charles was not amused but understood it needed to be done.

Re: Canal du Midi

The state will only pay a third for the works that will need to be done, leaving the rest for locals to pay:

Re: Canal du Midi

Whilst holidaying in Salleles d'Aude in august this year and cognisant of the problem on the canal du midi I noted that much of the canal de la jonction was lined with pins séculaires.

Re: Canal du Midi

I have no idea which part of the Junction is in your photo Pachapapa, but when I crewed for my friend, about 4 years back last March, in his 30 M peniche and we stopped about a kilometer past Salleles I took this photo looking back towards Salleles and they are all platan trees. I can't remember seeing anything else on the way down, but we were both cold and tired at the time so I may well be wrong? I hope I am.



It was taken just before the ecluse before it crosses the Aude and becomes the Robine. That is where the dry dock is that we put the Lodela on for her pressure wash and repaint. She's here and lovely http://www.penichelodela.com/lodela2/site/accueil/accueil.htm

There are a lot of stretches that have conifers as well on the Midi and there are oak and a lot of tulip trees in there too. The tulip flowers are beautiful and the leaves are so different in that instead of the usual 5 fingers to a leaf there are just 4!



John.

Never forget that you are unique, just like everyone else.

Re: Canal du Midi

From Sallèles towards Amphoralis there are pins parasols, Sallèles towards the Aude there are plane; although we crossed the railway bridge to the south side of the Aude to reach the start of the Robine I cant remember the trees there but I have some photos.

By the way have you been on the multiple locks at Beziers that was a memorable site.

Not just memorable...World Heritage...
