Abused at piano concert

To Chiangmai Mail;

The four hand piano concert at Kad Theater on September 6 was wonderful except...

There were so many speeches and pitches to try and raise money for a worthy cause that many people walked out at intermission. That made a two hour concert become three hours, not to mention starting 40 minutes late. The people that were there were the ones offering support by buying 300 baht tickets yet they were abused with a hostess that was suffering from “verbal diarrhea”.

I, and many other people I heard talking, will not go to benefit concerts if this is the abuse that the supporters are going to get.

Is there a tar asphalt shortage in Chiang Mai?

Dear Chiangmai Mail,

This is just information for the readers of Chiangmai Mail and the question if you would be so kind to publish it in your mailbag section, I am sure many people would appreciate it and could be warned.

Due to the heavy rainfalls this last week the crossing Nimmaheminda Road – Huey Kaew Road becomes more dangerous by the hour.

Since the company who was supposed to repair the street left, the potholes seem to have become even bigger. (Maybe they ran out of tar asphalt? Maybe there is a shortage in Thailand and Chiang Maians could start a charity event?)

But jokes aside - for any motorbike turning left at the Amari crossing during times of rain, it is impossible to see the holes. So, the cars have to watch for sliding bikes and the bikes better use the other side of the street.

Hopefully the newspaper is also read by the municipality who could and will take action before more accidents happen.

Thanks for printing my letter.
Yours sincerely,
Geoffrey S.

More on Yang trees


This letter and photos are in response to the excellent article “75 Old Rubber Trees lost...” by Metinee Chaikuna (CM Mail August 30). I was interested in the information about the history of the planting of these Don Yang trees (Dipterocarpus alatus).

Excavation close to trees severs primary roots.

There has been considerable attention lately to the fate of these trees, particularly in regard to the drainage work and root damage that is taking place along the road at the base of these trees. Articles have appeared in other publications, and I was asked to inspect them by Ricky Ward, environmentalist, who is trying to facilitate the saving of these trees through government channels.

Large structural root can be tunneled under instead of cut.

As an arborist (professional tree care specialist) I would like to make a comment for the general interest of tree lovers and custodians, regarding the last paragraph of this article: “Nowadays, the main cause of death for yang trees are local people who like to attach advertising signs to the trees or pour cement around them, or discard rubbish around the trees...”.

I don’t buy that assessment. Although any wounding, above or below ground, can open an avenue for fungal infection, I really don’t think that attaching advertising signs is a main cause of death in these huge trees. And of course the introduction of toxic substances (paints, petroleum products and other chemicals) in “rubbish” dumped within the root zone may contribute to decline, the bulk of the absorbing roots will not be found close to the base of the trees in such large specimens. A little rubbish or cement, while not a good thing, is probably not a main cause of death.

I believe the main causes of death of these trees are soil compaction and pavement throughout the root zone, root cutting and fungal root decay.

These trees have been around a long time and many will naturally succumb to environmental impact, decline in health and die. There are many factors that cannot be controlled at this point. But one preventable cause of decline, death or structural failure, is root cutting.

When tree roots are severed, not only is water and nutrient supply cut off, but the structural support is weakened or eliminated. When the large anchor roots of huge trees like this are cut, disaster is being invited.

I inspected one of these giants, on the same road, that toppled and went down through a house a few months ago. I observed extensive fungal root decay that had advanced from old root cutting wounds. Obviously the structural support of the tree had been undermined by mistakes made in the past, the same mistakes that are being made today.
