枯れたのではなく、枯らしているのだそうです。この木は外来種で成長が早く、巨木になるのですが「イゼル」の経験で分かったように、非常にもろくたおれやすいので、電線を切ったり、家屋を壊したり多くの被害をもたらすので、州政府も応援して撲滅を図っているそうです。
調べてみると、木に切り込みを入れ除草剤を塗ると、一年足らずで枯れ始め、最初枝が落ち、幹だけになり、倒れてしまうそうです。伐採しようとすると大変の費用が掛かるが、この方法だと安く済むとのことでした。隣家、特に空き地のアルビジアが危険になり、持ち主が対処しないと州が処理し、持ち主に請求することまでやっているみたいです。
This time,Sep.1/2015, I see many Albizia forests are dying. Those forests are very beautiful so I feel very sad. Last year I saw many Albizia fell down by the strong wind of Hurricane Iselle. And I thought so many trees got damage at the root by that storm so they did not fall down but died. Just to make sure, I asked my friend, Alan, about this. It amazed me....
Those did not die but were killed. Albizia is an alien and grow very rapid and becomes very big but it is very weak. As we experienced at Isele, many Albizias fell down and gave big damage about electric wire, houses,road, etc. So we are killing them and the County assist it.
According my research, make shallow cuts in the wood and put a weed-killer on it, it begin to die in a year and all blanches fall then die.
景観の上からは、非常に美しい木で、この二枚の写真を比べても、下の写真のほうが美しいと感じる人は多いと思います。もちろん、時々来る観光気分の私が、住んでる人の被害を無視してそんなことを言ってはいけないと重重承知ですが,ちょっと考えさせる問題でもあります。
These photos are the place of Boiling Pod, a little up the Rainbow Fall. Lower is 5years ago, upper is now. Dead trees are Albizia, you can easily understand the speed of growth of These trees.
But Albizia is beautiful tree, I guess many people think lower is more beautiful than upper.
Think about the suffering of the resident, of course, I never say so but it is very difficult problem.
