家园 没有坐车,不过也看到不少

去年夏天,去新奥尔良的路上,迷路了。

有人说,曲轴是不是脑子不清楚,如此发达的公路系统,我也能迷路。其实,我也没有故意迷路,只是中间休息的时候,有个特别热心的当地人,说不要走高速,从他那里到新奥尔良,有一条特别漂亮的沿着河的路,风景极佳。

我们就傻乎乎的上路了。河的风景没有见到一点,但是看到了非常多的南方种植园时期的建筑。也就是大片的草地和几排高大的树木,里面一幢房子,宽大,有的在草地的边缘,还有小小的房子,有人说是原来奴隶们住的地方。跟北方的建筑相比,一看就是地主富人啊。不知道现在里面住的是什么人。

家园 还没去过就都没了,遗憾啊~

这些老橡树不知道有没有危险。。。

家园 橡树是怕水淹滴

橡树是怕水淹滴,因为它的根部不能老被水泡着,没法呼吸。

我们这里的橡树今年大量死亡,因为降水过多,还有温度过高。

Oak Tree Deaths Tied to 2003 Hurricanes

Arborists say that the demise of hundreds of oak trees in central and eastern Virginia -- many of them older than 100 -- is due to drought conditions the trees suffered for several years before a drenching from hurricanes in 2003. This summer\'s high temperatures have further stressed the trees, causing them to die.

\"If you track the path of Isabel, that\'s exactly where these trees are dying,\" said Dean Smith, a forestry technician at the Goochland County office of the Virginia Department of Forestry.

When hurricanes Isabel and Gaston created floods, it was difficult for the trees to breathe because they didn\'t have smaller roots to find air pockets in the soil. Then, roots began dying, opening the door for destructive fungi and other organisms, and killing the tissue that carries water to the rest of the tree.

Finally, last month\'s 100-degree weather hit the oaks when they needed water, killing them off quickly.

The forestry department has received dozens of calls about \"hundreds of dead or dying oak trees\" in eastern Virginia.
