We experience numerous typhoons each year in Taiwan. Under some intense winds, buildings and constructions are often destroyed during the storm. But do you ever wonder how some of our trees can survive through the

blow? Here on CTS, we uncover that mystery.

There were 6 typhoons that hit Taiwan hard back in 1994 with 4 of them super typhoons.

In 1996, the strongest typhoon in the last half-century, namely, Herbert, hit Taiwan.

A research team from National Normal University has been in the mountain region of Fu Shan area of I-Lan for research.

The team found out that, only about 2% of the trees would die after typhoons hit, but the storm of the same intensity in central or North America would kill off a quarter of the trees in the forest.

The scholars discovered that trees in areas such as Taiwan, where an average of two typhoons would hit per year, have developed a self-defending mechanism.

In addition, the result shows that, the nutrients in the soil would take about 500 days to recover in central or north Americas but only a short 5 day period is needed for Taiwan soil to recover,

which showed the power of nature and its recovery amazing mechanism.

However, water and soil conservation of man-made forest cannot be compared with that of a natural forest.

With the recent drastic change of global weather pattern, scholars are not optimistic on the issue of whether or not plants in Taiwan can evolve fast enough to adapt to stronger typhoons in the future.
