Sand dunes are a unique scene on the coast of Taoyuan Hsien. In the winter, the strong wind from the northeast blows the coastal sands into the inland area and buries rice fields and windbreaks. Therefore, an urgent task for Taoyuan Hsien is to prevent the erosion of sand in the dune areas.
A number of beefwoods were planted during Japanese occupation and right after recovery of Taiwan. The draught and salt resistant beefwoods exceptionally resist wind and sands. Unfortunately, the atmosphere has changed significantly in the last 20 years due to industrial development causing such problems as acid rain.
The ocean water was seriously
contaminated by Da-yen industrial zone and Guan-yin
industrial zone. The beaches are also polluted
by garbade. Then the gusty wind blows the polluted
salt and toxic particles from ocean onto the surface
of the beefwoods. This is why the beefwoods died
one after another. In the last few years were
planted to replace the beefwoods. These replacements
have had a good performance. In addition to the
wind resistant plants, there are a number of wild
plants on the dunes. The dune plants serve as
the first line of defense on the beach. The wind
blows heavily in the winter. Walking on the beach
shore, you must close your eyes because the winds
are so strong. Once you enter into the windbreaks,
the wind stops, and the sands remain still. A
number of birds rest in the windbreak. The ecology
in the windbreak is unique as well.
