People Impacted (Good, Bad, Ugly?)


The human impacted the ecosystem is bad. Because of the development, people build a lot near the coast which make the mangrove forest disappear. Bruguiera conjugate and Ceriop tagal have disappeared due to the expansion of the Port of Kaohsiung in Taiwan.


Human Impact

In the past few decades, Taiwan use land reclamation in order to maintain its economy and use it for the construction of the industrial area, embankments, roads, harbors and fish ponds. The direct results of using this kind of land make the high tide line zone disappear. Take Changhua County Shengang bottomland Shihgu for example, the bottom-land were planning to build a landfill in 1999, although the plan stopped but it already fills out a large area.

The second interference, it happened in all parts of Taiwan, such as dumping the waste of building, oyster shells, garbage, and the river pollutants discharged into the sea, and so on, and continued on the harm of the mangroves forest.

Last, though not to the pollution or land reclamation, on the contrary, it is based on the Coastal Protection. This third threat is about since 1956 or earlier, all levels of government and private conservation groups in succession actively mangroves planted way construction is the coastal windbreak. The high tide line of the sandy zone in many sediments, the original is not suitable for the growth of mangroves, they are nothing but a dense mangrove distribution; for example, the artificial mangrove planting around Hsinchu City coastal wildlife sanctuaries high tide line zone. Because of the inter-tidal zone was invaded and occupied the biodiversity in the ecosystem decreased.
