Maintain balance between people and the ecosystem


Do not development the area that is not been development and try to save the one that is dying. We people do not really need that much stop asking the environment for more.


Mangroves forests are located in coastal and river estuary regions. Causes of the rapid development of the economy, coastal environment have suffered huge pressures and damages which have made some species disappear. Luckily, there has been an increasing awareness of mangroves conservation and management in recent years, especially in term of waterfowl habitat protection and mangrove conservation. Selected coastal areas are slowly but surely becoming designated National Conservation Areas in various cities and counties.

Future


Even some of the mangrove area has been protected; if people keep ignore the rest of the mangrove sooner or later mangrove forest will be gone in Taiwan. Once the mangrove forest is gone, nothing will prevent coastal areas from erosion and typhoon.


Future prospects:

Selected coastal areas are slowly but surely becoming designated National Conservation Areas in various cities and counties.

Since there has been increasing pressure to conserve and restore mangroves due to the international attention placed on environmental conservation, sustainable resource use and biodiversity conservation. First, maintain the ecology’s current condition. Stopping the human impact is the most common method for environmental conservation. Second, recover its ability to produce in the future. Not just focus on restore the area’s original ecosystem, but to preserve and increase more living species, and for the future of sustainable development. Last, besides focusing on conservation areas and sustainable conservation, the nurturing of mangroves can also prevent the nature hazard in the future.

Status of the protected area


The status of that protected area is pretty good. It has combine protected area with education purpose. People can go there have fun and learn more about the mangrove forest.



What can be done to improve human impact?



(1) All planning authorities should protect the provincially important wetlands. Its policy purpose is to use the land for the planning process to define and protect wetlands; goals are to achieving zero loss of wetlands. Identified important wetlands in the area and do not allow any development of behavior.

(2) Once identified the area, all planning authorities should under the Planning Act, the protection of its inclusion in the official plan, zoning control regulations and other development decisions.

(3) All planning authorities should be encouraged; in order to protect non-provincial government recognized the important wetlands. This policy is to make up for the provincial important wetlands which think it is not important. Local government may attach great importance to the non-important one, and as much as possible to preserve the wetlands.

(4) Land which is adjacent to the protected wetlands, need license to develop.  But it is limited to not detract from the original wetland functions and affect adjacent land features; required environmental impact assessment.

Let the environment has time to rest.

Protected Areas


There are thirty larger number of mangrove distribution areas, where there are legally designated as mangrove protected areas such as Jhuwei mangrove protected area, Hao-Meiliao mangrove conservation area, the Chunan Jhonggang river mangrove protected areas, the Hsinchu orang Kong mangrove protected areas, Guandu Nature Reserve District, Waziwei Nature Reserve, and the Sihcao mangroves reserved area. The other mangrove forests are facing the destruction of land development and environmental pollution.

Benefits


The roots of the mangrove not only intercept sediment expand on beaches, but also protect the bay from the giant wind or big waves directly attacked which have excellent security revetment function.


1. Filter the organic matter and pollutants from the terrestrial runoff which come from inland.

Mangrove species through their roots absorb inorganic substances in water, reduce water pollution, example: the microbial metabolism soil surface absorption, chemical precipitation and absorption by plants and other. This method can reduce the suspended solids, chemical oxygen demand (COD), nitrogen and phosphorus, and other elements, and metal.
The Tamsui River mangroves cumulative metal, the cumulative site to the roots of the highest, which mangroves should have fixed the heavy metals in the sediment, in order to reduce its role in the food chain cycle cumulative.


2. throughout the formation of soil sediments, to resist the impact of the tides and floods.

3. Provide habitat for many birds and marine animals and foraging environment.

4. It can be used as timber, firewood, food, herbs, and other chemical raw materials.


5. Mangrove has the value of people from a variety of angles like appreciate, entertainment, knowledge and education to achieve the purpose of tourism.

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.
