Jeopardy Chapter 18

A great resource to study with is this website. I just stumbled upon it and it has great quizes and outlines... []

I have abided by the HFA honor code in completing this assignment. –Zach Anderson Zach Anderson Allen 6th APES 1/19/12 Ecological Restoration Project In 2004 a tsunami hit Indonesia. It was especially bad in Banda Aceh, Indonesia. The part of the ecosystem I am going to focus on is the mangroves and costal ecosystems. During the massive waves that hit Aceh the mangroves were especially detroyed. The plants there were there were torn out of the ground and the ground was made unsuitable for future mangrove growth. That is with out severe restoration.The initial reaction to this event was too help the survivors get food and water and housing back. However after a couple years the major concern became the costal ecosystem. Many of the areas that were restored have failed as can be seen from the low percentage of plants that actually survived after being planted. A couple reasons can be identified because of this. The first is the lack of research about plants that would survive in the mangroves. The plants were not looked after either. Once they were planted they did not get continuing care. The community was also not very involved during the restoration project. The majority of the community were simply used as workers and not educated as to what needed to happen to continue the process.

There are many struggles with the restoration of many costal ecosystems in Aceh. The first is that most of the workers there see restoration as a second or even third priority. They do not put there full effort into what is going on. The next biggest struggles is that the volunteers that tried to help were just that...volunteers. They were not properly trained to select quality seeds and grow the seedlings in a nushery before they were planted in adequate planting sites. They sites that they chose were not able to support the mangroves because of many reasons some being lack of water, a high flow rate, or a sandy soil. The project was first allotted approximately 80-90 million dollars . This is an example of failed nurseries because of high water flow on the left and sandy soil on the right. As you can see even before the tsunami hit the mangrove coverage area was shrinking. This is mainly because of the production of charcoal and aquaculture ponds. As the tsunami hit it caused many problems for the mangroves in Indonesia. One major problem was the amount of sand deposited in the habitats as seen in the picture above. this sand had to be removed because it was changing the way the habitat floor absorbed water and provided less stable ground for trees to be grown on. As can be seen in this picture you can see the extreme damage to the many small costal ecosystems along the coast. The green plants were destroyed by the water and huge waves. This is another picture of the shore as you can see the land is severely deformed and reduced because of the erosion and waves. This is a beach off the coast that had previously been populated by trees but when it went underwater many of them got ripped up and moved elsewhere. These are some of the mangrove trees that were planted and let grow. This was one of the few places the restoration efforts worked.
