Plants in the mangrove Part 1
prop root
KNEED ROOTS
AERIAL ROOTSAt the mangrove we learn about why plant need to grow strange roots like prop kneed and aerial roots as the soil they live in are waterlogged and lack of oxygen.
We learn why mangrove environment experience a lot of movement. It is because of the daily tides. A seed planted may be washed away by the tides before it has a chance to germinate and take root. Some trees in the mangrove solve this problem by using a reproductive process called Vivipary.

Plants in the mangrove part 2
SEA HOLLYVivipary is a process where seeds germinate and developed into seedlings while the fruit is still attached to the parent plant. Upon maturity, the seedlings will fall to the ground and lodge into the mud and grow immediately. Those that fall into the water will be dispersed by the tides. Examples of these trees are Rhizophora and Bruguiera.
Mangrove plants are able to survive in salt water because they had their ways to get rid of the excess salt. Some mangrove plants get rid of excess salt in their bodies is to excret it on their leaf surfaces. The salt is then removed by wind or rain. We called these plants the salt secretors. Example of these plants are the AVICENNIA AND SEA HOLLY.
We learn about the factors that affect the oxygen availability and PH of the water. The factor that affect the oxygen availability are the amount of water, plant and organism. The factors that affect the PH are the amount of plant and organism. We also learn what is the long term consequences of water pollution. The consequences are EXTINCTION OF ORGANISM, LESS FOOD AS WATER POLLUTION AFFECT THE FOOD CHAIN AND GETTING DISEASES LIKE CANCER AS WE EAT FOOD THAT IS FILLED WITH TOXIC. So we need to do something about it. Some ways are to tell factories to stop discharging unwanted waste into the sea and not to litter.

Animals, plants and insects found in Sungei Buloh
The 130 hectare reserve, Sungei Buloh Wetland Reserve, is known to be the largest wetland reserve in Singapore that is famous for its mangroves and migratory birds. It is well visited by locals, students and even foreigners that loves nature, learn nature or simply take photos of nature. Despite being covered mainly by mangroves, there were also animals living of simply taking a rest in the reserve.
Some animals, insects and plants found in Sungei Buloh Wetland Reserve:
(Nipah Plam Tree)
(Common Nerite)
(Api Api Bulu)
(Dog-faced Snake)
(Mud Creeper)
(Golden Web Spider)
(Tree Climbing Crab)
(Cicada)
(Barnacles)
(Common Sandpiper)
(Little Egret)
(Giant Mudskipper)
(Malayan Water Monitor)
(Saltwater Crocodile)
(Striped-nosed Halfbeak)

Mangroves in our daily lives
The mangroves are often thought of as a place that is muddy, smelly and full of mosquitoes, snakes and crocodiles. This could not be more wrong! The mangroves are very important to us because these forests have provided us with food, products and even protection from natural disasters! Below are a few uses of the mangroves:
1. Natural coastal protection
Mangroves forests prevent soil erosion along the coast. Roots of mangroves trees hold the soil together thus helping to prevent soil loss. The mangrove act as an natural buffers against strong winds and waves, providing us with protection from natural forces like storms and tsunamis.
2. Nursery for young fish, crab and prawns
The tangled mass of above ground roots and branches provides hiding places for the young organisms, sheltering them from predators and natural forces. The soils and water in the mangroves provides abundant food for them to feed and grow.
3. Useful products from the mangroves
Is charcoal and firewood.
4. Delicious foods from the mangroves
Crab and Attap Chee.
Mangrove Conservation in Singapore
In land scarce Singapore, this big patch of land at the Sungei Buloh Wetland Reserve could be used to build an integrated resort or even a F1 race track. However, it has been set aside as a nature reserve.
5 reasons why Sungei Buloh Wetland Reserve is worth protecting:
1. Education
2. Recreation
3. Research
4. Eco-tourism
5. Mantain Bio diversity
