Mangroves native environment

Extracts from this document...


Mangroves Introduction: Mangroves are tropical shrubs and trees that can grow in salt water. They grow along muddy beach shorelines which is called tidal zone. Mangroves grow on salty water unlike other trees on the land. They have prop roots which go underwater during high tide however the roots are out on the surface of the land during low tides. Mangroves are important because they trap waste and mud, evening out the shore environment and clarifying closest open water. Mangroves need high temperature, variable salinity, changing aerobic and anaerobic conditions, occasionally wet and dry, unshifting and shifting substratum. On Wednesday, 5th November we went to carry out an ecological survey of the Mangrove community at Sai Kung, Tolo Harbour. We reached at the Mangrove beach at approximately 10.00am and at that time the weather was quite warm. We chose a suitable site from the back of the beach to work downwards on finding information on plants and animals that live in that particular community. ...read more.

Some species and plants have been distributed along the area however some species and plants have been gathered in certain areas of the beach. Species that were gathered around certain transect were Barnacles, Rock oysters, Terebralia and Sesarmid crabs. Plants that were planted along certain transects were Kandelia and Lumnitzera. Other plants and species were scattered around as seen from the table and graphs. Firstly, from Graph 1, you can see that the majority of plants there were in the mangroves beach were Kandelia. ...read more.


From zero to twelve meters, the soil was hard and stony. It was not very wet because it was at the back of the beach, not near where the water was. The soil was light in colour and there were a few trees along the passage, so there was space to walk. However, from twelve to forty-two meters, there were more and more plants in the way and it was harder to walk through one selected passage. At that district, there were the main plants and animals which are Terebralia and Kandelia as well as other species and plants (see in Graphs). From forty five meters onwards, there was the beach, where the change ground leveled off. The ground was very muddy and the soil was wet. It was more grey and dark brown. There were lots of snails around the beach as well as rock oysters. Overall, from my results, I think that the species and plants have been well adapted to their surroundings by balancing the mangroves eco-system.
