ZONATION MANGROVE FOREST

Mangrove forests are forests that grow in tidal areas . Understanding and definition of mangroves is often interpreted to all types of mangrove plants . This area periodically inundated , including existing plants in the region also periodically submerged . To be able to grow in the tidal area of ​​the plant must be able to adapt to the salt content ( salinity ) is high . In addition it has a root modifications provide opportunities for the plants breathe in waterlogged conditions . Modification on plant roots is often called the root of breath or the term " pneumatofor " .

In the mangrove forests grow several types other than Rhizophora sp , for example Sonneratia sp , Bruguiera sp , Avicennia and Ceriops sp sp . Usually there is a mangrove forest in the growth zone , each type with its own growth areas according to habitat .

Growth zoning division is often divided by the area of inundation and plant species that grow in the area . For example, according to the flooded areas are classified into 3 zones : Zone of Proximal , Distal Zone and Zone midle .

• Proximal zone is a zone close to the sea or the leading zone . This area is usually found on the kinds of Rhizophora apiculata , Rhizophora mucronata , and Sonneratia alba .
• Midle zone is a zone that lies between the sea and the land or mid zone . Usually found types : caseolaris Sonneratia , Rhizophora alba, Bruguiera gymnorrhiza , Avecennia marina , Avecennia officinalis and Ceriops tagal .
• Distal zone is a zone that is furthest from the sea or backward . Commonly found in this region Heriteria littoralis types , Pongamia sp , sp Xylocarpus , Pandanus sp , and Hibiscus tiliaceus .

Many people who want to make a mangrove planting in the area but often fail due to insufficient understanding of the characteristics and mangrove habitat itself. How mangrove plants that can grow with and what are the factors that influence it , to know and to learn as possible .

Several factors can affect the growth of mangrove such as ocean waves are not too big , it is necessary for mangrove plant species can be taken root . Further requires Salinity ( salt content ) is high because it is a meeting area and fresh sea water . There are deposits of mud on the coast , as well as having a wide tidal areas . That's some of the factors supporting the growth of a mangrove species in an area.

The supporting factors must be considered in order to properly planting and rehabilitation of mangrove areas can be managed . Selection of the right type of habitat in accordance with zoning and also help determine the percentage of live and success of the plant .
