IS MANGROVE FOUND ?
trees are found along muddy sheltered
shoreline free from ordinary strong
winds and currents( e.q, mounth
of big rivers). They can also grow
on sandy and rocky shores, coral
reefs and oceanic islands. While
brackish water is ot essential fro
mangrove's growth, it thrives if
there are pelentiful supplies of
fine sidements and fresh water.
morhological characteristic of mangrove
species appear in their root system
and fuits as elaborated below.
of mangrove habitat becomes anaerobic
(air free) when it is under water.
Some species develop a typical root
system called aerial roots suitable
for anaerobic soil conditions.
species produce fruits usually dispersed
by water. The fruits take several
shapes such as cylindrical. round,
and bean- like.
