One of the original Iranian ecosystem features is from
tropical mangrove forests, a place for multitude of rare species living.
Mangrove forests are incessantly exposed to tide, interface between land and
water, between fresh and salt water. (Tidal currents result from the ebb and
flow of the tide.) . When occurs sea tide flow, trees and their sludge-beds,
come out of the water, and figure as scattered islets.And
during the sea ebb, all the forests disappear beneath the water.
Mangrove is living under stringent conditions,
especially with loose, oxygen-lean , and also a high
salinity soil; however these some peculiar mangrove trees have already adjusted
to these constraints.
Mangrove belongs to the large Avicenniaceae
family, thus named in honour of Avicenna, the great mediaeval Persian
scientist, physician and translator of Aristotle. Grey mangrove, known
scientifically as avicennia marina, whose seeds
germinate and grow up directly on the mother plant, is the most widespread plant
of Iranian mangrove. It's characterized by its great resistance to climate
change and surrounding salinity.
Mangrove tree quickly multiplies and growes up to wooded formations around the shoreline, but
even with all this, mangrove ressources are subjected
to intense exploitation with irreparable damage to this unique environment.
Many species of marine animals, crustaceans,
molluscs, reptiles, birds and even mammals inhabit the iranian
mangrove forest.It's a privileged place for Gulf of
Oman and Persic Gulf fishes,coming ther to spawn.A mangrove frequently encountered fish,called
Periophthalmus, has developped
peculiar fins, giving itself the opportunity to get out of the water and move
on land.It can can survive
for extended periods out of water ! Mangroves ensures important shrimps and
marine turtles stocks.Sea serpents live in mangrove ,some of which very venomous.
But the most interestings
mangrove animals is a variety of migratory birds,
with some of them being in danger of extinction, coming in search of winter to
these mild climate forests. Furthermore, some birds of prey and some sea birds,
endemic in the region, spend part of their lifecycle in the mangrove forest. At
all, more than one hundred species of birds are dependent on mangrove. That's
hundreds of rare species living space and can be regarded as "marine
sensitive areas". This whole region has been classified as "World
Reserve Environment" by IUCN (International Union for Conservation of
Nature).
