Mangroves provide a variety of environmental services: they are areas of food, shelter and growth of juvenile crustaceans and fish fry, so that sustain much of the fish production, have high aesthetic and recreational values, act as natural systems and flood control and hurricane barriers against intrusion, control erosion and protect shorelines, improve water quality by acting as a biological filter, contribute in maintaining natural processes such as responses to changes in sea level, maintain sedimentation processes and serve as a refuge for flora and fauna, among others.

Une barque, un catamaran,
Embarquons pour l'ile sous le vent,
Le Cuba Libre, la musique,
Un cigare... c'est ça les tropiques !
A boat, a catamaran,
Let us embark for the island under the wind,
Cuba Libre, the music, a cigar...
that's it the tropics !
Approximate translation, corrections welcomed... Thank you in advance
Along a river near my house. Unfortunately the water is full of sharks.
What a fascinating tree! The Red Mangrove has viviparous "seeds" called propagules, which can become fully mature plants before dropping off the parent tree.
I made an early morning bike ride to get to this spot. And then on the way back to my campsite, a most unlikely but gratifying thing happened. I encountered a former student of mine. There I was over 600 miles from home and I ran into a young man who had been in my high school chemistry class 15 years ago back in Georgia. He now lives in south Florida and was camping with his wife and family and some friends.
One from the archives. It was the sparkle of the sunshine that really captured my eyes.
these are local children of the island.couldn't help but be awed with their playground.
There wasn't a lot of colour in this mornings sunrise, but some very interesting cloud formations. This was taken about 45 minutes after sunrise.

@ Parguera PR, Cloudy days are very interesting for pictures!!
Mangroves are various kinds of trees up to medium height and shrubs that grow in saline coastal sediment habitats in the tropics and subtropics – mainly between latitudes 25° N and 25° S. The word is used in at least three senses: (1) most broadly to refer to the habitat and entire plant assemblage or mangal, for which the terms mangrove forest biome, mangrove swamp and mangrove forest are also used, (2) to refer to all trees and large shrubs in the mangal, and (3) narrowly to refer to the mangrove family of plants, the Rhizophoraceae, or even more specifically just to mangrove trees of the genus Rhizophora.
The mangrove biome, or mangel, is a distinct saline woodland or shrubland habitat characterized by a depositional coastal environments, where fine sediments (often with high organic content) collect in areas protected from high-energy wave action. Mangroves dominate three quarters of tropical coastlines.The saline conditions tolerated by various mangrove species range from brackish water, through pure seawater (30 to 40 ppt), to water concentrated by evaporation to over twice the salinity of ocean seawater .
A lone mangrove tree struggles to establish its place in the waterway.
There are about 80 different species of mangrove trees. All of these trees grow in areas with low-oxygen soil, where slow-moving waters allow fine sediments to accumulate. Mangrove forests only grow at tropical and subtropical latitudes near the equator because they cannot withstand freezing temperatures.
Many mangrove forests can be recognized by their dense tangle of prop roots that make the trees appear to be standing on stilts above the water. This tangle of roots allows the trees to handle the daily rise and fall of tides, which means that most mangroves get flooded at least twice per day. The roots also slow the movement of tidal waters, causing sediments to settle out of the water and build up the muddy bottom.
Mangrove forests stabilize the coastline, reducing erosion from storm surges, currents, waves, and tides. The intricate root system of mangroves also makes these forests attractive to fishes and other organisms seeking food and shelter from predators.

From the same night as my last post. These red mangroves seem to be a dwarfed by growing a little off shore and have no soil, digging into the limestone and coral instead.
Thanks for all thecomments on the last!

This is a shot I took a while back. I have planned to go back down the Westernport bay to get some shots of the mangroves but haven't had a chance or timing the high tide. the day I took this shot It was a little windy.. not the best conditions when trying to photograph a tree, but I do really like the spikes under the mangrove. looks very lethal.
