MANGROVES OR MANGAL
• “Rainforest by the Sea”• Associations of halophytic trees,
shrubs or other plants growing in brackish to saline water
• Found on tropical and subtropical coastlines
• Inundated daily with sea water but protected from heavy waves
• Limited by frost
ADAPTATIONS
• Salinity Control – salt exclusion or secretion
• Viviparous seedlings
• Prop roots and pneumatophores
SALINITY
• Facultative halophytes – found over a wide range of salinity; 10-60 ppt
• Competitive advantage over freshwater species
• Survive wide annual fluctuations
MANGROVE COMMUNITY TYPES
Fringe Mangroves
•Overwash island
•Shoreline
