Study Notes
Mangroves Forest
- Mangroves are plants that grow on the leeward side of a coastal community, tolerating saltwater or salty soils.
Zonation of Mangroves
- The zonation of mangroves from sea to shore includes:
- Red Mangroves
- Black Mangroves
- White Mangroves
- Buttonwood
Red Mangroves
- Have prop roots that stabilize them at sea
- Propagules (young seedlings) drop and float until they stick in the mud and grow into a new tree
- Bark contains tannic acid, which turns reddish brown when it oxidizes
Black Mangroves
- Found in muddy areas with little or no oxygen (anoxic)
- Have adapted by developing vertical roots (pneumatophores) to obtain oxygen
White Mangroves
- Found on the shore
- Have fleshy leaves to help retain water
- Have nectary glands that secrete sugar to attract wasps and bees to defend against predators
Buttonwood (Grey Mangrove)
- Has a reg root system
- Has smooth, thick, waxy leaves that prevent drying out
- In the Bahamas, there are two color forms: Green Buttonwood and Silver Buttonwood
