    Mangroves Mangroves Presentation Transcript

    • Mangroves
    • World Distribution
    • Mangroves
      • Found along coastal areas, especially in estuaries.
      • Grow well in areas with salt and fresh water mix
      • Different species of mangroves use different areas of the tidal zone.
    • Mangrove Importance
      • Areas have murky muddy water that create habitats for juvenile fish, sharks and crustaceans
      • Root systems anchor the soil and prevent erosion in coastal zones
      • Act as wave breakers, protecting coasts and communities from climatic change
      • Create breeding and feeding grounds for many marine animals.
    • Cultural Importance
      • Mangrove areas provide food and shelter for communities. Crustaceans and fish species are caught using traps and nets
      • Tree parts have traditional uses such as
      • Fence building
      • Makes dye for tapa cloths
      • Fish traps
      • Other fishing practices
    • Areas of Issue
      • Pigs free to wander and feed from estuary areas. Pigs increase levels of nitrates and bacteria in the area as well as digging up new mangrove shoots.
      • Deforestation and soil erosion
    • Mangrove Species in Vava’u
      • Red Mangrove (Rhizopora sp.)
      • Prop Roots
      • Small Leaves
      • Whitish Yellow Flower
      • Long pod seed
      • Water/Sea
      • Prop Roots
      • Sprout from very high up in the tree
      • The older the tree the higher the roots are located
      • Roots are very important and have many functions
      • Anchor the plant
      • Absorb minerals
      • Gas exchange O2 and CO2
      • Absorb water from surrounding ecosystem and excludes the salt
      • Leaves are thick and waxy preventing excessive water loss
      • Use photosynthesis to create food
      • Dead leaves fall into water and decay providing nutrients for ecosystem
      • Seed Pod drops when ready
      • Carried by tides and currents
      • Root end bulbous and heavy planting into tidal soil zones
    • Conservation and Sustainability
      • Community ran projects for planting mangroves
      • Creating sustainable use programs
      • Education in schools and community meetings
