DEGRADATION AND DESTRUCTION OF SEAGRASS BEDS
Importance
>Stabilizes sediments (especially important during storms and hurricanes)
> Slows down water currents ( which helps with anchoring their roots and nutrient intake)
Protection against coastal erosion (minimising wave energy and stabilizing sediments)
Threatened by:
•Human pollution results in eutrophication
•Excess suspended sediments which reduce light
•Damage to leaves, stems and roots by boat propellers, trawlers' nets and dredging
•Mechanical destruction for construction of marinas and aquaculture facilities.
MANGROVES
White mangrove- Laguncularia racemosa
Ultrafiltration- this process allows mangroves to survive in waters with a high salt content by filtering the salts out with their roots.
They are then excreted via specialised glands in the plant.
Mangroves also filter pollutants and other harmful or unwanted substances out of the water.
TYPES OF MANGROVES- the main difference between these mangrove species is the places in which they grow on the coast. Their locations also influence some of their physical characteristics.
