Subjected to the incessant swaying of the tides in inter-tropical zones, mangroves are a special ecosystem in which the mangroves, majestic trees with stilt roots, live and develop. Mangroves are kings of adaptation, thriving in a hostile environment: high salinity in warm waters; submerged roots; low soil oxygenation due to silt; unstable soil and sometimes significant sedimentation.<\/p>\n <\/div>\n <\/div>\n <\/div>\n\n <\/div>\n<\/div>\n\n\n

Benefits of mangroves<\/h2><\/div><\/div>\n

Mangroves offer multiple benefits for the climate, local populations and biodiversity.<\/strong><\/p>\n

    \n
  • Mangroves are extremely productive in terms of biomass and store large quantities of carbon in the soil, enabling them to sequester 3 to 10 times more carbon than a terrestrial forest ecosystem.<\/li>\n
  • Barriers to natural disasters (tsunamis, floods, cyclones, etc.) and protection of coastal villages<\/li>\n
  • Shelter and nourishment for marine life, a real asset for local fishermen<\/li>\n
  • Only around sixty plant species can grow in mangroves, but they are the preferred habitat of many animal species that come here to take refuge or nest<\/li>\n
  • A natural filter, they can absorb nutrients and pollutants<\/li>\n<\/ul>\n <\/div>\n <\/div>\n

    Mangrove seeds are called propagules. They germinate directly on the tree before being planted in the soil. A marvel of nature, if a propagule does not take root when it falls from its parent tree, it can change its density to improve its buoyancy and be carried to a favourable rooting place.<\/p>\n <\/div>\n <\/div>\n <\/div>\n\n <\/div>\n<\/div>\n\n\n
