A discovery of mangrove Mayotte

La mangrove à Mayotte

Go and discover the mangrove Mayotte worth the trip! Even if sometimes you plague because it is contaminated by waste from the nearby village, despite the natural cleaning due to tides (important Mayotte: maximum tidal reaches four meters).

Here are some ways to explore the mangroves in Mayotte:

  • back through a small channel to the gates of the village of Bouyouni , by boat, kayak or motorboat (see the IGN map which shows clearly the indentation in the mangroves at Bouyouni)
  • longer walk along the coast in the south, Bouéni N'Gouja (4 to 5 hours walk) where sandy beaches and mangroves alternate, UNIS between a few feet of mangroves where mangroves are sparse,
  • get lost, always on foot, particularly beautiful in the adjacent mangrove bananas near the small village of Dapani.

All of these forays into the world green perched on stilts - no, sorry, on roots - is fascinating and enchanting. Everything is calm, muted. It crosses the periophtalme, kind of small fish amphibious characteristic, the fiddler crab with its huge claw, the Crab-white bird with long beak end, Terebralia palustris, a mollusk cone pointed.

Flora later, the prevailing red mangrove, the white mangrove - another type of mangrove, the land - the yellow mangrove. But he who is first in line, facing the waves of the ocean is the mangrove-flower (Sonneratia alba ", its scientific name). Specifically, the mangrove forest is home Mayotte September species of mangrove. Observe these species of tubes coming out of the sand like a mini-snorkels diving: they allow the roots to breathe.

The mangrove is a tropical forest that flourished between sea and land, in quiet areas and shallow, moving up the rivers until the water is brackish. Its fauna and flora are very specific. It covers an area of approximately 150 000 km ² on the planet, occupies three-quarters of the coastlines and deltas of the tropics and provides excellent protection against erosion and even tsunamis. A Mayotte, tiny island of 374 km2, the mangrove is necessarily close to inhabited areas. And therefore threatened by waste and cuts its mangroves. Who knows that the mangrove is in the public domain and thus "inalienable"?

It is a fragile, very sensitive to the pressure of human activity and pollution. But it is an environment that must be preserved because, beyond the biological interest it represents, plays a dual role in the anti-erosion. On the one hand, the mangrove sediment trap and prevents much going envases the lagoon and smother the reef, on the other hand, it greatly reduces the aggressive action of the waves against the shore. Finally, the mangrove is a nursery for the jack, grouper, shrimp spawn to come to the shelter.
