La Martinique abrite l’une des biodiversit\u00e9s les plus riches de la Cara\u00efbe, avec une flore de pr\u00e8s de 3 000 esp\u00e8ces et une faune end\u00e9mique d’une grande singularit\u00e9. Mais cette richesse est sous pression. Parmi les menaces les plus document\u00e9es figure l’invasion d’esp\u00e8ces exotiques envahissantes (EEE), qui comptent aujourd’hui parmi les premi\u00e8res causes d’\u00e9rosion de la biodiversit\u00e9 mondiale \u2014 et la premi\u00e8re cause document\u00e9e de disparition d’esp\u00e8ces selon l’UICN. En Martinique, environ la moiti\u00e9 des esp\u00e8ces v\u00e9g\u00e9tales pr\u00e9sentes sont d’origine exotique, dont plus d’une centaine class\u00e9es comme envahissantes.<\/h2>\n

Un fl\u00e9au aux multiples visages<\/strong><\/h2>\n

Sur le plan v\u00e9g\u00e9tal, des esp\u00e8ces comme le Miconia calvescens \u2014 surnomm\u00e9 \u00ab cancer vert \u00bb en Polyn\u00e9sie pour sa capacit\u00e9 \u00e0 former des couverts monosp\u00e9cifiques \u2014 ou la jacinthe d’eau qui colonise rivi\u00e8res et retenues constituent des menaces majeures pour les habitats indig\u00e8nes. La DEAL Martinique a mis \u00e0 jour en 2025 son guide des esp\u00e8ces alternatives pour les am\u00e9nageurs, visant \u00e0 promouvoir la flore native. C\u00f4t\u00e9 faune, la petite mangouste indienne, introduite au XIXe si\u00e8cle pour lutter contre les rongeurs, s’attaque aujourd’hui aux pontes de trois esp\u00e8ces de tortues marines prot\u00e9g\u00e9es : la tortue luth, la tortue imbriqu\u00e9e et la tortue verte.<\/p>\n

Le projet REFEM : mieux conna\u00eetre pour mieux prot\u00e9ger<\/strong><\/h2>\n

Lanc\u00e9 en juillet 2024 pour une dur\u00e9e de deux ans, le projet REFEM \u2014 port\u00e9 par l’Office fran\u00e7ais de la Biodiversit\u00e9 (OFB) et l’ONF, avec le soutien financier de la Fran\u00e7aise des Jeux \u2014 vise \u00e0 mieux comprendre la pr\u00e9sence des vert\u00e9br\u00e9s exotiques envahissants au c\u0153ur de la Montagne Pel\u00e9e et des Pitons du Carbet, site qui couvre pr\u00e8s de 140 km\u00b2 de for\u00eat end\u00e9mique. Le Parc Naturel R\u00e9gional de Martinique (PNRM) a pour sa part d\u00e9ploy\u00e9 une brigade d\u00e9di\u00e9e \u00e0 la lutte contre les EEE prioritaires, ciblant notamment le Miconia calvescens et l’iguane ray\u00e9, dont l’impact sur les esp\u00e8ces end\u00e9miques est av\u00e9r\u00e9.<\/p>\n

En bref :<\/strong><\/p>\n

la lutte contre les esp\u00e8ces exotiques envahissantes mobilise d\u00e9sormais un front commun d’acteurs, DEAL, OFB, ONF, PNRM, CBN, autour d’une strat\u00e9gie qui articule connaissance scientifique, action de terrain et sensibilisation du public. Un combat de longue haleine pour la biodiversit\u00e9 unique de l’\u00eele.<\/h3>\n","protected":false},"excerpt":{"rendered":"
