Urgence de conservation dans la Caraibes
Situe au fond de la mer, les pays de la Caraibes se trouvent dans une zone très fragile succeptible a avoir constamment des des cyclones, innondations ect. Avec le changement climatique la mer accelere rapidement et peux faire disparaitre des iles. L'une des meilleurs façon de faire face a cette situation alarmente et de reconstituer les ecosystemes du littoral pour reduire des effets de la mer et les ecosystemes de montagnes pour conserver le sol. Connaitre les plantes natives et leurs fonctions dans l'écosystème est fondamental pour developper des programmes de restauration. Le Jardin Botanique des Cayes se donne pour mission d'inventorier la flore native d'Haiti afin de rendre disponible les informations pour la restauration du pays. Pour ume meilleure comprehension et de partage de connaissances des initiatives mondiale le Jardin Botanique des Cayes membre de l'Alliance des Jardins Botanique pour la restauration écologique.

Collection de semences a Parc Macaya
A significant proportion of Haiti’s native forest has been cleared, firstly for colonial plantations, and more recently for charcoal production. Deforestation has had severe environmental consequences such as soil erosion, flooding and degradation of water resources. Lack of botanical expertise is a major obstacle to restoring Haiti’s forest. Millions of dollars have been spent on reforestation efforts however there has been little long-term success. Cayes Botanical Garden is one of the few institutions in Haiti that hold the botanical and horticultural expertise required to improve the country’s restoration success. In addition to completing baseline floristic surveys, the botanic garden has established native plant plots within its grounds to gather important ecological information that will be crucial to guide future restoration efforts.
Samyda pubescens is example of a native species that has been collected and propagated in the garden. The research has identified that this species is an important food source for Haitian native fauna, but unfortunately forests where it is present have been widely cleared for agriculture. Cayes Botanical Garden is promoting the use of S. pubescens in restoration projects to benefit native fauna, and it is also being promoted in the horticultural trade as it produces an abundance of attractive white and pink flowers.
