Résumé : Madagascar is one of the countries richest in biodiversity. The mangrove swamp is part of this biologic diversity of which the West part of Madagascar possesses the majority of it. Threats as the climatic changes and the pressures anthropic weigh on the mangrove swamps. Our objective fundamental of this survey aims to promote the restoration of the mangrove swamp on the dynamism of growth of Avicennia marina in Bombetoka Belemboka Mahajanga. Two hypotheses have been proposed, on the one hand the restoration of the mangrove swamp on the dynamism of growth of Avicennia marina, and on the other hand the creation of a livable habitat to the species associated to the profit fairness of the riparian populations. Of this fact, some investigations ethnobotaniquec has been done by the local population and also a follow-up of culture on the 4 substrata. The data are treated statistically on Anova and Kruskal - Wallis. The gotten results showed that the rate of germination is better in the A1 substratum (94%), A2 (87%), and A3 (86%) on the other hand in the A4 substratum (71%) the death rate is observed strongly. For the growth of the Avicennia marina species, there is a meaningful difference between the different substrata via the length, the width, the number of the leaves and the height, the diameter of the young plantations. The restoration and the management will be necessary to consider the perpetuation and the survival of the rest of our inshore resources for the future.
