The post hurricane successional process included a great deal of resprouting of pre-existing individuals and the current state of the forest includes a low but very dense canopy, suggesting that competition is entering an intensive phase. Specific growth rates between the time of the hurricane and the present thus represent establishment or regenerative growth rates and provide an indication of whether or not distinct regeneration niches exist. Three distinct patterns of growth rate seem apparent, fast-growing heliophyles (eight species), slow-growing resprouters (nine species), and Vochysia ferruginea, which seems to have a special pattern.
