The physiognomy of Caribbean dry forest is shorter, denser and contains a greater proportion of multi-stemmed trees than other neotropical dry forests. Our previous research, conducted after Hurricane Georges in 1998, has shown that dry forest trees sprout near the base following hurricane disturbance, even if the trees have not incurred structural damage. However, for these hurricane-induced sprouts to contribute to the physiognomy of the forest, they must grow and survive. We followed sprout dynamics and stem mortality on 1,407 stems from 1998, after Hurricane Georges, until 2005. The number of surviving sprouts and the proportion of sprouting stems decreased …

Hurricane Georges passed over mature dry forest near Guánica, Puerto Rico in September, 1998. The trees of the dense, short-statured Guánica Forest have a multi-stemmed structure unique to the West Indies in the neo-tropics, a characteristic that has been difficult to explain. Following the hurricane, we measured sprout development below breast height on 1407 stems to assess how response to hurricane disturbance may influence dry forest structure. Basal sprouting increased 8-14 fold after Hurricane Georges. Basal sprouting was found on al- most 68% of damaged stems and, notably, on about 32% of undamaged stems. Basal sprouting was found in all …
