Abstract

On September 18th 1989, Hurricane Hugo defoliated large forested areas of northeastern Puerto Rico. In two severely damaged subtropical wet forest sites, a mean of 1006-1083 g/m^2, or 419-451 times the mean daily input of fine litter (leaves, small wood, and miscellaneous debris) was deposited on the forest floor. An additional 928 g/m^2 of litter was suspended above the ground. A lower montane forest site received 682 times the mean daily fine litter fall. The concentrations of N and P in the hurricane leaf litter ranged from 1.1 to 1.5 and 1.7 to 3.3 times the concentrations of N and P in the normal leaf-fall, respectively. In the subtropical wet forest, fine litter-fall from the hurricane contained 1.3 and 1.5-2.4 times the mean annual litter-fall inputs of N and P, respectively. These sudden high nutrient inputs apparently altered nutrient cycling.
