ABSTRACT
Litter fall from a San Andres Island mangrove (12 degrees 32' N, 81 degrees 41' W, Colombian Caribbean coast), was collected monthly (1994-1995) with mesh baskets, keeping results separate for the three species (Rhizophora mangle, Avicennia germinans and Laguncularia racemosa), and taking a sample and a replica per case. Nine sampling sites were selected in two groups of woodlands: one in the inner side behind a sand-bar and the coast road (Mount Pleasant, Salt Creek, Sound Bay and Smith Channel) and a peripheral site, exposed to the waves (BahÝa Hooker-BahÝa Honda and El Cove). Productivity was greater for all species in the inner group, and higher in the rainy seasons. Rhizophora mangle was the only species contributing reproductive components throughout the year.
