Producción de hojarasca de los manglares de la Isla de San Andrés, Caribe colombiano

Abstract

Litter fall from a San Andres Island mangrove (12º32’ N, 81º41’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 (Bahía Hooker - Bahía 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
