La alteración de los flujos de agua y la consiguiente hypersalinización causó la muerte de casi el 70% de los manglares en la CGSM, Colombia. Los esfuerzos realizados para rehabilitar el ecosistema se han hecho a través de la construcción de canales de agua dulce. Alteration of water flows and consequent hypersalinization caused the death of nearly 70% of mangroves at the Cienaga Grande de Santa Marta, Colombia. Efforts to rehabilitate the ecosystem have been made through the construction of freshwater channels. Mangrove recovery was observed along a freshwater channel and at a small lagoon behind the beach ridge. Factors identied in this study influencing mangrove regeneration are: salinity of surface water, duration and height of flooding, leaching property of soils, dispersal of propagules and presence of fertile trees. Besides mangrove regeneration, a notable extension of freshwater plants was observed in the channel. Trace metal concentrations in sediments from the Magdalena River and its area of in¯uenc
