| description | The mangroves of Laguna de Términos, Campeche have been affected by the loss of hydrological connection due to tropical storms and hurricanes. The objective of this study was to evaluate the natural regeneration in a degraded area, after having implemented actions of restoration through hydrological restoration. Three sampling sites with different times of restoration (1-3 years), and a preserved natural mangrove site as reference, were established. The sampling was carried out in the years 2014 to 2015. Forest structure (density, height), survival, growth rate of seedlings and environmental characteristics were measured. The relationship between the vegetation and environmental characteristics was determined using simple linear regressions and multidimensional scaling analysis. To determine the dispersal of seedlings, a mixed linear model of the seedling density vs distance vs time of restoration was generated. The results showed that distance to natural mangroves affects the seedling density. The phosphates concentration is related to survival, while the ammonia and sulfide concentrationis negatively related to seedling density. The actions of hydrological restoration influenced the settlement and growth seedling of mangrove vegetation, therefore natural areas of mangroves and the water reconnection facilitated propagule dispersal towards the degraded areas, highlighting the importance of the inclusion of natural areas within the restoration projects. |

Los manglares de Laguna de Términos, Campeche han sido afectados por la pérdida de la conexión hidrológica durante el paso de tormentas y huracanes. El objetivo de este trabajo fue evaluar la regeneración natural del manglar en un área degradada, después de haber implementado acciones de restauración hidrológica. Se establecieron tres sitios de muestreo con diferentes tiempos de restauración (1 año - 3 años) y un sitio de manglar natural conservado como referencia. El muestreo se realizó en los años 2014 a 2015. Se evaluó densidad, altura, sobrevivencia y tasa de crecimiento de las plántulas, así como las características ambientales. La relación entre la vegetación y las características ambientales se realizaron mediante regresiones lineales simples y un análisis de escalamiento multidimensional. Para determinar la dispersión de propágulos respecto a los manglares naturales, se generó un modelo lineal mixto de la densidad de propágulos vs. la distancia y el tiempo de restauración. Los resultados demostraron que la distancia respecto a los manglares naturales afectó la densidad de los propágulos. La concentración de fosfato se relacionó con la sobrevivencia de las plántulas; mientras que la concentración de amonioy la concentración de sulfuro se relacionaron negativamente con la densidad de las plántulas. Las acciones de restauración hidrológica influyeron en el establecimiento y desarrollo de la vegetación de manglar; por lo tanto, las zonas de manglar natural y la restauración hidrológica facilitaron la dispersión de los propágulos hacia las zonas degradadas, resaltando la importancia de contemplar estas áreas naturales dentro de los proyectos de restauración.
