Variations in Plant Zonation and Cover as Indicators of long-term changes in soil conditions: a case study in a mediterranean coastal salt marsh

José Álvarez-Rogel, María Nazaret González-Alcaraz



This study summarizes the changes (1991-2004) in plant distribution and cover in relation to soil factors in a salt marsh impacted by surplus of water from agricultural origin. An elevation of the groundwater level was observed, which led to a homogenization in the saline gradient. The changes were reflected in a shift in vegetation distribution which included the disappearance of most of the zonation observed in 1991.
