ABSTRACT

Variation in soil properties and heavy metal content and their distribution along the tidal
gradients of coastal saline mudflats, supporting natural vegetation of S. brachiata at seven different
such sites in Gulf of Khambhat of Coastal Gujarat (Western India), were investigated. Concentration
of organic carbon (OC gkg-1) was recorded high at Kotada site, while the pH and salinity remained
more at Diu site. Fe, Mn, Ni and Zn were concentrated in sediment deposits in all Salicornia
growing sites, thereby indicating restricted movement of metals due to the presence of Salicornia
vegetation. Results also revealed that soil pH of highly saline mud flat supporting Salicornia
plants had a negative correlation with most of the heavy metal elements. Under saline condition,
all the heavy metals are found positive and Cu had significant and positive correlation with most
of the elements.
