Evaluation of the edaphic and water properties of Diu coast (Saurashtra, Gujarat, India) in relation to the population density of Avicennia marina

Abstract The Diu Island is the natural habitat dominated by Avicennia marina mangrove species in southeast coast of Saurashtra Gujarat State India. Since it a famous industrial and tourism place, survival these threatened due to anthropogenic activities. Therefore, conserve , necessary evaluate influence water quality edaphic factors on growth this region. In order study soil water, samples were collected from sediments five different habitats during each season (summer, winter monsoon) physicochemical parameters measured. was influenced seasonal changes change temperature, pH, macroelements (carbon, oxygen, nitrogen, phosphate, sulfur, potassium, calcium magnesium) microelements (zinc, iron, manganese, copper, boron nickel) content which turn increases TDS, TSS, TS, alkalinity, COD BOD water. These correlated with population density plants growing observe its effect habitat. Hence, concluded that there significant changed (site:3 > site:1 site:2 site:5 site:4) at all sites. Multivariate cluster analysis, MDS PCA, identified spatial temporal characteristics suggested site-4 site-5 are more polluted as compared other sites require restoration conservation.
