The mangroves of the Bay Islands accounting for 18% (383 km2) of the total Indian mangroves were adversely affected by the December 2004 tsunami. Changes in topography, salinity and massive water inflow have led to extensive soil degradation and associated nutrient losses in these mangroves. The major
aim of the study was to determine whether the December 2004 tsunami had any effects on soil physicochemical (pH, electrical conductivity of saturation extract (EC), clay, cation exchange capacity (CEC), organic carbon (OC), total N (TN), Bray phosphorus (P), exchangeable cations (Ca, Mg, K and Na)) and
biochemical/microbial parameters (Microbial biomass
