Abstract Estuaries and tidal creeks,
harboring mangroves particularly, face tremendous anthropogenic pressures.
Expansion of mega cities and the thermal power plants are generally proposed
in the vicinity of estuaries and creek, due to the feasibility of intake and
discharge of water for cooling. Discharges from such developments remain
constant threat of increasing thermal pollution and affecting the quality of
environment. The baseline information on prevailing quality of aquatic
environment comes handy for understanding alterations due to such activities.
Principle component analysis (PCA) revealed that temperature, pH, salinity,
suspended solids, DO, BOD and phaeophytins are
major parameters influencing the creek system. Heated effluents may have
direct and adverse impacts on these parameters, altering biotic constituents.
Hence, periodic and detailed observations are necessary to estimate exact
response of biotic communities to changing environment. The present paper is
based on case study, projecting a power plant in the vicinity
of major mangrove habitats of Dharamtar creek Key
