Abstract
    Muthupet mangrove ecosystem (10° 25' N and 79° 30' E) is located at the southem end ofthe Cauvery delta on the east coast of India. The swamp is characterized by the presence of only 4 species of exclusive mangroves namely Avicennia marina, Excoecaria agallocha, Aegiceras corniculatum and Acanthus ilicifolius . Community structure analysis carried out at four randomly selected quadrats showed that the relative density, relative dominance, relative frequency and importance value of A. marina was relatively higher than for the other three species. Hence, Muthupet mangrove ecosystem is characterized by the mono-specific dominance of A. marina. Earlier palynological studies indicate that species like Rhizophora were present in this swamp some 200 years ago. It is believed that the past management practices together with the present poor scientific policy of the decision makers and harsh environment conditions may be considered as a few factors responsible for the disappearance of Rhizophora from this mangrove swamp.
