Abstract: Coringa wildlife sanctuary is the second largest mangrove formation on the east coast of India with its rich floral and faunal biodiversity.The total number of floral species is composed of 15(8 families and 10 genera) conile fauna represented by 7 diverse groups such as Arthropoda,Mollusca,Pisces,Amphibia,Reptiles,Aves and Mammals.Out of 15 mangrove plant species,Avicennia marina,A.officinalis and Excoecaria agallocha are the most widely distributed species within the sanctuary representing their wide tolerance capacity towards varying salinity ranges.Rhizophora apiculata and R.mucronata are mostly confined to the seaward fringes in this region.During present study,an attempt was made to prepare the species level distributional maps for the above said plant communities with the help of Arc Map 8.1 based on basal area(m~2 per 0.1 hm~2) estimations derived from PCQM(Point Centered Quarter Method).
