Paper reports on a detailed analysis of a mangrove forest of Krishna Wildlife Sanctuary , Andhra Pradesh. The study was conducted during July 2002 , and the vegetation was sampled through random sampling method. This type of study is done for the first time in Indian Context. The result shows that Avicennia officinalis , Rhizophora apiculata , Agiceras corniculatum , Bruguiera cylindrica , Ceriops decandra and Excoecaria agallocha are the common species with sufficient number of the individuals. Good regeneration of all these species were also recorded. Some areas viz. , Nachugunta beat and Machlipatnam , support sparse vegetation composed of helophyte species i.e. Suaeda nudiflora , S. monoicea , S. maritima , Salcorina brachiata , Helotropium curassavicum and grasses Aeluropus lagopoides , Sporobolus verginicus , Spinifex littoreus and Zoysia mortella. Few species of creeper Ipomoea pescarpae , herb Launea sarmentosa and hedges Cyperus arenarius and Fimbristylis polytrichoides have also been recorded. In newly formed silt deposits in inter-tidal regions , the grass Porteresia coarcata found growing as pioneer species. A pure stand of Prosopis juliflora spread over 6km area , where the seeds were brought by 1977 cyclone. In Sorlagondi beat well grown trees of Salvadora persica were also noticed.

Interesting to mention here the occurrence of seven endemic species viz., Cycas beddζmei, Shorea tumbuggaia, Boswellia ovalifoliolata, Pterocarpus santalinus, Terminalia pallida, Syzygium alternifolium and Pimpinella tirupatensis. Study was conducted in the year 2002, and the vegetation was sampled through random sampling method. The result presented in four groups. In Group 1: Hardwickia binata and Pterocarpus santalinus were main dominating species having density of 183 trees/ha and 133 trees/ha. The total trees, saplings and seedlings density of the whole stand was 667 trees/ha, 2167 saplings/ ha and 483 seedlings/ha, respectively. In Group II the structure of the tree component consisted 27 species of over 10 cm dbh. The trees, sapling and seedlings density of the whole stand was 551, 1274 and 980 individuals/ha respectively. In Group III The community consisted 40 species of which two, Ehretia laevis and Pterocarpus santalinus were dominant species. The total sapling and seedling density was 1087 and 847 individuals/ha.
