A study was conducted to estimate the distribution and diversity of tree species in Chilika lake ecosystem, the largest lagoon in Asia. The present study was conducted in 2014 by laying out quadrats of desired size to estimate the diversity of tree species in three of the four ecological sectors namely northern, central and southern sector. A total of 69 tree species representing 57 genera and 33 families were recorded from the three ecological sectors of Chilika. Among the three ecological sectors, northern sector was found superior in terms of species richness and diversity with 46 tree species per hectare of area. The total dominance of northern sector was also highest i.e. 36.35m2/ha. Among the species documented, maximum value of Importance Value Index (IVI) was reported in Teak (21.69) followed by Casuarina (19.02) and Sal (14.95) respectively. The Shannon-Weiner Index value was found in the range of 1.5 to 3.5. It was observed that species diversity in the ecological sectors is substantially influenced by intensity of human interference in and around them. The occurrence of major portion of northern sector within natural forest boundary might have contributed to enhanced species diversity.
