Abstract

Status of regeneration of 30 tree species in the Sundarbans has been provided based on data generated from 1203 Temporary Sample Plots (TSPs) during the Forest Resources Management Project (FRMP) Forest Inventory of the Sundarbans in 1996 and 1997. The extents of occurrence of individual species and mean number of seedlings and saplings per hectare have been provided which represents the whole of the Sundarbans. It was found that sundri (Heritiera fomes) constituted 54.92 % seedlings and 28.73 % saplings, while it was respectively 16.23 % and 19.64 % for gewa (Excoecaria agallocha) as well as 16.52 % and 44.36 % for goran (Ceriops decandra). Other species provided 12.33 % seedlings and 7.27 % saplings. Regeneration status of sundri, gewa, goran and amur (Amoora cuculata) of 1996-97 was compared with the data generated in January 2003 from 36 Sample Plots in 10 compartments of the Sundarbans. Comparison revealed that there occurred significant (p=0.05) increase in sundri and amur seedlings in 2003 as compared to 1996-1997 level.
