This refers to “Phytophysiological studies forests of Chakaria Biggyan Patrika The relationship distribution of ground water seem to the article on mangrove Sundarbans” (Bano 1 & 2 : 17-28). shown between mangrove species table ( Fig. 1 ) does be tenable. Mangrove species grow under tidal swamp conditions. During the high tides water table in tidal swamps occurs over the soil surface. The fall of groundwater table during the low tides under such conditions depends mainly on soil permeability than on elevation of the landform. Soil permeability in Chakaria Sundarbans being very slow, the groundwater table remains almost on the soil surface even during the low tides. No scope, therefore, remains to be confused on the issue at which depth the groundwater table should occur in very poorly drained soils of tidal swamps.
