Abstract

Life forms of the vegetation and biological spectrum of the flora of sand bars (islands) of Brahmaputra River have been determined. Results show that the percentage of therophytes and cryptophytes in the newly developed sand bars is nearly three times higher than those of the same life forms in the normal biological spectrum of Raunkiaer (1934). Gradual sedimentation with annual recurrence of flood may be attributed for higher percentage value of therophytes. There is a general progression of plant species resulting from modification of the micro-environment by developing forest vegetation and changes in the soil characteristics with time, which resulted invasion of more phanerophytic plant species in the mature sand bars.
