Abstract

Life-forms and biological spectrum of the flora of a riverine forest of Song river have been determined. The biological spectrum reveals that the vegetation of this area is thero-phanerophytic. The life-forms observed were therophytes (52.79%), phanerophytes (29.33%), chamaephytes (7.33%), cryptophytes (5.87%) and hemicryptophytes (4.68%). Results show that the percentage of the therophytes in the riverine area is nearly four times higher than those of the same life forms in the normal biological spectrum of Raunkiaers. The higher percentage of therophytes was due to the biotic disturbances like mining, grazing, browsing and lopping of trees.
