BIOLOGICAL SPECTRUM OF HORISTIC COMMUNITY IN DAPOLI TAHSHIL OF RATNAGIRI DISTRICT (M.S.)D.N. Mokat and B.B. Jadhav
The biological spectrum of an extensively distributed area under tropical monsoon climate was studied and a total 258 species, which are distributed among 74 families, were recorded.The spectrum includes Phanerophytes (47.20%), Chamaephytes (5%), Hemicryptophytes (1.16%), Cryptophytes (8.14%) and Therophytes (38.37%). Leguminoceae was the largest family with 24 species followed by Malvaceae and Poaceae with 13 species. Out of the total species, 58.92% species are propagated by seed, 9.69% by vegetative method and 29.84% of species adopted both sexual and vegetative methods of propagation. Phenerotherophytic communities occupy the area. Occurrence of therophytes as successive invaders is assumed due to extensive biotic disturbances. In the study, almost all species occur in wild state.
