Diversity of Pteridophytes, Distribution, Gujarat stateAbstract
An intensive field survey was carried out from the hilly regions, plains of different climatic regimes and agricultural land of Gujarat state. About 23 species were collected from Gujarat state, from which eight species viz., Actiniopteris radiata (Sw.) Link, Adiantum caudatum L., A. incisum Forssk., Lygodium flexuosum (L.) Sw., Pteris vittata L., Selaginella ciliaris (Retz.) Spring, S. delicatula (Desv. ex Poir.) Alston, and S. repanda (Desv. ex Poir.) Spring. were added as new distributional record for the Gujarat state. Increasing anthropogenic pressure, destruction of forest ecosystem and development of infrastructure facilities including road widening and rainwater harvesting program by deepening of the natural ponds are additional reasons for declining terrestrial and aquatic pteridophyte diversity respectively. Our survey concludes that E. debile is regionally extinct in the wild while Isoetes coromandeliana, will be lost from its natural habitat in short time if not conserved properly. Therefore, there is an urgent need of in situ conservation by developing action plans in collaboration with the state forest department.
