从古吉拉特邦的丘陵地区、不同气候条件的平原和农业用地进行了密集的实地调查。在古吉拉特邦采集到约23种昆虫，其中8种为：放射状猕猴桃Actiniopteris radiata（Sw.）Link，铁线蕨（Adiantum caudatum L.）A. incisum Forssk.，海金沙（Lygodium flexuosum（L.）开关：凤尾蕨，卷柏Selaginella ciliaris（Retz.）Spring，S. delicatula（Desv. ex Poir.）阿尔斯顿和S. repanda（Desv. ex Poir.）春天作为古吉拉特邦的新分布记录。人为压力的增加、森林生态系统的破坏和基础设施的发展，包括道路拓宽和天然池塘的加深，是陆生和水生蕨类植物多样性下降的其他原因。我们的调查结果表明，E.在野生环境中，矮脚金属已在区域性灭绝，而若不加以妥善保护，其自然栖息地将在短时间内消失。因此，迫切需要通过与国家林业部门合作制定行动计划来进行原位保护。
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.
