Four pyrophytic pteridophytes in the Chir pine forest of Kalidhar forest range in Shiwaliks of North West Himalaya in Indian Himalayan region

Fire always plays a significant role in the secondary succession and maintenance of various communities or ecosystems on earth, like grass community, understorey community in a forest and on a large perspective forest ecosystem. Vascular cryptogams form an important group of plants that is recovered very rapidly after the fire events. This is perhaps due to their rhizomes lying below the ground surface, which are able to evade the fire stress. Current study deals with presence of four pyrophytic (fire–tolerant) pteridophytes in Kalidhar forest range at Jammu district.
