In the present study, the diameter of the mature Drosera rosette had ranged from 1.4 to 2.1 cm, while for juvenile plants rosette diameter was 0.9 to 1.6 cm. Sites are subject to persistent anthropogenic disturbance like grazing, soil removal, thatch collection, annual weeding growth like Eupatorium and Lantana spp., use of agrochemicals, habitat destruction during fishing, are the primary threats to persistence and survival of the species. Therefore, population of this natural growing plants and habitat should need to be conserved before this plant face the day by day global change.
