A detailed survey was carried out from November 2007 to February 2013 along the Peninsular India, North eastern India and Andaman Islands and conservation status of Indian Pandanaceae species was determined following IUCN Red List Categories and Criteria (2001). The assessment indicated that, among the 19 Indian Pandanaceae members, 6 species are falling under threatened category. P. palakkadensis and P. mangalorensis falls under Critically Endangered, P. unguifer and P. martinianus under endangered and P. diversus and B. thwaitesii under vulnerable category. P. furcatus, P. unipapillatus, P. odorifer, P. kaida, P. leram, P. nepalensis and B. foetida, F. sumatrana and F. rigidifolia fall under Least Concern category. P. emarginatus under Data Deficient category and P. amaryllifolius, P. sanderi and P. dubius as exotic species. Based on our study, we recommend 6 threatened species to include in the IUCN Red List.展开更多
