ILORA
Indian Alien Flora Information Database
The Indian aLien flOra infoRmAtion (ILORA) database is a platform providing ecological, socio-economic, and geographic attributes for the alien plant species of India.
This database, being developed from extensive curation of several Indian as well as global resources, is intended to provide an integrated repository capable of assisting ongoing and upcoming research activities and development of the existing national scenario of alien plant species in India.
ILORA is novel and dynamic in every possible way and therefore, is open for discussions, ideas and assistance from all quarters.
