Background
• Over seven thousand medicinal plants in India being used in indigenous medical systems like Ayurveda, Sidhha, Unani, and Tibetian
• Traditional Knowledge regarding these plants is increasingly realized and being put to use in modern medicine
• Plant Populations are depletingoHabitat fragmentationoHigh volume tradeoUnregulated destructive collection
• Need conservation efforts

Methodology
• Data collected from Herbaria, Literature and Field Surveys• Data sources maintained for later references• Literature Data tabulated at three levels:
o Countrieso Districts and States within Indiao Precise locations (which could be converted in Latitude and
Longitude for plotting)• Three types of maps generated:
o World maps depicting countries presento District / States within Indiao Detailed regional maps superimposed with Rainfall, Altitude
etc.• Used MapInfo for map preparation

Conclusions
• Understanding distribution and eco-climatic limits help in formation of conservation strategies
• Causes for reduction can be diagnosed looking at availability of species in historic and current time
• Provides insights into the regions where conservation measures need to be initiated
• Using the historical literature and collection records, has lead to rediscovery of plants
• Area for species recovery programs can be identified• Serves as an important tool for conservation planners

Future Work
• More data on abundence levels might be added to open up more analysis possibilities
• Data collected can be used for Niche Modeling of the species, which would provide more insights into conservation planning
• Make it available on open source and web based GIS platform
• Opportunities are infinite …
