BIODIVERSITY IN RELATION TO MEDI.PLANTS
India – One of the 12 mega diversity regionsF
8% of the global Bd.
45000 plant spp.
16 Agroclimatic zones
10 Vegetation zones
426 unique habitats
# 30 m. (guesstimate) microorganismsF
15 biotic provinces

India- 2 hot spots;
Hot spot concept IS based on endemism- hotspots have high concentration of endemic species facing imminent habitat destruction.
India has more endemic species than other regions except Australia.
315 flowering plant families occur in India out of the 400- and a total of 15300 flowering plant species.

Wait for next issue...more on medi-plants of India.
