Nativity of tree species - (Jul/10/2010 )

Dear friends,

Could anyone help me how to arrive at NATIVITY of a tree species? Also I find in research articles "nativity range". For e.g., it reads that the nativity range for Azadirachta indica is India and Burma. My understanding on nativity of a species is very vague. Could anyone kindly help?

With Best Regards,
Rajasekar

Nativity is a bit of an obscure term nowadays, you could try "indigenous range", or even just "native range".
