Phytogeography Practical

Image
Phytogeography is the study of distribution of plant species and elucidation of origin of flora. The word " phytogeography" was derived from two Greek words 'Phyto = Plant' and ' Geografia= Geography '. It is controlled by evolution, climate,  and geographical barriers. Chorology, the mapping of plant boundary, is one of the important core principles of the study of plant distribution to decode the factors like evolution and environmental barriers which shape green footprint of our planet. D.Chatterjee in 1962 divided India into nine phytogeographical regions,viz.:- (1) Western Himalayas,(2) Eastern Himalayas, (3) Indus Plain ,(4) Gangetic Plain ,(5) Assam, (6) Central India, (7) Deccan ,(8) Malabar ,and (9) Andaman and Nicobar Islands. Geographical location,Type of vegetation, average rainfall, altitude, and two major plants of each regions are listed below:- Western Himalayas: Kashmir, Northern Punjab,Kumaon ranges of Uttranchal Subtr...
