| History |
The
earliest classical Sanskrit writers attest the use of 'Birch'
bark for literary purposes. Owing to its papery nature, the
bark (peel), was used in ancient times as a writing material
in place of paper. It was valued for covering umbrellas, hookah-pipes,
for packing, roofing, occasionally as textile and in the manufacture
of Russian leather. 'Kalidasa' mentions it in his dramas and
ethics. The use of this bark was discontinued by Akbar, the
Moghul Emperor, who introduced the manufacture of paper.

 |
| Habitat |
It grows throughout the main Himalayan
range from Bhutan westwards, ascending to an altitude of 4,200
m. Birch forests occur on open exposed tracts which are under
snow throughout the greater part of winter.
