was so greatly infused in the minds and souls of the Bishnois
that in Khejrali village of Rajasthan about 363 young and old
men and women embraced the khejri trees (Prosopis cineraria)
toprotect them from being felled by the king’s men. The local
ruler had ordered the cutting of khejri trees to use them for his
lime kilns as fuel; the Bishnois hugged them and many were
killed in the episode. Later, a temple was built in honour of the
Bishnoi martyrs. One of the leading women of the movement
was Amrita Devi Bishnoi. The repentant king later issued an
edict protecting trees and animals in Bishnoi-controlled lands.
The commoners from a semi-arid zone had understood
the real value of trees. Khejri leaves constitute an important
feed for livestock in a desert region like westernRajasthan, as
they have high nutritional value for camels, cattle, sheep and
goat. A unique feature of this tree is that it yields much green
foliage even during dry winter months when no other green
fodder is available in the dry tracts. People from semi-arid parts
of western Rajasthan encouraged the growth of the khejri tree in
between the cultivable lands and pastures because its extensive
root system helped stabilize the shifting sand dunes. It also fixes
nitrogen through bacterial activity. Besides, villagers usedkhejri
leaves as organic matter for rejuvenating non-fertile soil. Women
use its flowers mixed with sugar during their pregnancy as a
safeguard against miscarriage, and its bark is effective against
dysentery, asthma, common cold and rheumatic arthritis.
Tradition of resistance
The nineteenth and twentieth centuries saw more examples
of resistance against forest cutting. Most of those movements
were largely against unjust colonial forest laws which affected
the livelihood of the local people, especially tribals: the creation
of government-protected forests by the colonial government
was disastrous for the tribals, who were purely dependent on
forest produce. The tribal communities were thus the worst hit
by governmental forest departments.
