Thar Desert has
great diversity in vegetation. As many as 700 species
of
plants are found in the area, of which 107 are of grass alone. These plants are
deep-rooted and tenacious enough to withstand extended droughts and yet
efficient enough to gain biomass rapidly during a
favorable season. The local grasses are generally prolific seeders, and most of
the species are palatable, fairly nutritious and rich in minerals, including
trace elements.
The
Thar Desert endowed with some of the best breeds of livestock in the
country. Nearly 50 per cent of the country's wool is produced in
Rajasthan, and the area has been the main supplier of bullocks to the
North.
By and large, land-use in the Thar is dependent on rainfall. In good
rainfall years, large areas are cropped, cattle thrive on extensive
pastures and substantial amounts of hay are stored for future use.

Rainwater is
stored in ponds and underground tanks. As rainfall is very erratic, a pattern of
mixed farming has been developed in which human and animal populations benefit
from each other.
