The economically important, naturally occurring species of the Indian desert was surveyed on the basis of the perception of local plant scientists. About one-fourth of the total 84 taxa were seen to be facing varying stages of risk. Of these, 17 species and 8 botanical varieties are endemic to Indian desert. Eighteen species in Bikaner, 21 in Jaisalmer and 19 in Jodhpur divisions were reported to be at risk. Factors responsible for the loss of species diversity have been discussed and appropriate strategies have been suggested for their conservation.
