Pilu (Salvadora oleoides): A protector of Thar desert bio-diversity and fruit crop for commercial promotion

Abstract

Thar desert is the home for many unique crop-plants and the ecosystem farming has evolved to survive them in the harsh conditions. Among the ancient plant species that thrive well in this challenging environment, Salvadora oleoides Decne commonly known as pilu, jaal or meethijaal tree stands out as a vital contributor to the bio-diversity and livelihood protector. This long-lived tree not only plays
a crucial role in supporting ecosystem balance but also serves nutritious fruits to local communities and feed to domestic and wild animals. In recent era, the natural population of this species is decreasing drastically owing to rampant increase in urbanization, expansion of farming area, commercial infrastructures and lack of trees regeneration efforts. Now, this multi-function species is in
IUCN red list of threatened species. Therefore, systematic documentation and technological advancement steps have been taken by ICAR-CIAH to conserve and utilize the Salvadora variability for horticultural promotion.
