We began work in Rao Jodha Desert Rock Park in 2006 to try and restore the natural ecology of a large, rocky wasteland next to Mehrangarh Fort in Jodhpur. It had suffered years of neglect and was overrun by invasive Prosopis juliflora whose seeds had been broadcast from the air in the 1930s. The challenge was to eradicate P. juliflora and understand how native rock-loving plants would adapt to conditions here. In 2011 we created a visitors centre and trained some Naturalist guides to take visitors around. We publish small field guides on topics of interest and have geological exhibits in the visitors centre.
