Sandal wood or "Santalum album" is a parasitic tree having a fragrant and close-grained yellowish heartwood. Sandalwood oil, also known as 'liquid gold,’ is extracted from the roots and wood of sandalwood. This oil is a costly item marketed at a few choosy outlets all over the state. A climate with low rainfall is suitable for the growth of choice sandalwood trees from which good quality oil can be extracted. The 93 km² Marayur reserve forest is believed to have about sixty thousand naturally grown sandalwood trees, of which nearly 2,000 trees had been allegedly plundered in just one year since January 2004, when the last survey was conducted. The auction rate for first quality Marayur sandal is quoted at per kg, according to forest department sources (2004).
