Measurement of Ethnic Knowledge Associated with Semecarpus anacardium L. f. -- A Rare and Endangered Ethnobotanical Plant of Jharkhand, India

摘要

During the observation on ethnobotanical wealth used by the tribal people in their day to day needs, healthcare and socio-religious ceremonies of Jharkhand state of India, it was observed that due to the depletion of plants, the ethnic culture and associated knowledge system related with the plant species is also being lost. It has also seriously affected the oral traditions and knowledge of the tribal communities. To assess the above problem several indices like ‘Knowledge frequency’, ‘Plant-lore Index’ and percentage of ‘Community knowledge loss’ were developed to measure the knowledge status of tribes associated with Semecarpus anacardium L.f .
