Due to mining activities a great loss of vegetation including medicinal plants is inevitable. Northern coal field areas Jayanth coal Block of NCL had been selected for the present investigation. The selected sites are divided into two zones i.e. core zone (mining lease area) and buffer zone (10km radius from mining lease area). A large number of medicinal plants were recorded from the buffer zone in compare to core zone; some of them were, Semicarpus anacardium, Buchnania lanzan, Lannea coromandelica etc. However few species were noticed in core zone viz., Zizyphus jujube, Calotropis procera and Evolvulus alsenoides etc.
