Abstract

Some alien species result in significant undesirable impacts on the native biodiversity and create serious hindrance to its conservation and sustainable use. Two such species, viz., Alternanthera ficoidea and Pueraria montana var. lobata are found to be spreading vigorously in Doon Valley of Uttarakhand. The former is an herbaceous species seriously infesting the open spaces throughout the Doon Valley, whereas, the latter is a climber infesting entire vegetation in Dehradun area.
