ABSTRACT

 

Any plant growing out of place, non useful, unwanted, harmful, often prolific and persistent, or interfering with agricultural operation reducing crop yield is called a weed or floral invasive species. These species grow and flourish in any area, like croplands, roadsides, railway tracks, aerodromes, industrial areas, aquatic systems, forests, grasslands etc with the minimum resources and suitable environmental conditions, being mostly generalist species. Around 45% of the agricultural losses in India are caused by floral invasive species. Apart from their detrimental nature, they are also beneficial to the surrounding environment in numerous ways. They are widely used as human food or cattle fodder, as ornamental plants, add nutrients to the soil and check soil erosion, with wide use in traditional medicine. Many non native invasive species have naturalized in India and are being used for various purposes ranging from medicinal use, attachment to religious sentiments etc. The weed flora of North Eastern India is very diverse. The present study has been conducted in the Ramsar site Deepar Beel Wildlife Sanctuary, with an aim to identify the different invasive species and associated insect pests observed there and the uses of those species as ethno medicines by the local human population .
