Answer: Invasive weed
Notes: Recently, under the three-day “Parthenium Free Pobitora” campaign, 5.2 hectares of Pobitora Wildlife Sanctuary in Assam’s Morigaon district were cleared of the invasive weed Parthenium grass. Parthenium hysterophorus L., also called carrot weed, white top, or congress grass, is an annual plant of the Asteraceae family. This invasive weed is poisonous, aggressive, and harmful to humans and livestock, causing dermatitis, asthma, and respiratory issues. It reduces park aesthetics, blocks pathways, and invades agricultural, forest, and wasteland areas.
