Lantana camara is an invasive alien plant species native to Central and South America. Introduced in India in the 18th century, it has aggressively spread across tropical regions, displacing native flora by releasing allelochemicals and forming dense thickets. It poses a threat to biodiversity but also holds potential for socioeconomic use through biomass-based products like fuelwood, furniture, and organic compost.
