Salvinia molesta (salvinia)

Salvinia molesta, commonly known as giant salvinia, is a fast-growing aquatic fern native to South America. It forms dense mats on water surfaces, which can block sunlight, reduce oxygen levels, and disrupt ecosystems. This invasive plant spreads easily through fragmentation and can clog waterways, affecting water flow, irrigation, and native aquatic life. It thrives in warm, nutrient-rich waters and is difficult to control once established. Managing Salvinia molesta involves mechanical removal, herbicides, and biological control methods to prevent environmental and economic impacts.
