Are duckweed an invasive species

Duckweed can be considered an invasive species in certain regions where it proliferates excessively, causing ecological harm. Its rapid growth can lead to dense mats that block sunlight, deplete oxygen levels in water bodies, and disrupt aquatic ecosystems by outcompeting native plants. While duckweed is beneficial in controlled environments for water purification and as a food source, its unchecked spread can negatively impact biodiversity and water quality in some areas.
