Question

Why Eicchornia crassipes is called as an invasive plant??

Answer 1

An invasive species is an animal or plant which is introduced into a new area where it does not occur naturally. If the introduction occurs without the accompaniment of its pests and diseases that keep the species in check (under control) in its natural range and if it is able to survive, establish and spread thus causing damage to biodiversity, peoples’ livelihoods or development, it is called “invasive”.
Water hyacinth, sometimes called the World’s Worst Water Weed, is becoming invasive in the Lake Tanganyika basin and on the shores and wetlands of some parts of the lake.Water hyacinth (Eichhornia crassipes) is an exotic free-floating aquatic plant from the Amazon River basin in tropical South America. The dark green, shiny leaves have expanded hollow stems (petioles) that enhance its ability to float and can extend to 2 m above the water level. Below the water surface, there are root-like structures (rhizoids) which balance the plant and keep its aerial parts upright while taking up water and some nutrients. It reproduces through flowers and seeds (which can remain viable for up to 15 or more years) and has vegetative propagation by its stolons which are lateral extensions from the main plant which produce new plants which eventually leave the “mother plant”.
