    Impacts:
    Compétition: Extremely thick mats of P. stratiotes can prevent sunlight from reaching underlying water and aquatic plants (Rivers, 2002).
    Économique/Subsistance: Mats of P. stratiotes can have a negative economic effect by blocking waterways, thus hindering boat navigation and flood control efforts (Rivers, 2002).
    Modification de l'hydrologie: The dense mats created by connected rosettes of P. stratiotes lead to the majority of problems encountered with this species. These mats increase the difficulty of navigation and hinder flood control efforts (Rivers, 2002).
