Control of Pistia stratiotes in Andalucía (Spain)
Pistia stratiotes (Araceae), a tropical aquatic-floating weed that invades channels and wetlands, has now been recorded throughout 35000 m² in Andalucía (near Doñana Natural Park). Given the risk this species represents for native wetlands, a control program has been initiated based on the physical removing (by hand and machinery) and specific application of a low-impact herbicide if necessary. The eradication is being undertaken within the Andalusian Program for the Control of Invasive Exotics (Plan Andaluz para el Control de las Especies Exóticas Invasoras) (Ortega et al., 2006).
