The cortadeira, known as pampas grass, has already been identified in at least 208 municipalities in mainland Portugal and is among the invasive plants with the widest distribution in the country.
Experts warn about the environmental risks associated with its uncontrolled expansion. Beyond the impacts on biodiversity, there are also concerns related to the allergic potential of the plant's pollen.
The experts criticize the lack of measures by the authorities to stop the expansion of the species. The situation is described as an invasion already established in Portuguese territory.
