pampas A temperate South American grassland, the largest continuous area being in the eastern Argentinian province of Buenos Aires, together with parts of the adjacent provinces. Much of the moister sector of the pampas is now cultivated, but formerly it was covered by bunch grasses, in between the individual tussocks of which the soil lay bare. To the west and south-west drier conditions prevail, and here the pampas comprises a mixture of short grasses and xerophytic shrubs.
