Conteúdo: 	We have developed a map of the land cover of South America based largely on NOAA AVHRR LAC (Local Area Coverage) 1-km resolution data. Areas of South America for which there were no LAC data due to cloud cover or other reasons were supplemented with a 3-year time series of 15-km resolution NOAA AVHRR GVI data. Thirty-nine classes were labeled using existing vegetation maps, from phenology, and by visual interpretation of imagery. We estimated that nine percent of the closed tropical moist forests of South America had been cleared in the decade prior to 1988, the date of the imagery; 22 percent of the original closed forests, which include tropical moistforests as a major component, of South America had been cleared or degraded; 18 percent of the original woodland and 25 percent of the grassland had been cleared or degraded
