%X The study presents recent measurements (1988)of deforestation obtained from Landsat - TM imagery for the whole Legal Amazonia (4 906 784.4 Sq. Km). Focus is given on forest depletion rates for the Legal Amazonia based on the analysisi of deforestation rates available in the last thirteen years. Deforestation measurements are contrasted with mathematical deforestation projection published elsewhere wich mainly assume axponetial rates of forest depletion. The study shows that up to the year of 1988, 251 429.55 Sq. Km of the Legal Amazonia have been deforested, this is equivalent to 5.12 of the area of the Legal Amazonia and does not include very old deforestation values for the Para and Maranhao State. If one assumes a linear deforestation growth and uses the highest deforestation rates observed in the last thirteen years in the Legal Amazonia one should expect a projected value of 272 858.16 Sq.Km by the end of 1989.
