Human activities during the last decades provoked a notable reduction in global forest cover. Knowing that <br/> forest stands act as stock and sinks for carbon and other greenhouse gases, it is important to determine the existing forest <br/> cover at country level and to calculate annual deforestation rates. This work uses NOAA satellite images in a resolution of <br/> 1 km x 1 km to classify the surface of continental Ecuador in “forest” – “non-forest” pixels and to estimate the annual <br/> deforestation rate from 1986 to 2001 as well as from 2001 to 2008. The method is based on a decision tree algorithm that <br/> includes different spectral bands of the NOAA-AVHRR sensor and additional topographic and meteorological parameters. <br/> The results show that the total forest cover of continental Ecuador was reduced from 48.1 % in 1986 to 36.8 % in 2008. The <br/> calculated annual deforestation rates indicate that forest reduction increased during the last decade. The most affected area <br/> is the Coastal Lowland, due to the enhanced population pressure, followed by the Amazon Basin, not only caused by the <br/> governmental supported oil and mining industry, but also due to the uncontrolled timber extraction. The Andean Highland <br/> has been less affected, because the major parts of this region were deforested before, during the Pre-Columbian-Era.
