The Amazon Forest Reserve Zone was created through the Law 2 of 1959, comprising the following general limits: starting from Santa Rosa de Sucumbíos, on the border with Ecuador, heading Northeast, up to the highest peak of the Picos de la Fragua; from there, following a line, 20 kilometers to the west of the Cordillera Oriental to the Alto de Las Oseras, from there in a straight line, for its shortest distance, to the Ariari River, and along the latter to its confluence with the Guayabero River or the Guaviare, which continues downstream to its mouth in the Orinoco; then you follow the border with Venezuela and Brazil, until you find the Amazon River, following the southern border of the country, to the starting point.
