The Eastern region comprises all of the national watershed systems along with the mountain ranges of Amambay, Mbaracayu, and Caaguazu, including Cerro San Rafael, Paraguay's highest peak at 2,788 feet. The region between the Paraguay and the Parana Rivers was once coveredwith rain forests. However, with the expansion of lumbering and farming activities, the forests are rapidly receding. At current rates of deforestation, virtually all of eastern Paraguay is expected to be stripped of its forestry cover by the year 2005.
