above sea level, in areas partially covered with secondary Atlantic forest. The impact of human activities is visible along the entire course of rio Macabu. On the mountain slopes the main visible impacts are the presence of several buildings on the river banks, and also the deforestation for several purposes, such as agriculture and cattle raising.
