Planting of native species in the Permanent Preservation Area
As a compensatory measure for the formation of the reservoirs, it was established that the surroundings of the flooded stretches would form a continuous Permanent Preservation Area (APP) strip of variable width, with an average of 500 meters. This comes together to form an area measuring approximately 26,000 hectares, which corresponds to about twice the area of vegetation suppression for the deployment of the reservoirs.
Since 1970, this area surrounding the reservoirs has undergone deforestation due to occupation by rural settlements, resulting in the suppression of 60% of the region's native forests. As the reforestation process will involve native species changes from the region itself, the area that is now very fragmented will be restored, with the maintenance and recovery of the original biodiversity.
