Hydro replants forested areas disturbed by mining, and the study by the Brazil-Norway Biodiversity Research Consortium (BRC) brings encouraging results about the presence of birds in reforested areas in the region.

The research, “Diversity of birds in three areas in different states of conservation,” started in 2017, found the return of birds in areas under recovery in Paragominas, where Hydro's bauxite mine is located. So far, 228 species have been found during the research.

The objective of environmental recovery is to re-establish the elements of the ecosystem. After eight years of reforestation, species of birds that feed on seeds, fruits or plant parts were found. Another important indicator is the fact that all species found reproduce at the site.

In the forest areas of Hydro Paragominas, some birds threatened with extinction, such as the “Ararajuba,” or Golden parakeet, have also been found. An excellent indicator of the quality of the remaining forests in the Hydro area is the presence of the “Gavião Real,” or Harpy eagle, which is at the top of the food chain and has already been found in the native forest area near the mine. This indicates that the remaining forests in the area are in a good state of conservation and will be essential for the area's forest recovery process as a source of colonization of bird species.

“We were happy to see that the reforestation work carried out at Hydro Paragominas is on the right track. The Amazon is a complex and unique environment on the planet. It requires greater attention to fully recover and, to help us understand all this complexity, we are counting on the BRC,” says Domingos Campos, Sustainability Director at Hydro in Brazil.

Professor Marcos Persio, who is leading the bird research project, says “Hydro's work has gone beyond simple reforestation. The investment in research allows us to know if the method being used in each location is enabling the mined area to be recovered and the animals that lived in the past to be able to return. That's where the BRC comes in. We don't see this in any other company in the region.”

The next step in the work carried out by the BRC team is monitoring the birds using collars to study their habits and movements. Currently, 10 researchers are working on the bird study.
