WeForest and AES Brasil are collaborating to restore the forest on the edges of the Tietê river in the Atlantic Biome and its tributaries with native species, protecting water bodies from soil siltation and runoff from herbicides and pesticides.

The project is also providing a testing ground for restoration approaches that aim to reduce the use of herbicides – which are usually relied on in Brazil to control invasive grasses – or eliminate them entirely.

Why and how we’re working here

Alongside the Tietê river, one of the most polluted rivers in Brazil, significant deforestation has taken place.
Most of the remaining forest patches are small and isolated, and many plant and animal species are threatened with extinction.

The project’s impact on people and nature

As well as restoring riparian forests and establishing wildlife corridors, the project protects water resources and improves the water supply, transitioning the region away from the use of herbicides that can have long-term damaging effects on biodiversity, water bodies and humans.
