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.

The region supports more than 100 mammal species, including the puma (Puma concolor) and the maned wolf (Chrysocyon brachyurus), of which 6 are threatened. © WeForest
It’s also home to over 400 bird species, of which 18 are threatened, more than 40 amphibian species, and several endangered or vulnerable tree species. © Bruno Francisco
In Brazil, invasive grasses and leaf-cutter ants are two major obstacles to forest restoration, and they are usually controlled with herbicides and insecticides. While it is possible to control them with a fully organic approach, it is extremely laborious and difficult to do on a large scale. © WeForest
The project serves as the perfect opportunity to experiment with ways to reduce or eliminate the use of herbicides and pesticides by testing different spatial arrangements or species combinations, and developing best practices. © WeForest
