When Brazilian photographer Sebastião Salgado returned to his family’s land in Brazil during the 1990s, he found a devastated landscape instead of the green jungle he remembered from childhood.
Years of deforestation, livestock grazing, and soil degradation have stripped the land of wildlife, water, and greenery. The rivers dried up and much of the ecosystem seemed on the verge of collapse. But instead of abandoning the land, Salgado and his wife, Lilia Wanik Salgado, began one of the world’s most notable reforestation efforts. Over the next two decades, the couple helped plant more than two million trees and transform the barren region into a thriving tropical forest once again.
How a couple planted two million trees to bring back the forest
The project began after Sebastião Salgado returned to his homeland after years spent documenting wars, famine and humanitarian crises around the world through photography. According to interviews, the emotional impact of witnessing global suffering left him extremely exhausted.When he returned to his family farm in the Brazilian state of Minas Gerais, he expected to reconnect with the rich Atlantic forest ecosystem that once covered the region.
Instead, most of the land has become dry, degraded, and virtually devoid of life.It was Lilia Wanick Salgado who proposed the idea of completely restoring the forest. Although the task seemed impossible at first, the couple decided to start a long-term ecological recovery project focusing on local ecosystems rather than commercial forests.In 1998, the couple founded the Terra Institute, a non-profit organization dedicated to environmental restoration, environmental education, and sustainable land recovery.The organization began collecting local seeds, building nurseries, and researching how to restore the damaged Atlantic Forest biome. Instead of planting fast-growing commercial species, the project focused on restoring the area’s natural biodiversity.Scientists and environmentalists involved in the project carefully selected native tree species capable of rebuilding soil quality, restoring water systems and supporting wildlife habitat.Over the course of nearly 20 years, the Terra Institute has helped plant more than two million native trees across hundreds of hectares of degraded land.The restoration included a wide range of species originally found in Brazil’s Atlantic Forest ecosystem. This diversity was important because forests depend on complex ecological interactions between plants, insects, birds, fungi, and animals.As the trees matured, the environment gradually began to repair itself.
The roots stabilized the soil, the leaf mulch lowered surface temperatures and significantly improved water retention.Over time, the once barren landscape slowly transformed back into a functioning tropical forest ecosystem.
Wildlife and rivers have returned to the area
One of the most prominent results of the project is the return of wildlife. As the vegetation has recovered, many animal species have reportedly reappeared in the area after years of absence.Environmental reports associated with the project have documented the return of birds, mammals, reptiles and insects with increased biodiversity across the restored forest.The renovation also improved local water systems. Springs and streams that had weakened or dried up reportedly began flowing again as the forest regained its ability to retain moisture and regulate the microclimate.Healthy forests play a key role in maintaining rainfall patterns, groundwater systems and temperature balance, researchers say.
Why is the Atlantic Forest globally important?
The Atlantic Forest, also known as Mata Atlantica, is one of the most biodiverse ecosystems in the world.
It once extended across large parts of the Brazilian coast and inland areas.However, centuries of logging, agriculture, mining, and urbanization have destroyed most of the original forest cover. Scientists estimate that only a small portion of the Atlantic Forest remains alive today.Despite the devastation, the area is still home to thousands of plant species and many rare animals found nowhere else on Earth.
For this reason, restoration projects such as the Terra Institute are of international importance for environmental conservation and resilience to climate change.
Sebastião Salgado went from photographer to environmental activist
Before starting the reforestation project, Sebastião Salgado was internationally known for his black and white documentary photography.He is best known for documenting migration, labor, famine, war, and indigenous communities across multiple continents.
His work often focused on human suffering and social inequality.Many observers believe the restoration project has become an environmental mission and a personal healing journey for Salgado after decades spent photographing global crises.The restoration of the forest later influenced his “Genesis” photography project, which focused on pristine landscapes, wildlife and traditional cultures around the world.
The science behind forest restoration
Environmental restoration involves much more than planting trees. Forest ecosystems depend on interactions between soil organisms, fungi, insects, water systems, and wildlife.When native species are carefully reintroduced, forests can gradually regain many of their natural processes. Trees improve soil fertility, create shade, store carbon dioxide, and provide habitat for animals that help spread seeds and maintain biodiversity.Over time, these ecological relationships help create a self-sustaining cycle of renewal.Scientists increasingly view reforestation and ecosystem restoration as important tools to address climate change, biodiversity loss, and water insecurity.
Why has the story inspired people around the world?
The story of Sebastião and Lilia Salgado gained international attention because they showed that even severely damaged ecosystems can recover through long-term restoration efforts.Many people were not only inspired by the scale of the project, but also by the patience involved in the project. The transformation took decades, not months, requiring sustained work, environmental planning, and commitment.The project also challenged the belief that environmental destruction is always irreversible. Instead, it has become a powerful example of how biodiversity and natural systems can recover when given enough protection and time.
A lasting environmental legacy
Today, the Terra Institute continues its restoration and environmental education work in Brazil. The organization trains students, supports conservation projects, and promotes sustainable land management practices.The forest that the Salgados regrown is now one of the world’s most famous examples of people-led ecological restoration.Their work has become a symbol of environmental resilience and demonstrated that restoring nature is possible even after decades of devastation.
