A family in Brazil has planted 840,000 native trees and restored over 600 hectares of Atlantic Forest, and their efforts have brought back a species not seen in 103 years. The project, led by Nicholas and Raquel Locke, began in the 1990s on degraded land in Cachoeiras de Macacu, Rio de Janeiro state, and has since become a global model for reforestation.
From Degraded Pasture to Thriving Forest
When Nicholas and Raquel Locke received the land, it had been punished for decades by cattle ranching and deforestation. The area was part of the Mata Atlântica, one of Brazil's most threatened ecosystems, which had been reduced to isolated fragments.
Instead of continuing to exploit the land, the couple decided to reverse the damage. In 2001, they consolidated the Guapiaçu Ecological Reserve (REGUA) with a simple but ambitious goal: protect what remained and bring trees back to everything that could recover.

The restoration was done gradually, using native species from the Atlantic Forest. REGUA established a nursery that worked with around 120 native species, many grown from seeds collected in nearby forests. Conservation organizations like World Land Trust provided support.

How Reforestation Brought Back a Lost Species
The result is not measured only in trees. The return of a creature unseen for 103 years shows how large-scale restoration can revive biodiversity. While the source article does not specify which species returned, the fact that it reappeared after more than a century highlights the ecological value of connected habitats.
Reforestation creates corridors that allow wildlife to move, feed, and breed. As the forest regrew, it provided shelter and resources for animals that had disappeared from the region. This is a powerful example of how human intervention can help ecosystems recover.
Key Takeaways from the REGUA Project
- Over 840,000 native trees planted since the 1990s.
- More than 600 hectares of Atlantic Forest restored.
- Around 120 native species used in reforestation.
- A species not seen for 103 years has returned to the area.
- The project shows that large-scale restoration is possible with dedication and community support.
The Importance of the Atlantic Forest
The Atlantic Forest is one of the most biodiverse ecosystems on Earth, but it has been heavily deforested for agriculture, ranching, and urban development. Today, only a fraction of its original cover remains, mostly in small fragments.
Restoring the Atlantic Forest is crucial for carbon sequestration, water regulation, and habitat connectivity. REGUA's work demonstrates that even severely degraded land can be brought back to life with the right approach.
The project also supports local communities through education and sustainable livelihoods, showing that conservation and human well-being can go hand in hand.
Challenges and Lessons Learned
Reforestation is not without challenges. It requires long-term commitment, funding, and scientific knowledge. REGUA faced issues such as invasive species, soil degradation, and the need to engage local stakeholders.
One key lesson is the importance of using native species and local seed sources to ensure genetic diversity and resilience. Another is the need for adaptive management: monitoring progress and adjusting strategies as the forest evolves.
The project's success has inspired other restoration initiatives in Brazil and beyond, proving that large-scale ecological restoration is achievable. Context on how this played out before sits in Brazil Family Plants 840,000 Trees, Brings Back Species After 103 Years.
What This Means for Global Conservation
The REGUA story is a beacon of hope amid global biodiversity loss. It shows that with vision, persistence, and collaboration, we can reverse some of the damage done to our planet. The background to this story is set out in Ethiopia Reforestation: 50 Billion Trees and Climate Action. A related thread runs through Spanish Engineer Reforested 5,000 Hectares by Shooting Seeds.
As the world faces climate change and ecosystem collapse, such projects offer a roadmap for restoring degraded landscapes and bringing back lost species. They also highlight the role of private individuals and local communities in conservation. Earlier coverage in Energy Utilities: latest articles shows how the argument developed. A closer look at the same subject appears in Can Countries Deliver on the Global Biodiversity Deal.
Governments and organizations can learn from REGUA's model and scale up similar efforts to meet global restoration targets like the Bonn Challenge and the UN Decade on Ecosystem Restoration.
