The Udumuka Reforestation Project is Green Horizon’s pilot initiative in Tanzania, designed to restore degraded landscapes, rebuild biodiversity, and support local communities. By planting native trees and integrating ecological principles, Udumuka serves as a foundation for future large-scale restoration efforts across the region.
Why Udumuka?
Tanzania’s dry miombo woodlands are among the most biodiverse ecosystems in East and Southern Africa, yet they are increasingly under threat due to deforestation and land degradation. Iringa, where the Udumuka project is based, has lost significant tree cover due to unsustainable land use practices.
Green Horizon aims to restore these critical landscapes using ecological design principles that mimic the natural dynamics of the miombo woodland ecosystem while adapting them to fit the project’s specific goals and constraints.
By selecting native tree species and restoring degraded land, this project not only captures carbon but also re-establishes natural processes, ensuring long-term resilience for the local environment and its people.
Our approach
Our work in Udumuka is guided by:
Ecological Restoration
The project is designed to replicate the natural regeneration of dry miombo woodlands, ensuring the right tree species are selected for long-term resilience.
Community Involvement
We work closely with local farmers and conservation experts, creating employment opportunities in nurseries and tree-planting.
Scientific Monitoring & Transparency
We partner with OpenForestProtocol (OFP) to provide tamper-proof, on-chain data verification, ensuring high-integrity impact tracking and nature based credits.



Community Impact
At Green Horizon, we believe that restoration should benefit both nature and people.
Udumuka has provided:
Employment opportunities
Local community members have been engaged in tree nurseries, planting activities, and long-term site maintenance.
Conservation awareness
The project raises awareness about the importance of miombo woodlands, ensuring that local communities are actively involved in protecting reforested areas.
By restoring the landscape while integrating community participation, we ensure that the benefits of this project extend beyond the environment—strengthening livelihoods, improving soil health, and protecting water sources.
What's Next?
The Udumuka Project is just the beginning. Green Horizon is preparing for larger reforestation and restoration efforts across Tanzania.
Future projects include:
Njombe Reforestation (5,000 hectares)
A large-scale forest restoration project planned for 2025.
Iringa Landscape Restoration (150,000 hectares)
A long-term initiative focused on rewilding degraded lands and restoring ecosystem functions in collaboration with local villages.
