20 165 503Trees planted

Alongside the Friends of Usambara Society, a Tanzanian NGO, Reforest'Action is financing the planting of 500,000 trees in the Magamba Nature Reserve in northeastern Tanzania.



Launch date: 2019

Main species planted: ficus, mahogany cedar, silky oak, African tulip tree, apple tree, peach, avocado, pear tree, plum tree, moringa, macadamia...

Objectives: Restore the biodiversity of the Usambara Mountains, raise awareness among local populations of the importance of forests

Associated partner: Friends of Usambara Society




The context

Between 1990 and 2010, Tanzania lost 19.4% of its forest area, or about 8 million hectares of forest. Today, the country is still one of the most deforested in the world, with 400,000 hectares of forest destroyed each year. These include the expansion of agricultural land and pastureland at the expense of forests, cuts related to charcoal and firewood production, and forest fires due to industrial activities.

Our action and our partner in the field

A partnership between Reforest'Action and the Society of Friends of Usambara

Reforest'Action is associated with the Société des Amis d'Usambara, a Tanzanian NGO whose objective is to preserve the very rich animal and plant biodiversity of the Usambara Mountains, by planting trees and conserving the water sources of the Magamba, Yoghoi-Irente and Jegestal nature reserves. Reforest'Action is financing the planting of 1 million trees for the 2019-2020 season, out of a total target of 15 million trees targeted by the NGO. The trees will take root in the Magamba Nature Reserve in the northeast of the country, near the Kenyan border. The objective of this project? Restore the biodiversity of the Usambara Mountains, raise awareness among local populations of the importance of forests and agroforestry, and support them in the sustainable management of their trees.

Local populations involved in the project

Through this reforestation project, 204 villages and their inhabitants are mobilized to set up nurseries for young shoots during the dry seasons (January-February and September-October) and to plant trees the rest of the year. Micro-nurseries are also located in 6 schools and participate in the school program of forest protection education received by the schoolchildren associated with the project. They thus serve as true science laboratories for students, who are introduced to environmental protection, botany and horticulture, and apply their courses by participating in work in nurseries. After planting, the trees are monitored by experts from the Friends of Usambara Society to ensure that they grow well.

The species planted on the project

More than ten species are planted on the project:

  • Ficus, Cedreala odorata, Grevillea robusta and Spathodea campanulata, top-jet species that will be planted in the heart of the existing forests of the Magamba Nature Reserve to restore their soil, cover and biodiversity;
  • Apple, peach, avocado, pear, plum, moringa and macadamia, fruit species that will be planted in agroforestry, on farmers' plots, in order to protect the underlying crops and provide local populations with additional income from the sale of their fruits and seeds;
  • Albizia Shimperiana and Croton Megalacapus, fast-growing species, which will provide communities with a sustainably managed wood resource to avoid cutting within existing forests.

The benefits of the project

  • Biodiversity restoration in the Usambara Mountains, one of the world's biodiversity hotspots
  • Preservation of the Lushoto Jegestal watershed, which supplies more than 20,000 people with water in the Usambara Mountains and the city of Lushoto
  • Creation of additional income for local populations through the sale of fruits and seeds from trees planted in agroforestry
  • Raising local populations' awareness of sustainable development and forest protection through the involvement of schoolchildren in the reforestation programme
