The Eastern Arc Mountains are a global biodiversity hot spot, and this biodiversity must be maintained. Tree nursery projects to reforest lands in the Usambara Mountains African Rainforest are an excellent way to achieve this imperative. Population growth puts further pressure on the Forest Nature Reserve as people need building materials, cooking fuel, and other tree products. The project has the objective to enhance tree planting in and around villages adjacent to Nature Forest Reserve and the Jegestal water source. By assuring adequate tree availability to communities in the Usambara Mountains, we can avoid the unsustainable illegal use of the Reserves.
