Healing & spiritual Mining site (Landsat ETM+ false colour composite). The artificial lakes are dark blue, mangrove wetlands dark green, bare ground pink and white Schools Description Mobimbi Isolated patch of tall forest. Very hilly and rocky area close to SRL HQ, threat of farming on the other side. Top soil enriched by presence foliage and litter Lanti South 3. Experimental Restoration Very poor growing conditions on the sand tailings following mining (~0.07% C and ~0.003% N). The project encouraged a decentralised business reclamation initiative - compost and seedling production in local villages Mixture of farmland and secondary forest regrowth with some swamp. Top soil enriched by presence foliage and litter. Lanti Incomplete reclamation of a canal constructed to move the dredge.
