UK Charity Excellent supports communities in rural semi-arid regions of Africa to regenerate degraded environments and create sustainable livelihoods. In rural Africa 80% of people rely on traditional medicines for primary health care. However unsustainable exploitation threatens many of the indigenous medicinal trees from which these traditional medicines are harvested. In Kenya, Excellent's TreeDuty forests protect these rare, often difficult to grow species in a secure fenced and watered environment. The rainwater harvesting methods used as well as the trees themselves help conserve soil and water and restore degraded and deforested environments.
