A Kenyan Wildlife Service (KWS) ranger stands guard on a tree stump during a tree planting session at the Kaptunga station of the Mau Forest complex in the Kenyan Rift Valley, January 15, 2010. Kenya's coalition government launched a tree planting exercise after relocating about 20,000 families from the Mau forest, the country's biggest closed-canopy forest and a vital water catchment area.
