ABSTRACT The woody vegetation in arid and semi-arid area is of immense importance performing a myriad of ecosystem services and providing a wide array of goods. However, the woody vegetation is threatened by both natural and anthropogenic activities at global, national and local levels. In Kerio Valley, the threat is manifested in the form of overexploitation for fuel wood and land-use change due to mining activities. This study aimed to assess the effects of mining activities on the composit...
