However rapid change arising from multiple factors including landscape fragmentation sedentarization and demographic drivers might affect the effectiveness of this pastoral coping strategy in times of drought. We investigate livestock mortality rates following the 2005 drought in four areas in Maasailand the Maasai Mara the Kitengela plains the Amboseli and the Simanjiro plains. The main aim was to assess the mortality of resident livestock in relation to incoming livestock during the drought. Contrary to our expectations livestock mortality rates were significantly higher 43 in Kitengela which experienced above-average rainfall compared to the other three areas which had below-average rainfall yet experienced mortality rates between 14 and 30 . Two processes might explain this surprisingly high mortality rate. Firstly the immigration of large numbers of livestock from drought-stricken areas into the highly fragmented Kitengela area increased stocking density which worsened the shortage of forage and water. Secondly the more market-oriented but less drought-resistant livestock breeds in Kitengela form another explanation for the increased mortality. These observations suggest that pastoral mobility may lead to greater .
