dc.description.abstractThere is growing evidence of escalating wildlife losses worldwide Extreme wildlife losses have recently been documented for large parts of Africa including western Central and Eastern Africa Here we report extreme declines in wildlife and contemporaneous increase in livestock numbers in Kenya rangelands between 1977 and 2016 Our analysis uses systematic aerial monitoring survey data collected in rangelands that collectively cover 88 of Kenyas land surface Our results show that wildlife numbers declined on average by 68 between 1977 and 2016 The magnitude of decline varied among species but was most extreme 7288 and now severely threatens the population viability and persistence of warthog lesser kudu Thomsons gazelle eland oryx topi hartebeest impala Grevys zebra and waterbuck in Kenyas rangelands The declines were widespread and occurred in most of the 21 rangeland counties Likewise to wildlife cattle numbers decreased 252 but numbers of sheep and goats 763 camels 131 and donkeys 67 evidently increased in the same period As a result livestock biomass was 81 times greater than that of wildlife in 20112013 compared to 35 times in 19771980 Most of Kenyas wildlife ca 30 occurred in Narok County alone The proportion of the total ªnationalº wildlife population found in each county increased between 1977 and 2016 substantially only in Taita Taveta and Laikipia but marginally in Garissa and Wajir counties largely reflecting greater wildlife losses elsewhere The declines raise very grave concerns about the future of wildlife the effectiveness of wildlife conservation policies strategies and practices in Kenya Causes of the wildlife declines include exponential human population growth increasing livestock numbers declining rainfall and a striking rise in temperatures but the fundamental cause seems to be policy institutional and market failures Accordingly we thoroughly evaluate wildlife conservation policy in Kenya We suggest policy institutional and management interventions likely to succeed in reducing the declines and restoring rangeland health most notably through strengthening and investing in community and private wildlife conservancies in the rangelandsen_US
