This study aimed to examine livestock-wildlife interactions at the micro level and to quantify how resources are shared in joint land use by comparing the monitoring records collected on the Lolldaiga Hills ranch in Laikipia, Kenya from 1990s onwards. Livestock and wildlife distributions together with existing water points were geo-referenced; by air and road census total animal biomass densities were estimated. Through 38-h observation at a water point, livestock-wildlife interaction was recorded. During this period, water decline has been identified as an acute factor for farming and ranching. It was found that distributions of livestock and wildlife were related to water and pasture availability during the severe drought in 2009. Although there is seasonality in densities of both livestock and wildlife populations, results of air census indicated that the stable resident populations of wildlife have resided on the ranch. In this paper, we describe how livestock and wildlife interact at a water point and on pastures on the ranch in terms of biomass density. Such resources shared at different times need to be investigated further as a key factor to improve productivity of livestock-wildlife joint land use.
