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.
本研究旨在从微观层面研究牲畜-野生动物的相互作用，并通过比较肯尼亚莱基皮亚的洛利达加丘陵牧场从 20 世纪 90 年代以来收集的监测记录，来量化在联合土地利用中资源是如何共享的。牲畜和野生动物的分布情况以及现有的水源点都进行了地理参考定位；通过空中和道路普查，估计了动物生物量密度的总数。在一个水源点进行了 38 小时的观察，记录了牲畜-野生动物的相互作用。在此期间，已经确定水位下降是农业和牧场经营的一个严重问题。研究发现，在 2009 年严重干旱期间，牲畜和野生动物的分布与水和牧草的供应有关。尽管牲畜和野生动物的密度都存在季节性，但空气普查的结果表明，稳定的野生动物常驻种群一直生活在牧场上。在本文中，我们根据生物量密度描述了在牧场的一个水源点和牧场上牲畜和野生动物是如何相互作用的。需要进一步研究这些在不同时间共享的资源，因为这是提高牲畜-野生动物联合土地利用生产力的关键因素。
