Abstract. Sustained poaching over the past decade has led to significant loss of black (Diceros bicornis) and southern white (Ceratotherium simum simum) rhinoceroses across South Africa. Whereas much research has focussed on the heavily targeted state-owned populations, there is little understanding of the trends and challenges faced by rhino populations held in the private sector. Private rhino ownership has increased substantially across South Africa over the past three decades, with over 42% of the entire rhino population now in private ownership. Although total rhino numbers on private properties are still increasing, the number of properties owning rhinos is declining. This suggests a move away from traditional extensive properties to large, single-species breeding facilities, which are less valuable from a conservation perspective. The economic impact associated with increased poaching of rhinos over the past decade is the major challenge to private rhino ownership and may encourage disinvestment in rhinos. Some private rhino owners advocate for trade in rhino horn to generate the funds necessary for continued protection of their animals. However, other options to reduce disinvestment, such as local community-engagement projects, are likely to be more favourably received by the wider conservation industry.

南非私人犀牛所有权的未来

摘要。过去十年持续的偷猎导致南非境内的黑犀牛（Diceros bicornis）和南部白犀牛（Ceratotherium simum simum）大量减少。尽管许多研究都集中在重点关注的国有人口上，但对私营部门持有的犀牛种群所面临的趋势和挑战却知之甚少。在过去的 30 年里，南非的私人犀牛所有权大幅增加，现在整个犀牛种群的 42% 以上为私人所有。尽管私人财产上的犀牛总数仍在增加，但拥有犀牛的财产数量却在下降。这表明要从传统的粗放财产转移到大型单一物种繁殖设施，从保护的角度来看，这些设施的价值较低。过去十年间犀牛偷猎增加带来的经济影响是对私人犀牛所有权的主要挑战，并可能鼓励对犀牛的投资减少。一些私人犀牛主人提倡犀牛角贸易，以筹集持续保护他们的动物所需的资金。然而，其他减少撤资的选择，例如当地社区参与项目，可能更受更广泛的保护行业的欢迎。
