This study investigates illegal border crossings by rhino poachers into a fenced reserve in South Africa, comparing journeys to and after crime using a rational choice approach. Using various regression models, our analysis indicates poachers prefer to enter and exit the reserve near high rhino densities, while high road densities outside the reserve increase the odds of an illegal entry. The results also show that half of the incursions occurred at a single location, leading us to describe the special circumstances of this outlier. The study lays a foundation for understanding the location choices poachers make and presents a methodology that can be replicated in other reserves.

了解非法越境进入围栏​​保护区的地点选择：一种合理的选择方法

这项研究调查了犀牛偷猎者非法进入南非有围栏的保护区的过境行为，并使用理性选择方法比较了犯罪前后的旅程。使用各种回归模型，我们的分析表明，偷猎者更喜欢在高犀牛密度附近进入和离开保护区，而在保护区之外的高道路密度会增加非法进入的可能性。结果还表明，一半的入侵发生在单个位置，这使我们描述了这种异常情况的特殊情况。该研究为了解偷猎者做出的位置选择奠定了基础，并提出了可以在其他保护区中复制的方法。
