Establishing reintroduced primates in a suitable predetermined area has proven to be a challenge. Establishment is the first major step that has to be taken in the long process of reintroduction. When this first goal is not achieved, the chances of success decline drastically. Understanding the main determinants of establishment is therefore crucial for reintroduction success. This study examined the influence of three independent factors on the establishment success of reintroduced spider monkeys. We analysed data from the releases of eight groups of black-faced spider monkeys (Ateles chamek), which are part of the official reintroduction program of spider monkeys in the South Eastern Peruvian Amazon. Establishment success was measured by the proportion of individuals within groups that were found in the target area 6 months after release. The hours research assistants and volunteers spent with the group within the first 3 months after release-in the context of post-release monitoring-was shown to have a positive effect on the establishment success of the released group in the target area. The presence of an already established group in the area was also found to have a significant positive effect on establishment success. The influence of the days of post-release food provisioning had no effect. Our findings emphasize the importance of long-term monitoring programs to help increase the efficiency of primate reintroductions.
在合适的预定区域建立重新引入的灵长类动物已被证明是一项挑战。建立是重新引入这一漫长过程中必须采取的第一个主要步骤。如果这第一个目标没有实现，成功的机会就会大大减少。因此，了解建立的主要决定因素对于重新引入的成功至关重要。本研究探讨了三个独立因素对重新引入的蜘蛛猴建立成功的影响。我们分析了来自八个黑脸蜘蛛猴（Ateles chamek）群体释放的数据，这些群体是秘鲁东南部亚马逊地区官方蜘蛛猴重新引入计划的一部分。建立成功的衡量标准是，在释放后 6 个月内，群体中在目标区域内发现的个体比例。研究助理和志愿者在释放后 3 个月内与群体一起度过的时间（在释放后监测的背景下），对释放群体在目标区域的建立成功有积极影响。在该地区已经存在一个已建立的群体也被发现对建立成功有显著的积极影响。而释放后食物供应的天数没有影响。我们的研究结果强调了长期监测计划的重要性，以帮助提高灵长类动物重新引入的效率。
