Unsustainable snaring is causing biodiversity declines across tropical protected areas, resulting in species extinctions and jeopardizing the health of forest ecosystems. Here, we used 11 years of ranger-collected data to assess the impact of intensive snare removal on snaring levels in two protected areas in Viet Nam. Snare removal resulted in significant declines in snare occupancy (36.9, 95% Bayesian credible interval [4.6, 59.0] reduction in percent area occupied), but snaring levels nonetheless remained high (31.4, [23.6, 40.8] percent area occupied), and came with a substantial financial cost. Our results indicate that snare removal remains an important component of efforts to protect tropical protected areas but by itself is likely insufficient to address this threat. To stop snaring in protected areas, a multifaceted approach will be necessary that combines short-term reactive snare removal with long-term proactive programs that address the underlying drivers behind snaring.

解决东南亚的圈套危机：生物多样性热点地区 11 年来拆除圈套的影响


不可持续的诱捕正在导致整个热带保护区的生物多样性下降，导致物种灭绝并危及森林生态系统的健康。在这里，我们使用护林员 11 年收集的数据来评估密集清除圈套对越南两个保护区的圈套水平的影响。圈套去除导致圈套占用率显着下降（36.9，95% 贝叶斯可信区间 [4.6, 59.0] 占用面积百分比减少），但圈套水平仍然很高（31.4，[23.6, 40.8] 占用面积百分比），并且并付出巨大的财务成本。我们的研究结果表明，清除圈套仍然是保护热带保护区工作的重要组成部分，但其本身可能不足以应对这一威胁。为了阻止保护区内的诱捕，需要采取多方面的方法，将短期反应性诱捕消除与解决诱捕背后潜在驱动因素的长期主动计划结合起来。
