Poaching of wildlife presents one of the biggest conservation challenges in the 21st century. Snaring is one of the primary means of capturing target animals. To prioritise interventions intending to reduce snaring, we describe an approach for quantifying the configuration and lethality of snares. We conducted transect surveys in Murchison Falls National Park. All the snares that we recovered were made of wire with the majority (81.0%, n = 546 of 674) deriving from vehicle tire wire. The density of snares ranged from 0.08 to 4.58 snares/km2, which is the highest known density in sub‐Saharan Africa. The majority (63%) of the animals caught in wire snares were unrecovered and wasted. We found that noose width, vertical drop, wire circumference, anchor height, proportion of un‐thicketed area, grass height, distance to river and village had a significant positive relationships to lethality, while snare thickness, charms, tree DBH, thicket diameter, distance to nearest road negatively affected lethality. We recommend adopting wholistic anti‐snare countermeasures such as the human heritage‐centred conservation to empower local people. Our method illustrates the opportunity to standardise temporal and spatial measurements of snare density and configuration necessary to stop illegal wildlife poaching.

大型食肉动物和有蹄类动物同伴行会的小偷猎的景观构图和杀伤力

偷猎野生生物是21世纪最大的保护挑战之一。诱捕是捕获目标动物的主要手段之一。为了确定旨在减少缠扰的干预措施的优先级,我们描述了一种量化圈套器的配置和致死率的方法。我们在默奇森瀑布国家公园进行了横断面调查。我们回收的所有网罗都是由金属丝制成的,其中大部分(81.0%,n  = 546的546)来自于汽车轮胎的金属丝。圈套器的密度范围为0.08至4.58圈套器/ km 2,这是撒哈拉以南非洲地区已知的最高密度。被钢丝圈套器捕获的大多数动物(63%)没有被恢复和浪费。我们发现,套索宽度,垂直下落,导线周长,锚定高度,未开孔面积的比例,草高,与河流和村庄的距离与杀伤力呈显着正相关,而圈套厚度,护身符,树木DBH,灌丛直径,距最近道路的距离对杀伤力有负面影响。我们建议采取诸如以人类遗产为中心的保护之类的全面性反贪污对策,以增强当地人民的能力。我们的方法说明了机会,可以使抑制非法野生生物偷猎所必需的圈套密度和配置的时间和空间测量标准化。
