Abstract

In the southern Bago Yoma mountain range in Myanmar, Asian elephants are being killed at a disturbing rate. This emerging crisis was identified initially through a telemetry study when 7 of 19 of collared elephants were poached within a year of being fitted with a satellite-GPS collar. Subsequent follow up of ground teams confirmed the human caused death or disappearance of at least 19 elephants, including the seven collared individuals, within a 35 km2 area in less than two years. The carcasses of 40 additional elephants were found in areas located across south-central Myanmar once systematic surveys began by our team and collaborators. In addition to the extreme rate of loss, this study documents the targeting of elephants for their skin instead of the more common ivory, an increasing trend in Myanmar. Intensive research programs focused on other conservation problems identified this issue and are now encouraging local authorities to prioritize anti-poaching efforts and improve conservation policies within the country. Myanmar represents one of the last remaining countries in Asia with substantial wildlands suitable for elephants. Increasing rates of human-elephant conflict and poaching events in this country pose a dire threat to the global population.

摘要

在缅甸南部的巴山玉山脉,亚洲象正以惊人的速度被杀害。这一新兴危机最初是通过遥测研究发现的,在 19 头佩戴卫星 GPS 项圈的大象中,有 7 头在佩戴后的一年内被偷猎。随后,地面团队的后续跟进确认,在不到两年的时间里,至少有 19 头大象在 35 平方公里的范围内因人为原因死亡或失踪,其中包括 7 头佩戴项圈的大象。在我们的团队和合作伙伴开始进行系统调查后,在缅甸中南部的其他地区还发现了另外 40 头大象的尸体。除了极高的死亡率外,本研究还记录了大象的皮肤被偷猎,而不是更常见的象牙,这是缅甸日益增长的趋势。专注于其他保护问题的密集研究计划发现了这一问题,现在正在鼓励当地当局优先考虑打击偷猎活动,并改善该国的保护政策。缅甸是亚洲最后几个拥有大片适合大象生存的野生地区的国家之一。该国不断增加的人与象冲突和偷猎事件对全球大象种群构成了严重威胁。
