Local and regional extirpations of individual species, typically high profile cases, are now well documented, leading to calls for urgent action for particular species in specific locations. There is a need to broaden our assessments of extinction to identify landscapes that contain high proportions of threatened species and therefore, how more holistic species conservation responses might be developed. The conservation status of species is especially concerning in Southeast Asia and within the region, the avian family Phasianidae affords the opportunity to develop an approach for examining species richness and extinction probability for an entire family at landscape scale. There are 42 pheasant, partridge and quail species in the region and 77% of Southeast Asia encompasses the geographic range of at least five species. Due to high levels of uncertainty about how species respond to anthropogenic threats, we created an expert elicited Bayesian Belief Network to explore survival prospects using publically available data on IUCN extinction probability categories, proxies of threat (effects of hunting, forest loss and protected area effectiveness) and species geographic ranges to assess where the overall risk to survival was highest.

东南亚雉科动物保护现状

局部和区域性的个别物种灭绝（通常是引人注目的案例）现已得到充分记录，导致人们呼吁对特定地点的特定物种采取紧急行动。有必要扩大我们对灭绝的评估，以确定含有高比例受威胁物种的景观，从而确定如何制定更全面的物种保护对策。物种的保护状况在东南亚和该地区尤其令人担忧，鸟类科雉科提供了开发一种在景观尺度上检查整个科的物种丰富度和灭绝概率的方法的机会。该地区有 42 种雉鸡、鹧鸪和鹌鹑，其中 77% 的东南亚地区包含至少 5 种的地理范围。由于物种如何应对人为威胁存在高度不确定性，我们创建了一个专家引发的贝叶斯信念网络，利用有关 IUCN 灭绝概率类别、威胁代理（狩猎、森林丧失和保护区有效性的影响）的公开数据来探索生存前景）和物种地理范围，以评估总体生存风险最高的地区。
