摘要:

监测保护地鸟兽多样性现状对区域内生物多样性保护具有重要意义。我们于2018年5月至2019年6月利用红外相机技术和公里网格方案在四川米亚罗省级自然保护区布设60个位点进行兽类和鸟类物种多样性本底资源调查。在成功回收数据的58个位点上,经过19 252个相机工作日调查后, 共拍摄到45种野生鸟兽, 隶属8目20科, 其中国家I级和国家II级重点保护野生动物分别有6种和11种, 被ICUN红色名录评估为濒危 (EN) 、易危 (VU) 和近危 (NT) 的物种分别为4种、3种和5种。兽类中以食肉目物种数最多 (6科10种) , 偶蹄目次之 (4科7种) 。相对多度指数最高的兽类物种是中华鬣羚 (Capricornis milneedwardsii, RAI = 19.58) , 其次是猪獾 (Arctonyx collaris, RAI = 11.58) 和黄喉貂 (Martes flavigula, RAI = 5.56) 。相对多度指数最高的鸟类物种是血雉 (Ithaginis cruentus, RAI = 9.18) , 其次是灰头鸫 (Turdus rubrocanus, RAI = 3.27) 和绿尾虹雉 (Lophophorus lhuysii, RAI = 2.91) 。相较于米亚罗保护区的历史资料, 本调查新增了2种兽类和4种鸟类的分布纪录, 分别是黄鼬(Mustela sibirica)、香鼬 (M. altaica) 、淡背地鸫 (Zoothera mollissima) 、小虎斑地鸫 (Z. dauma) 、白眉林鸲 (Tarsiger indicus) 和灰头绿啄木鸟 (Picus canus) 。调查初步掌握了米亚罗保护区鸟兽的物种组成和种群状况, 为邛崃山系中部保护区群的区域性生物多样性评估与保护规划提供了基础资料与数据支持。

Abstract:

Biodiversity monitoring on mammals and birds are of great importance to the regional biodiversity assessment. From May 2018 to June 2019, we deployed 60 camera traps in 60 1km × 1km in Miyaluo Provincial Nature Reserve, Sichuan Province, to investigate its terrestrial mammals and birds. With an extensive survey effort of 19 252 camera-days from 58 camera stations with valid data, we identified 45 wild mammal and bird species belonging to 8 orders and 20 families. There were 6 and 11 species that are listed as Class Ⅰ and Class II of national protected wildlife species, respectively. Four species were categorized as Endangered and three as Vulnerable by IUCN Red List. For mammals, Carnivora was the order with the highest species richness (10 from 6 families), followed by Artiodactyla (7 from 4 families). According to the relative abundance index (RAI), the three most abundant mammal species were Chinese serow (Capricornis milneedwardsii, RAI = 19.58), hog badger (Arctonyx collaris, RAI = 11.58) and yellow-throated marten (Martes flavigula, RAI = 5.56). For birds, the three most abundant birds were blood pheasant (Ithaginis cruentus, RAI = 9.18), chestnut thrush (Turdus rubrocanus, RAI = 3.27) and Chinese monal
(Lophophorus lhuysii, RAI = 2.91). Comparing with historical records of Miyaluo, our results added 2 mammal species and 4 avian species, including Siberian weasel (Mustela sibirica), Altai weasel (M. altaica), plain-backed thrush (Zoothera mollissima), scaly thrush (Z. dauma), white-browed bush robin (Tarsiger indicus) and grey-headed woodpecker (Picus canus). Our data constructed the base of local biodiversity information for both community structure and relative abundance. The results will provide key basic information and support for the regional biodiversity assessment and conservation planning of the nature reserve network in central Qionglai Mountains.
