摘要:

近年来, 红外相机技术已被广泛应用于国内外自然保护地内地栖鸟兽的物种编目和动态评估。本文以广东车八岭国家级自然保护区为例, 探讨基于红外相机技术如何进行保护区全境大中型兽类和雉鸡类的物种编目清查与评估。通过对车八岭保护区全境为期1年的调查, 共记录兽类和雉鸡类18种, 其中兽类15种, 鸡形目鸟类3种。基于物种累计曲线, 采用全年数据所需的最小调查网格数、最少调查相机日均要少于雨季或旱季, 而旱季调查需要的最小调查网格数和最少调查相机日比雨季更少。通过红外相机图像数据获得了车八岭保护区的大中型兽类和地栖雉鸡类物种名录、物种丰富度、每个物种的相对多度、分布图和凭证标本等重要内容。

Abstract:

Infrared-camera technology (i.e. camera trapping) has been widely used recently for species inventories and related assessment of terrestrial vertebrates in protected areas across the world. In this study, we provide a case study for how to assess species inventory data of terrestrial birds and mammals based on camera trapping in the Chebaling National Nature Reserve, Guangdong Province. Using camera trapping data from 2017 across the whole area with 80 grids (grid size, 1 km 2) in the reserve, we recorded 15 medium and large mammal species and three pheasant species. Based on species accumulation curves as a function of grids and camera days when 90% of expected species richness was recorded in the reserve, the minimum grids with fixed camera days and the minimum camera days with fixed grids were less during the wet season (June-August) than during the dry season (October-December). Moreover, the minimum grids with fixed camera days and the minimum camera days with fixed grids during the dry season were less than during the wet season. Based the camera trapping data, the species inventory assessment in the reserve can cover species lists and species richness of terrestrial birds and mammals, as well as relative abundance, distribution and voucher images of each species. Therefore, the Chebaling case based on the whole-area species inventory and assessment can provide technical references for China’s natural protected areas.
