Abstract

This study focuses on bird monitoring in woodlots using two monitoring methods. Woodlots are located on the border of the Highlands Region and the South Moravian Region in the heterogeneous wooded landscape. Birds were monitored in 11 woodlots using two approaches – line transect and camera traps. The line transects took place between 2020 and 2022 in the spring and autumn, and monitoring with camera traps took place from March 2022 to December 2023. In the woodlots, spatial and structural characteristics such as height, width, length, circumference, and area of the woodlot stand were measured. Processing of the data obtained was carried out in the GIS system and overall evaluation in the statistical program R and Canoco 5 using the GLMM and pCCA methods. We revealed that each bird monitoring method captured a different spectrum of bird species depending on the woodlot geometry. The bird species composition of long, narrow and bushy woodlots was better matched by species recorded by camera traps, and the species composition of wide woodlots with taller and older forest stands was better matched by species records from transect. Regarding the use of traditional ornithological methods and camera traps, for the best results, it is advisable to combine both methods.
光诱捕器是否是研究作为文化景观中特定林木植被的灌木丛中鸟类的合适方法?
本研究主要采用两种监测方法对林地中的鸟类进行监测。林地位于高地地区和南莫拉维亚地区的交界处,林木茂密。在 11 块林地中使用两种方法对鸟类进行了监测--线状横断面和相机陷阱。线状横断面监测于 2020 年至 2022 年的春季和秋季进行,相机陷阱监测于 2022 年 3 月至 2023 年 12 月进行。在林地中,测量了林分的高度、宽度、长度、周长和面积等空间和结构特征。在地理信息系统中对获得的数据进行了处理,并在统计程序 R 和 Canoco 5 中使用 GLMM 和 pCCA 方法进行了整体评估。我们发现,根据林地几何形状的不同,每种鸟类监测方法捕获的鸟类种类也不同。照相机诱捕器记录的鸟类与狭长和灌木丛林地的鸟类物种组成更匹配,而横断面记录的鸟类物种与林分较高、树龄较长的宽阔林地的鸟类物种组成更匹配。关于传统鸟类学方法和相机诱捕器的使用,为了达到最佳效果,建议将两种方法结合起来使用。
