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.
