BETA-FOR_SP6_Bees_2022/2023

This dataset includes records of bee (Apidae) species collected using standardized pan trap sampling across the 234 BETA-FOR patches. In each patch, three clusters of one yellow, white, and blue pan trap were placed along a transect crossing the patch center, with at least 15 m between clusters. Traps were filled with water and a drop of detergent and exposed for 48 hours per sampling round. Sampling was conducted during three periods (April, June, and July) across two consecutive years. In 2022, 180 patches were sampled across the forest pairs U01–U03, B04–B07, and P08. In 2023, the remaining 54 patches in S10, H09, and L11 (Saarland, Hunsrück, Lübeck) were sampled following the same protocol, with sampling limited to April and June. All collected bee specimens were sorted and identified to species level. The dataset comprises a total of 4,838 individuals representing 100 bee species.
