This data shows the canopy cover of 291 core plots for site A and B of the main experiment in the year 2024. Measurements for this data took place in early August 2024 before the deciduosu trees would start losing their leaves. This data was extracted using the Gap Light Analyzer (GLA) software (Frazer, G.W., Canham, C.D., and Lertzman, K.P. 1999) on wide-angle photograps taken with an 8mm on a DSLR camera. Pictures were taken as part of the MultiTroph SP4 subproject involving the study of cavity-nesting Hymenoptera communities and interactions. One picture per plot was taken, at ~1.8m above ground, with lens perpendicular to the gravitational horizontal plane, at one of the four corners of the core plot area (variable, depending on which corner the Hymenoptera trap nest was placed).

Fisheye photo with 8mm lens on DSLR (Olympus). One picture taken per plot, 291 core plots (147 plots Site A, 142 plots Site B) including all VIP plots. Pictures were taken in early August 2024 at ~1.8m from ground, with lens facing upwards perpendicular to gravitational horizontal plane. Pictures taken at one of the four corners of the core plot area. The choice of corner per plot is variable as it was dependent on the location of the cavity-nesting Hymenoptera traps of the SP4 project.
