Abstract

A complete seasonal time series of effective leaf area index (LAI 4 Ring) was obtained for 25 young individuals of Sorbus intermedia (Ehrh.) Pers., 1806 in an urban botanical garden using digital hemispherical photography (DHP) throughout the 2025 growing season (May–October). The mean seasonal effective LAI was 1.51 ± 0.31 (range 0.66–3.85). Repeated Measures ANOVA confirmed highly significant seasonal changes (F = 31.90; p < 10⁻¹⁶). The dataset provides validated ground truth data for urban ecosystem modelling and remote sensing calibration.
