Frequent species show the percentage of occurrence of species in each habitat, with higher values indicating more observations within the total number of samples. Indicator species show the fidelity of species to each habitat, with higher values indicating a stronger association, based on the IndVal metric (Dufrêne & Legendre, 1997). All species values were obtained from numerical classification (Jiménez-Alfaro et al. 2025). The classification of anthropogenic habitats (EUNIS code “V”) was conducted separately (Fernández-Pascual et al. 2025).
