Holm Oak
Quercus ilexAlso known as Holly Oak, Mediterranean Evergreen Oak, Ballota Oak
Holm oaks form the backbone of Mediterranean evergreen forests, displaying dense, dark green foliage that stays on the branches year-round. Young shoots and lower leaves often feature sharp, holly-like spines to deter grazing animals, whereas mature upper canopy leaves remain smooth and leathery. Their rich acorn crops sustain diverse wildlife, from seed-dispersing birds to forest mammals.

Responsible observation
- Leaf Dimorphism: Compare lower prickly leaves with higher smooth leaves to see herbivore defense adaptations.
- Acorn Spotting: Look for short-stalked acorns maturing in early autumn on lower outer branches.
- Root Association: Scan the surrounding soil in late autumn for signs of mycorrhizal fungal activity.
