Alnus glutinosa – Alder

Alnus glutinosa (commonly known as the black alder or European alder) is a deciduous tree native to Europe, western Asia, and northern Africa. It typically grows to a height of 15 to 25 meters, though it can sometimes reach up to 30 meters. The tree is characterized by its smooth, dark bark and rounded leaves with serrated edges. It thrives in wet and marshy areas, often found along rivers and in wet woodlands. Alnus glutinosa is valued for its ability to improve soil fertility through nitrogen fixation and its use in environmental restoration projects.
