Alnus glutinosa, also known as the European Alder, is a versatile tree that is tolerant of clipping and maritime exposure, making it suitable for use in windbreaks or hedges. With a growth rate of 3 feet or more per year when young, it is quick to establish and able to grow in very poor soils, making it ideal for use in land reclamation projects. This tree also produces nitrogen nodules on its roots, making it an excellent source of biomass. Its dark green leaves make it perfect for wet soils, and it is native to most of Europe, including the UK and Fennoscandia, as well as locally in Southwest Asia. The common alder is famous for its symbiotic relationship with the nitrogen-fixing bacterium, Frankia alni, which improves soil fertility. Additionally, the tree provides food and shelter to wildlife, and its timber is used for underwater foundations, paper, joinery, and carving. Overall, the European Alder is an excellent choice for those seeking a hardy and versatile tree that benefits both the environment and local wildlife.
