Alder

Common or black alder occurs throughout most of Europe and across Russia to Siberia. Its range also includes the Caucasus, Iran, Turkey and North Africa, where it is native to Tunisia, Algeria and Morocco. It has been introduced to North America, probably during colonial times, and has become naturalised in eastern Canada and the northeast of the USA.
