European Alder

This is the common alder of Great Britain and central Europe southward,

growing chiefly along water courses, in boggy grounds and upon moist

mountain slopes; introduced into the United States and occasionally

escaping from cultivation; sometimes thoroughly established locally. In

them are several trees 30-40 feet in height and 8-12 inches in diameter

at the ground, distinguishable at a glance from the shrubby native

alders by their greater size, more erect habit, and darker trunks.
