Lobaria quercizans grows on old-growth hardwood trees in eastern Asia and eastern
North America. In North American it has an Appalachian-Great Lakes distribution. It
is not found in Europe. In the Great Lakes area common habitat for this species is on
old-growth sugar maple and black ash. Threats to Lobaria quercizans are large-scale
logging that would eliminate areas of old-growth sugar maple and yellow birch.
