DISTRIBUTION AND OCCURRENCE
SPECIES: Thuja occidentalis | Northern White-Cedar 



GENERAL DISTRIBUTION : 
Northern white-cedar occurs in southeastern Canada and the adjacent
northern United States.  It is distributed from southwestern Nova
Scotia, Prince Edward Island, New Brunswick, the Gaspe Peninsula in
Quebec, and Anticosti Island in the Gulf of Saint Lawrence; west to
northern Ontario and southeastern Manitoba; south to southeastern
Minnesota and northern Illinois; and east through extreme northwestern
Indiana, Michigan, and the New England states.  Island populations occur
in the Appalachian Mountains in western Pennsylvania, West Virginia,
Virginia, and eastern Tennessee.  Local populations also occur in
west-central Manitoba, Wisconsin, Minnesota, Illinois, and Ohio [26,33].
Historical evidence indicates that northern white-cedar is native to
North Carolina as well, but no known native population occurs there now
[10].

HABITAT TYPES AND PLANT COMMUNITIES : 
Northern white-cedar is an important species in the wet-mesic coniferous
forests of the northern lowlands [14].  It is often present in the
ecotone between sphagnum bog and upland hardwood communities [15].  It
may dominate rich swamp forests, poor swamp forests, and the cedar
string bog and fen complex [24].
