DISTRIBUTION AND OCCURRENCE
SPECIES: Larix laricina | Tamarack 



GENERAL DISTRIBUTION : 
Tamarack is distributed across most of northern North America.  It
occurs from Newfoundland and Labrador northwest across northern Canada
to the northern Yukon Territory, south to northeastern British Columbia
and central Alberta, southeast to southern Minnesota, Wisconsin, and
northeastern Illinois, and east to New England [32].  A major disjunct
population occurs in the interior of Alaska between the Brooks Range to
the north and Alaska Range to the south [26].  It also occurs locally in
the mountains of West Virginia and western Maryland.

HABITAT TYPES AND PLANT COMMUNITIES : 
In northern Minnesota and throughout much of Canada, tamarack forms
extensive pure stands.  Throughout the rest of its range in the United
States it forms isolated pure stands or is a minor component of other
forest types [26].  In the northeastern United States, tamarack is
characteristically found in open and forested bogs, but it seldom
dominates in forested bog communities [9].  Throughout its range, black
spruce (Picea mariana) is usually associated with tamarack.  In Alaska,
black spruce and tamarack may codominate wet, lowland sites with shallow
permafrost [48].

Tamarack is sometimes a dominant tree in seral lowland communities.  It
has been listed as a community type (cts) dominant in the following
classifications:
