DISTRIBUTION AND OCCURRENCE
SPECIES: Oxalis montana | Common Woodsorrel 



GENERAL DISTRIBUTION : 
In Canada, common woodsorrel occurs from Manitoba east to southern
Labrador and south to Nova Scotia [32].  In the United States, its range
extends from Minnesota across the North Central States to New England
[22].  Its range continues south along the Appalachian Mountains to
North Carolina and Tennessee [10,22].

HABITAT TYPES AND PLANT COMMUNITIES : 
Common woodsorrel is a dominant understory species in red spruce (Picea
rubens) and balsam or Fraser fir (Abies balsamea or A. fraseri) forests
of the Appalachian Mountains, which are part of the boreal forest
formation [29,34].  Common woodsorrel is an indicator for several forest
habitat types or site types in the balsam and Fraser fir phases
[3,5,11,15].

Common woodsorrel is dominant in the northern hardwoods forest, red or
sugar maple-yellow birch-American beech (Acer rubrum or A.
saccharum-Betula lutea-Fagus grandifolia) [7,24].  It is also a dominant
species in the transition plant associations between the boreal forest
and the northern hardwoods [19,37].  It is a minor component of the
riparian communities in the northern hardwood forests [6].

Common woodsorrel is subdominant in seral communities of black cherry
(Prunus serotina)-red maple [36].  In northern Wisconsin, common
woodsorrel is a dominant forb in the association of eastern
hemlock-false lily-of-the-valley-goldthread (Tsuga
canadensis-Maianthemum canadense-Coptis groenlandica) [13,20].  In white
cedar (Thuja occidentalis) communities, common woodsorrel is a minor
component with a corresponding low importance value of 0.4 [28].

Frequent herbaceous codominants are false lily-of-the-valley,
goldthread, starflower (Trientalis borealis), and woodferns (Dryopteris
spp.) [8,29,31,37,41].
