DISTRIBUTION AND OCCURRENCE
SPECIES: Vaccinium ovalifolium | Ovalleaf Huckleberry 



GENERAL DISTRIBUTION : 
Ovalleaf huckleberry grows from Alaska to the Cascades of Washington and
Oregon, eastward to Idaho and Montana [34].  This shrub also occurs
across much of the Pacific Rim, from the Aleutians to Japan, and reaches
parts of mainland eastern Asia [63].  Disjunct populations are common
throughout eastern Canada and the Great Lakes Region [4].  In eastern
North America, ovalleaf huckleberry occurs sporadically from northern
Quebec, Nova Scotia, and Newfoundland, southwestward to northern Michigan
[34].

HABITAT TYPES AND PLANT COMMUNITIES : 
In the West, ovalleaf huckleberry occurs in coastal montane or interior
forests dominated by western redcedar (Thuja plicata), western hemlock
(Tsuga heterophylla), mountain hemlock (Tsuga mertensiana), Sitka spruce
(Picea sitchensis), Pacific silver fir (Abies amabilis), and
yellow-cedar (Chamaecyparis nootkatensis).  Common understory
codominants include blue huckleberry (V. membranaceum), Alaska
huckleberry (V. alaskaense), Oregon oxalis (Oxalis oregana), western
swordfern (Polystichum munitum), and bog Labrador tea (Ledum
glandulosum).  In the East, ovalleaf huckleberry occurs in montane
forests dominated by such species as balsam fir (A. balsamea) and paper
birch (Betula papyrifera) [49].

Understory associates:  Species which commonly occur with ovalleaf
huckleberry in western North America include menziesia (Menziesia
ferruginea), five leaf bramble (Rubus pedatus), queencup beadlily
(Clintonia uniflora), blue huckleberry, beargrass (Xerophyllum tenax),
red huckleberry (V. parvifolium), devil's club (Oplopanax horridus),
western swordfern (Polystichum munitum), lady fern (Athyrium
filix-femina), threeleaf foamflower (Tiarella trifoliata), and Oregon
oxalis (Oxalis oregana) [25,33,51,67].  Overall species diversity is low
on many drier ovalleaf huckleberry sites [26].  Common eastern
understory associates include bunchberry (Cornus canadensis), woodfern
(Dryopteris spinulosa), twinflower (Linnaea borealis), yellow beadlily
(Clintonia borealis), sedges (Carex spp.), American starflower
(Trientalis borealis), Canada beadruby (Maianthemum canadense), and
