DISTRIBUTION AND OCCURRENCE
SPECIES: Vaccinium caespitosum | Dwarf Huckleberry 



GENERAL DISTRIBUTION : 
Dwarf huckleberry grows from Labrador, westward through subarctic North
America to south-central Alaska [8,40].  It extends southward through
the Cascades into California and through the Rocky Mountains to Colorado
and New Mexico [33,40].  In eastern North America, dwarf huckleberry
grows southward through New England to New York and reaches portions of
northern Michigan and Minnesota to the west [8,61,68].  Disjunct
populations have been reported in certain mountainous areas of northern
Mexico [8].

HABITAT TYPES AND PLANT COMMUNITIES : 
Dwarf huckleberry occurs as an understory dominant or codominant in high
elevation spruce (Picea spp.)-fir (Abies spp.) forests throughout much
of western North America.  It also grows, often in great abundance, in
some relatively moist Douglas-fir (Pseudotsuga menziesia), quaking aspen
(Populus tremuloides), and lodgepole pine (Pinus contorta) communities.
Common understory codominants in these western forests include bog
Labrador tea (Ledum groenlandicum), grouse whortleberry (Vaccinium
scoparium), queencup beadlily (Clintonia uniflora), and bluejoint
reedgrass (Calamagrostis canadensis).  Dwarf huckleberry also occurs in
alpine heath communities and is codominant with species such as grouse
whortleberry, and pine dropseed (Blepharoneuron tricholepis) or other
forbs.  In the lower alpine zone of the West, this shrub, along with
grouse whortleberry, commonly dominates shrubfields which develop in
areas of prolonged snow cover [38].  In the East and North, it occurs in
black spruce (Picea mariana), balsam fir (A. balsamea)-white spruce (P.
glauca), paper birch (Betula papyrifera)-balsam fir, oak-maple
(Quercus-Acer spp.), and eastern hemlock (Tsuga canadensis) forests
[20,53].  In the East, blueberries (Vaccinium spp.) commonly dominate
the understory of many eastern hemlock, red maple (A. rubrum)-red oak
(Q. rubra), eastern white pine (Pinus strobus), sugar maple (A.
saccharum), and jack pine (Pinus banksiana)-red pine (P. resinosa)
forests.

Plant associates:  In the West, dwarf huckleberry commonly grows in
association with twinflower, queencup beadlily, Labrador tea, swordfern
(Polystichum spp.), huckleberries (V. membranaceum, V. globulare),
bluejoint reedgrass, elk sedge (Carex geyeri), and kinnikinnick
(Arctostaphylos uva-ursi) [62,74,75].  Common eastern understory
associates include maples (Acer spp.), blueberries (Vaccinium spp.),
lichens (Cladonia spp.), bog Labrador tea, wintergreen (Gaultheria
spp.), maianthemum (Maianthemum spp.), black crowberry (Empetrum
nigrum), mountain-laurel (Kalmia polifolia), and viburnum (Viburnum
spp.)  [20,44,45,53].
