SPECIES : Amelanchier alnifolia | Saskatoon Serviceberry 


GENERAL DISTRIBUTION : 
Saskatoon serviceberry is distributed from east-central California north
to southern Alaska; east to Ontario and southwestern Quebec; and south
to southern Colorado and Utah [31,44,52,53,66,88].

Varieties of Saskatoon serviceberry overlap in distribution.  Their
geographical ranges are as follows:

The typical variety of Saskatoon serviceberry (Amelanchier alnifolia
var. alnifolia) occurs from southern Alaska south to southern Oregon,
mostly east of the Cascade Range, and east to the Dakotas, Nebraska, and
Colorado.  Amelanchier alnifolia var. humptulipensis occurs on the
western slope of the Cascade Range in British Columbia and Washington
[52].

Cusick's serviceberry is distributed on the east slope of the Cascade
Range from British Columbia to Oregon and east in the Rocky Mountains to
Wyoming [52].

Dwarf serviceberry is distributed from southeastern Washington south to
northeastern California and east to Montana and Colorado [51,52].

Pacific serviceberry is distributed west of the Cascade and Sierra
Nevada ranges from central California to Alaska and east to northern
Idaho and western Montana [21,51,52].

HABITAT TYPES AND PLANT COMMUNITIES : 
Saskatoon serviceberry is common in lower-elevation coniferous forests
[91].  It also occurs in montane chaparral [14,21], mountain shrub
[91,103], and the upper limits of pinyon-juniper (Pinus-Juniperus spp.)
communities [91].  In plains grasslands it mostly occurs in wooded
draws, grassland-woodland interfaces, and riparian zones [39].

Associated species:  Riparian - Saskatoon serviceberry is common in
riparian areas throughout its distribution.  Riparian associates in the
Northern Rocky Mountains include white alder (Alnus rhombifolia) [75],
hawthorn (Crataegus douglasii), chokecherry (Prunus virginiana), bitter
cherry (P. emarginata), Greene mountain-ash, and elderberry (Sambucus
spp.) [1].

Montana chaparral - Associates in montane chaparral of California
include creeping snowberry (Symphoricarpus mollis), Sierra currant
(Ribes nevadensis), Sierra gooseberry (R. roezlii), California rose
(Rosa californica), Sierra plum (P. subcordata), Sierra mountain-misery
(Chamaebatia foliolosa), and conifer saplings, especially ponderosa pine
(Pinus ponderosa) [14].

Gambel oak (Quercus gambelii) - Mountain-mahogany (Cercocarpus spp.),
chokecherry, and snowberry (Symphoricarpos spp.) are common associates
throughout the Gambel oak type [21].  Associates in Gambel oak/Saskatoon
serviceberry habitat types of Colorado include Oregon-grape (Mahonia
repens), chokecherry, mountain snowberry (S. oreophilis), and elk sedge
(Carex geyeri) [4].

Pinyon-juniper - Common associates include singleleaf pinyon (Pinus
monophylla), Utah juniper (J. osteosperma), bitterbrush (Purshia
tridentata), Stansbury cliffrose (P. mexicana var. stansburiana), and
curlleaf mountain-mahogany (Cercocarpus ledifolius) [107].  Associates
in singleleaf pinyon/Saskatoon serviceberry communities in southeastern
Nevada include greenleaf manzanita (Arctostaphylos patula), big
sagebrush (Artemisia tridentata), black sagebrush (A. nova), rubber
rabbitbrush (Chrysothamnus nauseosus), Gambel oak, and Stansbury phlox
(Phlox stansburyi) [15].

Bur oak (Q. macrocarpa) - In Bur oak/chokecherry woodland of North
Dakota, associates of Saskatoon serviceberry include green ash (Fraxinus
pennsylvanica), western snowberry (S. occidentalis), and northern
bedstraw (Galium boreale) [39,40].

Colorado - Associates in bigtooth aspen (Populus angustifolia)/Saskatoon
serviceberry habitat types include Rocky Mountain maple (Acer glabrum),
water birch (Betula occidentalis), and mountain snowberry.  Associates
in blue spruce (Picea pungens)/Saskatoon serviceberry types include
red-osier dogwood (Cornus sericea), Wood's rose (Rosa woodsii), elk
sedge, Thurber fescue (Festuca thurberi), and Lapland cornel (Cornus
suecica) [4].

Alaska - Saskatoon serviceberry is uncommon in Alaska [53].  Associates
in white spruce-black spruce-quaking aspen (Picea glauca-P.
mariana-Populus tremuloides) on the Kenai Peninsula include paper birch
(B. papyrifera), Bebb willow (Salix bebbiana), Scouler willow (S.
scouleriana), bog birch (B. glandulosa), and Greene mountain-ash [89].
