DISTRIBUTION AND OCCURRENCE
SPECIES: Salix lutea | Yellow Willow 



GENERAL DISTRIBUTION : 
Yellow willow is found at low to mid-elevations from Alberta to
Manitoba, south to western Kansas and New Mexico, west to Arizona and
California, and north along the Sierra Nevada Mountains to eastern
Washington.  It is lacking in the Great Basin [14,17,37].

HABITAT TYPES AND PLANT COMMUNITIES : 
Yellow willow typically occurs as a pioneer or early seral species along
the banks of rivers or streams.  In these riparian comminities, it is
often found with cottonwoods (Populus spp.) and other willows (Salix
spp.).  

Published classification schemes listing yellow willow as an indicator
species or as a dominant part of the vegetation in community types or
dominance types are presented below.

  Wyoming, South Dakota, Nebraska, Colorado, and Kansas [25]

  Wyoming [46]
Riparian community type classification of norethern Utah and adjacent
  Idaho [47]

Associates:  In Idaho, yellow willow is generally confined to Wyoming
big sagebrush (Artemisia tridentata var. wyomingensis) and grass
vegetation zones, seldom extending into the forest, and avoiding cooler
mountain big sagebrush (A. tridentata var. vaseyana) zones [7].
Associated plants of Idaho, Montana, Utah, and Wyoming often include: 1)
overstory trees such as eastern cottonwood (P. deltoides), black
cottonwood (P. trichocarpa), water birch (Betula occidentalis), and
green ash (Fraxinus pennsylvanica), 2) shrubs such as sandbar willow (S.
exigua), Pacific willow (S. lasiandra), Booth willow (S.  boothii),
Drummond willow (S. drummondiana), Wood's rose (Rosa woodsii), red-osier
dogwood (Cornus sericea), and inland currant (Ribes oxyacanthoides ssp.
setosum), 3) very wet site understory herbs such as beaked sedge (Carex
rostrata) and field horsetail (Equisetum arvense), and 4) moist site
understory herbs such as alpine aster (Aster foliaceus), Richardson
geranium (Geranium richardsonii), and Kentucky bluegrass (Poa pratensis)
[7,19,46,47].
