DISTRIBUTION AND OCCURRENCE
SPECIES: Holodiscus dumosus | Bush Oceanspray 



GENERAL DISTRIBUTION : 
Bush oceanspray occurs from north-central Oregon east to Wyoming and
southward throughout much of the Great Basin to California, Nevada,
Arizona, New Mexico, and Chihuahua, Mexico [14,36].  Along the western
edge of its range, this species occurs essentially east of the Cascade
Range, extending southward to northwestern California and the central
Sierra Nevada [14,25].

HABITAT TYPES AND PLANT COMMUNITIES : 
Bush oceanspray has been used as an indicator of climax conditions on
rocky sites in both nonforested and forested communities throughout its
range.  A bush oceanspray shrubland series has been described for steep,
talus slopes in Colorado; habitat types include bush oceanspray/Thurber
fescue (Festuca thurberi) and bush oceanspray/wax current (Ribes cereum)
[17].  In the Pacific Northwest, Erhard [7] has described a curlleaf
mountain-mahogany/bush oceanspray (Cercocarpus ledifolius/Holodiscus
microphyllus var. glabrescens) habitat type associated with basalt lava
flows.  Along the east slope of the Cascades in Oregon, Hopkins and
Kovalchik [16] have described a western juniper/big sagebrush-bush
oceanspray/bluebunch wheatgrass-arrowleaf (Juniperus occidentalis/
Artemisia tridentata-Holodiscus dumosa/Pseudoroegneria spicata-
Balsamorhiza sagittata) community type.

On high-elevation sites in the southern Rocky Mountains, bush oceanspray
is listed as the understory dominant in forested scree habitat types
within the white fir (Abies concolor), alpine fir (A. lasiocarpa), and
Douglas-fir (Pseudotsuga menzeisii) series; it is also utilized as a
phase indicator in the following Southwestern forested habitat types
[1]:

     white fir/big tooth maple (Acer grandidentatum)
     white fir/Rocky mountain maple (A. glabrum)
     white fir/Gambel oak (Quercus gambelii)
     Douglas-fir/Gambel oak
     white fir-Douglas-fir/Rocky Mountain maple
