SPECIES: Spiraea douglasii | Douglas' Spirea
WOOD PRODUCTS VALUE :
IMPORTANCE TO LIVESTOCK AND WILDLIFE :
Douglas' spirea has limited value as livestock forage because of
typically dense stands, high water tables, and scarcity of palatable
grasses [4,17]. It is sometimes eaten by livestock in the summer and
In western Washington and Oregon Douglas' spirea is browsed by
black-tailed deer [5,8].
In Oregon Douglas' spirea has a low palatability rating .
NUTRITIONAL VALUE :
COVER VALUE :
In Washington a breeding population of long-billed marsh wrens was found
nesting in a Douglas' spirea emergent shrub community type . In
British Columbia Douglas' spirea is a component of the western
hemlock-Sitka spruce habitat type which is important grizzly bear
habitat . In Oregon quaking aspen-lodgepole pine/Douglas'
spirea/widefruit sedge and lodgepole pine/Douglas' spirea/widefruit
sedge habitat types are utilized by livestock for bedding and shade.
These two habitat types are also important to deer, elk, and raptors
VALUE FOR REHABILITATION OF DISTURBED SITES :
Carlson  recommends Douglas' spirea for riparian revegetation
programs in the Pacific Northwest. In a black cottonwood (Populus
trichocarpa) riparian community, Douglas' spirea seedlings were planted
in the fall of 1980 and had a 27 percent survival rate. In 1988 percent
cover of Douglas' spirea had increased . In Oregon Douglas' spirea
was propagated as in situ hardwood cuttings (collected and planted
on-site the same day) in a Pacific silver fir (Abies amabilis) community
OTHER USES AND VALUES :
MANAGEMENT CONSIDERATIONS :
In Oregon Douglas' spirea is sensitive to trampling and soil compaction
[4,32]. The riparian lodgepole pine/Douglas' spirea/forb association
has been overgrazed in Oregon. Douglas' spirea may be eliminated with
continued overuse .
