SPECIES: Spiraea douglasii | Douglas' Spirea
WOOD PRODUCTS VALUE : NO-ENTRY 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 fall [4,17]. In western Washington and Oregon Douglas' spirea is browsed by black-tailed deer [5,8]. PALATABILITY : In Oregon Douglas' spirea has a low palatability rating [29]. NUTRITIONAL VALUE : NO-ENTRY COVER VALUE : In Washington a breeding population of long-billed marsh wrens was found nesting in a Douglas' spirea emergent shrub community type [52]. In British Columbia Douglas' spirea is a component of the western hemlock-Sitka spruce habitat type which is important grizzly bear habitat [2]. 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 [29]. VALUE FOR REHABILITATION OF DISTURBED SITES : Carlson [6] 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 [6]. 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 [48]. OTHER USES AND VALUES : NO-ENTRY 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 [29].
