HABITAT TYPES AND PLANT COMMUNITIES :
Rose spirea occurs mainly in riparian habitats such as swamps, mud
flats, shrub carrs, marshes, bogs, and along streams [8,17,18,23,44].
In British Columbia rose spirea is found in rush (Juncus spp.)-sedge
(Carex spp.)-quillwort (Isoetes spp.) and shrub carr community types
[8,18]. Common associates include Rocky Mountain maple (Acer glabrum),
Sitka willow (Salix sitchensis), salmonberry (Rubus spectabilis), salal
(Gaultheria shallon), sweet gale (Myrica gale), and bog rush (Juncus
effusus) [2,28].
In Washington a rose spirea-bog blueberry (Vaccinium
uliginosum)/sedge community type is described. Common associates
include swordleaf rush (Juncus ensifolius), blister sedge (Carex
vesicaria), Sitka sedge (C. sitchensis), slough sedge (C. obnupta),
common willowweed (Epilobium glandulosum), and kneeling angelica
(Angelica genuflexa) [19]. Rose spirea is also a member of a field
horsetail (Equisetum arvense)-skunkcabbage (Veratrum californicum) swamp
association. Associates include Sitka alder (Alnus viridis ssp.
sinuata), black twinberry (Lonicera involucrata), and red-osier dogwood
(Cornus sericea) [16].
Associates of rose spirea in Washington and Oregon forest communities
include dwarf huckleberry (Vaccinium caespitosum), blue wildrye (Elymus
glaucus), deer fern (Blechnum spicant), bracken fern (Pteridium
aquilinum), western yarrow (Achillea millefolium), widefruit sedge
(Carex eurycarpa), Wood's rose (Rosa woodsii), and bristly black currant
(Ribes lacustre) [12,29,30].
In California rose spirea occurs in sphagnum bog, north coast
riparian scrub, and freshwater marsh communities [23,44]. Common
associates include bigleaf maple (Acer macrophyllum), Pacific wax-myrtle
(Myrica californica), Hooker willow (Salix hookeriana), Hinds willow (S.
hindsiana), sedge (Carex spp.), bear sedge (C. arcta), round-leaved
sundew (Drosera rotundifolia), and coast Labrador tea (Ledum glandulosum
var. columbiana) [23,44].
In eastern Idaho and western Montana, rose spirea is dominant in
herbaceous wetland communities [41,42]. In Montana a rose spirea
community type has been described [4,17]. Rose spirea is dominant
in a thinleaf alder community type [4]. Common associates in Montana
include Booth willow (Salix boothii), Geyer willow (S. geyeriana),
Wood's rose, western polemonium (Polemonium occidentale), beaked sedge
(Carex rostrata), inflated sedge (C. vesicaria), reed canarygrass
(Phalaris arundinacea), and creeping bentgrass (Agrostis stolonifera)
[4,17].
The following publications list rose spirea as a community dominant:

California's coastal zone [44]
MANAGEMENT CONSIDERATIONS
SPECIES: Spiraea douglasii
IMPORTANCE TO LIVESTOCK AND WILDLIFE :
Rose 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 rose spirea is browsed by
black-tailed deer [5,8].
PALATABILITY :
In Oregon rose 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 rose spirea emergent shrub community type [52]. In
British Columbia rose 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/rose
spirea/widefruit sedge and lodgepole pine/rose 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 rose spirea for riparian revegetation
programs in the Pacific Northwest. In a black cottonwood (Populus
trichocarpa) riparian community, rose spirea seedlings were planted
in the fall of 1980 and had a 27 percent survival rate. In 1988 percent
cover of rose spirea had increased [6]. In Oregon rose 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
OTHER MANAGEMENT CONSIDERATIONS :
In Oregon rose spirea is sensitive to trampling and soil compaction
[4,32]. The riparian lodgepole pine/rose spirea/forb association
has been overgrazed in Oregon. Rose spirea may be eliminated with
continued overuse [29].
BOTANICAL AND ECOLOGICAL CHARACTERISTICS
SPECIES: Spiraea douglasii
GENERAL BOTANICAL CHARACTERISTICS :
Rose spirea is a rhizomatous, deciduous shrub with erect, spreading
stems 3 to 6 feet (1-1.8 m) tall [17,35,40]. Leaves are 1 to 4 inches
(3-10 cm) long [20,35]. Seeds are 0.08 inch (2 mm) long [40].
Rosespirea forms adventitious roots after burial [1].
RAUNKIAER LIFE FORM :
Phanerophyte
REGENERATION PROCESSES :
Rose spirea is a rhizomatous shrub that often forms dense colonies
[1,4,32]. It will sprout from the stem base and root crown following
disturbance [4,29]. In Washington following the May 18, 1980 volcanic
eruption of Mount St. Helens, rose spirea showed extensive rhizome
development in the tephra (volcanic aerial ejecta) and contained one to
five adventitious roots per centimeter of stem 1 year after burial.
Maximum adventitious root length of rose spirea was 3.6 inches (9
cm) [1].
Rose spirea produces small seeds that are probably dispersed via
animals and strong winds [40].
SITE CHARACTERISTICS :
Rose spirea occurs in riparian areas including wet meadows,
floodplains, terraces, bogs, swamps, and along streams, rivers, lakes,
springs, and ponds [4,12,17,23,24].
Rose spirea grows best on moist to semiwet soils with good drainage
[20,28,29,32,35]. It grows best on loam and sandy loam soils, but
occurs on silty clay, clay loam, and gravelly substrates as well
[17,19,23,29,42]. Rose spirea is tolerant of permanently
water-logged soils (peat) and widely fluctuating water tables [23,28].
Elevations for rose spirea are as follows:
feet meters
California 4,620-6,435 1,400-1,950 [20,46]
Montana 3,760-6,700 1,147-2,044 [4,35]
Oregon 2,200-5,800 660-1,740 [29]
Washington 2,500-5,000 750-1,500 [19]
SUCCESSIONAL STATUS :
Rose spirea occurs mostly in seral communities [2,4,7,27,37]. It is
generally shade intolerant [28], but horticultural specimens have been
described as shade tolerant [11,20]. In British Columbia rose
spirea is a pioneer species in disclimax communities maintained by
avalanches [2]. In southwestern British Columbia and northwestern
Washington, rose spirea is a pioneer species on clearcut sites
[27,37]. In northwestern Montana a rose spirea community type may
be seral to an as yet undefined thinleaf alder/rose spirea habitat
type [4].
Rose spirea often forms dense impenetrable thickets in riparian
areas [4]. In Washington rose spirea usually occurs in mosaics with
other hydric and mesic non-forest species in riparian forest openings
[19].
SEASONAL DEVELOPMENT :
In California rose spirea flowers from June to September [40].
FIRE ECOLOGY
SPECIES: Spiraea douglasii
FIRE ECOLOGY OR ADAPTATIONS :
Rose spirea is moderately resistant to fire [32] and sprouts readily
from the stem base and rhizomes after fire [4,17,29,32]. In
presettlement times, wildfires were "probably common" in rose spirea
communities of riparian areas in Montana and Oregon; soils were usually
dry by mid-summer, allowing fires from adjacent uplands to encroach upon
the stand [17,29]. Fires were probably infrequent in the thinleaf
alder-rose spirea association in Oregon [29].
POSTFIRE REGENERATION STRATEGY :
Small shrub, adventitious-bud root crown
Rhizomatous shrub, rhizome in soil

which this species may occur by entering the species name in the
FEIS home page under "Find Fire Regimes".
FIRE EFFECTS
SPECIES: Spiraea douglasii
IMMEDIATE FIRE EFFECT ON PLANT :
Rose spirea is probably topkilled by most fires and killed by
severe fires.
PLANT RESPONSE TO FIRE :
The literature contains few reports describing rose spirea after
fire. Because of its sprouting ability, it probably survives most
fires. In central British Columbia rose spirea was present with
shinyleaf spirea (Spiraea betulifolia var. lucida) in seral Engelmann
spruce (Picea engelmannii)-fir (Abies spp.) stands. Relative density of
the Spiraea spp. in plots 4 to 22 years after fire was 4 percent; in
plots 37 to 75 years after fire, it was 9 percent [13]. In British
Columbia McMinn [38] studied a site in a western hemlock/Sitka spruce
forest burned in 1861 and again in 1931. By 1948 rose spirea had
formed dense thickets with salmonberry and thimbleberry.
