Site Characteristics
Nootka rose is commonly found in moderately dry to moist climates in submontane to montane zones. It occurs on nitrogen-rich, fresh to very moist soils. It frequently occurs in floodplains, open streambanks, and meadows [24]. It is sporadic in open-canopy forests with fluctuating groundwater tables. It is occasionally found on brackish-water sites or sites exposed to ocean spray [15]. Nootka rose grows best at pH ranges of 5.6 to 7.0. It thrives on moderately fertile, well-drained clayey-loam, sandy-loam, or sandy soils [14].
Plant Communities
Nootka rose is listed as a dominant understory shrub in the following publication:
Plant communities and soils of north slopes in the palouse region of eastern Washington and northern Idaho [2].
Common plant associates of Nootka rose include common snowberry (Symphoricarpos albus), red-osier dogwood (Cornus sericea), quaking aspen (Populus tremuloides), and black cottonwood (P. trichocarpa) [2,5].
Botanical Description

Nootka rose.
Nootka rose is a native, deciduous, perennial shrub 3 to 6 feet (0.9-1.8 m) tall with erect or trailing stems. Nootka rose reaches its maximum height within 10 years. Stems and branches are prickly to unarmed. Leaves are compound and have five to seven leaflets. The fruits contain several long, hairy achenes. Roots are deep. Nootka rose has rhizomes [13,14,17].
Raunkiaer Life Form (Raunkiaer 1934)
- Phanerophyte
- Chamaephyte
- Geophyte
Seasonal Development
Nootka rose flowers from May through July [8,19]. Fruits ripen in early fall and remain on the plant through winter [13].
Regeneration Processes
Sexual: Nootka rose attains sexual maturity at 2 to 5 years of age. Good seed crops are produced about every other year. Nootka rose is a seedbanking species. Seeds exhibit seedcoat dormancy and require a combination of warm and cold stratification or mechanical disturbance for germination. Seeds are dispersed by birds and mammals [13,14].
Asexual: Nootka rose sprouts from the root crown and rhizomes [13,14].
Successional Status
Nootka rose is tolerant of both sun and shade. It shows increased growth and fruit production with increasing light. Nootka rose increases in cover with canopy closure, but may produce less fruit [14].
Immediate Fire Effects
Nootka rose is top-killed by fire. Shallowly buried root crowns and rhizomes of Rosa species, including Nootka rose, may be killed by severe fire [14].
Postfire Regeneration Strategy (Stickney 1989)
- Small shrub, adventitious-bud root crown
- Rhizomatous shrub, rhizome in soil
- Ground residual colonizer (on-site, initial community)
- Initial-offsite colonizer (off-site, initial community)
Fire Adaptations
Nootka rose sprouts from rhizomes and root crowns following fire. It also regenerates from onsite or transported seed [14].
Plant Response to Fire
Nootka rose may increase or decrease following fire. Rosa species of British Columbia, including Nootka rose, usually initially decrease in cover after wildfire. Cover gradually increases, and then declines again as the canopy closes [14]. In a Douglas-fir/ninebark habitat type in Idaho, Nootka rose cover was greater on burned sites or sites logged and then burned than on undisturbed sites. Cover was less, however, than on logged or grazed sites [7]. In aspen and aspen-mixed conifer stands in Idaho and Wyoming, prescribed fires of low to high severity caused a decrease in cover of Nootka and Wood's rose (Rosa woodsii) in postfire year 1. Rose biomass in postfire year 2 was near prefire levels [25]. In Washington and Oregon, burning had little effect on abundance of Nootka rose. Multiple fires can significantly reduce cover of rose species [14].
The Research Project Summary Understory recovery after low- and high-intensity fires in northern Idaho ponderosa pine forests provides information on prescribed fire and postfire response of plant community species including Nootka rose.

Importance to Wildlife and Livestock
Nootka rose is important wildlife browse. Mule deer, white-tailed deer, elk, moose, caribou, bighorn sheep, bears, coyotes, and various rodents eat the fruits. Squirrels, mice, beavers, and porcupines eat the twigs and leaves [1,4,14].
Palatability and Nutritional Value
Nootka rose fruits are preferred by deer, elk, and squirrels [3,14].
Cover Value
Nootka rose thickets are used for nesting and escape cover by birds and small mammals [14]. Nootka rose provides good cover for waterfowl in Wyoming [8].
Value for Rehabilitation or Restoration of Disturbed Sites
Nootka rose has successfully been used for rehabilitating disturbed sites at Columbia River Gorge, Oregon [23].
Other Uses
No entry.
Other Management Considerations
In a Douglas-fir/ninebark (Pseudotsuga menziesii/Physocarpus malvaceus) habitat type in Idaho, Nootka rose cover was greater on disturbed sites than on undisturbed sites. Average cover was highest (7.7 percent) on grazed sites [7]. In 16- to 20-year-old lodgepole pine (Pinus contorta) regeneration in northeastern Utah, Nootka rose productivity was little affected by thinning or clearcutting [3].
Spring and fall foliar applications of herbicides control Rosa species [14].
