Native to East Asia, Rosa multiflora is invasive in North America in most of the east and midwest, and along the Pacific Coast from California to British Columbia, as well as in New Zealand (CABI 2021). The USDA PLANTS Database cites listings of Rosa multiflora as invasive in Connecticut, prohibited in New York state, and a Class C noxious weed in Alabama.

A comparison of the Climate Match results and GBIF distribution (https://www.gbif.org/species/3003244) indicates that more than 50% of the species distribution lies outside of climatically matching areas.

7. Question 7
Yes

High
Munger (2002) reports that the species’ dense growth and vegetative spread crowds out and inhibits establishment and growth of desirable native plants.

8. Question 8
No
0
High
There is no information linking Rosa multiflora to increased fire risk or a change in fire regimes. The species resprouts following fire and may be promoted by fire (Munger 2002).

Amrine (2002) and Evans (1983) review reports of significant loss of pasturage due Rosa multiflora’s thorny and unpalatable thickets. The species can be an eye and skin irritant to cattle and other livestock (CABI 2021).

The species spreads clonally by layering and by tip-rooting (Jesse et al. 2010, Evans 1983).

12. Question 12
No

Medium
Since the species is capable of clonal spread via layering, broken or detached stem fragments are likely to take root under suitable conditions. However, none of the literature reviewed mentioned fragmentation, let alone suggested that this is a common method of reproduction.

19. Question 19
No

High
Hips generally do not split apart to release individual seeds, so wind dispersal is unlikely (Evans 1983). Since Rosa multiflora may invade riparian areas (WA NWCB 2019) water transport of hips may be a possibility but is not discussed in available sources.
