Multiflora Rose

Multiflora Rose
http://www.nps.gov/plants/ALIEN/fact/romu1.htm
Country of Origin: China, Japan
History: Multiflora Rose is originally from eastern China and Japan and was introduced to the US as a horticultural ornamental that has escaped into the wild. It was also used as a control agent for soil erosion and planted along roadsides to limit headlight glare and as a crash barrier.
Intended Use: Erosion control, road barriers and horticultural applications
Mode of Invasion:

Carried by wildlife, escapes from horticultural plantings

Species Description:

Multiflora Rose is readily identified by its small white flowers and thorny branches. The leaves are opposite in orientation and the flowers occur in small clusters. The plant spreads through small seeds and is able to tolerate a large range of temperatures, climatic conditions and soils. The seeds of this plant are able to spread through birds and are able to remain viable after passing through the digestive tract of birds.

Effects of Invasion: Multiflora Rose forms an impenetrable mat that wildlife and grazers are unable to get through lowering forage quality and decreasing wildlife habitat for all wildlife in the area. It spreads quickly and is capable of fast establishment in area that are not grazed and on the borders of pastures.
Control:

Multiflora Rose can be controlled through an integrated control program that includes mowing both young and mature plants and applying herbicides to the plant after mowing.

It is also possible to apply foliar herbicides such as 2,4-D to the plant. Some control of the Multiflora Rose can be gained through the biological control of rose rosette. This control method stunts the overall growth and development of the plant limiting its life span.
