About
Rosa multiflora, or Multiflora Rose, is a deciduous shrub from East Asia. This plant can grow up to 15 feet long and be used for erosion control, living fences, and providing cover to native wildlife. The dense thickets this plant forms can quickly overrun pastures and crowd out native species.

Ecosystem Impacts
Ecosystem Impacts
Its dense thickets restrict human, livestock, and wildlife movement and crowd out native plants
Creates huge seed banks that can still produce seedlings up to 20 years after the mature plant has been removed (a mature plant can produce half a million seeds in a year!)
Large monocultures decrease native plant and wildlife diversity
Removal Techniques
Removal Techniques
Try to "save the best" -- the areas with the smallest infestations and native species
It's incredibly difficult to restore heavily infested areas because of the huge seed banks mature plants create
Small populations of younger plants can be manually pulled
Remove the entire root system to prevent resprouting
Brush mowers can be used for larger infestations, but will need to be followed up with herbicide treatment
Apply herbicides (glyphosate, triclopyr, or metsulfuron-methyl) until no more plants reemerge
