一般影响
Munger(2002)报告说：因为种子由鸟类散播，野蔷薇可以长在后期演替森林的间隙，尽管这些森林被认为是相对抵抗外来物种入侵。然而，如果没有大量或经常性骚扰，野蔷薇可能不会是成熟森林的一个严重的长期威胁。野蔷薇可能会被周围的树木和耐遮荫灌木遮荫而无法存活。在北美洲的许多地方，它显然是一个严重的有害植物。它侵袭牧区，降低饲料质量，降低放牧区和农业生产力，并可能导致牛群严重的眼睛和皮肤刺激。野蔷薇能迅速蔓延，其'无法穿越的灌丛'严重限制牲畜进入牧区。它特别茂密的叶片和茎，抑制竞争的原生植物。
地点特有的影响：United States (USA) 
农业: It invades pasture areas, degrades forage quality, reduces grazing area and agricultural productivity and can cause severe eye and skin irritation in cattle (Munger, 2002).
改变演化模式: Munger (2002) states that, "R. multiflora can colonize gaps in late-successional forests, even though these forests are thought to be relatively resistant to invasion by nonnative species."
滋扰人类: R. multiflora can spread rapidly, severely restricting access to pasture and recreational areas with "impenetrable thickets" (Munger, 2002).
竞争: Its characteristic dense growth of foliage and stems inhibits growth of competing native plants (Munger, 2002).
