Rosa Multiflora

Rosa Muliflora:
Rosa multiflora is native range is Japan, Korea and eastern China. They are invasive plants because they form impenetrable thickt that don't allow the native plants to develop. This plant was first introduced in the U.S. in 1866 from Japan and can easily invade open woodlands, forest edges, successional fields and savannas. The Rosa Multiflora is all around the East of the U.S; the only place that Rosa multiflora is not found is in the Rocky Mountains,the south eastern and deserts of California and Nevada. This plant has tolerance for various soil, moisture and light conditions. This plan is bad in NJ because when the birds eat the pulp of the fruit they dropp the seeds, and these seeds rapidly grow and become thick and the only thing that can penetrate them is bulldozers.This plant can be dangerous to us humans but is not dangerous for some wild species like grouse, wild turkeys, cedar waxwings and robins. The leaves and hips are consumed by chipmunks, white-tailed deer, black bears, mice and more. In my opinion Rosa multiflora should be regulated because they are dangerous to us but wild species depend on them,they can reproduce really fast they produce a million seeds a year so when the governement starts to see that there are a lot of them the governemnt should kill some of them that way they wont be that dangerous to us humans and the wild animals can still depend on them.
