FAC- Facultative Equally likely to occur in wetlands or non-wetlands (estimated probability 34%-66%). Legacy NPSpecies information may no longer be applicable, please remove if it is not applicable. In legacy NPSpecies Weedy value was Yes with comment: ECOLOGICAL THREAT. In North America, Japanese honeysuckle has few natural enemies which allows it to spread widely and out-compete native plant species. Its evergreen to semi-evergreen nature gives it an added advantage over native species in many areas. Shrubs and young trees can be killed by girdling when vines twist tightly around stems and trunks, cutting off the flow of water through the plant. Dense growths of honeysuckle covering vegetation can gradually kill plants by blocking sunlight from reaching their leaves. Vigorous root competition also helps Japanese honeysuckle spread and displace neighboring native vegetation. (see also Southern Weed Science Society. 1998. Weeds of the United States and Canada. CD-ROM. Southern Weed Science Society. Champaign, Illinois.)
