Lewis County Noxious Weed List 2015

The Lewis County Noxious Weed Control Board adopted a new list for the
2015 field season.  The new list includes
four new weeds that were added by the Washington State Noxious Weed Control
Board.

Ravenna grass, Saccharum ravennae
(Class A), Pampas grass, Cortaderia
selloana (Class C), Jubata grass, Cortaderia
jubata (Class C) and Italian arum, Arum
italicum (Class C) are the new additions to the list. Gardeners and landscapers may recognize the
listing of Pampas grass or Jubata grass.
Both have been planted and used in the landscape. Concern for these plants has developed as new
seedling weeds have spread out of gardens and into natural, native plant
settings. The spread of the grasses have
also been documented in Oregon and California.
Photographs, distribution information and background for the new listings
