2014, Year-in-Review

As another year comes to a close, program staff have been working to wrap up projects and compile data for 2014.  Many important projects were completed this past season, including control work on Class A noxious weeds, as well as maintaining the control of knotweed (Polygonum spp.) infestations the Skamania County Noxious Weed Control Program has been treating since 2004.  Here are reports on some of the Noxious Weed Program’s projects for 2014:

Class A Eradication Project

Skamania Klickitat County Knotweed Eradication Project

Butterfly Bush Survey

Cooperative Indigobush Control Project

You can also take a look at all projects in our 2014 Annual Report.



Looking to the Future

Every year the Washington State Noxious Weed List is updated to include new species or change the classification of others.  Here’s a look at the changes for 2015:

  • Ravenna grass, Saccharum ravennae, is a Class A noxious weed. More information and pictures here: http://www.nwcb.wa.gov/detail.asp?weed=193
  • Pampas grass, Cortaderia selloana, is a Class C noxious weed. More information and pictures here: http://www.nwcb.wa.gov/detail.asp?weed=195
  • Jubata grass, Cortaderia jubata, is a Class C noxious weed. More information and pictures here: http://www.nwcb.wa.gov/detail.asp?weed=196
  • Italian arum, Arum italicum, is a Class C noxious weed. More information and pictures here: http://www.nwcb.wa.gov/detail.asp?weed=141
  • Shiny geranium, Geranium lucidum, is reclassified from a Class A to a  Class B noxious weed, designated for control by the WSNWCB everywhere except Clark County
  • Dalmatian toadflax, knapweeds (meadow, spotted, diffuse), knotweeds (all except Himalayan), and yellow archangel will be undesignated in Cowlitz County.
  • Wall hawkweed subgenus (subgenus Hieracium) will be undesignated in King County
  • Hoary alyssum will be designated throughout Okanogan County and the designation language for region 4 will be correct now (designated in region 4 except Pend Oreille County and those areas lying north of highway 20 in Ferry County)
  • Scientific names of three species will be updated:
    • Cardaria draba à Lepidium draba
    • Cardaria pubescens à Lepidium appelianum
    • Centaurea jacea x nigra à Centaurea x moncktonii
  • Finally, State Weed Board officer terms will increase from one year to two years under WAC 16-750-130(4).
