Stevens County 2013 Noxious Weed List
Adopted on February
21, 2013 pursuant to RCW 17.10.090-17.10.100
INTRODUCTION:
The Stevens County
Noxious Weed Control Board believes that the prevention and
eradication of newly invading noxious weed species yields the
greatest return for the resource investment. This is best
achieved through an intensive survey and inventory program
allowing for early detection and early action. Education and
awareness are an integral part of prevention and early
detection. Being familiar with what is growing around us is the
best way to assure that when a new invader arrives, it will be
noticed and dealt with at the most effective stage.
During a public
hearing held on February 21, 2013, the Stevens County Noxious Weed
Control Board of Directors voted
to adopt all Class A, all
Class B Designate and certain Class B noxious weeds from
the 2013
WA State Noxious Weed List. Even though we
include all A and B-designate weeds on our County list, only
those that are CURRENTLY FOUND GROWING OR ARE KNOWN TO HAVE
GROWN PREVIOUSLY (reported sightings within the past five years)
in Stevens Co. are listed here. They are divided according to
control requirements:
Section 1)
These CLASS A weeds have been found as single plants or in very limited
populations. Prevention, early detection and eradication is high
priority. Cost share may be available at Board discretion.
Section 2) These Class B Designate
weeds are located in portions of the county in very limited or
moderate populations. Control is required. Preventing seed production, preventing
further spread, reducing existing population sizes, inventory
and education are the priorities. Cost share may be available at
Board discretion.
Section 4) These Class B
Select weeds are normally grown as ornamentals. If they are found to
have escaped intentional landscape plantings and appear to be spreading
off site control may be required
Section 5)
NOTE: Special Control Requirements for the below listed weeds differ
dependent upon location in the county. Read Carefully.These weeds are on the State list as Class B
Designate in some areas of the county. This is due to the heavy
infestations that occur in portions of the county while only light or
moderate infestations occur elsewhere. Outside of the State Designated
areas, we’ve made these weeds Class B Select with control requirements
differing by weed as follows:
plumelessthistle
Carduus acanthoides-
Class B Designate in all areas lying
south of State Highway 20; Class B Select north of State
Highway 20. Control, as outlined in section (2) above, is
required everywhere in the county.
rush skeletonweedChondrilla
juncea-
Class B Designate, with the same
requirements outlined in section (2) above, in all areas north
of Township 29 N. South of here, a control strip at least 40’
wide must be maintained along property boundaries, including
travel corridors
yellowstarthistleCentaurea
solstitialis cost
share '13 -
Class B Designate, with the same requirements outlined in
section (2) above, in all areas except T36 R38 North of Hwy
395/Hwy 20 and West of Pingston Creek Road. Within this area, a
control strip at least 40’ wide must be maintained along
property boundaries, including travel corridors
Section
6) These Class B
Select weeds exist in moderate to heavy populations in much of the
county. To help prevent further spread of these weeds, a control strip
at least 40’ wide must be maintained along property boundaries,
including travel corridors. Beyond this strip, the focus will be on
assisting landowners one-on-one with control recommendations and
technical assistance when requested and utilizing biological control
techniques when available. Understand, these weeds are recognized as
being extremely detrimental, but due to the widespread infestations, we
feel voluntary management is generally the wisest utilization of the
Weed Board’s and landowner’s limited resources.
Section 7) Additionally,
at the discretion of the Weed Board, any site infested with
state listed noxious weeds, whether within an area where the weeds are
normally required to be controlled or not, that poses a threat of the
spread of propagules (seeds, roots, vegetative parts) through the
transport of contaminated materials, may require control and may be
subject to enforcement by the Board. These sites include but are
not limited to gravel pits, quarries, landscape materials, etc.

EACH COUNTY WEED BOARD MUST
adopt all State classified A and B-designate weeds on their County Weed
Lists. However, counties may choose which of the State classified B and
C weeds will be placed on their County Weed List dependent upon the
individual concerns of each county. Additionally, a County Weed Board
may elevate the classification and
corresponding control requirements of any weed on the State Weed List.
NOT INCLUDING A NOXIOUS
WEED ON our County Weed List does not mean that it has no
significant impact or that it is not found in the county. In order to
use resources (time, equipment, dollars) in the most effective and
efficient manner possible, the SCNWCB has chosen to limit the number of
State classified B and C weeds on our county list. Unfortunately,
several of the noxious weeds on the State Weed list are already
established well beyond the point where we feel a significant impact can
be made towards reducing the population of the weed without a
substantial allocation of resources going toward that one weed.
IN THE CASE OF WEEDS
that are well established, wide spread and/or not included on our list,
we feel a strong education/awareness program with an emphasis on
voluntary landowner compliance is the best use of resources. Biological
control agents (usually insects) can be one of the best management tools
for weeds in this category. Many bioagents are already established
in the county and the impact they are having on weeds such as diffuse
and spotted knapweed, Canada, plumeless and musk thistle, rush
skeletonweed and St. Johnswort is visible. The redistribution of
bioagents within the county and the continued build up of successful
agents or introduction of new agents, when available, will be encouraged
and supported by the weed board. Support by the weed board may
include using staff or volunteer labor, purchasing or otherwise making
available appropriate equipment, sponsoring training opportunities and
buying the biocontrols or sharing the cost with landowners as approved
by the Board.
