2014 Noxious Weed List

The Lewis
County Noxious Weed Control Board adopted the 2014 County Weed List.  The new list for 2014 includes a couple of
new additions that landowners and citizens should be aware of:

Lesser celandine, (Ficaria verna) or fig buttercup is
a low growing perennial that is visible in the spring and dies back by
mid-summer. Originally introduced as an ornamental, the
species has bright yellow, solitary flowers. It prefers moist ground in open low woodlands,
floodplains, and waste areas. Herbarium
records identify locations Lesser celandine found in King County, Whatcom
County, and Snohomish Counties. There
are a number of cultivars and other species that may be available in the
nursery trade. Fig buttercup is a Class
B noxious weed.

Narrowleaf Cattail, a non-native Typha species and hybrids
include: Typha angustifolia T. Domingensis, T. minima and T. x glauca. The narrowleaf cattail prefers similar wetland
habitats like the native, Common Cattail (Typha latifolia), but is considerably
more aggressive in occupying shorelines.
It is known to occur throughout Washington State including: Whatcom,
Grays Harbor and Pierce counties.
Narrowleaf cattail is a Class C noxious weed.

Russian olive, (Elaeagnus angustifolia) is more
common to Eastern Washington where it is invasive in riparian areas. It is a small tree or shrub with thorny
branches and is now classified as a Class C weed.
