Shoreline/LFP Noxious Weed Alert

Useful Article This Week fro Shoreline/LFP PATCH -

Of course there are many, many other weeds on the King County Noxious Weed list and others that should be. Such as English Holly, English Ivy, Himalayan Blackberry, Herb Robert, and Bindweed.
English Ivy -
KC Noxious Weed Board

Those listed in this alert are here perhaps because they are the most "noxious" and nasty for humans and
agriculture. But the others may be even more of a threat like English Ivy which is a silent killer of our urban forests.

Shoreline/LFP Weed Alert: Remove These Weeds 

For Your Garden and the Environment

King County property owners are responsible for removing non-native weeds on the county's hit list.

An old adage among gardeners (and botany professors) is that the definition of a weed is any plant you don’t want. That being said, there some weeds that are quite pretty and others that are just an annoyance because you didn't plant them and don't want them. Then there those that are blight to the environment.
Many King County property owners do not realize they have a legal obligation to remove certain weeds from their property. Noxious weeds are separated into classes A, B, and C based on distribution, abundance, and level of threat (how dangerous the plant is to humans, animals, private and public lands, and native habitats).
Noxious weeds are non‐native plants that, once established, are highly destructive, competitive and difficult to control. They have economic and ecological impacts and are very difficult to manage once they get established. So kill ‘em while they’re young is the message here. Non-native invasive weeds across the United States cost an estimated $26.4 billion per year in agricultural economic losses, according to the county.
All Class A weeds must be removed, according to King County Washington State Noxious Weed Law RCW 17.10.
It’s unlikely a property owner is going to be sited for non-compliance of weed removal, but with Earth Day being celebrated April 22, why not lend the local environment a hand by removing invasive exotics that are crowding out native plants? You can find a list of weeds to eradicate at King County’s Noxious Weeds Website. There are also photos and video to help identify the pernicious interlopers.
Here is a short list of the worst offenders on the Eastside:
Tansy ragwort is an invasive, toxic biennial weed from Europe most often found in pastures and along roads and trails. It is a host plant to the larvae of the cinnabar moth who like to munch on its leaves. Problem solved? No, not only will the moth larvae eat the weed, but any Dusty Miller plants you have in the garden also and you will still have the weeds. Tansy ragwort is a Class B Noxious Weed in Washington State and control is required in selected counties in the state, including King County.
