Effective January 1, 2015 nine weeds were added and nine removed.

Effective January 1, 2015, the following nine weeds were added to the Schedule of Noxious Weeds (a regulation under the Weed Control Act):

Common crupina
Serrated tussock
Wild chervil
Jointed goatgrass
Smooth bedstraw
Wild parsnip
Tansy ragwort
Woolly cupgrass

These non-native weeds were added to minimize their interference to agriculture.

In addition, effective January 1, 2015, the following nine weeds were removed from the Schedule:

Black-seeded proso millet
Nodding thistle spp.
Tuberous vetchling
Goat’s beard spp.
Russian thistle
Yellow rocket
Johnson grass
Scotch thistle
Wild carrot

The weeds are being removed because they are no longer considered significant threats to agriculture and can be managed through modern management practices. These changes will help support pollinators.

 About the Schedule of Noxious Weeds

The Schedule of Noxious Weeds identifies weeds that can seriously damage agricultural land, crops or livestock. If these weeds are growing in a location that negatively impacts agriculture or horticulture, then they must be destroyed.  If you feel that your agricultural or horticultural land is being negatively impacted by noxious weeds, contact your local Weed Inspector.
