Tansy Control Ordinance

Tansy Ragwort – A Noxious Weed

Tansy is toxic and a threat to livestock and agriculture. It spreads rapidly and takes over pastureland, squeezing out grasses and native plants.

Tansy is the only weed addressed by a Del Norte County ordinance. It prohibits persons from allowing tansy ragwort to flower on their property within 150 feet of property lines which border those that are either free of tansy or are being controlled for tansy. See the link in the Resources section below for full text of the ordinance.

Tansy Games

The Del Norte Solid Waste Management Authority has recently begun hosting an annual event called the Tansy Games in an effort to engage the community in removal of these toxic pests. Visit their website to learn more: http://www.recycledelnorte.ca.gov/
