Native plants are species that occur naturally in a particular region and are adapted to climate and elevation of a particular area. Native plants are appealing to humans and wildlife and are friendly to their environment.
Why are noxious weeds a problem?
- The problem of noxious, non-native weeds proliferating in Central Oregon is severe.
- Many noxious weeds overrun native vegetation, reducing habitat for other plants and wildlife, destroy ecosystems by altering soil, hydrology, steal scarce water, and increase fire danger.
- Noxious weeds infest crops and cost local communities in terms of visual blight, a reduction of property values and lost agricultural production.
- Some noxious weeds are poisonous to humans, livestock, and wildlife.
- Seeds from noxious weeds are spread by foot and vehicular traffic along our roadways and through our public lands.
- Many property owners unknowingly have these non-native, noxious weeds growing in their yards and fields, which aggravates the situation.
- Sometimes this damage cannot be undone except by sustained effort over decades.

Dalmatian Toadflax, what to know before you pull
Toadflax damage due to weevils
Dalmatian Toadflax Stem Weevil, Mecinus janthiniformis (formerly known as Mecinus janthinus)
Dalmatian Toadflax Stem Weevil, Mecinus janthiniformis (formerly known as Mecinus janthinus): This insect is having a profound impact on Dalmatian toadflax infestations. Adults feed on the foliage and flowers while larvae mine out the stem. Plants are often stunted and tops of the plant are riddled with holes caused by adult feeding. This insect flies well and seeks out new toadflax patches. Because the insects’ only source of food is Dalmatian toadflax, as the density of the weed decreases, the insect’s population also decreases, a classic predator-prey relationship.
Please leave Dalmatian toadflax undisturbed if you suspect weevils are present. The plants will appear to have boring on the stem and may display some damage.
