Non-Native Plants Threatening Ecosystem

(Host) A growing number of non-native plant species are posing a threat to the state's ecosystem as they crowd out indigenous varieties.
Now, an association of Vermont nurseries and landscapers is urging its members to sign a voluntary code of conduct to stop the sale of some invasives that are used as ornamental plants.
Among the plants are Japanese and common barberry, Norway maple and burning bush. They're not yet quarantined by the state, which means their sale is still legal.
Dan Redondo is on the board of Greenworks, the trade association that represents Vermont nurseries and landscapers.
(Redondo) "There's a recognition that at some point in the future these plants will be added to the state's quarantine list which will make them illegal to sell. The idea is to get in front of that quarantine list and get them to voluntarily agree to stop selling or designing or installing these plants."
(Host) Redondo says he expects many, but not all, of his groups' members will sign the voluntary code.
Businesses that do agree to stop selling the plants will be able to display a sign that shows they've signed the code of conduct.
