Portland's Early Detection/Rapid Response (EDRR) Program focuses on controlling invasive plant infestations while their distribution is limited and patches are small. This approach increases the possibility of eradication and is much less expensive than trying to control well-established invasive species.
The city is managing these species for eradication
The city and its partners are mapping these species and managing them in limited circumstances
The city and its partners are concerned about these species, and encourage landowners to avoid planting them or to manage them carefully
