The City of Portland has taken significant steps to limit the negative effects of invasive species. In November 2005, the Portland City Council adopted Order 36360, which required the city to develop a three-year work plan and 10 year goals to integrate invasive plant management into existing city programs and reduce invasive plant coverage in Portland. The city’s response was the Invasive Plant Strategy, developed in October 2008 and administered by the Environmental Services Invasive Species Program. In 2019, Invasives 2.0 was produced, an all-taxa invasive species plan for the city.
