Returning Healthy Plant Communities to Portland
The City of Portland has developed an invasive plant management strategy to improve the health of our natural areas. The goal is to remove invasive plants from 4,000 acres, or 40% of city-owned land, in the next 10 years. Here is some information about how the city plans to enhance plant communities:
- Portland Parks and Recreation is working to protect the highest quality parks habitat by removing small patches of invasive plants. Between January 2007 and December 2008, Parks removed invasive plants from over 1,200 acres of high quality parks to keep these areas in good to healthy condition.
- Environmental Services has developed an early detection and rapid response program to remove small patches of highly invasive plants. These efforts are aimed at preventing new invaders before they become established.
- The Environmental Services Watershed Revegetation Program removes invasive plants and installs native plants on at least 70 acres per year. In the last three years, this program has revegetated an average of 320 acres per year. Each site is managed for at least five years to remove invasive plants and install native vegetation.
- Each year, Portland Parks and Recreation staff organizes over 70,000 volunteer hours of work on natural area stewardship projects. The Environmental Services Clean Rivers Education Program involves about 6,500 students per year in classroom and field exploration, site assessment, and watershed health education.
