Invasive Plant Management

The NCR Invasive Plant Management Team treats a meadow in Rock Creek Park.


The National Capital Region Invasive Plant Management Team plans and implements treatments for non-native, invasive plants. The team inventories and maps targeted invasive vegetation, develops control strategies, and, through partnerships, follows treatments with restoration of disturbed areas. The team also conducts outreach and education on invasive plants with park staff, interested volunteers, and community groups.
