Herbaceous invasive plants are a threat to forest health, productivity, and diversity. This webinar, presented by University of Illinois Extension Forester Chris Evans, explores how to identify common Illinois invasives, tools for controlling these invaders, and new species to keep an eye out...
Forbs
Body
Forbs are herbaceous flowering plants.
Forbs can grow and complete their life cycle in one year, annuals, two years, biennials, or can take 3 or more years to mature and produce flowers and seeds, perennials. Invasive forbs can flower and produce large amounts of seeds that make management difficult.
Invasive Forbs of Concern in Illinois

Restore Natural Areas and Plant Native Species.
After removing invasive species, existing native plants may need help recovering. In some cases, replanting with native plants may be necessary for restoration. When planting native species, try to use local ecotypes of seeds or plants from within 100 miles of your location. Local ecotypes of native plants are adapted to local climates and can be easier to grow. They also provide food and shelter for pollinators and other wildlife.
Restoring diverse native plant communities will help prevent future invasions by strengthening the ecosystem, but continue to monitor for invasive species.
