Know What Makes an Invasive Species Invasive

L invasive

Invasive species harm our California natives and beneficial exotics. Invasives have one or more of the following characteristics: make lots of seeds, roots, or tubers; leaf out early in the spring; secrete chemicals that inhibit growth of other plants; are an unattractive food source for local wildlife; and are unsusceptible to local plant diseases. Invasive plants have a major impact on the ecosystem, soil, and water. Avoid planting invasive species of these: ice plant (Carpobrotus edulis); periwinkle (Vinca major); purple pampas grass or jubatagrass (Cortaderia jubata or Cortaderia selloana); broom (any kind); cotoneaster (Cotoneaster lacteus or Cotoneaster pannosus).  Learn which local plants to avoid by visiting "Don't Plant a Pest" here. Options for good alternatives to invasive plants are provided here.  Also, if you see an invasive invading a natural area, you can notify the Council by using this email, info@cal-ipc.org.
