| Volunteers remove
Japanese knotweed in Tacony Creek Park. |

Invasive plants grow very
aggressively, cover large areas and inhibit the growth of native vegetation. Invasive plants present significant
ecological problems in each of the parks. To reduce this increasing
problem, these invasive species must be controlled in the parks natural
lands. Control methods include cutting, removing root systems
and herbicide applied by a professional. Some invasive plants
that are removed must be bagged and transported out of the park. Examples
of invasive plants include: Purple loosestrife, Japanese knotweed, Garlic
mustard, Ailanthus, multiflora rose, Common reed, Norway maple, Grape vine,
Akebia, Kudzu, Oriental bittersweet and Japanese honeysuckle.
