List of invasive plant species in Pennsylvania

From Wikipedia, the free encyclopedia

Numerous plants have been introduced to the US state of Pennsylvania in the last four hundred years and many of them have become invasive species that compete with the native plants and suppress their growth.

Description

[edit]

Invasive species are often grouped by threat levels that vary from county to county from very high impact to remarkable increased growth. The species below are by no means comprehensive and are listed in type order rather than level of threat[1][2][3]

The Pennsylvania Department of Conservation and Natural Resources ranks invasive species into 3 categories based on urgency of threat. [4]
