What are plants that require a permit from the USDA for movement into the United States known as?

Plants that require a permit from the USDA for movement into the United States are classified as Federal Noxious Weeds. This designation is important because it helps protect U.S. agriculture and ecosystems from pests, diseases, and invasive species that could disrupt local environments and economies. Federal Noxious Weeds are deemed harmful to crops, livestock, and other native plants, and thus require regulation to prevent their introduction and spread.

To manage these species effectively, the USDA implements restrictions, including permits for their movement, to control their potential impact on agriculture and natural environments. This classification is part of broader efforts to safeguard biodiversity and maintain the health of U.S. agricultural systems.

In contrast, invasive species, endangered plants, and state prohibited plants refer to other categories of plants that may also face restrictions but do not specifically address the federal mandate concerning movement and importation.
