Animal and Plant Health Inspection Service (APHIS) Plant Protection and Quarantine (PPQ) employees collaborate with many partners, cooperators, and stakeholders to protect plant health. To keep us on the leading edge, PPQ explores scientific frontiers, develops new plant protection methods, and makes critical advancements that safeguard our nation’s agricultural and natural resources while facilitating the safe global trade of agricultural products. These stories highlight some of their most successful and impactful programs and activities.

People ship and receive packages using express courier companies—like FedEx, UPS, DHL, and others—all the time. But when the package includes an agricultural item, things could get dangerous for U.S agriculture and natural resources.

“You should know what could be hitchhiking in or on those items—invasive plant and animal diseases and pests,” said Dr. Mark Davidson, Deputy Administrator of USDA’s Plant Protection and Quarantine. “Once these threats enter our country, they could harm our crops, livestock, and ecosystems. Left unchecked, they could devastate entire agricultural industries, eliminating jobs, threatening our food supply, and costing billions of dollars in losses and response costs.”

It is now illegal to sell, grow, or plant Callery pear (also known as Bradford pear) in Ohio because of its invasive qualities and likelihood to cause economic or environmental harm. There is no requirement for the removal of existing plants, but the Ohio Department of Natural Resources (ODNR) Division of Forestry encourages control and removal to benefit native forest ecosystems.

PlantNative.

PlantNative is dedicated to moving native plants and naturescaping into mainstream landscaping practices. We believe this promotes biodiversity, preserves our natural heritage, reduces pollution and enhances livability. Their goal is to work with nursery owners, landscape professionals and consumers to increase public awareness of native plants and related landscaping practices and to increase both the supply of and demand for native plants.

The PLANTS Database provides standardized information about the vascular plants, mosses, liverworts, hornworts, and lichens of the U.S. and its territories. The database includes names, checklists, automated tools, identification information, species abstracts, distributional data, crop information, plant symbols, plant growth data, plant materials information, plant links, references, and other plant information. The PLANTS database contains native and naturalized plants of the PLANTS Floristic Area (PFA), which consists of North America and all additional U.S. territories and protectorates.
Note: The Invasive/Noxious Weeds data in the previous PLANTS version were outdated and not migrated to the new PLANTS version (new site launched in Spring 2021). A new PLANTS Invasive/Noxious Weeds dataset has been developed and will be deployed to PLANTS in a later release.
