The U.S. Department of Agriculture, Animal and Plant Health Inspection Service, Plant Protection and Quarantine Program (USDA, APHIS, PPQ) and the plant health agencies in each of the 50 states, regulate the shipment of nursery and greenhouse stock in an effort to minimize the spread of harmful insects, diseases, and other pests. The Federal & State Quarantine Summaries is designed as a reference tool for nursery stock growers, brokers, purchasers, and others involved in the buying selling, and interstate transport of nursery and greenhouse plant crops. It outlines the basic quarantine and other plant health requirements of APHIS, all 50 states, and the Commonwealth of Puerto Rico and Guam. The information presented here is designed as an aid to help users avoid costly delays, rejections of plant material shipments, and introduction of harmful pests into new areas.

This report reviews developments in state laws and regulations governing invasive species in eleven states. It finds that invasive species laws and regulations are often fragmented and incomplete and have developed primarily on a species-by-species basis in response to crisis. As a result, they often fail to address potential future invaders or close off known invasion pathways. Fortunately, states have begun regulating invasion pathways and identifying species that may become invasive in the future due to climate change or other factors. States are increasingly creating interagency councils and management plans to coordinate these novel invasive species responses.
