In recent years the Ontario Invasive Plant Council has developed Best Management Practices (BMPs) guides for more than 15 different invasive plants in Ontario. The BMPs provide you with a detailed background history on the plant, how to identify it and how to properly manage it. The series promotes the use of integrated pest management to achieve effective control.

Invasive exotic species present what may be the greatest threat to the long-term health and sustainability of Wisconsin's forests. Human activities such as trading of goods, travel, gardening, and recreation have resulted in the introduction of many non-native plant and animal species to the state. The Council created the Forestry Invasives Leadership Team to develop voluntary best management practices (BMPs) to help control the spread of invasive species.

Collaborative study determines effective messengers, language choices, and modes of delivery for disseminating educational information on how firewood choices can impact forest health. A recent study done in collaboration between The Nature Conservancy’s Don’t Move Firewood campaign and researchers from Clemson University showed that most people in the U.S. don’t know firewood can harbor invasive forest insects and diseases, but when targeted education materials are used effectively, they can learn and are likely to change their behavior.

The aim of this report was to identify the resources, strategies, and policies necessary to create, maintain, and make accessible one or more commodity/invasive species databases that EPA and other relevant agencies can apply to trade policy decision-making in a timely and scientifically-based manner.

Includes best management practices for landowners and resource managers, boats owners and lake managers, anglers, and gardeners.

Provides individuals with the information and tools they need to help prevent the spread of aquatic invasive species commonly found in trade.

Glacier National Park waters are generally open for boating from mid-May through October. All watercraft require an NPS inspection and permit before launching. Prior cleaning, draining, and drying of all watercraft, both externally and internally, will reduce inspection time significantly.

In addition to intergovernmental efforts and research to detect and monitor aquatic nuisance species (ANS), the EPA addresses ANS using numerous regulatory tools.

The EPA's National Pollutant Discharge Elimination System (NPDES) Vessel General Permit (VGP) and Small Vessel General Permit (sVGP) regulate discharges incidental to the normal operation of commercial vessels, including ballast water and hull fouling, which are both pathways for introductions of aquatic nuisance species. The EPA and the Department of Defense are jointly developing the Uniform National Discharge Standards for vessels of the Armed Forces which will also regulate ballast water and hull fouling to help control the introduction of aquatic nuisance species.

Note: On December 4, 2018, President Trump signed into law the Frank LoBiondo Coast Guard Authorization Act of 2018, which includes as Title IX the

It is crucial to keep the mussels from moving from Lake Powell to other lakes and rivers. Utah and Arizona state laws require you to clean, drain, and dry your boat when leaving Lake Powell using self-decontamination procedures. Additional steps are required if you launch on other waters without a significant drying period or if you are on Lake Powell for more than 5 days.

The National Animal Disease Preparedness and Response Program (NADPRP) strengthens our country's ability to combat animal disease outbreaks. Through this program, APHIS provides tens of millions in funding to States, producer organizations, universities, and others to carry out high-value projects that help our Nation prepare for the most critical animal health threats facing U.S. livestock industries today.

Plants for planting can carry a wide variety of pests that are more likely to become established in the U.S. because they are already on a suitable host. In some cases, the plants themselves are the pest. To ensure U.S. import regulations provide adequate protection against the risk posed by plants for planting, the U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (APHIS) established a regulated category called "Not Authorized Pending Pest Risk Analysis" (NAPPRA). NAPPRA allows APHIS to more fully protect U.S. agriculture from foreign pests while minimizing adverse economic and trade impacts. Under NAPPRA, plants for planting must undergo a pest risk analysis before APHIS will authorize the taxon for importation.

Before NAPPRA, APHIS' plants for planting regulations (also known as Q37) categorized imported plants as either prohibited (not allowed) or restricted (allowed under certain conditions). The regulations did not require a pest risk analysis prior to the importation of a new taxonomic group of plants. This differed from APHIS' fruits and vegetables regulations (Q56) where the importation of regulated articles is prohibited until APHIS completes a pest risk analysis.

Under the authority of the Plant Protection Act Section 7721 (PPA 7721), APHIS provides up to $63 million annually to fund stakeholder projects submitted through the Plant Pest and Disease Management and Disaster Prevention Program (PPDMDPP). The projects we fund represent critical needs and safeguard American agriculture and natural resources against invasive plant pests and diseases.  

USDA's Animal and Plant Health Inspection Service (APHIS) was charged with implementing Section 10007 initially part of the 2014 Farm Bill to prevent the introduction or spread of plant pests and diseases that threaten U.S. agriculture and the environment. Under the Farm Bill, APHIS provides funding to strengthen the nation’s infrastructure for pest detection and surveillance, identification, and threat mitigation, while working to safeguard the nursery production system. Every five years, Congress develops and passes a Farm Bill that outlines agriculture and food policy for the country.
