Includes species listed as a Federal Noxious Weed under the Plant Protection Act, which makes it illegal in the U.S. to import or transport between states without a permit.
PPQ conducts weed risk assessments (WRA) as part of its process for safeguarding U.S. agriculture and natural resources from weeds and invasive plants. A weed risk assessment is a science-based evaluation of the potential of a plant species to establish, spread, and cause harm in the United States. PPQ may initiate an assessment for any number of reasons, including: evaluation of commodity import requests, detection of a new weed in the United States, and petitions for listing from stakeholders.

Whether your pest is a weed, insect, animal, microbe, or another organism, correct identification of your pest makes controlling it easier and often more effective.
Our scientists are developing strategies and methods to manage the brown treesnake and protect endangered species and other wildlife, improve public health, and protect power stations and other sensitive locations from intrusion.

The New York State Department of Environmental Conservation (DEC) and the New York State Canal Corporation today announced a new comprehensive effort, including a new rapid response plan, to combat the potential spread of the round goby, an aquatic invasive species, to the Lake Champlain Basin following the discovery of the fish in the Hudson River near Troy in July 2021. The round goby is one of the biggest threats to New York waters, particularly Lake Champlain, and DEC lists round goby as a prohibited invasive species in the New York Code of Rules and Regulations. Native to Europe and Asia, this fish was introduced in the Great Lakes in 1990, and spread throughout the lakes' system. Round goby reproduces quickly, outcompetes native benthic fish species for food and habitat, eats the young and eggs of other fish, and can transport botulism up the food chain to waterfowl. Working with partners, the agencies will develop a rapid response plan to take effect before the opening of the Canal system on May 20 to identify appropriate actions if round goby enter the Champlain Canal.

The New York State Department of Environmental Conservation (DEC) and the New York State Canal Corporation continue to implement a comprehensive effort, including a rapid response plan [PDF, 1.73 MB], to combat the potential spread of the round goby, an aquatic invasive species (AIS), to the Lake Champlain Basin following the discovery of the fish in the Hudson River near the city of Troy in July 2021. Aquatic invasive species can out-compete native fish species, disrupting ecosystems and damaging local economies dependent on recreation.

The New York State Department of Environmental Conservation (DEC) has announced measures to prevent the further spread of aquatic invasive species in the Adirondacks. Changes to state Environmental Conservation Law became effective on June 8, 2022 and require motorized boat users to obtain certification that they have inspected and removed potentially harmful aquatic invasive species before launching in waters in, and immediately adjacent to, the Adirondack Forest Preserve.

Oak wilt is complex, with a high degree of variability in distribution, severity, and associated management options. This publication provides a detailed overview of oak wilt and is intended to help natural resource managers in the Northeast and Midwest choose the most appropriate tools for a given situation. Using the Story Map format, information has been organized into selectable sections/tabs for easy navigation and exploration.

Bees are declining in the U.S. and with them the pollination services on which people and wildlife depend. Several national forests have begun to include habitat restoration for bees in their forest plans. Justin Runyon, a Rocky Mountain Research Station research entomologist, and Montana State University scientists identified the most pollinator-friendly plants to include in seed mixes for use in restoration projects in the Northern Rockies.
The researchers developed a scorecard that managers can use to select pollinator-friendly mixes based on local factors such as budget, habitat type, or plant availability.
