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.
Forest managers frequently make decisions regarding the use of pesticides on forest lands. These decisions must be based not only on the effectiveness of these tools, but also on an understanding of the risks associated with their use. For the pesticides commonly used by the Forest Service in its management activities, Human Health and Ecological Risk Assessments (HERAs) are prepared.

The U.S. Fish and Wildlife Service announced a proposal to list the tricolored bat as endangered under the Endangered Species Act (ESA). The species faces extinction due primarily to the range-wide impacts of white-nose syndrome, a deadly disease affecting cave-dwelling bats across the continent.
Bats are essential for healthy ecosystems and contribute at least $3 billion annually to the U.S. agriculture economy through pest control and pollination. The growing extinction crisis highlights the importance of the ESA and efforts to conserve species before declines become irreversible.
