Scope of Activities 
PPQ takes a lead role for APHIS in 
plant health issues as specialists 
in the safe movement of agricul- 
tural products around the world. 
PPQ also joins with other APHIS 
programs, USDA agencies, and 
Federal partners to mitigate the 
introductions of, and adverse 
impacts caused by, invasive 
species—plants and animals from 
abroad that threaten our ecosys- 
tems. PPQ’s activities can be 
grouped into three categories: 
safeguarding plant and animal 
resources from exotic pests and 
diseases, managing plant pests to 
protect plant resources, and 
enhancing trade through 
phytosanitary procedures. 
Specific actions in support of these 
categories include animal and 
plant pest exclusion, smuggling 
interdiction, trade compliance, pest 
monitoring, risk analysis, and 
areawide pest management, 
including response to emergency 
situations.
