Minnesota: State Information

Minnesota’s $7 billion forestry industry is the State’s fourth largest manufacturing sector, employing more than 90,000 people. If these hungry pests get to a stage where they become unmanageable, our forest and economy could take a turn for the worse. The value of Minnesota’s urban community forests is $760 million, so both rural and urban communities are affected by these pests. Invasive species could also affect our traditional agriculture and produce production. Many of the above pests have the potential to hurt Minnesota crops.


Hungry pests are facing Minnesota from all directions. Keeping invasive species out is the focus of the Pest detection and Response Unit (PDRU) in MDA’s Plant Protection Division. PDRU’s technical specialists are among the Nation’s experts in knowing what pests are threatening our State, the most effective survey methods to detect new pest populations early, and how to effectively respond when a new pest is detected.
