Every day, invasive species are threatening the health of our nation’s vital agricultural and natural lands. Forests and rangelands are being infested, cropland production is being negatively impacted, streams and waterways are being choked with weeds, and wildlife species are losing habitat. These conditions are just a few of the negative impacts that will continue, or will become more severe, if successful actions are not taken to halt and/or reverse this trend.

Invasive species are plants, animals, or pathogens that are non-native (or alien) to the ecosystem under consideration and whose introduction causes or is likely to cause harm.
