An invasive species is an organism (plant, animal, fungus, or bacterium) which is non-native to a region.  They have no natural predators and spread quickly, taking over habitat from native species and damaging ecosystems.  They also negatively impact economic and public health.

Yellow Flag Iris Flowers

Yellow flag iris (Iris pseudacorus) clogs creeks, rivers, lakes, and ponds, damaging aquatic habitat and altering water flow.

Invasive species affect all of us.  They reduce property values, increase fire hazard, destroy habitat for native wildlife and birds, reduce populations of native species, accelerate soil erosion and stream sedimentation, reduce crop yield and quality, increase cost for crop production, impact recreational opportunities, and away from the beauty of the landscape.
